PREFACE<br />

Forage production is the backbone of the livestock industry <strong>and</strong> therefore green nutritious<br />

forages st<strong>and</strong> not only on· the forefront of economic production of animal products like<br />

milk, meat, egg <strong>and</strong> wool, but also support the maintenance of draught power in this era of<br />

energy crisis. The widening gap between the supply <strong>and</strong> dem<strong>and</strong> of green <strong>and</strong> dry fodder as<br />

well as concentrates needs to be bridged.<br />

. The <strong>Indian</strong> <strong>Grassl<strong>and</strong></strong> <strong>and</strong> <strong>Fodder</strong> <strong>Research</strong> Institute, a central organisation, has the<br />

major m<strong>and</strong>ate'[ of developing forage <strong>and</strong> feed resources to achieve the goal of feeding such a<br />

huge livestock wealth in the country. The Institute is engaged in basic <strong>and</strong> applied research on<br />

all facets of fodder crops, grasses <strong>and</strong> grassl<strong>and</strong>s for the development of suitable technologies<br />

ahd their transfer through organised training programmes, field demonstrations <strong>and</strong> other<br />

extension methods. It is in this context that mission oriented research efforts are being made<br />

for the development of economically feasible forage production systems suitable for different<br />

farming situations under various agro-climatic zones of the country.<br />

The present report embodies an account of research results emanated from multidisciplinary<br />

approach in the field of forage production <strong>and</strong> utilization during the year <strong>1984</strong>.<br />

It is expected that the information contained herein will be of immense utility to all those<br />

engaged in the field of forage production <strong>and</strong> utilization.<br />

I express my heartiest thanks to the members of publication committee for compilation<br />

<strong>and</strong> editing, Shri R. B. Mathur for helping in proof reading <strong>and</strong> Shri Munna Singh for<br />

preparation of cover design.<br />

GENERAL<br />

INTRODUCTION<br />

Livestock continues to be the back bone of <strong>Indian</strong> Agriculture, characterised by mixed<br />

farming system involving crop <strong>and</strong> animal enterprises. Feeding of livestock judiciously with<br />

nutritious forages is very crucial for ensuring optimum level of milk, meat, wool <strong>and</strong> egg<br />

production. One of the major factors that limits the expected level of production is the wide<br />

gap between the requirement <strong>and</strong> availability for feeds/forages. Moreover, the increasing<br />

competition between human <strong>and</strong> livestock population for needed nutrients is also causing a<br />

great concern owing to l<strong>and</strong> <strong>and</strong> input constraints. Thus, feeding of huge livestock wealth<br />

warrants Concerted efforts to develop feed <strong>and</strong> fodder resources in the country.<br />

The importance of forages in feeding the livestock, the ever increasing gap between<br />

supply <strong>and</strong> dem<strong>and</strong>, the diversity <strong>and</strong> complexity of the problems <strong>and</strong> their impact on agricultural<br />

economy of the country led to the establishment of the <strong>Indian</strong> <strong>Grassl<strong>and</strong></strong> <strong>and</strong><br />

<strong>Fodder</strong> <strong>Research</strong> Institute, Jhansi towards the end of Third Five Year Plan in 1962 by the<br />

Government of India <strong>and</strong> administered by the <strong>Indian</strong> Council of Agricultural <strong>Research</strong>, New<br />

Delhi from April, 1966.<br />

WEATHER<br />

During the year <strong>1984</strong>, total rainfall of 839.4mm WaS received in 45 rainy days (table 1)<br />

The year was, however, characterised by late onset <strong>and</strong> very early (4th week of August)<br />

withdrawal of monsoon, Thus, the season for kneri] crops was limited to a period of seven<br />

weeks only. Most of the crops, particularly seed crops, were under severe moisture stress <strong>and</strong><br />

therefore, the yields were affected adversely. Absence of rains from September to December<br />

also caused moisture stress to unirrigated winter crops. The year experienced extremely hot<br />

summer <strong>and</strong> the maximum temperature recorded on a single day during Junewas 500C.<br />

RESEARCH HIGHLIGHTS<br />

DIVISION OF PLANT IMPROVEMENT<br />

1. A total of 1305 new accessions of different spe .ies of grasses, legumes <strong>and</strong> other fodder<br />

crops, viz., guar (744), moth bean (224), Melilot us species (24), Macropt ilium lat hyroides<br />

(9), Indigofera species (42), Desmodium species (73), Clitoria species (57),<br />

Atylosia species (63), Phaseolus species (24), Stylosanthes species (4), Amaranthus<br />

species (7), Conaoalia species (2) <strong>and</strong> grasses (12) collected from indigenous <strong>and</strong> exotic<br />

sources were evaluated for different fodder attributes. These were classified into<br />

different group <strong>and</strong> the cultivars with specific desirable attributes were identified for<br />

further studies.<br />

2. In Sorghum a newly developed strain JHS-833 giving 12% higher green yield <strong>and</strong> 10%<br />

higher dry matter yield than SSG 59-3 was observed promising. Transgressive segregation<br />

pattern observed in F 2 generation of a 3 way cross (296 A X PC-40) X IS 2887<br />

revealed the possibility of recovering desirable plant types. Two F 1 hybrids 2219 A y.<br />

AS-l <strong>and</strong> 2219 A X PB 8104-1 exhibiting high positive heterosis <strong>and</strong> hererobeltiosis<br />

for forage yield traits were identified promising,<br />

~. Three newly developed strains of oats, JHO 824, JHO 825, <strong>and</strong> JHO 826 were identified<br />

for testing under An India Coordinated trials. Seven strains, viz., JH0801, 810, 813,<br />

816, 817, 822 <strong>and</strong> 823 were identified promising for single cut <strong>and</strong> five strains,. viz.,<br />

JHO 801, 813, 816, 817 <strong>and</strong> 822 for two cut system based on intial evaluation trials<br />

under the Coordinated Forage Project. Amphiploid progenies of A sativa X A. magna<br />

crosses were subjected to back crossing <strong>and</strong> selfing to recover desirable types combining<br />

traits of both the species.<br />

4. In bajra, JFB 817 <strong>and</strong> JFB 824 were observed to be the best in final yield evaluation<br />

trial. Four new populations were subjected to mass selection <strong>and</strong> improved as JFB 841<br />

II


842, 843 <strong>and</strong> 844. A sweet stalk population JFB 845 was synthesized. SAP 8-1 was<br />

observed to be true breeding for reduced protogyny. A vigorous, leafy brachytic dwarf<br />

segregant was isolated from F 2 progeny. Thirty three progenies of BC 2 selfed generatioQ<br />

of the cross P. americanum X P. orientale wer,e evaluated.<br />

5. F 2 generation of two crosses 42-1 x IL 52 <strong>and</strong> 42-1 X 454 cowpea was raised <strong>and</strong><br />

promising individual plants were selected for earliness <strong>and</strong> erect growth habit. In berseem,<br />

the yield superiority of CPC-3, JHB 44, 64, 137 under normal spacing <strong>and</strong> of<br />

JHB 48,171,247 <strong>and</strong> 801 under wider spacing revealed the presence of genotype X environment<br />

interaction. The multiple regression analysis indicated that simultaneous selec-­<br />

tion for plant height, number of branches per plants <strong>and</strong> number of leaves per plant<br />

was effective for improvement in dry matter yield,<br />

6. Based on dry matter <strong>and</strong> grain yeild the cultivars S-18-1 <strong>and</strong> S-36 were observed as<br />

promising dual purpose types in field bean iLablab purpureuss, Some mutants particulary<br />

the earliness <strong>and</strong> disease resistance were also identified in species. Based on flowering<br />

behaviour, the germplasm of Cajanus cajon was grouped as short season, mid season<br />

<strong>and</strong> late-season types.<br />

7. Three variants of Dichanthium annulatum (<strong>IGFRI</strong>-12-1, 486-1, 491-1) <strong>and</strong> one natural<br />

hybrid between D. annulatum <strong>and</strong> Bothriochloa intermedia showed superior<br />

performance as compared to <strong>IGFRI</strong>-495-1. Two selections viz., <strong>IGFRI</strong> 43-1 <strong>and</strong><br />

<strong>IGFRI</strong> 4-2-1 of Pennisetum pedicellatum showed excellent performance at several<br />

locations in the country.<br />

8. Higher concentration of Ethyl methyl sulphonate <strong>and</strong> nitroso methyl urea, had prononouced<br />

effect on seed germination, shoot <strong>and</strong> root length, dry matter weight <strong>and</strong> other<br />

plant attributes in Sesbania sesban. Considerable amount of abnormalities were observed<br />

in root tip cs lls <strong>and</strong> PMCS in the mutagen treated material.<br />

9. Cytogenetic studies on selected F 4 plants of interspecific h)brid between Atylosia<br />

albicans <strong>and</strong> Atylosia scarbaeiodes revealed close homology between these species. Studies<br />

on F 5 plants of an inter-generic hybrid between Atylosia cojanifolia <strong>and</strong> Cajanus<br />

cajan indicated close relationship between these species.<br />

10. St udies on colchiploids indicated that there was no effect on fertility in C 5<br />

plants of<br />

Sesbania t ctraptera despite a decrease in quadrivalent frequency. C 6<br />

progeny of Atylosia<br />

scarbaeides showed variation in fertility status of individual plants, despite the<br />

fact that all plants showed a euploid chromosomal constitution of 2 n=4 x,=44.<br />

12 )


\<br />

11. Meiotic studies on different accessions of Panium maximum revealed the auto tetraploid<br />

origin of this taxa. A partially asynaptic plant was indentified in an in bred line<br />

11B-45-1-6 of Pen nisetum americanum In oats, cytological studies on 05.6 X 160­<br />

500 intervarietal <strong>and</strong> JHO 802 X A sterilis interspecific F 2 plants indicated normal<br />

meiosis which showed the possibility of gametic selection against irregular numbers.<br />

The irregular behaviour in the expression of three style pistil character in F 2 revealed<br />

the possibility that t~IS character may be controlled by a major suppressor gene.<br />

12. Seed yield in bajra increased significantly with foliar application of 2500 ppm <strong>and</strong><br />

5000 ppm CCC. Oat varieties with lower values of CSI <strong>and</strong> higher values of R WC <strong>and</strong><br />

proline accumulation can grow well under dryl<strong>and</strong> conditions. O.1t varieties JHO 815,<br />

816 <strong>and</strong> Colabah were found tolerant to higher levels of salinity.<br />

13. The studies on the nature <strong>and</strong> extent of plant diseases <strong>and</strong> their control revealed that<br />

varietal response to foliar pathogens <strong>and</strong> treatment did not differ much in sorghum<br />

The study on the effect of cropping pattern on disease development revealed that spread<br />

of leaf spot of guar was checked by the presence of bajra plants, while no such effect<br />

was noticed for b.ijra rust.<br />

14. The studies on effect of different factors on disease development in sorghum indicated<br />

that the m \XimU31 Infection of foliar pathogens occured in early sown crop (10th July)<br />

<strong>and</strong> with temperature <strong>and</strong> humidity range of 22-35 0C <strong>and</strong> 85-95%, respectively.<br />

15. Artificial inoculation studies on su-babool indicated that the disease symptoms appeared<br />

when the trees were inoculated, covered with moist cotton pad wrapped with polythene<br />

sheet with moistening upto 961 hours. Studies on occurence of disease indicated that<br />

Albizia emeta, Albizia procera,. Acsci« tortttts, Acacia nilotica, Hsrdwicki« binnata<br />

were free from any disease symptoms, w:lile infectio.i of LU,t 0.1 Albizia lebbek, powdery<br />

mildew <strong>and</strong> rust on Dalbergia sissoo, coltetotrichum coostci on Leucaena leucocephala<br />

<strong>and</strong> grey leaf spot on Sesbania sesben, S gr<strong>and</strong>if/ora, <strong>and</strong> S acu/eata, was<br />

observed.<br />

16. Cowpea varieties <strong>IGFRI</strong>-45C1, UPC 5286 end UC 9J26 were found resistant to insect<br />

pests. Medi::ago scute/ata <strong>and</strong> Medicago rugosa were observed to contain volatile<br />

material repulsive to lucerne weevil. Important parasites of cowpea aphid, painted bug<br />

<strong>and</strong> stem borer were identified, Feeding was observed to stimulate neurcsecretary acri-.<br />

vity in Hypera Postica anc Co/losobruchus maculatus.<br />

17, Use of neern cake for control of root knot nematode in Sesbania gr<strong>and</strong>i{1ora was found<br />

( 13 )


effect ive since the gall formation was reduced by 50%. Seed treatment wit'i phenormiphos<br />

in 1.0% concentration gwe the least root knot index of Clltorie, cowpea <strong>and</strong><br />

moth bean. Histopathological studies of infected roots of Clitoria ternalea, Sesbnia<br />

spp. moth bean <strong>and</strong> guar revealed delayed development of nematode in resistant plants<br />

as compared to susceptible ones. Lesion nematode (Prety lench us zeae) was observed<br />

to be'highly pathogenic. to su-babool. Spiral nematode (Helicotytenchus dihystera)<br />

was observed to cause severe root damage in Cenchrus cilietis,<br />

DIVISION OF AGRONOMY<br />

1. Studies on intensive forage production programme revealed that Leucaena in association<br />

with hybrid napier can be an ideal crop combination for year round green fodder<br />

supply. Hybrid napier '<strong>IGFRI</strong>-3' proved to be suitable companion crop for growing<br />

in association with Leucaena<br />

2. Sorghum intercropped with shevri gave significantly higher green fodder yield as compared<br />

to maize-l-shevri <strong>and</strong> teosinte-l-shevri,<br />

3. Wheat variety Raj 1555 showed out st<strong>and</strong>ing performance both under open (grain farming)<br />

<strong>and</strong> canopy (agroforestry) systems,<br />

4. Studies on water production function in oat revealed that herbage production increased<br />

progressively withaddition irrigation of 50 mm at each successive stages of growth.<br />

5. In lucerne, irrigation needs to be scheduled at IWJCPE ratio of 0.8 to 1.0 to provide<br />

suitabe moisture environment for higher herbage yields in different cuttings.<br />

6. The investigation on quality of irrigation water indicated that sewage, cattleshed wash<br />

<strong>and</strong> saline water showed good irrigative values for berseem, lucerne <strong>and</strong> m ethe respectively.<br />

The response of oat was better with cattleshed wash.<br />

7. Teosinte can withst<strong>and</strong> the excess moisture conditions beyond one month of growth.<br />

8. The maximum forage yield was obtained with sorghum hybrid 988 at milk stage<br />

',Under rainfedconditions, sorghum-j-stylo produced the maximum forage yield. This<br />

combination recorded 57.6 <strong>and</strong> 14.5 percent higher green fodder <strong>and</strong> 72.7 <strong>and</strong> 12.0<br />

percent higher dry matter yield over pure st<strong>and</strong> of Srylo <strong>and</strong> sorghum, respectively.<br />

9. Cropping system involving Leucaena+S.sudanensE - bt essice gave the maximum<br />

forage yields.<br />

( 14 )


10. Medicago scutellata proved tobe a promising rabi leguminous fodder crop. Similarly<br />

en ry G.E. 1126 was quite promising-in terms of forage biomass production.<br />

11. Among Brect.e-ie decunbens entries, EC 145738 registered the maximum forage<br />

yield under rainfed conditians.<br />

12. The crop ccmbinaton of barley (Karan) with mustard in alternate strips of 4:4 ratio<br />

exhibited the maximum fodder production.<br />

DIVISION OF SOIL SCIENCE<br />

1. Khalif legumes, namely, cowpea, moth <strong>and</strong> guar are sensitive to light curtailment as<br />

these crops produced only 20-25% of their normal yields under 40-50%<br />

;of its normal production., In cereals, teosinte was found to be the least sensitive. to radiation<br />

curtailment. Similarly, oat, barley, Senji, safflower <strong>and</strong> Chinese cabbage were tolerant to low<br />

PA R where as berseern <strong>and</strong> lucerne were sensitive to radiation curtailment during winter<br />

Season. Among perennial forages, napier-bajra hybrid <strong>IGFRI</strong> No.6 was found to be the<br />

least sensitive to radiation reduction. Teosinte l- Cowpea proved more productive with low<br />

PAR availabili ty (70-80%) under intercropping systems, The soil productivity' wa~ greatly<br />

influenced by 4/bizia lebbek association with the result that the grass yielded almost equal to<br />

that ott .ined from open grassl<strong>and</strong>.<br />

2. The screening of salt tolerant forages jgrasses/trees indicated that sodici ty tolerance of<br />

cultivated rsbi forages followed the order of barley, oats, rape, lucerne, berseem <strong>and</strong> senji.<br />

Oat (<strong>IGFRI</strong>-2688, barley (Runa), berseern (8-99-1), lucerne (NDRI selection 1) were found<br />

fairly tolerant to salinity condition. The yields of carrot <strong>and</strong> turnip were not adversely affected<br />

upto a salinity level of 8 mrnhosjcm. Rhodes <strong>and</strong> para grasses were semi-tolerant whereas<br />

Dinanath <strong>and</strong> Setaria wera highly tolerant to soil salinity of 12 mmhosjcm. Sesbania sesban<br />

was found better than t.euceene in saline sodic soil. Dinanath grass was found most tolerant<br />

to soil acidity <strong>and</strong> could be grown without lime application, The maximum forage yields from<br />

maize <strong>and</strong> teosinte were obtained at 75 percent lime re quirement of 6.2 tons/he on soil of<br />

PH 5.1. Setaria sphacelate produced -higher forge yield than napier, guinea <strong>and</strong> rhodes<br />

grasses in acid soil.<br />

3.' Atospi. ilium bres.lense was found to be the best ni trogen fixer in cultivated fodder<br />

species addting 15-25 kg. Njha <strong>and</strong> increasing the yields from 19 to 41~~. Inoculation of grass<br />

seeds with Azospirillt m <strong>and</strong> Azctcbecter spp. improved the seedling emergence, growth <strong>and</strong><br />

( 15 )


productivity. Availability of phosphate from indigenous rock phosphate was enhanced with<br />

the use of phosphate solubilizing bacteria Bacillus polymlxa H() <strong>and</strong> Pseudomc n 1S stricin.<br />

4. The forage yield of sweet clover under tree canopy was less than open system. The yield<br />

reduction of crops could, however, be minimised by the addition of 13 kg Pfha as the efficiency<br />

of phosphate utilization is only 2.7% under tree' <strong>and</strong> 4.5% under open l<strong>and</strong>s in calcareous soil<br />

Moreover, P application decreases bulk density, increases field capacity, organic carbon, available<br />

N<strong>and</strong> P content of soil. Albizia tebbek "as found to be the most suitable tree species<br />

for agroforestr y system in view of its favourable influences on crop yield <strong>and</strong> soil productivity.<br />

Forage yield of oat <strong>and</strong> barley under A/bizia t ebbek was 80% to that of open plots. The<br />

reduction in yield under tree could be minimised with the application of 40 Kg Nfha.<br />

DIVISION OF GRASSLAND MANAGEMENT<br />

1. Studies to find out suitable time <strong>and</strong> method of sowing for grasses, viz., Cencht us<br />

cillerls, Dichanthium annulatum <strong>and</strong> legumes like Stylosanthes hamata <strong>and</strong> S Scabra<br />

revealed that July was the most appropriate time with an optimum seed rate of 4-6 kgfha.<br />

The planting of seedlings gave better establishment as compared to that of rooted slips <strong>and</strong><br />

seed sowing.<br />

2. The dry matter yield was significantly higher in Cenchrus hybrid, Ctvvsooooon<br />

fulvus <strong>and</strong> Heteropogon contortus pastures even with the application of 30 kg. N fha. In<br />

case of letter two grasses, harvesting at 60 days intervals gave the highest dry matter yield.<br />

Compartive studies for the application of fertilizers <strong>and</strong> introduction of legumes with <strong>and</strong><br />

without phosphorus revealed that the increase in dry matter yields in C. cillsris <strong>and</strong> D.<br />

'annuatum was significantly higher with the introduction of S hamata combined with<br />

application of 30 kg P 20.>fha, as compared to control <strong>and</strong> with other legumes.<br />

3. Arhar was found to be the most suitable crop for intercropping with C clilstls for<br />

getting the maximum biomass as compared to moong, guar <strong>and</strong> urd.<br />

4. In studies on natural grassl<strong>and</strong>s to find out suitable method <strong>and</strong> zime of sowing of<br />

legumes, higher dry matter production was obtained through split sowing in the last week of<br />

June in case of legume, viz., field bean.<br />

5. Experimentation with comparative performance of M<strong>and</strong>ya sheep in Dicbsnttvium<br />

pasture with <strong>and</strong> without legumes showed more or less same body weight gain. However,<br />

sheep can be maintained for longer duration in mixed pastures as compared to pure pasture.<br />

6. Studies on body weight gain of heifers in natural grassl<strong>and</strong>s dominated by Setrime­<br />

Heisrop )gon community showed 280 gfheadfd.1Y for a period of three months<br />

( 16 )


(lOth September to 15th December). Average live weight gain was higher @ 275.5 g]<br />

head/day in Haryana calves for a period of 70 days w.e.f. 6th August, <strong>1984</strong>, when the<br />

animals were grazed in a mixed pasture as compared to animals kept on pure herbage<br />

of C cilletls,<br />

DIVISION OF AGRC-SILVIPASTURE<br />

1. The reproductive studies in leucaena species indicated significant variability in flower,<br />

pod <strong>and</strong> seed characters of different varieties. This in turn affected the seed production.<br />

Selection Silvi-4 of t.euceer.e teucocepbele continued to give maximum forage<br />

production- even in the 6th year of its harvesting without loss of its vigour. Natural<br />

hybrids between L. /eucocephala X L. diversifolia have been observed in the plantations<br />

showing growth vigour <strong>and</strong> wide differences in various characters.<br />

2, Dlchrostecbvs clru reo gave a wide amplitude of pH tolerance from 5-10 during<br />

germination phase. Similarly Albizia amara had a tolerance range of pH 3-10.<br />

Potassium nitrate (0.3%) <strong>and</strong> Thiourea (0.2%) were found to improve the seed germination<br />

of A. lebbek,<br />

3. At the age of 13 years, Acacia tortllis gave the peak above ground biomass of 121.1<br />

t/ha at 4 X 6 m spacing in association with C. clleirls under silvipastoral situations.. __<br />

Under the two plant arrangements, A. nllotica <strong>and</strong> A. tortilis showed that with alternate<br />

plant arrangements, the former gave higher growth rate on dry wastel<strong>and</strong>s.<br />

Herdwickie binata gave higher height under pasture combination compared to Albizia<br />

emera but the collar diameter <strong>and</strong> dbh were always higher in the ca~e of latter species. '<br />

4. Under silvipastoral system, Chrysopogon tulvus continued to give persistant growth'<br />

compared to Cenchrus citieris or Sehima nervosum. C. Ciliaris <strong>and</strong> Stvtossmhos<br />

b. ms te gave ideal corr bnaticn with D. cirt refUll(;er silvipastoral system for higher<br />

l<strong>and</strong> pre: uctivity. All lzle W GI, gave h gher survival percentage compared to other<br />

2 species of Albizia. A. pro cere was the lowest. Plant height <strong>and</strong> collar diameter also<br />

followed similar trend. . .<br />

5. In the agroforestry experiments besides the regular crops 'like wheat <strong>and</strong> sorghum<br />

+cowpea, Leucaena gave forage (dry) yield of 5.8-9.4 tlha in E-W<strong>and</strong> NW-ES<br />

orientation. The thinning of Leucaena provided' additional 14:-16.7 tJha firewood.<br />

17 )


The leaf manure of Leuceena with oats crop gave higher nitrogen equivalence <strong>and</strong><br />

showed promise for use as rich source of nitrogen leading to soil build up.<br />

6. In genetic studies on Leucaena, plant height, collar diameter <strong>and</strong> no. of leave, gave<br />

significant positive association with forage <strong>and</strong> fuel production attributes. Positive<br />

hybrid vigour for forage <strong>and</strong> fuelwood yields were observed in the inter varietal crosses<br />

of Leuceene. Gama ray irradiation of seeds did not produce significant variability in<br />

the Leucaena populations at various doses. Self incompatibility was observed in all<br />

the species except L. leucocephala.<br />

DIVISION OF<br />

SEED TECH~OI..OGY<br />

1. In oats, plant height, leaf length <strong>and</strong> width were observed to be important for building<br />

up selection criteria for fodder <strong>and</strong> seed yield. The number of pod bearing branches<br />

was considered important for selecting good seed yielding types in cowpea.<br />

2. Agronomic studies on seed production in cowpea showed that thinner plant population<br />

flower drop <strong>and</strong> pod drop were the main constraints fOI summer seed production.<br />

July 25 <strong>and</strong> August 10 were observed 10 be suitable dates for sowing the crops.<br />

3. In berseem, 1% spray of atrazine was found to improve number of bolls, number of<br />

seeds per boll <strong>and</strong> seed size. A cutting height of 10 cm superimposed with atrazine<br />

spray produced the maximum seed yield. Studies on inter <strong>and</strong> intra-row spacing<br />

revealed that in Setaria sphacelata, the maximum seed yield (68.8 kgjha) could be<br />

obtained with a spacing of 50 em x 30 em while in Chrysopoqon iutvus, the maximum<br />

seed yield (80.7 kgjha) was obtained with 50 em x 50 Cm spacing.<br />

4. Studies on source sink relationship revealed that in cluster bean, moderate dark respiration<br />

<strong>and</strong> good accumulation of sugar in flower would result in high seed.harvest.<br />

In bajra, high sugar content in the beginning was found favourable for increased forage<br />

production <strong>and</strong> contributed less for cob formation.<br />

5. Borax was the best among different chemicals tried <strong>and</strong> it increased the seed production<br />

<strong>and</strong> sugar content in flower in berscern when applied at the rate of 4 gjlitre.<br />

Among the cowpea cultivers, Russian giant <strong>and</strong> UPC 5286 showed high ratio of large<br />

seeds <strong>and</strong> only these two cultivars exhibited 100% germination thus indicating that<br />

large size seeds had high germination'z; <strong>and</strong> better seed vigour as compared to others.<br />

18 )


Studies on effect of different types of containers/bags on germination, seed vigour <strong>and</strong><br />

physiological health after 4, 17 <strong>and</strong> 26 weeks showed that in general, there/was gradual<br />

loss in sed vigour <strong>and</strong> physiological potential during storage. However, .in case of<br />

berseern, there was no effect of storage container on. seed vigour. ,<br />

6. In mustard, higher dose of nitrogen increased the incidence, of sawfly <strong>and</strong> aphid, while<br />

phosphorus <strong>and</strong> potassium decreased the incidence of both the pests. High levels of<br />

fertilizers, however, resulted in' better fodder <strong>and</strong> seed production.<br />

7. Investigation on the efficacy of different insecticides on seed production fromicowpea<br />

<strong>and</strong> M. P. chari in intercropping system showed that crop sprayed with endosulfan<br />

(0.09% a. i.) or carbaryl (0.1% a. i.) gave satisfactory control of leaf hoppers, defoliators,<br />

blister beetle <strong>and</strong> hycaenid butterfly <strong>and</strong> produced maximum seed yield<br />

(10 g/ha).<br />

8. Studies on evaluation of fungicides for controlling seed borne diseases indicated that<br />

soaking treatment with Bavistin (0.25%) for 24 hrs gave' the best seedling emergence<br />

in berseern (Wardan) <strong>and</strong> lucerne (<strong>IGFRI</strong>-S~244) with drying at' room temperature.<br />

Bavistin, <strong>and</strong> Vitavax (0.25%) treatments increased green matter yield <strong>and</strong>, seed yield<br />

significantly in Stylo , lucerne <strong>and</strong> bersseem.<br />

9. Studies on promising insecticides for safflower aphid revealed that 'three insecticidal<br />

spray's (rnonocrotophos 0.08%) at 20 days intervals commencing from 60 days growth<br />

are needed to keep the crop free from aphids.<br />

DIVISION OF PLANT AN'IMAL RELATIONSHip<br />

1. 'Nutritionl evaluation experiments on para grass at two stages, of growth' (45%DM &<br />

75.1 %DM) for cattle <strong>and</strong> buffalo calves showed that cow calves utilized energy yielding<br />

nutrients better than buffalo calves at both stages.<br />

2. l euceere foliage, when given to calves alongwith dry grass (33i67)ensur~d maintenance<br />

of bodyweight, while the Control group of animals recorded Joss of body weight.<br />

3. Grazing crossbred calves exclusively on natural grassl<strong>and</strong>s predominant-with Sehlme<br />

nervosum can support a grow}h rate of 280 g/day.<br />

( 19 )


4. Survey of grassl<strong>and</strong>s in four districts of Bundelkh<strong>and</strong> (Chattarpur, Sagar, Panna <strong>and</strong><br />

Darnoh) conducted during post monsoon months of October/November showed that<br />

the protein content varied from' 5.33 to 9.37%, while lignin varied from 6.18 to<br />

8.48%. The availability of structural carbohydrates did not differ significantly from<br />

district to district. Among the trace elements, the levels' of copper <strong>and</strong> zinc were much<br />

lower than normal <strong>and</strong> iron level was satisfactory.<br />

5. Evaluation experiments on bermuda grass pasture with cattle have shown that this pasture<br />

can support milk production upto 5 kg/day when it was supplemented with either<br />

concentrate mixture at the rate of I kg/animal/day or foliage of Leuceene at the rate of<br />

5kg/animal/day/cattle grazing on natural grassl<strong>and</strong>s to f mature lseileme species) could<br />

sustain milk production upto 3 kg/day when they were given supplementatron of either<br />

1 kg concentrate mixture or 5 kg t.eucsen« foliage/day.<br />

6. Evaluation of sweet sorghum (Rio) fodder based ration for Tharparkar cows <strong>and</strong><br />

Murrah buffaloes of 1st lactation at State Govt: Livestcck farm Bharari showed that<br />

buffaloes utilized nutrients better than cattle. Die.p. <strong>and</strong> T.D.N. consumption (g/kg<br />

w O . 7 5/day) recorded was 6.27,5.55; 88.90 <strong>and</strong> 62.96 for buffaloes <strong>and</strong> cows respectively.<br />

The above ration supported milk production at the rate of 3.54 lit. <strong>and</strong> 2.58 lit.<br />

in buffaloes <strong>and</strong> cattle, respectively.<br />

7. Young goats ..recorded satisfactory growth rates (32 g/day) when maintained exclusively<br />

on Leucaena foliage lopped from trees of more than one year age, during winter<br />

months.<br />

8. Laboratory experiments to determine the influence of wilting on the quality of silage<br />

with different crops showed that when the protein content of herbage was high, wilting<br />

was 'of no advantage but with poor quality forage it improved the quality of<br />

silage.<br />

9. Among the different additive tried for ensilage o~ forages in the laboratory, formic acid<br />

was better then others individually (formalin <strong>and</strong> sulphuric acid). Comparision of mixtures<br />

indicated that formalin + formic acid was better than other combinations tried<br />

for conservation of legumesjgramineceous crops in the laboratory.<br />

10. A comparative study on the laboratory evaluation of Sesbania with Leucaena, tropical<br />

pasture legumes <strong>and</strong> clutivated legumes h.is shown that it compared well WIth all of<br />

11 em in ierms of cl emical attributes (C P, NDF, ADF, Lignin & Silica), <strong>and</strong> in vitro<br />

true dry matter digestibility (lVTDMD). Among different seasons .ned for lopping, the<br />

20 )


maximum quantity of crude protein could be<br />

harvested during monsoon season.<br />

11. Although berseem btiuse contained higher levels of crude protein (8.7%) as compared<br />

to cereal straws (4.7%), the Lignin <strong>and</strong> ADF levels were also higher in berseem bhusa<br />

(12.2% <strong>and</strong> 52.0%) than cereal straws (7.7% <strong>and</strong> 49.1%)<br />

12. Zinc supplementation at the rate of 65 ppm/day in the ration of calves influenced significantly<br />

the efficiency of feed utilization for growth production.<br />

13. Forage legumes, namely, Indigofere astragalina <strong>and</strong> Rhyncosia minima commonly occuring<br />

in natural grassl<strong>and</strong>s, were found to have good potential as livestock feeds. They<br />

supply about 13-16% crude protein <strong>and</strong> did not contain any constituents deleterious to<br />

animal heal tho<br />

DIVISION OF AGRICULTURAL ENGINEERING AND POST HARVE'ST TECHNOLOGY<br />

1. Mathematical models have been established for determining engineering properties viz.<br />

quilibriu:n moisture content, vapour pressure, latent heat of moisture evaporation nad<br />

specific heat of range grasses <strong>and</strong> berseern (Trifolium Alex<strong>and</strong>rinum). Mathematical<br />

mcdel has been developed to determine grass silage density with the known values of<br />

dry matter content <strong>and</strong> height of filling.<br />

2. Significant influence of silo geometry on silage density has been noticed. Though-put<br />

capacity of ensilage cutter <strong>and</strong> silage density have inverse relationship. 45 percent of<br />

30mm chop length gave a grass silage density of 68 kg/m3.<br />

3. Moisture content in the rangeof 9.5 to 13.0 percent, w.b, resulted in minimum (60.61<br />

percent) axial expansion of grass wafers formed at 30 MPa pressure <strong>and</strong> one minute<br />

dwell time.<br />

4. Prediction equations have been developed for estimating soil 'loss from rangel<strong>and</strong>s 0,<br />

3 to 10% slope.<br />

5. A positive relationship was observed between energy input <strong>and</strong> total yield of M.P. Chari<br />

in red soil in the range ef 1680 to 1918 MJ input energy. prot'o'typis:bfl.·foqtge harves­<br />

.er developed at <strong>IGFRI</strong> has given promising results in harvesting' berseem <strong>and</strong> ost<br />

crops. An extended shoe type.furrow was developed <strong>and</strong> found superior to the existing<br />

ones in sowing dry l<strong>and</strong> crops. .<br />

( .21 )


6. Package of improvements consisting M. B. plough, bukhar/bullockdrawn disc harrow<br />

<strong>and</strong> <strong>IGFRI</strong> single row/Aligarh 3-row drill resulted in net saving of over Rs. 400/- per<br />

hectare in tillage <strong>and</strong> sowing operations compared to that of local practice by the farmers<br />

in wheat crop. Positional placement of seed <strong>and</strong> fertilizer sowing of seed <strong>and</strong> DAP<br />

mixture showed better results when compared with sowing seed <strong>and</strong> DAP seperately<br />

using seed-cum-fertilizer dr.ll.<br />

DIVISION OF RURAL ECONOMICS AND BIOMETRICS<br />

1. The weather analysis of B<strong>and</strong>a district indicated that climate in relation to period of<br />

moisture availabi lity for crop growth may be quite useful for crop planning. The 'probabilityanalysis<br />

revealed that maximum weekly rainfall which can be expected with<br />

50% probability in June, July, August <strong>and</strong> September was 1, 116, 135 <strong>and</strong> 63 mm<br />

respective!y.<br />

2. The results of studies on relative economics of forgae crop production were in favour of<br />

cultivation of forage crops in overlapping system with recommended package of practices.<br />

In all the demonstration trials, cost of production of green fodder was found to<br />

Rs, 5.68 <strong>and</strong> the minimum cost of production was Rs.5.42/h9. The input output<br />

ratio was 1:3.5.<br />

3. Economics of forage proIuc.ion system based on date from experiments <strong>and</strong> demonstration<br />

trials laid out at Central <strong>Research</strong> Farm, <strong>IGFRI</strong>, Jhansi showed thaj the total dry<br />

matter production (grass <strong>and</strong> legume mixed pasture) was maximised in the field of<br />

Cenchrus cillerls + field bean planted in 1:1 ratio as compared to 2:1 <strong>and</strong> 3:1 ratios.<br />

Thus, it may be concluded that the mixed pastures of Cenchrus ciliaris <strong>and</strong> field bean<br />

in 1:1 ratio may be established for increasing the production of high quality forage<br />

pastures.<br />

4. The study conducted in five villages of Baragaon block of Jhansi district showed that<br />

the average milk yield per day per animal was 1.40 Iitres in the case of cows <strong>and</strong> 2.04<br />

litres in case of buffaloes under the existing conditions. These villages were adopted for<br />

transfer of forage production technology <strong>and</strong> consequently farmers fed berseem as a<br />

green fodder to their milch animals. The impact of fodder in terms of increased milk<br />

yield, on an average, came to 2.10 litres per day per cow <strong>and</strong> 2.98 lit res p~r day per<br />

buffaloe. The percentage increase in milk yield due to berseem in both cows <strong>and</strong> buffaloes<br />

was about 60 percent.<br />

Stylosanthes Species<br />

Four species of Stylosanthes, i.e. S. humilis, S. bomste, S. qrecitls & S. scabra were<br />

evaluated at monthly intervals from August to January with regard to population density, dry<br />

matter production <strong>and</strong> leafjstem ratio (dry wt. basis). The plant density was the maximum<br />

in S. hamata during August <strong>and</strong> in S. gracilis during September (table 4). Higher plant<br />

population in S. gracilis in September as compared to that in August indicated delayed germination<br />

of this species. The population decreased steadily with increasing size of plants<br />

in successive months in all the species. The density of mature plants per meter ranged between<br />

10-20% of original maximum seedling density.<br />

Irrespective of the plant populatiop. the dry matte~ production per unit area increased<br />

with the age of plant in all the species. S. gracilis maintained a relatively increased production<br />

level until December. Unlike S. graci/is, S. scabra was a hardy <strong>and</strong> slow growing<br />

species with low herbage yield during warm wet monsoon months (August to October) <strong>and</strong><br />

exhibited agressive growth <strong>and</strong> productivity during winter months. Another perennial species<br />

S. hamata was medium in productivity throughtout the period of its growth. S. humllls<br />

an annual species, with growth duration of only four months was slightly better than<br />

S. scabra <strong>and</strong> poorer than other perennials in production.<br />

. .<br />

- .. All the species, except S. seal re were prf'ousely leafy at seedling stage (early monsoon<br />

period). The annual species was an early leaf shedding type. S. scabra appeared to show<br />

erratic trend <strong>and</strong> appeared to be fairly woody in August. This species, turned out to be<br />

profusely' leafy by end of October <strong>and</strong> regained higher stem proportion' throughout winter<br />

Chickory (Cichorium intybus L.)<br />

With a view to exploit Cichorlum intybus (chickory) as fodder, the growth' performance<br />

<strong>and</strong> the fodder <strong>and</strong> seed production potential under varying habitats were studied.<br />

There was a gradual decrease in temperature from October to January followed by gradual<br />

increase till May. A regular decrease in humidity was also observed from October till rainy<br />

season. Main features including physico-chemical characteristics of three study sites were<br />

as under. .<br />

Site i.<br />

Site ii.<br />

Site iii. :<br />

Berseem field having black soil, 37.8% s<strong>and</strong>, 10.51 wilting coefficient <strong>and</strong> 6.5 pH.<br />

Berseern field having red soil, 68.01% s<strong>and</strong>, 5.27 wilting coefficient <strong>and</strong> 7.5 pH.<br />

A fallow field having red soil, 48.2% s<strong>and</strong>, 9.42 wilting coefficient <strong>and</strong> 7.0 pH.<br />

The data (table 5) indicated that relative growth performance of chicory plants was<br />

poor at site II which may be due to the prevailing edaphio-clirnatic factors. 'Interspecific<br />

competetion also had pronounced effect on seed production of chickory. The maximum<br />

numoer of seeds/plant was recorded at site HI (958) followed by that at site II (908), At<br />

site III, plan ts were growing in comperetion free l<strong>and</strong>, whereas at site II, a remarkable mortality<br />

in berseem plants was noticed due to lack of available moisture during post flowering<br />

stage.<br />

The dry matter production was also studied at 15 days interval in order to determine<br />

the reluive growth rate (RGR). The data given below indicated that the maximum dry<br />

matter was produced at 45-60 days gaowth.<br />

PI-2 : BREEDING VARIETIES OF CULTIVATED NON-LEGUMINOUS FORAGES<br />

2.1 : Produciton <strong>and</strong> quality breeding in fodder sorghum (Sorghum bicolori<br />

(D. S. Katiyar)<br />

The promising cultivars viz., <strong>IGFRI</strong>-491. 777, 1328, 4816,6014, HDI <strong>and</strong> HD 2 were<br />

multiplied.<br />

2.2 : Intra <strong>and</strong> interspecific hybridization in Sorghum<br />

(Bhag Mll <strong>and</strong> U. S. Mishra)<br />

Varietal evaluation<br />

Twelve promising strains developed through intra-population selection <strong>and</strong> mass selection<br />

were tested in a yield trial adopting r<strong>and</strong>omised block design with three replications.<br />

M. P. chari was used as control. The data revealed considerable genetic variation for flowering<br />

time, plant height, leaf number, leaf length, leafbreadth, stem thickness, green fodder yield<br />

<strong>and</strong> dry matter yield. The varietal differences were observed to be significant; JHS-,;-833 was<br />

rated the best strain giving 302.8qjha green yield. On dry matter basis, however, JHS-845<br />

was the best (70.95 qjha). On the basis of yield per day, JHS-833 was observed to be the best<br />

producing 3.07 qjha green fodder. Dry matter yield per day was, however, lower than that of<br />

check variety.<br />

Genetical studies<br />

i Hybrid vigour for CUlm <strong>and</strong> leaf characters was studied in Sorghum blcolor X S. blcolor<br />

<strong>and</strong> S bieolor X S. sudenense crosses. Twenty Seven entries including 16 parents (One male<br />

sterile line, 5 promising S. bicolor lines, S. sudanense lines, 2 shoot fly resistant lines <strong>and</strong><br />

3 shoot borer resistant lines) <strong>and</strong> 11 hybrids were studied in a r<strong>and</strong>omised block design with<br />

three replications. Considerably high range of variation was observed both for mid parent <strong>and</strong><br />

better parent heterosis (table 6.) The mid-parent hetrosis<br />

( 31 )<br />

ranged from "'-'33.6 to 123.9% for


plant height, -27.5 to 25.0% for culm thickness, -18.2 to 18'3% for leaf mumber, -23.8 to<br />

42 6~~ for leaf length <strong>and</strong> -36.4 to 45.0% for leaf breadth, The range of variation for heterobettiosis<br />

was trom -j/.4 to 54.2.% for plant height, 37.6 to 10.2% for culm thickness, -24.1<br />

to 15.7% for leaf number, -30.0 to 30.4 for leaf length "<strong>and</strong>-40.6 to 31.6% for breadth.<br />

Two F 1 hybrids, viz., 2219 AxAS-l <strong>and</strong> 22l9AxPB 8104-1 exhibiting fairly height positive<br />

heterosis <strong>and</strong> hetrobeltiosis for most of the'characters studied were identified as promising.<br />

ii Transgressive segregation pattern was studied in Fz generation of a three-way cross<br />

[296A X PC-40] X IS 2887. The observations were recorded on 116 Fz plants <strong>and</strong> on 5 r<strong>and</strong>om<br />

plants in each of the three parents for five culm <strong>and</strong> leaf characters. The data [table 7-9]<br />

revealed the presence of only positive transgressive segregates for plant height, culm thickness<br />

<strong>and</strong> leaf breadth <strong>and</strong> both positive <strong>and</strong> negative transgressive segregates for leaf number <strong>and</strong><br />

leaf length. The highest percentage of individuals showing positive transgressive segrega'ion<br />

was observed for plant heiget followed by that for leaf length, leaf number, culm thickness<br />

<strong>and</strong> leaf breadth. Tr.is suggested the possibility of recovering desirable plant 1ypes following<br />

3-way cross approach.<br />

Advancing of hybrid genera tions<br />

F l generation of 11 crosses involving S. bicotor X S. bicolor <strong>and</strong> S bicoiot X S. sudsnense<br />

combinations were raised <strong>and</strong> studied for different characters.<br />

ii Fz generation of 95 crosses was raised ani 411 individual F z plants from different crosses<br />

were selected <strong>and</strong> their seed harvested to raise plant to row progenies next year.<br />

iii Seventy eight F 3 progenies dervied from 10 crosses we"re raised in sinzle rows <strong>and</strong> evaluated.<br />

Inferior progenies were discarded <strong>and</strong> 28 promising ones were ~Iected to raise F,t.<br />

generation.<br />

iv Two hundred <strong>and</strong> twety four F 4 progenies derived from 150 selected F 3<br />

progenies were<br />

raised <strong>and</strong> studied for different fodder attributes. Seventy promising' progenies were retained<br />

for further testing <strong>and</strong> the rest were discarded:<br />

CR. N. Choubey <strong>and</strong> S. K. Gupta)<br />

(a) Collection, evaluat ion <strong>and</strong> maintenance of germplasm :<br />

Two spring oat genotypes, namely, Pennline-6571 (EC. 159605) <strong>and</strong> Pennlo<br />

(EC. 159606) procured from Pennsylavania (USA) were grown-for .their initial evalution<br />

with respect to different plant attributes. Pennline-fiS'Zl was found to be very<br />

leafy <strong>and</strong> early flowering in comparison to Pennlo. Pennline was also USed in crossing<br />

programme as a promising parental stock so as to breed high yielding .forage"~ats. In<br />

addition, 500 oat lines were grown for maintenance <strong>and</strong> future USe.<br />

ii Evaluation of 20 entries grown in wider row spacing indicated significant variation for<br />

plant height, no. of leavesjplant, leaf wt./plant, stem wt.1 plant <strong>and</strong> total green wt./plant. The<br />

variation in no. of branches/plant, however, was found to be non-significant. The values of<br />

coefficient of variation ranged from 1.6.18 to 31.75 per cent. Eleven entries as compared<br />

to Wardan <strong>and</strong> twelve entries as compared to BL-1 were found to be superior in fodder<br />

yield.<br />

Evaluation of Us progenies<br />

gamma rays indicated that plant height <strong>and</strong> branches/plant showed significant variation with<br />

cv. values of 13.47 <strong>and</strong> 17.14, respectively. No significant variation was obse.ved for leaf<br />

number, leaf weight, stem weight an I total fresh weight p.;r plant.<br />

Biometrical studies<br />

The varieties differed significantly for number of branches/plant, green wt./plant <strong>and</strong> dry<br />

wt /plant in M 1 but only for green wt./plant in M2 generation. Variety x gam rna rays<br />

( 39 )


interaction was found to be significant for plant height, number of branches/ plant, number of<br />

inflorescences/plant, dry wt./plant in M 1 <strong>and</strong> for number of branches/plant, number of leaves/<br />

plant, green wt.jplant <strong>and</strong> dry wt /plant in M 2 generation.<br />

The correlation studies indicated that dry wt./plant was positively associated with plant<br />

height, number of leaves/plant <strong>and</strong> green- wt.jplant in M 2 • The component characters, viz.,<br />

plant height, number of branches/plant <strong>and</strong> number of leaves/plant showed positive association<br />

among themselves. The significant correlations between dry wt./plant <strong>and</strong> component<br />

characters indicated ample pcssibilities to imr rove dry matter yield through the selection for<br />

component characters.<br />

The multiple regression equations, 'multiple correlations <strong>and</strong> coefficients of determination<br />

were worked out using the data of M 2 generation. The value- of coefficient of determination<br />

(75.4) indicated that selection for plant height, number of branches/plant, number of leaves/<br />

plant <strong>and</strong> green wt./plant had the maximum impact on increase of forage yield. Simultaneous<br />

selection for these characters' appeared to be useful for improving dry matter content.<br />

Varietal trials:<br />

Comparative evaluation trials were laid out with pure <strong>and</strong> mixed cropping of 50 selected<br />

lines of pigeon pea with different crops such as Jowar, Til <strong>and</strong> Urd. In the first trial, the<br />

data on flower initiation <strong>and</strong> completion were recorded until December, 84. Based on this<br />

data, the cultvars were grouped as short season, mid season <strong>and</strong> late season crop. The yearly<br />

Season types completed fruit maturity by December, while the late types were still in flowering<br />

during this period.<br />

In the second trial involving pure <strong>and</strong> mixed cropping tr~atments,'extensive [data on<br />

17 plant characters was recorded on five r<strong>and</strong>omly selected plants of each line at the flowering<br />

stage. Wide diversity was observed in days to flowering, total number of nodes on the main<br />

branching, were selected. The cytological stability was recorded in some of the selected<br />

plants raised through single seed/pod descent. Further scope lies in selecting highly nutritrve<br />

cultivars as Atylosia albicans is a good source of protein. Both these species have showh<br />

much homology in their chromosome complements <strong>and</strong> thus indicated close inter-relationship<br />

between them. Recovery of plants with different growth habits has opened the scope for<br />

differential utilization in cropping system. Selected F 5 plant progenies were raised.<br />

2. The tri-specific hybrid (Atylasia albicans X Atylosia scarabaeoidesy »Atylosia cajanitolia<br />

(Heines) was raised. The parental species differing in morphological traits 'are reported to<br />

S~10W interrelationships. The chromosome pairing during meiosis in trispecific F 1 hybrid,<br />

revealed the existence of homology in their chromosome complements. F 1 (trispecific cross)<br />

was recorded to be semi-fertile.<br />

The chromosome pamng observed during mid pachytene between these two species oj<br />

different genera revealed a close relationship amongst them which resulted in the production<br />

of different plant types with varied morphogenetic traits The fertile hybrids scored were selected<br />

for their propagation <strong>and</strong> use in the next generation.<br />

Cytological studies in TrifoHum species<br />

Meiotic studies were undertaken in a tetraploid<br />

(cv. Halfa) <strong>and</strong> two diploid Tielex<strong>and</strong>rlnum (cv. 99-1) <strong>and</strong> Tcsemipilosum (cv. safari). The<br />

cytological investigations revealed that the tetraploid (T. repens)<br />

(211 = 4 x = 32) species Trifolium repens<br />

possessed 1-2 nucleoli <strong>and</strong><br />

the presence of 1 IV + 14 II's was met within majority of the pollen mother cells on an<br />

average. However, 8II's were seen in both the diploid species. Attempts are underway for<br />

making interspecific crosses <strong>and</strong> induction of polyploidy in these Triiolium species.<br />

5.4 Studies on induced polyplords of forage legumes<br />

(S. N. Zadoo)<br />

Studies on C 2 progeny of induced tetraploids of Sesbania tctraptcra<br />

C 2 progeny of Sitetraptera [2n =4 X<br />

=24] was studied for meiotic behavior. The average<br />

association per cell were observed to be 3.6 quadrivalents + 0.3 trivalents + 3.5 bivalems +<br />

1.26 univalents, The maximum possible association of 6 quadi ivalents was observed in 13.3<br />

per cent cells while an association of 12 bivalents was not observed in any cell. A maximum<br />

of 8 bivalents was, however, observed in 13.3 per cent cells. Although there was a decrease<br />

in quadrivalent frequency <strong>and</strong> consequent increase in bivalent frequency from Co to C 2 Yet it<br />

did not affect the fertility status of C 2 progeny, as only 1 to 2 seeds per pod could be<br />

harvested.<br />

Studies on C 6 progeny of induced tctraplolds of Atylosla scarabaeoids<br />

C 6 progency of colchicine induced tetraplods of At ylosia scarabaeodies was studied<br />

for pollen stainability <strong>and</strong> number of seeds per pod, Pollen stuinabiiiry varied from 29.2<br />

to 64.24 percent in tetraploids as compared to 89.5 percent of diploid control. The number<br />

of seeds per pod showed a range of 0-5 <strong>and</strong> average values of different plants varied from<br />

1.33 to 2 83 as compared to 4.23 of diploid (control). To find out the causes of such variation<br />

in fertility, chromosomal constitution of individual. plants representing different fertility<br />

levels was worked out, All the plants studied showed euploid chromosomal constitution<br />

of 2n=44, compared to 2n=22 of the diploids. Varying number of quadrivalents, trivalents,<br />

bivalents <strong>and</strong> univalents were observed in different plants. The maximum number of<br />

( 48


quadrivalents per cell was observed to be 10, The other extreme of chromosomal assciations<br />

was represented by 22 bivalents, Incidentally, the highest association of 10 quadrivalents <strong>and</strong><br />

the lowest association of 22 bivalents was observed in different cells of same plant C 6-23 (table<br />

l Oj'This indicated that different associations of chromosomes are realized at r<strong>and</strong>om <strong>and</strong> have<br />

no re'ationship with chromosome size which is small in this genus. The extent of multivalent<br />

association does not appear to have any relationship with the fertility of the carrier. No<br />

relationship was found between pollen stainability rercenta£e <strong>and</strong> seed setting ability in<br />

induced tetraploids.<br />

The absence of multiple associations of more than four chromosomes <strong>and</strong> low frequency<br />

of trivalents <strong>and</strong> univalents suggested that the tetraploids had a balanced chromosomal constitution<br />

<strong>and</strong> all the chromosomes are represented four times. Thus, the variation in fertility<br />

. could not be attributed to chromosomal constitution of individual plants.<br />

Seeds from individual plants with varying fertility status have been collected <strong>and</strong> will be<br />

sown in the next season to ascertain if there is a segregation for fertility <strong>and</strong> other parameters.<br />

Hybridization involving natural <strong>and</strong> induced tetraploids<br />

Crosses in different combinations including reciprocals involving induced tetraploids<br />

of S. sesban var. 'bicolor' <strong>and</strong>S'. t etraptera as well as natural tetraploids S. microcarpa<strong>and</strong><br />

S. simpliscula were attempted. The flowers in all the cases fell down within 2-3 days of<br />

pollination.<br />

5.5 Cytogenetical studies on cultivated non-leguminoas fodder crops<br />

(M. N. Prernach<strong>and</strong>rnn)<br />

Panicum sp::cies :<br />

Studies on chromosome number <strong>and</strong> meiotic behaviour of 17 accessions of P. maximum<br />

revealed that all the accessions had the chromosome number 2n = 32 The quadrivalents ranged<br />

from 0 to 7 <strong>and</strong> bivalents from 2 to 16. Pollen mother cells with univalents <strong>and</strong> trivalents<br />

were present in all accessions.<br />

The occurrence of 7 quadrivalents indicated the autopolyploid origin of the taxa which<br />

is presently in the process of natural diploidization as is evident from the range of quadrivalents<br />

from 7 to nil <strong>and</strong> the pres;nce of bivalents up to 16.<br />

Pennisetum species:<br />

Fourteen out of 108 genotypes of P. americanum X P. purpureum hybrids were selected<br />

based on their growth vigour, Ieaflness <strong>and</strong> plant height for further evaluation. A plant inden­<br />

• .ified in tred line Jl£-4':-1-6 of P. cmericcnum which lacks in pollen shedding was found<br />

to be panially asynaptic/dcsynaptic. The high percentage of pollen sterility was due to meiotic<br />

abnormalities caused by the resultant univalents. Pollen mother cells of this plant were<br />

having upto 10 univalents alongwith bivalents. The mean chromosome association per cell<br />

was 1.28 ring bivalents+3.l6 rod bivalents+5.12 univalents, The r<strong>and</strong>om assortment of<br />

( 50 )


univalents resulted into pollen with irregular chromosome complement <strong>and</strong> hence pollen<br />

sterility. A few selfcd <strong>and</strong> cross pollinated seeds with lIB-45-1-6 were collected for maintenance<br />

<strong>and</strong> further USe as source of aneuploids,<br />

Using male sterile ICms 81A P. americanum as female parent, interspecific <strong>and</strong> intergenerich<br />

ybridization had been tried with P pedicel/atlim, P. Polystachyon .<strong>and</strong> Cenchrus<br />

ciliaris, No hybrid seeds were obtained <strong>and</strong> hence these were not compatible.<br />

Avena species:<br />

The studies were conducted on A. sativaxA. magna F I<br />

hybrids (2n-;= 35) with five<br />

st-ains of A. sat ita (2n =42) <strong>and</strong> A. magna (2n = 28).TheF 1 with JHO 801 as femal e parent had<br />

the highest number of bivalents <strong>and</strong> lesser number of univalents compared to F I<br />

with OS-6,<br />

OS-7, UPO-94 <strong>and</strong> 160-500. This confirmed that JHO 801 favoured gene exchange from<br />

A. magna to A. sativa due to higher number of crossing overs: :'. . .. "..,c.<br />

T1:e F I h)brids were seIf sterile. The sterility barrier has to be overcome for gene<br />

transfer from A. magna to cultivated A. sativa. By using a 2% colChi~ine by capillary method<br />

shoot meristern, it was possible to obtain such amphiploids in hybrids with OS-6, UPO-94<br />

<strong>and</strong> JHO-801. The seedlings were vigorous with thickened leaves compared to the parental<br />

species. The amphiploids are expected to be fertile <strong>and</strong> by using it as a bridge, it will be<br />

possible to transfer desirable A. magna genes to A. suiioa.<br />

Back crossing of the F 1 hybrids with A.. sativa pollen was done extensively. Few seeds<br />

were obtained in hybrids with UPO-94, OS-6 <strong>and</strong> JHO-801. This showed that even though<br />

pollen is sterile, occas.onal functional female gametes are formed in the PI hybrid. These<br />

back cross hybrids also will have way for introgressicn of advantageous wild genes from<br />

A. magna to cultivated oats.<br />

Cytology of F I <strong>and</strong> F 2 interparietal <strong>and</strong> interspecific hybrids:<br />

The meiotic behaviour ofFj plants with dwarf palestine variety of A. satica having<br />

glume less spikelets <strong>and</strong> compact panicle with A. sativa strains IGO 1094 <strong>and</strong> UPO 160 <strong>and</strong><br />

A. nuda (2n =42), hull less oat with OS-6 were found normal with 21 bivalents <strong>and</strong> normal<br />

tetrad formation. Normal seed get was also observed in the F 1 plants.<br />

Thi rty plants each of OS-6 x 160-500 intervarietal <strong>and</strong> JHO-802 x A. sterilis interspecific<br />

F2 were screened for chromosomal abnormalities. Although the F I plants had meiotic<br />

irregularities, the F 2 plants had normal chromosome complement <strong>and</strong> hence normal meiosis<br />

( 51


which indicated that gametic selection against irregular chromosome numbers would have<br />

taken place.<br />

Three-style pistil in Aisatioa<br />

This spontaneous mutant character observed in A.sativa strain·OS-8 may be of recessive<br />

nature since the F l hybrid between three style plants <strong>and</strong> normal plants had only normal two<br />

styles in its florets. The F l plants had normal meiotlc behavioua with 21 bivalents as that in<br />

mutant <strong>and</strong> normal parents. This showed that no chromosome structural changes were<br />

involved.<br />

The F 2 progeny of plants with three style pistil raised from the primary, secondary <strong>and</strong><br />

tertiary seeds had no significant difference in the percentage of three style pis tilled florets <strong>and</strong><br />

all the plants had three style pistil character as shown below.<br />

Primary Secondary TertialY Total<br />

seeds seeds seeds<br />

%of 3 styled primary florets 26.7 30.6 39.9 31.96<br />

%of 3 styled secondary florets 8.7 2.9 5.9 5.96<br />

There was significant difference in three style pistil character with secondary florets with<br />

very low expressivity. The expressivity in primary florets varied from 5.6 to 62.5% in whereas<br />

in secondary florets, it was only 0 to 14.3%. Out of 30 panicles observed, 13 were without any<br />

three styled pistil in secondary florets although allthe panicles had teat in primary florets. The<br />

irregular behaviour in the expression of three style pistil character revealed the possibility that<br />

this character may be controlled by a major suppresser gene.<br />

5.6 Cytogenetical studies in range grasses.<br />

(M. G. Gupta)<br />

On the basis of morphological data, all the Seven existing lines of Ciglaucus belonged to<br />

the same group. Cisetigerus gerrnplasm was grouped into tall <strong>and</strong> early flowering types (15),<br />

tall <strong>and</strong> late flowering types (5), dwarf <strong>and</strong> early flowering type (9), <strong>and</strong> dwarf <strong>and</strong> late flowering<br />

type (13). Ciciliaris material was grouped into tall, early flowering with purple coloured<br />

spikes (37), tall, early flowering wiro faint colour spikes (12), tall, late flowering with purple<br />

colour spikes (5), dwarf, early flowering with purple spike (18), dwarf, early flowering <strong>and</strong><br />

faint colour 0), dwarf, late flowering with purple spike (12).<br />

( 52 )


Cytological studies:<br />

Chromosome associations <strong>and</strong> ploidy level were studied in nine lines of C. ciliaris,<br />

namely, <strong>IGFRI</strong>-8-2-2; 8-2-4; 358; 338; 660; 671; 678; 679 <strong>and</strong> S-4. The observations<br />

0.1 the meiotic divisions in PMC showed that all the nine lines studied are tetraploid in nature<br />

with chromosome complement as (4X = 24:= 36). Chromosomal associations at dia-kinesis<br />

showed the autotetraploid nature of these cultivars. Chromosomal associations as quadrivalents<br />

forming various patterns, SUCll as, rings, chains, inter associations etc. <strong>and</strong> the occurrence<br />

of eighteen bivalcnts as diakinesis were irrespective of various morphological attributes ex'<br />

pressed by the cultivars.<br />

Studies on apimixis :<br />

Embryological studies were conducted on only four lines, namely, S-4, <strong>IGFRI</strong> 660, 638<br />

<strong>and</strong> 8-2-2. A 11 these lines showed apomictic nature of embryo development. The adventive<br />

embryo rapidly develops from the nuclear tissue <strong>and</strong> obliterates the growth of sexual embryo<br />

<strong>and</strong> assumes its pl-ce.<br />

PHYSIOLOGICAL STUDIES IN FORAGE CROP IMPROVEMENT<br />

Varietal screening <strong>and</strong> induction of drought tolerance in forages.<br />

(R. B. R. Yadava <strong>and</strong> B. D. Patil)<br />

Twelve genotypes of oats grouped into three categories (i) highly drought tolerant (ii)<br />

moderately drought tolerant <strong>and</strong> (iii) susceptible based 011 screening parameters (CSI, RWC<br />

<strong>and</strong> proline accumulation) were grown in field under irrigated <strong>and</strong> unirrigated conditions. In<br />

highly drought tolerant group, the reduction in yield under unirrigated against irrigated conditions<br />

varied from 9.94 to 16.74 per cent (table 12) In moderately drought tolerant grou p,<br />

the reduction in yield varied from 18.05 to 21.15 per cent <strong>and</strong> in drought susceptible group,<br />

it ranged from 22.58 to 27.80 per cent.<br />

6.2 Salt tolerance in forages.<br />

(0. P. S. Verma)<br />

Six varieties of oats, viz., JHO-1315, JHO-S16, DPO-121, OS-86, Colabah <strong>and</strong><br />

Palampur-sl were tested for salt tolerance at four salinity stress levels (4, 8, 12 <strong>and</strong> 16 Ece<br />

53 )


under pot-culture. Salinity levels were simulated by dissolving Nacl, Cac1 2 <strong>and</strong> ~Na2 S04 in<br />

the ratio of 7:2:1 in water equal to the saturation percentage of 18 kg soil in pots. Plant<br />

height was observed to be reduced with the increasing levels oJ salinity in all varieties. However,<br />

an increase in tiller <strong>and</strong> leaf number was recorded at 8 <strong>and</strong> 12 Ece levels in all varieties<br />

except Palampur-I which could not sur vice beyond moderate salinity stress of 4 Ece.<br />

Ear bearing tillers, ear length, spikelet number <strong>and</strong> seed weight per plant increased upto the<br />

salinity levels of 12 Ece in varieties JHO-815, JHO-816 <strong>and</strong> Colabah. The effect of highest<br />

salinity level on grain yield was adverse in all varieties. JHO-815, JHO-816 <strong>and</strong> Colabah<br />

were identified as the most tolerant genotypes as revealed by their survival at the highest level<br />

of salinity.<br />

6.3 Effect of growth regulators on flowering, seed setting <strong>and</strong> quality aspects of<br />

fodder crops<br />

(R. B. R Yadava)<br />

Th~ effect of growth regulators on seed yield in bajra was stadicd, Plant were sprayed<br />

with different levels of growth regulators (1000, 2500 <strong>and</strong> 5000 ppm MH; 2500, 5000 <strong>and</strong><br />

] COOO PFm CCC <strong>and</strong> 25CO, 5CeO <strong>and</strong> 1eceo ppm B-nine) at tillering stage <strong>and</strong> observations<br />

on flowering <strong>and</strong> seed yield contributing characters were recorded. The data (table 12) revealed<br />

that the untreated control plants took 34 days when the first flower emerged. The flowering<br />

time was prolonged by 1 to 12 days in different treatments. The number of ear bearing tillers<br />

per p'ant increased with the application of growth regulators. The highest concentration<br />

(10000 ppm) of cce <strong>and</strong> B-nine showed inhibiting effect, although were better .han control,<br />

Grain yield under 2500 ppm <strong>and</strong> 5000 ppm of MH <strong>and</strong> 5000 <strong>and</strong> 10000 ppm of CCC was<br />

significantly higher than the control. Similarly, 5000 ppm of MH, CCC <strong>and</strong> B-nine had significant<br />

effect on thous<strong>and</strong> grain weight.<br />

with comon leaf spot. These observations indicated the selectivity of pathogens to the<br />

treatment. The effect on the yields (green weight <strong>and</strong> dry matter percentage) was not Significant.<br />

2 Another experiment was conducted to study the effect of cropping patt-­<br />

ern on disease development, Guar <strong>and</strong> bajra cross were raised in 2x2 ill plots of each<br />

crop alternating each other. The rows direction in plots was East to west. Guar was found<br />

affected with Alt erneria leaf spot <strong>and</strong> bajra with rust. The spread of guar leaf spot was checked<br />

by the presence of bajra plants while no such effect was noticed in case of bajra rust,<br />

3 ~everal crosses were attempted between diploid tetraploid <strong>and</strong> hexaploid oats to<br />

7.3 Problems <strong>and</strong> prospects of plant diseases in graminaceous fodder crops.<br />

(Arun Kumar]<br />

Etiology <strong>and</strong> epidemiology of sorghum foliar Pathogens:<br />

Effect of date of sowing on disease development:<br />

To determine the relationship between date of sowing <strong>and</strong> disease development,<br />

variety M. P. Chari of Sorghum was sown in pots at three different dates at an interval of<br />

ten days, i. e. 10 th, 20th <strong>and</strong> 30th July. The per cent leaf area affected by different diseases<br />

<strong>and</strong> yield parameters were recorded at 3-5 leaf stage, <strong>and</strong> at 50% flowering stage in each<br />

treatment. Results showed that the severity of diseases was more on the plants sown on l Oth<br />

July as compared to those sown on later dates. Thus, sowing of seeds on 20th July was<br />

observed favourable because the seeds Sown on this date produced plants with low disease<br />

incidence, greater height <strong>and</strong> higher number of larger leaves/plant. Number of tillers, stem<br />

girth <strong>and</strong> dry wt/fresh wt ratio were also observed at their optima at this time.<br />

Effect of temperature ana humidity on development of diseases in field :<br />

Obs.rvations on three diseases, viz., zonate leaf spot, anthracnose <strong>and</strong> grey leaj<br />

spot were recorded from third week of August to first week .of November to find out<br />

periodic development of these diseases in relation to different weather conditions prevailing<br />

in the field. Results indicated that the maximum infection of the diseases took place between<br />

23. 0 to 35. OoC which is generally available during these months. It was also observed<br />

that high humidity of 85-95% was required for maximum infection of foliar pathogens.<br />

Studies on disease control aspects<br />

Conidia of rough leaf spots iAscochyta sorghina) of sorghum were SUbjected to<br />

different fungicidal treatments in laboratory to observe the per cent inhibition in germination<br />

57 )


· - .<br />

with respect to control in distilled water. The germination took place after 3 hrs, while no<br />

conidia germinated in 100 ppm solution of Vitavax. Benlate (lOa ppm) showed considerable<br />

inhibition (58. 3%). Bavistln (l00 ppm) could not inhibit the germination more than 16.6%<br />

After 24 hrs, benlate successfully inhibited the qermination by 93% <strong>and</strong> bavistin upto 90%<br />

The performance of these three fungicides will now be studied in field conditions.<br />

Artificial inoculation studies <strong>and</strong> pathogenicity test of rusarium acuminatum on<br />

subabool trees.<br />

Attempts were made to inoculate the fungus E. acuminatum isolated from gummosis<br />

affected subabool trees. The isolation was made from infected parts of bark <strong>and</strong><br />

.disintegrated cortical tissues. At the onset of gum production, the affected portion of bark<br />

was wrapped with a surfacesterilised polythene sheet. When the visible symptoms of gum<br />

appeared, the bark was carefully removed the tree by means of a sharp sterilized blade <strong>and</strong><br />

isolated on PDA-meclium. Pure cultures of the fungus were raised <strong>and</strong> the two-week old<br />

cultures were used for inoculation.<br />

The spore suspension having 7-8 spores per (10 X 40 X) microscopic field indicated no<br />

symptoms, The inoculation made by direct application of spore suspension containing 15-16<br />

conidia on one year old subabool trees of peru type (<strong>IGFRI</strong>-8) at a height of about 1 m on<br />

main trunk produced symptoms.. The observations on the inoculated treatments were constantly<br />

taken for 16 days (table 13).<br />

Occi.rrence <strong>and</strong> host range of /ungal diseases on fodder trees.<br />

PI-8: STUDIES ON INSECT PESTS OF FORAGE CROPS, THEIR IMPORTANCE<br />

AND CONTROL.<br />

8.1 Genetic evaluation of important non-leguminous fodders for resistance to<br />

insect-pests.<br />

(S. A. Faruqui <strong>and</strong> K. C. P<strong>and</strong>ey)<br />

One hundred <strong>and</strong> sixty two plants of segregating population of 24-3-1 x 81B along with<br />

their parents were studied for reaction to shootfly. Out of 42 dwarf plants, 17 were resistant<br />

<strong>and</strong> 25 susceptible <strong>and</strong> out of 94 tall plants 18 were resistant <strong>and</strong> 76 susceptible. The type of<br />

resistance appears to be simple.<br />

2. Studies on neurosecretory activity in relation to feeding in Hyperapostica <strong>and</strong> Callosbruchus<br />

maculatus indicated that feeding stimulated the synthesis <strong>and</strong> release of neurosecretory<br />

material.<br />

8.2 Genetic evaluation of important forage legumes for resistance to insect-pests.<br />

(K. C. P<strong>and</strong>ey <strong>and</strong> S. A: ~aruqui)<br />

the lucerne weevil. Five hundred out of 5000 seedlings were selected under adult cotyledon<br />

test. These were put under adult leaf disc test <strong>and</strong> about 350 plants were selected on the<br />

basis of least damage. These were put for larval development test <strong>and</strong> about 250 plants<br />

were selected. These plants were put for ovipositional stumulus test <strong>and</strong> finally about 150<br />

plants Were selected <strong>and</strong> seeds from them were collected,<br />

The crude extract obtained through Steam distillation of Medicago species, namely<br />

M. sativa, M. ariertext a, M. utalica, M. scutellata, M. rugosa, M. murex, M. tarnatae <strong>and</strong><br />

M. truncalula were tested in open cages at strength of 10, 100 <strong>and</strong> 1000 microgramms per disc.<br />

The response ratio of lucerne weevil indicated that M. scut ellata <strong>and</strong> M. rugosa appeared<br />

to produce volatile material which contained substances repulsive to the weevil. M. sativa,<br />

M. intertexta <strong>and</strong> M. arabica extracts contained substance that was attractive to<br />

lucerne weevil.<br />

Tl'n vaneues of cowpea JC-21, 978, 984, 450, 1008,985, VMPKV-1,HY 68-B,<br />

143 <strong>and</strong> 515 were screened for combined resistance to cowpea, flea bettle <strong>and</strong> semi-looper.<br />

JC-21, 1008 <strong>and</strong> 68-B showed combined tolerance for these pests. The cowpea varieties,<br />

'Kanyakuman, <strong>IGFRI</strong>-450, 5286 <strong>and</strong> UPC-9020 had the least attack of the insect pests,<br />

while 5286, VMPKV-1, 97 <strong>and</strong> 216 showed the higher number of :'lsect pests. The association<br />

of arhar increased number of insect pests in cowpea, while association of bajra reduced<br />

their numbers.<br />

8.3 Survey <strong>and</strong> utilization of parasites <strong>and</strong> predators in relation to biological control<br />

of insect-pests of fodder crops.<br />

(S. A. Farul.(ui <strong>and</strong> K. C. P<strong>and</strong>ey)<br />

1. Survey of important parasites of cowpea aphid, revealed that Lcucopis attacked all the<br />

nymphal stages. On painted bug, Anagrus opt abilis, an egg parasite <strong>and</strong> Neogonatopus species<br />

which attacked all nymphal instars were observed. On stem borers in Chilo species, parasites<br />

most abundant on larvae were Bracon albineatus, Adoxomyla heminopla, Chelonus Spp, Pseudalsonya<br />

Spp. In Scsamia ini'erans, the larva parasite observed was Sturmiopsis in/erans.<br />

2. Studies on food unilizaticn <strong>and</strong> consumption by the larvae of lucerne weevil, Hypcra<br />

postica made on 3rd <strong>and</strong> 4th instar larvae indicated that fresh weight gain from begining of<br />

3rd instar to the day preceeding to cocoon formation was 14·16±0.62 mg, in unparasitized<br />

<strong>and</strong> 9.l8±0.28 mg. in parasitized larvae. Dry weight gain from begining of 3rd instar<br />

through cocoon formation was 1.92±03 mg in unparasitized <strong>and</strong> 1.54±0.66 mg in parasitized<br />

larvae.<br />

3. Observations on diapause behaviour of Bathyplectcs curculionis, the most important<br />

parasite of lucerne weevil indicated that both types of diapausing <strong>and</strong> non-diapausing froms<br />

of B. curculionis occurred in the field. The non-diapausing forms of the parasities had Cocoons<br />

light brown in colour <strong>and</strong> diapausing cocoons were darker. The cocoons collected at the<br />

end of February contained more number of diapausing forms.<br />

PI-9 STUDIES ON NEMATODES IN RELATION TO FORAGE AND PASTURE<br />

PRODUCTION.<br />

9.2 Forage crop production of some important cultivated legumes <strong>and</strong> grasses in relation<br />

to plant parasitic nematodes.<br />

(N. Hasan)<br />

( 62 )


Use of neem cake for the control of root-knot nematode infecting sesbania gr<strong>and</strong>iflora.<br />

Seedling grown in nursery beds amended with neem cake in Jurrows (100 g/furrow)<br />

<strong>and</strong> spot treatment (15 g/spot) <strong>and</strong> later grown in naturally infested soil with M. incognita<br />

reduced the gall formation by about 50% <strong>and</strong> increased the growth by 62~~ of S. gr<strong>and</strong>iilora<br />

seedlings as comparable to those obtained when the seedlings were grown in nematicides<br />

treated soil, Further, the single application of neem cake persists for over a period of six<br />

months.<br />

Control of nematodes infecting Clrtoria, cowpea, moth bean <strong>and</strong> oat by seed treatment<br />

with different nematicidcs.<br />

The namaticides, viz., aldicarb. carbofurart <strong>and</strong> phenamiphos each at 0.25, 0.5 <strong>and</strong><br />

1.0% concentration were tested as seed treatment to minimise the toxicity <strong>and</strong> cost for the<br />

control of M. incognita infecting Clitoria, cowpea, moth bean <strong>and</strong> I. vulgaris infecting oat<br />

under field condition.<br />

Phenamiphos at the highest concentration gave the least root-knot index in all the<br />

forage legumes <strong>and</strong> the maximum reduction in the population (85%) of I. vulgarts infecting<br />

oat followed by aldicarb <strong>and</strong> carbofuran. All the chemicals at highest concentration were<br />

also effective in increasing the forage yield.<br />

Population changes of the root-knot nematode M. incognita in<br />

~pp.<br />

relation to different crop<br />

Clitoria, cowpea <strong>and</strong> moth bean caused greater increase in the population of M. incognita<br />

as compared to Sorghum (M. P. Chari), bajra <strong>and</strong> maize. M. P. Chari was found to<br />

the poor host for this nematode. Weed free fallow greatly reduced the population of<br />

M. incognita.<br />

Screening of lucerne species/varieties against M. incognita <strong>and</strong> P. Penetrans.<br />

\ .<br />

Twenty three varieties of 12 species were tested for resistance in pot culture by inoculating<br />

with freshly hatched larvae/nematodes of M. incognita <strong>and</strong> P. penetrans. The cuItivars<br />

showing resistance will be tested in field conditions.<br />

Histopathological studies of resistant <strong>and</strong> susceptible line of Clitoria ternatea, D. aconltif"lius<br />

<strong>and</strong> Sesbania spp. infected with M. incognita.<br />

Infected root sections of resistant <strong>and</strong> susceptible plants revealed that the nematodes<br />

63


penetrated in both types of plant roots, though fewer in number in resistant plants. The<br />

developments of mature females in resistan: plant roots were also observed to be delayed,<br />

Effect of different cruping sequences on the population of plant parasitic nematodes.<br />

The population of root-knot nematode seemed to be increased in cropping sequences<br />

where cultivated forage legumes were grown continouslyas compared to grasses. Grasses<br />

appeared to be good hosts for spiral <strong>and</strong> stunt nematodes.<br />

9.3 Studies on nematode associated with Silvipastoral systems<br />

(M. 1. Azmi)<br />

Lesion nematode, Pratylenchus zeae Graham is very pathogenic to su-baboo1. Leucaena<br />

leueocephala. Farmyard mannure (FYM) was used to assess its effect on the host response <strong>and</strong><br />

host suitability of P; zeae on the su-babool seedlings. The root lesion index on su-babcol<br />

seedlings, showing host response, decreased as the treatment decreased as the treatment doses<br />

of FYM increased (table 14). Drastic reduction in the rate of multiplication of the nematode<br />

(reproduction factor) showing host suitability were observed with 2x 105 ppm dcse of<br />

FYM.<br />

Cenchrus ciliaris has high degree of drought resistance. In favourable conditions (10­<br />

30%) soil moisture <strong>and</strong> IS-350C soil temprature), it facilitates; multiplication of spiral r ermtode,<br />

Helicotylenchus dihystera, which causes severe root damage, thin st<strong>and</strong>s with pale, slender<br />

or dying lewes. Soil samples were collected <strong>and</strong> the nematodes presentwere indentified <strong>and</strong><br />

counted. Range.of population of predominantly occuring nematode H. dihyst era was higher<br />

in the rhizosphere soil of older stocks than in freshly transplanted material (table 15).<br />

The effect of different population density levels (table 16) was studied by inoculating<br />

] 5 days old seedlings. The studies revealed that the significant reduction in the growth characters<br />

of the plants started from the nematode density 100 per 100 ml of soil. Further, with increasing<br />

levels of inoculum density, there was corresponding reduction in 'plant height <strong>and</strong><br />

dry matter weight of plant. Symptoms like stunting, yellowing of the shoot, browning of the<br />

leaves <strong>and</strong> short discoloured dead roots were prominent. Reduction in the yield of plants or<br />

other pathogenic effects were directly influenced by the initial density of the nematode in the<br />

soil. The rate of multiplication of the nematode in soil is again a density dependent<br />

phenomenon,<br />

3 1 Evalua tion of varietal re:;ponse of fot age crops.<br />

(S. N. Tripathi <strong>and</strong> A. S. Gill)<br />

1. Comparative performance of different cereal forages <strong>and</strong> their varieties for fodder production<br />

during khurif season,<br />

It was first year of the experiment. The treatments consisted of three varieties each of<br />

rmize (Ganga-5, Vijay composite <strong>and</strong> African tall); pearl millet (Rajko, Giant <strong>and</strong> L-74) <strong>and</strong><br />

fodder sorghum (P.C. 6, Pioneer-98 <strong>and</strong> M.P. Chari) along with teosinte. The experiment<br />

was carried out on a s<strong>and</strong>y loam soil intermixed with murrum in r<strong>and</strong>omused block design<br />

with three replicates. Fertilizers @ 90 kg. N<strong>and</strong> 30 kg. P 2 0 5!ha were applied to all treatments<br />

at the time of sowing. The crops were sown on July 18 <strong>and</strong> harvested for forage after<br />

74 days of growth.<br />

Results showed that on an average pearl millet recorded maximum forage yield (389 q<br />

a.M. <strong>and</strong> 88.7 q!ha D.M.) followed by sorghum (346q G.M. <strong>and</strong> 73.8 q!ha D.M.) <strong>and</strong><br />

maize (315 q G.M. <strong>and</strong> 62.2 q!ha D.M.). The forage yield of teosinte was lowest (249 q<br />

G.M. <strong>and</strong> 53.3 q!ha D.M.). Among different cereal forage varieties, African tall in maize<br />

(323 q G.M. <strong>and</strong> 71.5 q/ha D.M.); Pioneer-98 in sorghum (390 q G.M. <strong>and</strong> 83 q!ha D.M.)<br />

<strong>and</strong> L-74 in pearl millet (430 q G.M. <strong>and</strong> 98'1 q!ha D.M.) were found significantly superior<br />

to the other varieties.<br />

2 Comparative performance of guar varieties for forage yields under summer conditions.<br />

It was first year of the trial <strong>and</strong> five guar genotypes Were tested for their forage yields<br />

under summer conditions in r<strong>and</strong>ornised block design' with four replications. The crop was<br />

<strong>and</strong> Rajko) were tested for their forage yields during summer season. The experiment was<br />

planned in r<strong>and</strong>omised block design, replicated eight times. The crop was sown on March 28<br />


yield of pea. However significant response to phosphate fertilization was seen only upto 60 kg<br />

P 205/h1.. Increase in the forage yieid of pea at this level of phosphate manuring were 74 q{ha<br />

Oa{ha <strong>and</strong> control (174.6 q G. M. <strong>and</strong> 39.6 q/ha D. M.) Interactions among levels of phosphate<br />

<strong>and</strong> seed rates were statistically not significant.<br />

2. Effect of cutting intervals <strong>and</strong> stubble height on the forage yield of lucerne<br />

(<strong>IGFRI</strong>-S-244l<br />

The treatments consisted of all combinations of four cutting intervals viz.<br />

3, 4, 5 <strong>and</strong><br />

6 weeks <strong>and</strong> three stubble heignts (4, 8 <strong>and</strong> 12 ern) from the ground level. The experiment<br />

was carried out on light textured soil in r<strong>and</strong>ornised block design with three replicates. All<br />

treatments were fertilized @ 20 kg N + 90 kg Pz 0 5 + 30 kg K 20{ha at the time of sowing.<br />

The trial was sown on October 17 <strong>and</strong> one common cutting was taken after 55 days of sowing.<br />

The cuttings intervals were imposed after ihe first harvest of the forage. In all 8, 6, 5 <strong>and</strong><br />

4 cuts were obtained respectively from cuttings 3, 4, 5 <strong>and</strong> 6 weeks interval. Results showed<br />

that harvesting the crop for forage at an interval of five weeks was optimum as it recorded<br />

the highest green forage yield of 612 q/ha (147 qjha D. M.). Increasing the cutting interval<br />

to six weeks did not prove advantageous. Harvesting the crop at three weeks interval produced<br />

lowest forage (285 q G. M. <strong>and</strong> 51 q/ha D. M.). Frequent cuttings at an interval of<br />

three weeks resulted in gradual reduction in plant population count.<br />

3. Effect of levels of nitrogen <strong>and</strong> seed rates on the forage yield of fodder sorghum<br />

(Hybrid 988)<br />

The experiment was initiated in Kharif season <strong>and</strong> the experimental design was r<strong>and</strong>omised<br />

block with three replications. The treatments consisted of all combinations of 3 nitrogen<br />

level~..J30, 60 <strong>and</strong> 90 kg/ha) <strong>and</strong> 3 seed rates (30,40 <strong>and</strong> 50 kg/ha). The crop was sown<br />

on June 8 in rows 25 cm apart <strong>and</strong> half the nitrogen dose was applied at sowing by drilling<br />

just below the ssed <strong>and</strong> remaining dose was top dressed after taking the first cut. In all two<br />

cuts of green fodder were taken on August 2 <strong>and</strong> October 1.<br />

On pooled basis (total of 2 cuts), linear response to N was observed on the green<br />

fodder yield. Aplication of 90 kg N Iha recorded a green fodder yield of 511 q/hd., whicn was<br />

47.6 percent <strong>and</strong> 8.9 percent greater than the yield observed with 30 kg <strong>and</strong> 110 kg N f'rta<br />

69 ).


espectively. Similarly, with an increase in seed rate fCHTI 30 to 50 kg/ha, the green fodder<br />

yield also increased significantly <strong>and</strong> 50 kg seedjha registered the highest green fodder yield<br />

of 510 q/ha, which was 36.7 percent higher than the yield recorded with 30 kg/ha Seed rate.<br />

Interaction between N levels X seed rate was found to be significant <strong>and</strong> maxium green fodder<br />

yield (547 q/ha) was obtained with 90 kg N<strong>and</strong> 50 kg seedj ha.<br />

4. Effect of nitrogen <strong>and</strong> sulphur fertilization on the forage yield of maize (Vijay<br />

composite).<br />

The rrial was conducted for the first year with treatments T 1 : sulphur 50 kg/ha;<br />

T 2 : 30 kg N/ha; T 3 : 60 kg N/ha; T 4 : 90 kg N/ha; T 5 : T 1+T2 ; T 6 : T 1 + T 3 <strong>and</strong> T 7 :<br />

T 1 + T 4: In all 7 treatments were evaluated in a r<strong>and</strong>ornised block design, replicated 3 times.<br />

The best crop was maize (Vijay) sown on July 25 in rows 25 em apart with 60 kg/ha seed<br />

r.ite. Sulphur <strong>and</strong> full dose of N as per treatments were applied as basal just below the<br />

seed. The crop W'lS cut for green fodder yield on Septcrnbef 15.<br />

Significant differences were achieved among the various treatments for green fodder<br />

yield of maize. On an average, sulphur fertilization (50 kgjha) increased the green fodder<br />

yield by 17.4 percent as compared to no N application whereas application of Sulphur-l- N<br />

increased the green fodder yield by 70.5 percent as compared to only sulphur alone. Interestingly,<br />

application of 50 kg S/ha+90 kg N/ha (T 7 ) recorded a green fodder yield of 303<br />

q/ ha as compared to a yield of 264 q /ha obtained with only 90 kg N /h~l (T4) which shows all<br />

increase in the yield by 14.7 percent.<br />

5. Studies on sulphur fertilization in perennial cultivated cereal fodder crops.<br />

Treatments comprising sulphur application (50 kp./ha <strong>and</strong> no sulphur) <strong>and</strong> three perennial'<br />

cereal foddercrops (Hybrid naoier, N<strong>and</strong>i grass <strong>and</strong> Guinea grass) were compared in<br />

r<strong>and</strong>omised block design with four replications. The perennial crops were spaced 50 x 50 cm<br />

(established during February 1983) <strong>and</strong> fertilized with 60 kg Nfha on May 2 <strong>and</strong> top dressed<br />

@ 30 kg N /ha after I, II <strong>and</strong> III cuts. Sulphur was also applied on May 2 <strong>and</strong> thoroughly<br />

mixed with the top layer. In all, 4 cuts Were taken (June 6, July 23, October 1 <strong>and</strong> NOVember<br />

11) for green fodder yield.<br />

On the basis of pooled data for green fodder yield, SUlphur (50 kg/h:t) increased the<br />

green fodder significantly as compared to no sulphur treatment. Application of sulphur<br />

( 70 )


ecorded a green fodder yield of 1709 q/ha as compared to no sulphur yield of 1532 qJha,<br />

(a difference of 177 qJha). Significant differences also existed among the cereal crops for<br />

green fodder yield.<br />

Interaction between sulphur X cereal crops was found to be significant <strong>and</strong>. maximum<br />

green fodder yield (2073 qJha) was achieved in guinea grass with the application of (50 kgJha)<br />

sulphur.<br />

(M. S. Raut <strong>and</strong> A. S, Gill)<br />

1. Effect of nitrogen <strong>and</strong> phosphorus fertilization at different seeding rates on forage<br />

production of berseem.<br />

This experiment was conducted in order to find out the effect of nitrogen <strong>and</strong> phosphorus<br />

fertilization <strong>and</strong> seed, rates on fodder production of berseern. Treatment combinations<br />

comprising two levels each of nitrogen (10 <strong>and</strong> 20 kg N Jna) phosphorus (60 <strong>and</strong>' 80 kg P2<br />

05/ha) <strong>and</strong> seeding rates (20 <strong>and</strong> 25 kgJha) were evaluated in 32 factorial R.BO, replicated<br />

three times. Berseern var. 99-1 was sown by broadcast method on November 23.<br />

Fertilizers were applied as basal as per the treatments. The crops 'Was harvested- for fodder<br />

on January 20 <strong>and</strong> February 29 <strong>and</strong> left for seed production afterwards.<br />

The experimental results indicated that green <strong>and</strong> dry fodder yield of berseern were<br />

not affected significantly due to application of 20 kgJha over IO kg NJha <strong>and</strong> 80 kg P205Jha<br />

over 60 kg P205/ha However, 20 kg NJha improved green fodder yields to the tune of<br />

10 percent over 10 kg N Iha. Higher seed rate (25 kgJha) resulted in significant increase<br />

in green <strong>and</strong> dry fodder yields of berseern over 20 kgj ha seed rate. The magnitude of such<br />

increases were 40.5 q/ha green fodder <strong>and</strong> 5.3 q/ha dry fodder yields. The interaction between<br />

phosphorus levels <strong>and</strong> seed rates was significant for dry fodder yields. which indicated<br />

that 60 kg P205Jha <strong>and</strong> a seed rate of 20 kgJha gave significantly higher dry matter yield<br />

over 20 kgJha seed rate but at 80 kg P 205/ha. The difference in fodder production due to<br />

20 <strong>and</strong> 25 kgj ha seed rate was not significant. Similarly, the interaction seed rate X nitrogen<br />

levels was also .significant for dry fodder yield. It was observed that the highest dry fodder<br />

yield was obtained with 20 kg NJha <strong>and</strong> 25 kgJha seed rate. At 20 kgJha seed rate, application<br />

of 20 kg N/ha did not increase the dry fodder significantly ove 10 kg N/ha bur with 25<br />

kgjha seed rate it led to significant increase in dry yield over 10 kg N/ha.<br />

2. Effect of bio fertilizers on berseem production.<br />

The experiment was carried out to find out beneficial role of inoculation of berseem<br />

seed with bacterial culture on fodder production <strong>and</strong> nitrogen saving. Treatment combinations<br />

comprised three nitrogen levels (0, 20 <strong>and</strong> 40 kg N {ha) <strong>and</strong> two levels of seed inoculation<br />

(no seed inoculation <strong>and</strong> seed inoculation with bacterial culture). The experimental<br />

design was r<strong>and</strong>omised block with five replications. The crop was sown on December'""12 with<br />

a basal dose of 80 kg P20s{ha <strong>and</strong> 2 cuts were obtained.<br />

Green <strong>and</strong> dry fodder production of berseern was not affected significantly due to seed<br />

inoculation (bacterial culture) over uninoculated seed. With regards to nitrogen response,<br />

an application of 20 kg N{ha improved green fodder yields of berscem significantly over the<br />

control (table 16).<br />

3. Sulphur fertilization in berseem.<br />

This experiment was conducted to find out the effect of sulphur application on fodder<br />

production of berseern, Treatments consising of 5 levels of sulphur (0, 15, 30, 45 <strong>and</strong> 60 kg<br />

SJha) were evaluated in r<strong>and</strong>ornised block design with four replications. Berseern var, 99-1<br />

was sown on December 3. An uniform application of 36 kg N+90 kg P205!ha through<br />

DAP was done at the time of sowing. The.crop was harvested for two cuts upto March 8;<br />

Sulphur application improved fodder production of berseem significantly. An application<br />

of 30 kg Sjha significantly increased both the green <strong>and</strong> dry matter yields over no<br />

sulphur treatment (table 17).<br />

3.3 Cropping patterns for maximum forage production.<br />

(S. N. Tripathi)<br />

1. Evaluation of different forage crop rotations<br />

The treatments comprised nine forage rotations viz. (1) P. pedicel/alum-lucerne, (2)<br />

P. pedicel/arum + guar -- berseem, (3) P. pedicellatum-s- cowpea -- oat. (4) 'maize - lucerne,<br />

(5) maize + guar (6) maize + cowpea- berseem (7) M. P. Chari + guar - oat, (8)<br />

M. P. Chari + COwpea - lucerne <strong>and</strong> (9) M. P. Chari - berseem (control). These crop sequ~<br />

ences were evaluated for their forage production potential in r<strong>and</strong>ornised block design keeping<br />

four replicates. Pure cereal <strong>and</strong> leguminous forage were fertilized with 90 kg N + 30 kg P2<br />

0 5 <strong>and</strong> 20 kg N + 80 kg P205Jha respectively. Mixed crops of cereal <strong>and</strong> leguminous forage<br />

during Kharif season received 55 kg N + 40 kg P205jha. Among different forage crops<br />

rotations' P. pedicel/alum + guar - berseem recorded maxium green forage yield (1249.6 qJ<br />

ha, which was significantly highe r than the green forage yield of remaining rotations. Next in<br />

order were M. P. Chari - berseem (1189.4 qjha) <strong>and</strong> P. pedicel/alum-lucerne (1160.0 q/ha).<br />

There was no significant difference with respect to dry matter yIelds of .he above mentioned<br />

forage rotations which ranged from 200.4 q to 207.9 qjha. The remaining forage crop rotations<br />

recorded around 1000 qjha green forage <strong>and</strong> below 194 qjha dry matter. Maize-]- guar-oat<br />

rotation recorded significantly lower forage yields (840.6 q G. M, & 165.2 qJha'D. M.) than<br />

( 73 )


other rotations.P. pedicellatum (529.2 q/ha G. M. <strong>and</strong> 101.8 q/ha D. M.)<strong>and</strong> berseem(742.2<br />

q G. M. <strong>and</strong> 103.6 q/ha D. M.) were identified as most productive crops during kharif <strong>and</strong><br />

rabi seasons, respectively,<br />

2. Evaluation of cereal-oat <strong>and</strong> legume-oat rotations <strong>and</strong> determination of nitrogen<br />

requirement of oat.<br />

Five forage crop sequences, viz., M. P. Chari-oat, P. pedicellatum - oat, guar - oat,<br />

ccwpea - oat <strong>and</strong> fallow - oat were evaluated for forage yields <strong>and</strong> nitrogen requirrnent of<br />

oat. The experiment was conducted in a split plot design, keeping Kharif fodder crops in<br />

main plots <strong>and</strong> oat with differential nitrogen in sub-plots during rabi season.<br />

Results showed that there were significant differences in forage yields of kharif crops,<br />

P. pedieellatum recorded maximum forage yields (573.6 q G. M. <strong>and</strong> 112.3 qfha D. M.)<br />

followed by M. P. Chari (385.6 q G. M, <strong>and</strong> %.2 qj ha D. M.); Cowpea (318_q G. M. <strong>and</strong><br />

65.8 q/ha D. M.) <strong>and</strong> guar (251.4 q G. M ..<strong>and</strong> 52.6 q jha D. M.) Forage oat grown with<br />

different l~vels of nitrogen (0, 40, 80 <strong>and</strong> 120 kg Nfha) performed differently after various<br />

khari/ crops. On an average, oat aftelcowp~a recorded maximum forage yield (340.5 q<br />

G. M, <strong>and</strong> n.9 q/ha D. M.). which was significantly higher than 01t yields obtained after<br />

M. P. Chari (267.3 q G. M. <strong>and</strong> 55.8 q/ha b. M.), P. pedicellaium (279.6 q G. M. <strong>and</strong> 59.5<br />

q/ha D. M.) <strong>and</strong> guar (293.8 q G. M. <strong>and</strong> 62.1 qfha D. M). The di Terences between oat<br />

yield obtained after cowpea <strong>and</strong> fallow (318.2 q G. M. <strong>and</strong> 70.5 qfha D. M.) <strong>and</strong> M. P.<br />

Chari <strong>and</strong> P. pedicellctum were not significant. P. pedicellatum-oz: rotation recorded<br />

maximum forage yields (853, q G. M. <strong>and</strong> 171.4 q/ha D.1y1.) which was significantly higher<br />

than others. Fallow-oat. rotation recorded significan t1y lower forage yield (318 q G. M. & 70.:><br />

q jha D. M.) as compared to other forage sequences. The forage yield of M. P. Chari-oat<br />

rotation was 652.7 qjha (141.7 q.ha D. M.) followed by cowpea-oat (658.5 q/ha G. 1\1. <strong>and</strong><br />

139.7 q/ha D. M.) <strong>and</strong> guar-oat (545 q G..M. <strong>and</strong> 114.7 q/ha D. M.) Application of<br />

increasing levels of nitrogen to oat increased forage yields <strong>and</strong> on an average use of 40, 80<br />

<strong>and</strong> 120 kg N/ha increased forage yields by 87.2 (20.6 q/ha D. M.); 156.3 (38.1 qfha D. M.)<br />

<strong>and</strong> 188.9 q/ha (43.1 q/ha D. M.) respectively over control (191.8 q(ha G. M. <strong>and</strong> 38.8 q(ha<br />

1. Response of senji to phosphorus application at varying seeding rates under partially<br />

irrigated conditons.<br />

( 74 )


This experiment was initiated in rabi 1983-84 'in order to fino ou(lhe response of<br />

senji to phosphate application at different seeding rates. Treatment combinations comprising<br />

two levels OS phosphorus (30 <strong>and</strong> 60 kg P205jha) <strong>and</strong> three seed rate (25, 35 <strong>and</strong> 45 kgjha)<br />

were evaluated in r<strong>and</strong>omised block desigi with five replications. Senji variety S-76 was<br />

. I<br />

sown on October 19 in rows 30 em apart. Uniform application of 20 kg Njha was done at<br />

the time of sowing. The crop was harvested for green fodder on February 21. .<br />

It was observed that green <strong>and</strong> dry fodder yields were not influenced significant due to<br />

varying seed rates' An application of 60 kg P205jha resulted in significant improvement in<br />

fodder over 30 kg ·P205jha. Plant height, leaf: stem ratio, root length <strong>and</strong> root volume<br />

'were not appreciably affect id due to phosphorus or seed rates.<br />

The interaction between phosphorus levels x seed rates was significant for dry matter<br />

yield, which indicated that at 25 <strong>and</strong> 35 kgjha seed rate significant response to P application<br />

was noticed upto 60 kg P205jha but at 45 kgjha seed rate the response was restricted to 30<br />

kg P205jha only.<br />

2. Effect of nitrogen <strong>and</strong> sulphur application on fodder production of safflower under<br />

d ryl<strong>and</strong> conditions.<br />

The experiment was conducted in rabi 1983-84. Treatments consisted of- the combinations<br />

of 4 levels of nitrogen (0, 25, 50 <strong>and</strong> 75 kg N Iha) <strong>and</strong> 2 levels of sulphur (0 <strong>and</strong> 30,<br />

kg ~jl;1a). These treatments were tested in r<strong>and</strong>omised .block design with 3replica,tipns.<br />

Safflower val'. 7-13-3 was sown at a row distance of 30 em on October 13 <strong>and</strong> harvested on<br />

January 9.<br />

The experimental results indicated that green fodder yield of safflower was not affected<br />

due to nitrogen <strong>and</strong> sulphur application significantly over control: However, dry fodder<br />

yield was significantly increased due to application of 25 kg Njha over the control. Highest<br />

dry fodder yield was recorded with 50 kg N jha but it was at par with dry fodder yields obtained<br />

with 25 <strong>and</strong> 75 kg N fha.<br />

,<br />

3. Effect of nitrogen <strong>and</strong> sulphur application on fodder production of sarson under dryl<strong>and</strong><br />

conditions.<br />

This experiment was conducted in rabl 1983-84 with an objective to find out the effect<br />

of sulphur <strong>and</strong> nitrogen fertilization 011 fodder yield of sarson, Treatments consisted of the<br />

combinations of 3 levels of nitrogen (0, 30 <strong>and</strong> 60 kg Njha) <strong>and</strong> 3 levels of sulphur (0; 25<br />

( 75 )


<strong>and</strong> 50 kg/ha) in r<strong>and</strong>omised block design with 3 replications. Sarson var. Chinese cabbage<br />

was sown on October 7 <strong>and</strong> harvested for fodder flowering stage.<br />

The experimental results indicated that the application of 30 kg N /ha increased green<br />

fodder yield of sarson significantly over the control. However, application of sulphur did<br />

not exhibit any favourable effect on fodder production of sarson.<br />

\.<br />

4. Performance of hairy vetch for forage yield under varying levels of phosphorus.<br />

Treatments comprised five levels of phosphorus (0, 15, 30, 45 <strong>and</strong> 60 kg P205/h:J.)<br />

in r<strong>and</strong>omised blcck design with four replication. The vetch was sown on November 12 in<br />

rows 25 em apart· Basal fertilization comprised 20 kg N/ha applied along with the P levels<br />

drilling just below the seed. The crop was harvested for green fodder yield on February 4.<br />

Application of phosphorus significantly increased the green fodder <strong>and</strong> dry matter yields<br />

<strong>and</strong> the response was significant at 30 kg P 205/ha with yield levels of 226 q/ ha <strong>and</strong> 58.5 q/ha,<br />

respectively.<br />

5. Studies on Medicago scut ellata,<br />

Field trial was conducted on the phosphate requirement of Medicago scut ellcta (L)<br />

Mill (common name, snail medic) during the rabi Season. Treatments consisted of five levels<br />

of phosphorus (0, 15, 30, 45 <strong>and</strong> 60 kg P 20/sha) in a r<strong>and</strong>omised block design with four<br />

replication. The crop was sown on November 27 in rows 40 em apart using 15 "kg seed rate<br />

fha. The experiment was harvested for green fodder yield on Februry 15.<br />

The results indicated that the green fodder <strong>and</strong> dry matter yields were significantly<br />

affected due to the application of phosphorus. The response was linear. Maximum green<br />

fodder (205 q/ta) <strong>and</strong> dry matter (50.62 q[ha) yields were recorded with the application of<br />

60 kgP205[ha.<br />

6. Cutting management studies in fodder sorghum (Hybrid 988)<br />

Treatment combinations consisting of 4 stages of cutting (Boot, 50% flowering, Milk<br />

<strong>and</strong> dough) <strong>and</strong> two stuble height (at the ground level <strong>and</strong> 15 em above the ground level)<br />

were laid out in r<strong>and</strong>omised block design, with three replications. The crops was sown on<br />

July 21 in in rows 25 cm apart, using 40 kg seed rate/ha, Basal fertilization comprised 60<br />

( 76 )


kg N<strong>and</strong> 30 kg P205jha. The crop was harvested for green fodder yield as per the<br />

treatments.<br />

Maximum green fodder yield (3E4 qjha) was obtained at milk stage <strong>and</strong> the reduction<br />

took place beyond this stage. Milk stage recorded significantly higher green fodder yield' over<br />

rest of the treatments. Stuble height was found to be significant in increasing the green<br />

fodder yield. Cutting the crop at the ground level (344 qjha) was found to be superior<br />

over cutting at 15 em above the ground level (322 q/ha).<br />

7. Mixed cropping studies in stylo <strong>and</strong> cereal fodder crops under rainfed conditions.<br />

This was the first year of the trial. Treatments consisting of T 1 : Stylo (S. hamata):<br />

T2 : Maize (Vijay) 50x20 em; T 3 ; Sorghum (Hybrid 988) 50>


dressed 30 days after sowing. The genotypes were harvested for green fodder yield on October<br />

9. C. E. 1126 recorded the highest green fodder yield (520 qjha) followed by G. B. 1759<br />

(464 qjha) <strong>and</strong> G. E. 1768 (464 qjha)against tha general mean yield of 372 qjha.<br />

10. Performance of Cenchrus varieties for forage yield under rainfed conditions.<br />

This was the second year of the experiment. During the period under report the cutting<br />

was taken on October 18 for green fodder yield. Maximum green fodder yiele (206 qjha) was<br />

obtained with variety <strong>IGFRI</strong>-S-3108.<br />

11. Evaluation of Brachiaria spp- for forage production.<br />

This was the second year of the trial. During the period under report, two cuttings(July<br />

23 <strong>and</strong> September 28) were taken for green fodder yield.<br />

In the first cut significant differences were not registered among the five geno~ypes of<br />

B. decumbens, However, maximum green fodder yield (246 4jha) W.lS achieved with entry EC<br />

145725. In the Second cut significant differences were obtained <strong>and</strong> maximum green fodder<br />

yield 068 qjha) was obtained with entries EC 145737 <strong>and</strong> EC 145738.<br />

On pooled basis, no significant difference existed among the genotypes, However,<br />

maximum green fodder yield (383' qjha) was registered in entry EC 145738.<br />

3.5 Forage producton through cr"p <strong>and</strong> varietal blends selected on the basis of crop<br />

(M' S. Raut anp A. S. Gill)<br />

1. Effect of blending of lucerne varieties for forage yields.<br />

Treatments comprising of three lucerne varieties(An<strong>and</strong>-2, composite-S <strong>and</strong> <strong>IGFRI</strong>-244)<br />

<strong>and</strong> their possible combinations were evaluated in r<strong>and</strong>omised block design replicated four<br />

times. Total six cuts were obtained.<br />

Data indicated that in first cut, mixture of An<strong>and</strong> 2+ composite-S gave the highest<br />

green fodder yield 001.8 qjha) as against pure st<strong>and</strong> of An<strong>and</strong> 2 (91.2 q/ha) <strong>and</strong> composite-S<br />

(92.5 q/ha), Thus, an additional yield advantage of 10.9 per cent was achieved through this<br />

( 78 )


mixture over their pure st<strong>and</strong>s. Simi la r trend was noticed<br />

yield differences were not statistically significant.<br />

in second cut also. However; such<br />

<strong>Fodder</strong> production of An<strong>and</strong>-2 (total of 6 cuts) was significantly superior to <strong>IGFRI</strong>-244<br />

but was at par with composite-5. On the b isis of total yield in six cuts, none of the mixtures<br />

tested were found to be significantly superior to pure st<strong>and</strong>s of these varieties. Amongst<br />

mixtures, An<strong>and</strong> 2+ Composite-5 was significantly superior to composite-5 +<strong>IGFRI</strong>-244.<br />

2, Mixed cropping studies in berseern,<br />

In order to harvest good fodder yield from first cut of berseem through growing compatible<br />

associate crops such as sarson, oat <strong>and</strong> triticale, this experiment was initiated during rabi<br />

1983-84. Treatments consistedz seeding rates of berseern (20 <strong>and</strong> 25 kg/ha) <strong>and</strong> 3 mixed crops<br />

tsarson var. Chinese cabbage, oat var. Kent <strong>and</strong> triticale) alongwith pure berseem.<br />

<strong>Fodder</strong> production at initial cut was significantly higher when berseem was mixed with<br />

sarson (191.0 q/ha green fodder <strong>and</strong> 16.8 q/ha dry matter) as compared with pure berseem<br />

(91.5 q/ha green fodder <strong>and</strong> 8.3 q/ha dry mutter). The other two mixtures i.e. berseem + oat<br />

<strong>and</strong> berseem + triticale did not impart significant improvement in fodder yield over pure<br />

berseern at initial cut. It was interesting to note that the fodder, combined of both the components,<br />

remained unaffected though the berseern yield reduced to 45 per cent as compared to<br />

pure st<strong>and</strong>; but, an additional yield of mixed crops (27 to 140.5 q/ha of green fodder),<br />

compensated this loss. This was also true for total production of 2 cuts.<br />

- .<br />

A seed rate of 22 kg/ha was significantly superior to 20 kg/ha wilh respect to fodder<br />

yield in initial cut of berseern but such difference was obscured in total production.<br />

Fan-AGE/PASTURE<br />

4.1 Crop water use <strong>and</strong> lrrrgatlon management.<br />

(Menhi Lal <strong>and</strong> N. P. Shukla)<br />

Studies on water production functions in oat.<br />

The investigation with nine irrigation schedules phytophased at Critical growth stages<br />

( 79 )


(crown root initiation-CRI, tiller initiation, late tillering, jointing, panicle primordia initiation<br />

-PPI, boot, flowering <strong>and</strong> dough stages) was conducted in second year with an objective of<br />

establishing quantitative relationship between water supply <strong>and</strong> herbage accumulation.<br />

The result revealed that the highest green matter yield of 534.5 qjha was obtained<br />

with irrigations at all the growth stages. But this treatment was at par with that of missing<br />

irrigation at dough stage which inturn did not differ statistically from moisture deficit both at<br />

flowering <strong>and</strong> dough stages. However, all stages irrigation accumulated significantly highero<br />

dry matter of 130.6 qjha as compared to remaining treatment. Moisture deficit either at dough<br />

or both at flowering <strong>and</strong> dough stages produced similar level of dry matter indicating that<br />

withholding irrigation beyond boot stage did not exercise significant effect on dry mater<br />

production -in oat. Both green <strong>and</strong> dry matter yields increased progressively with additional<br />

irrigation of 50 mm at each successive stage of growth. Moreover, the magnitude of increase<br />

upto boot stage in green matter <strong>and</strong> only upto jointing stage in dry matter suggesting. that<br />

green matter production is more sensitive to moisture deficit than dry matter accumulation.<br />

The relative leaf turgidity increased with increasing number of irrigations at advanced stages<br />

<strong>and</strong> attained a value of over 90% due to continuous irrigation upto boot stage. Thereafter<br />

there was very small change in relative water content.<br />

Therefore, the herbage accumulation in oat can be increased progressively by scheduling<br />

irrigations at each of the physiological stages upto boot stage to meet the crop water<br />

requirement.<br />

2. Response of lucerne varieties to irrigation regimes.<br />

This was the first year of the investigation in which three lucerne varieties (Sirsa-P,<br />

An<strong>and</strong>-2 <strong>and</strong> <strong>IGFRI</strong>-S-244) were evaluated at five moisture regime'> (IW JCPE ratio of 004,<br />

0.6, 0.8, 1.0 aud 1.2) in R. B. D. replicated three times with a view to working out the<br />

optimum irrigation schedule for higher herbage productivity, st<strong>and</strong> persistency <strong>and</strong> water use<br />

efficiency.<br />

The maximum green <strong>and</strong> dry matter matter yields were recorded In second <strong>and</strong> the<br />

lowest in fourth cut. The lucerne varieties did not exhibit significant variation in total forage<br />

productivity but <strong>IGFRI</strong>-S-244 produced the highest green (399.3 qjha) <strong>and</strong> dry matter<br />

( 61.9 qjha ) yields. The yield levels of Sirsa-9 <strong>and</strong> An<strong>and</strong>-2 were practically the same. It<br />

was noteworthy that An<strong>and</strong>-2 <strong>and</strong> <strong>IGFRI</strong>-S-244 maintained their persistency during rainy<br />

Season whereas Sirsa-9 was completely wiped out indicating that the former two strains<br />

possess the ability of withst<strong>and</strong>ing the climatic <strong>and</strong> edaphic adversities such as high humidity,<br />

80 )


poor aeration <strong>and</strong> weed infestation which are the maior limiting factors in the maintenance<br />

of perennial lucerne.<br />

The green <strong>and</strong> dry matter production increased with increasing soil moisture regimes upto<br />

IW /Ct>E ratio of 10 at which the highest yields were obtained (426.4 q/ha G.M. <strong>and</strong> 69 q/ha<br />

D. M. ) Further increase in the irrigation regime to a ratio of 1.2, however, depressed the<br />

yield. The magnitude of increase also increased up~o IW /CPE ratio of 0.8 <strong>and</strong> declined<br />

thereafter.<br />

Thus, among the lucerne varieties evaluated, <strong>IGFRI</strong>-S-244 holds greater promise<br />

for forage productivity. Moreover, An<strong>and</strong>-2 <strong>and</strong> <strong>IGFRI</strong>-S-244 also possess the tolerance<br />

charicieristics to maintain their persistency during rainy months. Irrigation needs to be<br />

scheduled at IW!CPE ratio of 0.8 to 1.0 to provide suitable moisture environment for higher<br />

herbage accumulation in different cuts.<br />

3. Response of forage bajra to phasic moisture regimes.<br />

The investigation was carried out in the first year with nine treatments involving<br />

varicus ccmbinations of sub-optimum (25% ASM) optimum ( 50 % ASM) <strong>and</strong> superoptimum<br />

(75% ASM) soil moisture regimes during three distinct growth 'phases (establishment.<br />

vegetative <strong>and</strong> reproductive) with a view to identifying the sensitive crop phases to<br />

moisture deficit <strong>and</strong> working out suitable moisture environment for higher herbage production<br />

in giant bajra.<br />

'<br />

The maintenance of super optimum moisture regime during all the growth phases<br />

resulted in significantly highest green matter production (600 q/ha) <strong>and</strong> dry matter accumulation<br />

(153.1 q/ha). This was followed by the treatment involeing super-optimum <strong>and</strong> suboptimum<br />

levels of soil moisture during establishment of vegetative <strong>and</strong> reproductive phases<br />

respectively (505. 6 q green <strong>and</strong> 128. 9 q dm/ha) which did not differ significantly from super<br />

optimum-,sub-optimum-optimum <strong>and</strong> optimum-optimum-optimum combinations during<br />

corresponding moisture condition during corresponding developmental phases. It was evident<br />

that keeping sub-optimum moisture condition during establishment stage produced<br />

lower forage yield.<br />

These observation, therefore, suggest that super-optimum level of soil moisture should be<br />

maintained during establishment phase coinciding with periods of high evaporative dem<strong>and</strong>.<br />

On the other h<strong>and</strong>, during, vegetative <strong>and</strong> reproductive phases experiencing comparatively<br />

high humid period optimum <strong>and</strong>/sub optimum moisture regimes may be considered suitable<br />

tor rationalizing water use in summer Sown bajra.<br />

4. Effect of soil moisture variation on forage yield <strong>and</strong> water me of diferent sorghum<br />

varieties.<br />

The response of 4 sorghum varieties (Pioneer, HD-2, J69 <strong>and</strong>, PC-6) to 3 moisture<br />

regimes (rainfed, 50 <strong>and</strong> 75% ASM) was studied in R. B. D. replicated thrice to workout<br />

ptimum level of soil moisture for higher herbage accumulation in forage sorghums.<br />

The result revealed that variety FC-6 produced the highest green (421 q/ha) <strong>and</strong> dry<br />

matter (149.7 q/ha) yields <strong>and</strong> was followed by HD-2 in green matter (371.6 q/h1) ;ar.d by<br />

J6Q in dry matter (109.9 q/ha) production. The varieties, however, did not differ significantly<br />

in green forage yield but the differences in dry matter accumulation were statistically<br />

significant. On the basis of per day productivity, however, HD-2 was as good as PC-6<br />

in dry matter <strong>and</strong> proved superior to PC-6 in green matter production. The relative leaf<br />

turgidity percentages in PC-6, J69, HD-2 <strong>and</strong> Pioneer were 92.7, 85.0, 78.9 <strong>and</strong> 72.8~.~ respectively<br />

indicating that longer the duaration of variety, greater was the relative leaf<br />

turgidity.<br />

Available soil moisture at 75% produced significantly higher green (425.9 q/ha) <strong>and</strong><br />

dry matter (124.9 q/ba) yields as compared to rainfed treatment but was statistically at par<br />

with 50% ASM (376.4 q/ha G. M. <strong>and</strong> 110.8 q/ha D. M.). The crop maintained unr'er<br />

rainfed condition produced lowest forage (326.4 q/ha G. M. <strong>and</strong> 96.7 q/h~ D. M.). The<br />

leaves from rainfed, 50 <strong>and</strong> 75% ASM exhibited relative water content. of 77.9, 82.3 <strong>and</strong><br />

87.1 % respective ly. This therefore, suggests that the increasing soi I moisture regimes enables<br />

the plants to maintain higher ceil water content.<br />

Thus the sorghum vatieties PC-6 <strong>and</strong> HD-2 hold greater promise for forage productivity<br />

<strong>and</strong> soil. moisture regime well above 50% ASM appears to be congenial for enhancing<br />

, the, herbage accumulation.<br />

areas.<br />

(N P. Shukla <strong>and</strong> Menhi Lal)<br />

1. Effect of phasic excess moisture conditions <strong>and</strong> nitrogen nutrition on forage yield of<br />

teosinte.<br />

The field investigation was conducted in the second year with a view to studying the<br />

response of teosinte to phasic excess moisture regimes during three growth phases ,15-30,<br />

( 82


30-45 <strong>and</strong> 45-60 days after sowing) <strong>and</strong> two levels of nitrogen (60 <strong>and</strong> 120 kg/ha) in R:.B.D.<br />

with three replications. ,<br />

The moisture treatments did not bring significant differences in forage production.<br />

..1owever, the highest green (393.1 qjha) <strong>and</strong> dry matter (110.1 qjha) yields were obtained<br />

when crop experienced well drained condition during early stage from 150-30 days after<br />

seeding <strong>and</strong> excess moisture regime thereafter. This' was closely followed by the trtatment<br />

involving well drainfed-excess moisture-well drained cycle during 15-30, 30-45 <strong>and</strong> 45-60<br />

davs of growth respectively indicating that there was no adverse effect of saturated soil condition<br />

if imposed beyond 30 days of crop growth. The crop suffered most when excess<br />

moisture was imposed during 15-30 days stage.<br />

Application of 120'kg Njha produced significantly higher green ,(393.3 qjha) <strong>and</strong> dry<br />

matter (109.7 qjha) as compared to 60 kg Njha (327.1 q green <strong>and</strong> 86.9 q d. m.jha) suggesting<br />

the need of higher dose of nitrogen for higher forage production under diverse moisture<br />

regimes.<br />

4.3 Evalution of different irrigation methods <strong>and</strong> soil management techniques for<br />

efficient water use.<br />

(N. P. Shukla <strong>and</strong> Menhi<br />

Lal)<br />

1. Performance .of forage bajra in relation to moisture. regimes, nitrogen fertility <strong>and</strong><br />

plant denstiy<br />

This was first year of the investigation. The experiment with three levels each of<br />

moisture regimes (25, 50 <strong>and</strong> 75% A~M), fertilizer nitrogen (30, 60 <strong>and</strong> 90 kg Njha) <strong>and</strong><br />

plant density (10,15 <strong>and</strong> 20 kg seedjha) was conducted in 3 3 factorial confounding with a<br />

view i:O studying the variation in crop water use as influenced bv cultural <strong>and</strong> fertilizer management<br />

practices.<br />

The increasing levels of soil moisture' SIgnificantly increased the forage production with<br />

the result that the highest.green (547.5 q/ha) <strong>and</strong> dry matter (170.6 qjha) yields were obtained<br />

with 75% ASM <strong>and</strong> the 10Nest with 25% ASM (305.6 q green <strong>and</strong> 91.9 q d.m.jha). Increasing<br />

dos of fertilizer nitrogen from 30 to 90 kg N jha progressively increased the green matter<br />

production <strong>and</strong> dry matter accumulation. However, 90 <strong>and</strong> 60 kg Njha were at par between<br />

( 83 )


themselves but significantly superior to 30 kg N/ha. Increasing the seed rate from 10 to 15<br />

kg/ha caused significant variation in forage yield <strong>and</strong> the highest green (477,8 q/ha) <strong>and</strong> dry<br />

matter (148.7 q/ha) yields recorded with 15 kg seedjha. Further increase in the the seed rate<br />

to 20 kg/ha did not improve the production <strong>and</strong> rather slightly depressed the yield. Therefore<br />

bajra may be seeded at 15 kg/ha <strong>and</strong> fertilized with 90 kg N Iha. The summer sown crop needs<br />

to be irrigated at 75% ASM for increased green <strong>and</strong> dry matter production.<br />

2. Effect of soil moisture regimes <strong>and</strong> phosphate fertility on the productivity of some<br />

forage legumes.<br />

The field experiment was conducted in order to study the productivity <strong>and</strong> response of<br />

3 legumes tBhtlore, Vicia <strong>and</strong> SU8un) to 3 levels each of moisture regimes (25, 50 <strong>and</strong> 75%<br />

ASM) <strong>and</strong> phosphate fertility (0, 30 <strong>and</strong> 60 kg P 205/ha) in 3 3 factorial for the first year.'<br />

The forage lei.urnes differed significa'itly in their production <strong>and</strong> may be rated as Susun<br />

> Vida> Bhilore on the basis of herbage accumutalion, The increasing moisture regime from<br />

25 to 75% ASM increased the forage yield but the differences were not statistically significant.<br />

Increasing doses of phosphate increased the productivity of legume. However, the differences<br />

betwen 0 <strong>and</strong> 30 kg P20s/ha did not reach the level of significance whereas 60 kg P20s/ha<br />

proved significantly superior to 0 <strong>and</strong> 30 kg P20s/ha.<br />

Therefore, among the legumes evaluated, Susun holds the promise of high forage<br />

productivity. Application of phosphate at 60 kg P20s/ha <strong>and</strong> irrigation 75% ASM have been<br />

found to enhance herbage accumulation in these species.<br />

4.4 Investigation on quality of irrigation water in relation to forage crops.<br />

(Menhi Lal <strong>and</strong> N. P. Shukla)<br />

During rabi 1983-84, the irrigative values of saline water, sewage <strong>and</strong> cattleshcd wash<br />

was evaluated against canal water on three species each of legumes (berseem, lucerne <strong>and</strong><br />

metha) <strong>and</strong> cereals (oat, barley <strong>and</strong> triticale) under green house conditions.<br />

On the basis of green <strong>and</strong> dry matter accumulation, the order of crop<br />

be mentioned as :<br />

productivity may<br />

Berseerri> lucerne> metha among legumes <strong>and</strong> Oat> barley> triticale among cereals.<br />

The [rrigative values of different types of water may be rated as :<br />

Sewage> catrleshed wash> c.inal water> saline water.<br />

( 84 )


Further, sewage, cettleshed wash <strong>and</strong> saline waters showed good irrigative values for<br />

berseem, lucerne <strong>and</strong> metha, respectively. The response of oat was better with cattleshed wash<br />

while that of barley a~d triticale with sewage irrigation:<br />

AG.5 EVALUATION OF FORAGE AND PASTURE MODELS.<br />

5.1 Modelling of forage farming systems with ideotype selection, crop gemoetry <strong>and</strong><br />

defoliationjclipping technology with special reference to forage crop;;.<br />

(R. K. P<strong>and</strong>ey <strong>and</strong> Fateh Singh)<br />

1. Comparability of lucerne genotypes with oat-3021 in their promising systems of mixed<br />

cropping at different levels of nitrogen application,<br />

This was the second year of the experiment. The treatments consisted of three lucerne<br />

strains (<strong>IGFRI</strong>-244, And<strong>and</strong>-2 <strong>and</strong> L. L. composite) <strong>and</strong> two levels of nitrogen application<br />

(60 kg <strong>and</strong> 60+30 kg Njha). The basal application of 60 kg N was followed by 30 kg N as<br />

top dressing as per the treatment. Treatments were employed in three time replicated r<strong>and</strong>omiscd<br />

block design on medium textured soil. Lucerne' was sown by broadcast at IS kg seed/ha<br />

<strong>and</strong> was immediately followed by oat at 50 em apart rows (50 kg seedsjha), Oat crop was cut<br />

twice (72 days stage <strong>and</strong> 50 per cent flowering). The initial cut of lucerne was taken at 87 days<br />

crop stage <strong>and</strong> subsequent cut after the final harvest of oat.<br />

In dry matter production of mixed fodder.tthe treatment effects were not significantly<br />

marked. However, the maximum fodder yield of 146.3 qjha was recorded when oat combined<br />

with lucerne (An<strong>and</strong>-2) at 60+30 kg N jha. This fodder yield also incorporated the highest<br />

component of legume (33.1 qjha.) Lucerne genotypes as well as nitrogen levels were found to<br />

be statisticaIly not significant in mixed fodder production (Oat-l-Iucerne).<br />

2. Forage production potential of energy rich system of senji+turnip in relation to<br />

seeding dates'<br />

The promising cropping system of scnji +- turnip along with their pure culture crops<br />

were evaluated. Crops of these systems were sown on three different dates (second week of<br />

October, last week of OCtober <strong>and</strong> second week of November. Broadcast senji (30 kg seed/ha)<br />

was superimposed with 50 em apart row crop of turnip (2.5 kg seedjha). PUle crops of both<br />

( 85 )


senji <strong>and</strong> turnip were maintained at 25 em row spacing. Trese nine crop combinations were<br />

tried in r<strong>and</strong>omised block design with three replicates on medium textured soil,<br />

Mixed cropping of senji <strong>and</strong> turnip appeared to be promising system for the dry<br />

matter production. The system yielded SUbstantially higher over the individual crop <strong>and</strong><br />

mean yield of both the crops in pure culture. In mixture, turnip produced 33.4 q/ha, additional<br />

biomass without jeopardising the output of companion crop (69.5 q/ha) as compared<br />

to its pure culture control (70.8 qjha). However, the maximum mixed dry matter yield of<br />

115.2 q/ha was recorded when crops of the system were sown in the last week of October.<br />

Turnip crop was taken out much earlier than senji which provided open space for the subsequent<br />

growth of leftover crop.<br />

3. Selection of wheat ideotypes for supplementary grain production with berseem sown on<br />

different dates.<br />

The experiment was repeated during the year on medium textured soil, The main crop<br />

of berseem sown on two different dates (second fortnight of October <strong>and</strong> first fortnight of<br />

November) was introduced with four strains of wheat (Sonalika, H. J. 784, H. D. 20,09 <strong>and</strong><br />

U. P. 3613) grown in the area. These eight combinations alongwith two treatments of pure<br />

berseem (one for each data of sowing) were evaluated in r<strong>and</strong>omised block design with three<br />

replicatles. Wheat at 50 kg seed/ha was so vn in 22 day established crop of berseem,<br />

All the four wheat genotypes appeared to pe '1t par in grain p-o.luction as the differences<br />

between them were found to be statistically not significant. None of the wheat strain<br />

reduced fodder yield of berseem significantly in comparision to pure cnlture control (53.1<br />

g/~a, dry matter), However, wheat U. P. 368 mixed with berseem showed maximum yield<br />

(21.7 q/ha). This treatment did not cause much reduction. in fodder production of berscem.<br />

4. Selection of barley ideotype for mixed cropping with mustardtmder variable crop<br />

geometry system.<br />

This was the second year when three barley genotypes (Ratna, karan <strong>and</strong> Jyoti) were<br />

evaluated in combination with mustard in the ratio of 2:2 <strong>and</strong> 4:4 rows. For comparison,<br />

their monoculture crops were also maintained. The spacing between the rows was 25 em. In<br />

all, ten treatments were studied in r<strong>and</strong>ornised block design with three replications.<br />

( 86 )


In almost all the combinations, the dry matter yield of mixed fodder showed an increasing<br />

trend over the meal} yield of barley <strong>and</strong> mustard in, pure culture. However, barley,<br />

karan mixed with mustard brought the maximum increase of 23.6 (2:2 rows) <strong>and</strong> 28'5 (4:4<br />

rows) percent over the mean of pure cultures. This combination was. at par with barley,<br />

Jyoti-l-rnustard in case of 2:2 row system. The former mixture, however, with 4:4 row<br />

arrangement, yielded maximum mixed (dry matter) of 129 qjha <strong>and</strong> incorporated the highest<br />

component of mustard (49.2 qjh) when compared with other crop combinations. There<br />

was not much variation in the row arrangements.<br />

5. System analysis of Deenanath grass with the genotypes of cowpeas for improved quality<br />

biomass production.<br />

Four fodder strains of cowpea (HFC 42-1, Russian giant. <strong>IGFRI</strong>-450 <strong>and</strong> NP-3)<br />

were evaluated in association with Deenanath.grass under two systems of their mixing dine<br />

sowing of grass with broadcast cowpea <strong>and</strong>. sowing of grass <strong>and</strong> cowp~a.in alternate paired<br />

rows). A treatment of pure grass crop was also included in the study. In mixed cropping,<br />

the cowpea crop was introduced at half seed rate (20 kgjha). The line sown crops were<br />

maintained at 25 em row spacing These nine treatments were thus, tried in r<strong>and</strong>ornisedblock<br />

design, replicated thrice.<br />

In both the systems of broadcasting as well as line sowing cowpea, NP-3 associated<br />

with Deenanath grass was found to be encouraging for mixed fodder production. These two<br />

treatm-nts did not reduce the dry matter yield significantly in comparison to monoculture<br />

yield of grass (84.6 qjha). Amongst the crop mixtures, this promising genotype of cowpea<br />

recorded a maximum mixed dry matter yield of 81.4 q/ha in broadcast' sowing. The fodder<br />

yield of this cropping system also included a highest component of legume (30.0 qjh::1 The<br />

same system replaced with Russian giant was next in order both from total yield <strong>and</strong> legume<br />

contribution. points of view but its yield level was lower than pure grass. Cowpea crop was<br />

harvested at 55 days growth stage in this study.<br />

6. System analysis of rnultiproportional blending of cereals <strong>and</strong> legumes for quality<br />

fodder prcduction.<br />

, ., \~<br />

,J. ~ 1f '<br />

In this experiment, fodder sorghum M. P. Chari was blended with the promising"<br />

forages in broadcast sowing. The. objective was tq synthesise a sorghum based, system of<br />

corrp.tible crops for quality fodder. Eight system viz: [I)'Sorghum' (M. P. Chari);<br />

87 )


{21 Treatment 1+bajra (Rajko), [3] Treatment 2+maize (African tall); [4] Treatment 3<br />

+teosinte, [51 Treatment 4+cowpea (HFC 42-1), [6] Treatment 5+guar (<strong>IGFRI</strong>-212),<br />

[7] Treatment 6+sesbania (annual), [8] Treatment 7+Sunhemp (exotic) were evaluated<br />

alongwith 25 em apart row crop of M. P. Chari. Each crop of the system was mixed with<br />

equal proporation of seeds. These nine treatments were employed in r<strong>and</strong>omised block<br />

design, replicated thrice.<br />

The broadcast sorghum (M. P. Chari) out yielded its line sown crop. Amongst the<br />

blending systems, M. P. Chari+bajra+maize+teosinte+cowpea+guar produced maximum<br />

dry matter yield of 111.9 qJha This herbage material was composed of different forage<br />

cereals as well as legume component. M. P. Chari contributed highest to the mixed fodder<br />

<strong>and</strong> was followed by other components in an order of bajra, maize, teosinte <strong>and</strong> cowpea.<br />

Guar, sesbania <strong>and</strong> sunhernp did not survive in any of the systems.<br />

7. Selection of ideotypes for mixed cropping of forage cereals <strong>and</strong> legumes.<br />

This was the first year of the study. Earlier, M. P. Chari+annual sesbania-l-cowpea<br />

(HFC 42-1) was worked out as an effective mixed cropping system. This set of three crops<br />

included one line of each at 25 em spacing grown in an alternate descending <strong>and</strong> ascending<br />

order of their heights. In this experiment. this system was differentiated substituting the<br />

former crop of M. P. Chari by sorghum (PC-6, Pioneer), bajra (Rajko), maize (African<br />

tall) <strong>and</strong> teosinte. These six crop mixtures were further differentiated substituting cowpea<br />

by sunhernp (exotic) in each case. The objective was to select the ideotypes for improved<br />

fodder production in the system. These twelve crop combinations were tried in r<strong>and</strong>omised<br />

block design replicated three times,<br />

Sorghum (PC-6)+annual sesbania-l-cowpea (HFC-42-1) yielded highest mixed fodder<br />

of 101'2 qJha including 18.2 qJha legume component (Sesbania-l-cowpea). This was composed<br />

of 82.0 percent cereal, 11.5 percent sesbania <strong>and</strong> 6.6 percent cowpea' Africantall maize<br />

-l-sesbania-l-cowpea provided maximum proportion of legume cowponent of of 26 qJha but<br />

the mixed fodder yield under this treatment was not so high as in case of above mentioned<br />

system Owing to the poor plant st<strong>and</strong>, the sunhernp contribution was not included in the<br />

mixed dry fodder yield.<br />

8. Evaluation of cereal-l-Iegume systems in the alternate strips of 4:4 rows for quality in<br />

the fodder production.<br />

The experiment commenced during the year <strong>and</strong> mixed cropping 'system of bajra<br />

( 88 ')


(Rajko) -l-cowpea (HFC 42-1) was evaluated substituting its former crop by five differnt forage<br />

cereals, viz, bajra (giant), sorghum (M.P. Chari), sorghum (Pioneer), maize (African tall)<br />

<strong>and</strong> teosinte. These six combinations with cowpea were further differentiated substituting the<br />

latter c 'op by sunhemp (exotic strain) in each case. These twelve treatment combina ions were<br />

tried in r<strong>and</strong>omized block design with three replications.<br />

None of the treatment combinations superseded the cropping system of bajra (Rajko)<br />

-l-Cowpea (HFC 42-1) in total dry fodder yield (cereal-l-Iegume) This system was statistically<br />

at par with the combination where bara crop (Rajko) was substituted by M. P. Chari' Since<br />

M. P. Chari -l-cowpea included the maximum proporation of legume (22 q{ha) in the mixed<br />

dry fodder yield of 103.2 q{ha, appeared to be more promising one. Sunhernp contributed<br />

less than cowpea in fodder production during the season.<br />

~<br />

Studies on intensive forage production system under continued tree cropping.<br />

The experiment was repeated with slight me dification, Setaria sphacelate was not<br />

included. The pure planting treatments comprised Leucaena, hybrid napier <strong>and</strong> guinea grass,<br />

<strong>and</strong> two intercropping treatmen ts were Leucaena-s-hybrid napier <strong>and</strong> Leucaena+guinea grass. I<br />

The trial was conducted in r<strong>and</strong>omised block design with 4 replications. The planting technique<br />

<strong>and</strong> other details were same as reported last year.<br />

runde report.<br />

In alI five cuts were taken during the period<br />

The results indicated that combination of Lcucaena <strong>and</strong> hybrid napier '<strong>IGFRI</strong>-3' gave<br />

the maximum green fodder yield (2031 q{ha). This legume grass combination was significantly<br />

superior to rest of the treatments tried in the investigation.<br />

2. Lleotype selection under intensive forage farming system with special reference to<br />

continued tree cropping'<br />

This was tle second year of the investigation. In all 3 cuts from leucaena <strong>and</strong> five-cuts<br />

from hybrid napier were taken during the period under report. The green fodder yield (pooled<br />

89 )


asis) under various treatments was statistically analysed <strong>and</strong> intercropping of Lcucaena-r<br />

Hybrid napier '<strong>IGFRI</strong>-3:gave the highest green fodder yield (2783 q/ha) which was significantly<br />

higher over rest of the treatments' The other treatments in order were Leueaena+HybriJ<br />

lapier'<strong>IGFRI</strong>-60' <strong>and</strong> Leuceana-rNB-21.<br />

3. Intercroppng studies' with sorghum ideorypes under intensive forage farming system<br />

with special reference to continued forage tree cropping.<br />

Treatments comprised monocropping of Leucaena <strong>and</strong> the three sorghum ideotypes<br />

(S. bicolor, S. almum <strong>and</strong> S. Sudanensey <strong>and</strong> intercropping of these sorghum ideotypes with<br />

Leucaena, In all there were seven treatments laid out in raridomised block design with three<br />

replications.' During the winter season sorghum was succeeded by a crop of Brassica for<br />

fodder both under sole as well as intercropping treatments, Leucacna, Sorghum <strong>and</strong> Brassica<br />

were sown on March 2, March 23 <strong>and</strong> November 15, respectively. Basal fertilization included<br />

30 kg N +30 kg P20s/ha for Leucaena <strong>and</strong> Sorghum<strong>and</strong> 30 kg N /ha for Brassica. Top<br />

dressing of 30 kg N/ha was made to sorghum on April 20 <strong>and</strong> after first, second <strong>and</strong> third<br />

cuts <strong>and</strong> to the Brassica on December 15. For green fodder yield four cuts were taken from<br />

Leueaena <strong>and</strong> sorghum <strong>and</strong> one cut from Brassica, during the period under report,<br />

Treatment Leucaenc-l-S', Sudanznse-Brassica gave maximum green fodder yield (1327<br />

q/ha). Next best treatment was Leucaena-rS: bicolor-Brassica followed by S. sudanense­<br />

Brassica. Pure Leuceana gave the lowest yield (561 q/ha). Among intercropping treatment<br />

Leucaena performed best with S. bicolor. Among sorghum ideotypes, maximum yield was<br />

achieved with S. sudanense under intercropping treatments. Thus,


Sorghum intercropped with Snevri gave significantly higher green fodder yield (529<br />

qjha) as compared to the remaining treatments. Sorghum component in intercropping racorded<br />

higher green fodder yield (452 qjha) as compared to pure crop of sorghum (382 qjha),<br />

though Shevri gave the least (77 qjha) green fodder yield in association with sorghum as<br />

compared to maize (196 qjha) <strong>and</strong> teosinte (193 qjha).<br />

Maze-l-shevri <strong>and</strong> teosinte-j-shevri gave green fodder yields of the order of 353 qfha<br />

<strong>and</strong> 4.53 l{jha against 260 <strong>and</strong> 346 qjha obtained under sale crop of maize <strong>and</strong> teosinte,<br />

respectively. Similar trend was also observed for dry-matter yield:<br />

,<br />

5. Selection of a suitable cereal perennial fodder crop under continued tree cropping.<br />

This was the first year of the trial. Treatments comprised pure planting of cereal perennial<br />

fodder crops (Hybrid napier, guinea grass <strong>and</strong> N<strong>and</strong>i grass) <strong>and</strong> Sesbania gr<strong>and</strong>iilora <strong>and</strong><br />

intercropping treatments (tree-l-hybrid napier guinea grassjN<strong>and</strong>i grass). In all there were<br />

seven treatments laid out in r<strong>and</strong>ornised block design with three replicates.<br />

Two cuts Were recorded from grass component during the period under report. Pure<br />

planting of hybrid napier registered maximum green fodder (l076 qjha) <strong>and</strong> dry matter<br />

(269'9 qjha) yield, Hybrid napier, guinea grass <strong>and</strong> Setaria recorded 0.67 kg, 0.37 kg <strong>and</strong><br />

0.26 kg under sale cropping <strong>and</strong> 0.60 kg, 0.48 kg <strong>and</strong> 0.24 kg dry matter per plant in association<br />

with the tree component, respectively.<br />

1. Cross vs, parallel intercropping of safflower in rabi forages (berseem <strong>and</strong> senji).<br />

There were seven treatmentsTTj : Safflower two rows followed by berseem two rows<br />

each at 30 em row spacing; T 2 : Safflower two rows followed by 'senji two rows at 30 ern. row<br />

spacing; T 3 : Berseem at 30 ern row spacl11g in full plot crossed sown with safflower at 50 em<br />

row spacing; T 4 : senji at 30 cm row spacing in full plot crossed sown with safflower at 50 em<br />

row spacing; T5: Safflower (pure); T G : Berseem (pure): <strong>and</strong> T 7 : Senji (pure) .each at 30 em<br />

row spacing) repeated thrice in RBp.<br />

( 91 )


Treatment wise there were significant differences in total forage yields. The combined forage<br />

yields under cross planting system was highest <strong>and</strong> proved to be significantly superior yielding<br />

followed by berseem <strong>and</strong> safflower when sown under parallel planting system (310.83 qjha),<br />

The combined forage yield of senji <strong>and</strong> safflower under cross planting system (286.38 q!ha)<br />

was significantly better than their production under parallel planting system (237.77 qjha).<br />

There was no significant difference in the pure forage yields of safflower (292.77 qjha) <strong>and</strong><br />

safflower plus senji (286.38 q!ha) Sown under cross planting system. Also there was no significantdifference<br />

in the yield levels of safflower (pure) (292.77 q jha) <strong>and</strong> safflower plus senji<br />

under cross plinting (286.38 q!ha) or safflower plus berseern (310.83 q/ha) <strong>and</strong> safflower pure<br />

(292.77 qjha),<br />

The bare soil respiration was 2.266 mg CO 2 in 24 hours (day <strong>and</strong> night) period. The<br />

cropped area had more respiration than the uncropped area (average value being around 13 mg<br />

CO 2!24 hrs. Also the crop respiration gradually decreased from top to the middle height of<br />

the crop canopy, top average being more than 4 mg CO 2/24 hI'S. <strong>and</strong> around 2.75 mg CO~d24<br />

hrs on the middle height of the crop cJ.nopy. But it SUddenly rose m lny folds.on bottom of<br />

the crop i.e. on soil surface approaching to an average v.ilue of 13.8mg CO 2!24hrs. This might<br />

be on account of root respiration. The legume crops (berseern <strong>and</strong> senjis had more respiration<br />

rate than safflower either sown pure or in mixed culture. The respiration rate on ground of<br />

senji plots, mono as well as intercrop, was higher than bersecrn mono or intercrop.<br />

2. Performance of cross vs parallel planting of f'oraacs under pigeon pea based forage<br />

intercropping systems.<br />

There were seven treatme 1tSas (1) pigeon pel (pure) lines at 100 em row spacings, (2)<br />

pigeon pea lines at 100 em row spacing intercropped with cowpea at 30 em ro v spacing, (3)<br />

pigeon pea lines at 100 em row spacing intercropped with teosinte at 30 cm row spacing, (4)<br />

pijeon pea lrnes at 100 em row spacing, cross planted with cowpea at 30 em row spacing, (5)<br />

pigeon pea at 100 em row spacing cross planted with teosinte at 30cm row spacing, (6) teosinte<br />

(pure) at 30 em row spacing <strong>and</strong> (7) cowpea (pure) at 30 ern row spacing. The experirnant<br />

was laid out in RBD with three replications,<br />

Pigeon pea was not accounted for forage yield. There was a signjfican,t dilT\:rence in the<br />

green forage yields of various treatnents. The highest green forage. was recorded with teosinte<br />

(476.6 q/ha) when sown as mono Ciap followed by teosinte planted with pigeonpea (469.9<br />

q!ha) under paralled planting system. The lowest yield recorded was 159.9,q!ha for cowpea<br />

sown with pigeonpea under parallel planting system.<br />

( 92 )


Cross planting system for cowpea with pigeon pea gave significantly better yield (247.7<br />

q!ha) under parallel planting system (159.9 q!ha). However, in case of teosinte with pigeon<br />

pea, sown in either system, the yields were of same order with no significant. difference. There<br />

was no significant difference in the yield of cowpea sown either as pure crop (265.5 qjha) or<br />

with pigeon pea under cross planting system (247.7 q/ha;. Thus, in cross planting system, the<br />

yield of pigeon pea becomes an additional gain.<br />

3. Pigeon pea based forage intercropping systems under replacement series with cowpea,<br />

M, P. Chari <strong>and</strong> teosinte for maximum forage production,<br />

This experiment comprised five treatrnenrs (2) cowpea one line followed by M. P.<br />

Chari one line followed by pigeon pea one line each at 30 em row to row spacing, (2) cowpea<br />

one line followed by teosinte one line followed by pigeon pea one line cach at 30 em row to<br />

row spacing, (3) cowpea two li~es followed by M. P. Chari 2 lines followed by pigeon pea<br />

one line each at 30 cm row to row specings, (4) cowpea 2 lines followed by teosinte 2 lines<br />

followed by pigeon pea one line cach at 30 em row to row spacing <strong>and</strong> (5) M. P. Chari one<br />

live followed pigeon pea one line followed by teosinte one line vcach at 30 ern row to row<br />

spacings. Experiment was laid out in RBD replicated thrice.<br />

The green fodder yields were pooled treatmentwise, 'pigeon pea was not accounted<br />

for fodder purpose. The mean green fodder yield was highest (247.7 q/ha) in cowpea (1)<br />

M. P. Chari (I) Pigeon pea (1) series followed QY cowpea (2) M. r. Ch~ri (2) Pigeon pea<br />

(1) 234.4 q!ha) <strong>and</strong> cowpea (2) teosinte (2) Pigeon pea (1) (232.9 q!ha) but the differences<br />

not significant. The series namely, M. P. Chari (1) Pigeon pea (1) teosinte (1) yielding<br />

195.5 qjha <strong>and</strong> cowpea (2) M. P, Chari (2) Pigeon pea (1) yielding 167.7 q!ha were<br />

significantly inferior to other three treatments.<br />

. .<br />

The higher population density of M. P. Chari tends ~O hamper the yields of companion<br />

crop, Among the 'better yielding series, cowpea (2) teosinte (2) pigeon pea (1) is' supposed<br />

'to be ~utritionall~<br />

much better than the others due to high row-ratios of legume component.<br />

2. Compatibility of intercropping with Cenchrus ciliaris,<br />

In this experiment eight intercrops were introduced in the established,Cenchrus cillaris,<br />

viz; Cowpea (HFC-42-1), guar'(<strong>IGFRI</strong>-212), Dhainch (annual), M. P. Chari, maize (African<br />

tal1), bajra (An<strong>and</strong>, Rajko) <strong>and</strong> sorghum (PC-6)' For comparison, pure Cenchrus ciliaris<br />

was also maintained. These nine treatment combinalions'were tried in" r<strong>and</strong>ornised block<br />

design' with three replications. The plot size was 4 X 3 cm (net), Two cuts of Cenchrus<br />

were taken in the Ist week of August <strong>and</strong> Jast week of September.<br />

The yield of Cenchrus ciliaris was not reduced by the intercrops, However, it was.<br />

maximum in pure grass plots (40.7 qjha) fol1owed by Cenchrus+cowpea. Among, intercrops<br />

sesbania produced maximum fodder (20 q/ha d. m.), However, the differences 'were found<br />

statistically not significant. The maximum dry matter pi oduction (grass-l-Intercrops) was<br />

recorded in the treatment Cenchrus-s- Dhaincha, It is conluded from the experiment that<br />

1. Sugarcane as cash crop.<br />

Treatments comprised pure planting of sugarcane <strong>and</strong> Luccaena as well as their intercropping<br />

with Leucaena kept uncut <strong>and</strong> cut at 50 ern, 100 em, 150 cm <strong>and</strong> 200 ern from the<br />

ground surface. In all, there were Seven treatments. Leucaena <strong>and</strong> sugarcane were planted<br />

on August 14, 1983 <strong>and</strong> February 16, <strong>1984</strong> respectveiy, The cutting in Leucaena was done<br />

on June 28, <strong>1984</strong>, Fertilizer schedules of 20 N +30 P:105jha (basal) to Leucacna <strong>and</strong> 120 N<br />

(basaljsplit)+30 P205jha (basal) to sugarcane. Sugarcane was harvested on November 15,<br />

<strong>1984</strong>. <strong>Fodder</strong> (leaf) <strong>and</strong> fuel (stem) yields were recorded in Leucaena on December 15,<br />

<strong>1984</strong>.<br />

Maximum sugarcane yield <strong>and</strong> fodder jfuel production in Leucaena was registered when<br />

these crops were under solid planting. Among intercropping treatments, sugarcane gave best<br />

performance with Leuceana cut at 50 em height, whereas maximum fodder jfuel in Leucaena<br />

was registered with uncut treatment. Thus, this study indicated that Leucaena was not<br />

ideal forage plant to be associated with sugarcane.<br />

DIVISION OF SOil SCIEN CE<br />

SS-I: SOIL STUDIES UNDER INTENSIVE FODDER PRODUCTION<br />

1.1 Soil fertility <strong>and</strong> plan t nutrition studies,<br />

(S. B. Tripathi <strong>and</strong> C. R. Hazra)<br />

1. Effect of levels <strong>and</strong> source-s of P in forage production of Melilotus<br />

Field experiment was taken 'up to work out the affect of P sources (chemical-P, organic<br />

-P <strong>and</strong> their combination) at different levels of application on forage yield of senji <strong>and</strong><br />

nutrient status of soil. The results are as follows:<br />

(i)<br />

Forage yield<br />

The forage yield increased upto 120 kg P205/ha through FYM over control, whereas<br />

similar response was obtained with 40 kg P20sjha through single superphosphate. Combined<br />

application of 80 kg P20sjha through organic <strong>and</strong> inorganic sources (1:1) increased yield<br />

signficantly as compared its application either through SSP or FYM. The highest forage<br />

production (364.5 q green <strong>and</strong> 80A,q drymatterjha was obtained when 120 kg P20s/ha was<br />

applied half as SSP <strong>and</strong> hals a5 FyM. ,<br />

(ii)<br />

P uptake<br />

. P application increased nutrient uptake as compared to control treatment. Increasing<br />

levals ofP with all the sources incereased N uptake. The performance of SSP was significantly<br />

superior to FYM in giving higher P uptake at all levels of its application, Combined use of<br />

FYM <strong>and</strong> SSP sn 1:1 ratio to supply 120 kg P 20s/ha significantly increased' nutrient<br />

uptake.<br />

(iii)<br />

Soil fertility<br />

Ec end organic carbon values were generally higher with increased P application.<br />

Available N<strong>and</strong> P contents in soil at harvest increased with an increase in P levels. FYM had<br />

higher beneficial effect in influencing available N<strong>and</strong> P contents than SSP or their combination,<br />

( 97 )


2. Effect of N fertilization on oats in association with legumes <strong>and</strong> non-legume<br />

inter crops.<br />

The field experiment was laid out to know the contribution ot legumes <strong>and</strong> non-legumes<br />

components \.0 forage production <strong>and</strong> soil fertility under different N levels (25, 50, 75 <strong>and</strong><br />

100 per cent of recommended dose of 120 kg N/ha to oat crop). Legumes (pea, senji a-id<br />

lucerne) <strong>and</strong> non-legumes (safflower <strong>and</strong> chinese cabbage) were taken as inter crops in<br />

oats.<br />

The results indicated that green <strong>and</strong> dry fodder yield of oat as well as inter crops<br />

increased with increasing levels of N. However, significant response to N was obtained at 75%<br />

N level with oat or oat-l-non-Iegurne <strong>and</strong> 50% with oat-l-Iegume mixtures. Legumes <strong>and</strong><br />

non-legumes as inter crops with oat responded significantly to nitrogen application upto 100%<br />

except lucerne which sowed significant response at 75% N level. The forage yield of cat<br />

reduced with various crop mixtures as compared to pure oat & maximum reduction was noted<br />

with oat-l-chinese cabbage. Oat-l-Iucerne was found to produce maximum yield. On the basis<br />

of total relative forage yield under different cropping systems, the response to N were higher<br />

with oat-l-legume than oat-l-nou-Iegumes.<br />

3. Phosphte availability <strong>and</strong> fixation under .ntercropping system of napier+legume.<br />

Field experiment was laid out under intercropping system of napier-l- legumes with P<br />

fertilization to find out out the effect of P levels on forage production in different seasons, i. e.<br />

winter, summer <strong>and</strong> rainy seasons. For this purpose P was applied in all the three seasons, two<br />

seasons <strong>and</strong> only one season. Forage legumes berseem (rabi) co .pea (summer) <strong>and</strong><br />

cowpea (khari f ) were grown with napier maintained on perennial basis.<br />

It was observed that the application of P increased forage yields of legumes <strong>and</strong> napier<br />

as compared to control <strong>and</strong> maximum response was obtained with winter season applica ion<br />

followed by rainy season. Phosphorus showed least response in summer. Forage yield of napier<br />

+legume increased with increasing levels of P. The application of P both in winter <strong>and</strong><br />

summer showed higher response in increasing forage yield than its application in rainy <strong>and</strong><br />

winter season or summer rainy Seasons. However, the maximum forage production was recorded<br />

when P application was made @ 60 kg P 2 0 5/ha in all the three seasons.<br />

4. Effect of Mo <strong>and</strong> P application on forage production of berseern.<br />

Field experiment was carried out to how the effect of Mo <strong>and</strong> P application on<br />

98 )


forage production of berseem. Mo was applied through different methods (full basal,' full<br />

foliar <strong>and</strong> basal plus foliar) with various levels ot P (0, 50, 100 <strong>and</strong> 150 kg P 205/ha),<br />

1 he result indicated that the forage yield of berseern increased with increasing<br />

level of P <strong>and</strong> significant response was obtained upto 100 kg Pz05/ha, The yields with 100<br />

ard 150 kg P203!ha were, however. at par. The green <strong>and</strong> dry fodder. yield of berseem increased<br />

significantly with Mo application' as compared to control treatment. Application of<br />

Mo as full foliar increased forage yield significantly over either half or full soil applied Mo.<br />

The highest forage yield of berseern was recorded with ISO kg PzOs/ha in conjunction with<br />

1.5 kg Mo0 3/ha (foliar spray)" The uptake of P <strong>and</strong> Mo was also found to follow the trend<br />

of forage yields.<br />

5. Effect of N fertilization to oats on forage production <strong>and</strong> soil properites under different<br />

crop COVers.<br />

Field experirneat was conducted with graded doses of N (0, 10, 20, 40, 60 <strong>and</strong> 80 kg<br />

N Iha) to oats after Khari( crops of sunhemp, cowpea, guar <strong>and</strong> fallow for finding out the<br />

contribution of legmus towards forage production <strong>and</strong> soil fertility; The forage yield was<br />

increased with increased N application under all crop covers.. The crop of oat responded<br />

upto 60 kg N Iha under follow, sunhemp <strong>and</strong> guar upto 80 kglha under cowpea with respect<br />

to green forage yield. The data on dry forage yield, however, indicated that oat responded<br />

to 80 kg N/ha under follow, 60 kg N/ha under sunhemp/guar <strong>and</strong> 80 kg N/ha under cowpea<br />

The yield obtained under follow plot with 80 kg N/ha was achieved with 20 kg Njha under<br />

cowpea/sunhemp <strong>and</strong> with 40 kg Njha under guar. Oat under sunhernp <strong>and</strong> cowpea yielded<br />

100% <strong>and</strong> 74% more than under fallow. Similarly, the yields under guar without N fertilization<br />

was 29% more than unfertilized fallow.<br />

6, Effect of nitrogen fertilization on forage production <strong>and</strong> soil properties under. intercropping<br />

system of napier <strong>and</strong> legumes.<br />

The field experiment was undertaken to work out the contribution of legumes to the<br />

total biomass production <strong>and</strong> fertility status of soil under intercropping system of napier<br />

<strong>and</strong> legumes as compared to monocropping of napier with N application. Nitrogen at 0, 50,<br />

100 <strong>and</strong> 150% of recommended doses of 250 kg N Ihajyear to napier was applied to intercropping<br />

systems in various crop seasons. Forage legumes berseem, senji <strong>and</strong> pea in rabi <strong>and</strong><br />

cowpea, guar <strong>and</strong> sunnemp in summer <strong>and</strong> kharif were grown wLth hybrid napier.<br />

, .<br />

( 99 )


The result indicated that the application of nitrogen in gene raj increased forage yield<br />

of hybrid napier as legumes in all crop seasons. The maximum forage production was recorded<br />

in intercropping system of napier-l-berseem in rabi <strong>and</strong> napier-l-sunhemp in Kharif <strong>and</strong><br />

summer seasons. Forage production was found to be higher in Khartf season followed by<br />

summer. Legume yields were more during rabi than other seasons, Napier during rabi <strong>and</strong><br />

legumes during Kharif showed minimum productivity. The total forage yield of napier+ legumes<br />

in intercropping system increased by 121, 128, 115 <strong>and</strong> 112 percent at 0, 50, 100 <strong>and</strong><br />

150 percentof applied N over sole cropping of napier respectively. Hybrid napier yielded<br />

1098, 1234, 1450 a~d 1592 q/hajannum at corresponding levels of nitrogen nutrition.<br />

1.2 Studies on bacterial mediated N 2 fixation for increased productlvity in cultivated<br />

cereal <strong>and</strong> legume fodder crops.<br />

(M. R. Pahwa)<br />

1. Inoculation with varying cell population densities of Rhizobium.<br />

In a pot culture experiment using medium black soil, berseem seed inoculation was<br />

tried at five cell population densities (0, 2.5 x l 0 2 , 2.5 X 104, 2.5 X 106 <strong>and</strong> 2.5 x 10 8 cells/<br />

/ml).<br />

Maximum beneficial effect on nodulation, green <strong>and</strong> dry matter accumulation was observed<br />

with the inoculum containing 2.5x 10 6 cellsjrnl, However, significant differences were<br />

not obtained between 2.5 X 106 <strong>and</strong> 2.5 X 10 8 cells/ml.<br />

2. Interaction with plant nutrients.<br />

It<br />

Separate investigations were carried out on berseern, lucerne <strong>and</strong> pea in pot <strong>and</strong> microplot<br />

conditions with a view to find out the optimum level of Zn, Mo <strong>and</strong> Sunder rhizobial<br />

inoculated crops. The experimental soil Was red with a PH of 8.2.<br />

Out of the four levels of sulphur (0,10,20 <strong>and</strong> 30 kgjhat, 20 kg Sjha interacted significantly<br />

in stimulating nodulati on <strong>and</strong> increasing green <strong>and</strong> dry matter yields of berseem,<br />

Inoculation alone .gave an added benefit in terms ofgreen forage yield to the extent of 31%<br />

over uninoculated control in pea, Inoculation increased the effectiveness of symbiotic N 2 ­<br />

fixation by 40,6,(~ over 20 kg ZnS04/ha.<br />

100 )


Similarly significant increase in green <strong>and</strong> dry matter yields of lucerne was obtained<br />

with 20 kg ZnS04/ha inoculated treatment which also gave maximum nodulation (20/plant)<br />

at second cut.<br />

Application of 2 kg Mojha appeared to be optimum not only for enhancing nodulation<br />

reot length but also bringing about significant improvement in forage yield of<br />

lucerne.<br />

3. Rocx-pyrlte in lucerne-Rhizobium symbiotic system.<br />

The addition of appropriate dose of rock pyrite has been found to playa key role in<br />

bringing down the pH at a point where the microbial activities is stimulated. The experiment<br />

was conducted in pots filled with red soil (pH 8.2) consisting of five levels of rock-pyrite<br />

(), 2.5, 5.0, 10.0 <strong>and</strong> 15,0 t/ha) under inoculated <strong>and</strong> uninoculated series.<br />

Significant increase in total green <strong>and</strong> dry matter accumulation was obtained with<br />

inoculated 5 t/ha treatment. This also exhibited a positve influence on nodulation <strong>and</strong> root<br />

length first cutting.<br />

4. Residual effect of organic amendments cellulolytic fungi <strong>and</strong> Rhizobium inoculation on<br />

growth <strong>and</strong> fodder yield of oat following cowpea.<br />

The residual effect of three organic amendments (dried Sesbania aegyptiaca leaves,<br />

farm yard manure, <strong>and</strong> wheat straw) at 0 <strong>and</strong> 5 t(ha with four types of inoculation (control,<br />

Rhizobium, mixed culture of Chaet omium globosum-rAspergillus higher fungi <strong>and</strong> Rhizobium<br />

+composite fungi) was studied on forage oat grown after cowpea. Sesbania amended soil<br />

receiving Rhizobium <strong>and</strong> mixed fungi produced green <strong>and</strong> dry matter yields equivalent to that<br />

obtained with farm yard manure+ Rhizobium treated soil. Inoculation with Rhizobium+fungi<br />

contributed 18% more to forage yield of oat. Thus, the study revealed the benefits of microbial<br />

ino culation <strong>and</strong> organic amendments on the subsequent forage crop.<br />

5. Residual effect of wheat straw, cellulolytic fungi <strong>and</strong> rhizobial inoculation on growth<br />

<strong>and</strong> fodder yield of oat following cowpea (NP-3).<br />

The data indicated maximum stimulation in green (13.7 g/plant) <strong>and</strong> dry matter<br />

~ accumulation (3.4 g/plant) of oats under soil amended with wheat straw at 5 t/ha+<br />

Rhizobium.<br />

f, b··Response of maize-lucerne rotation to single <strong>and</strong> combined inoculation of homologous<br />

(tRhizobium, Azotobacter chroococcum <strong>and</strong> A. brasilense.<br />

Both the crops in the sequence were repeatedly inoculated with Rhizobium mellloti,<br />

AzotolJHcter chroococcum <strong>and</strong> A. brasilense either singly or in combination at the time of<br />

sowidg. Combined application of Rhi zobium-r Azot obccter <strong>and</strong> Rhizobium-vAzospirillum<br />

significantly increased forage yield with the result that the highest green matter was obtained<br />

with the association of Rhizobium-s-Azotobacter (28.8 g{plant). The associative effects of<br />

these cultures continued to exhibit increased nodulation upto second cutting.<br />

. The experiment also included fodder maize during kharit' <strong>1984</strong>. Surface sterilized maize<br />

seedJtVijay composite) were inoculated with single <strong>and</strong> mixed cultures of N 2 fixers. Significan1l'y<br />

higher green (27.9 g{plant) <strong>and</strong> dry maiter (6.0 g{plant) yields were recorded with<br />

mixe5dl~ultL\reof R. meliloti -s-Azospirillum +Azotobacter.<br />

7. JfJiEvaluation of efficacy of single <strong>and</strong> multi-strains culture of Azotobacter on oat <strong>and</strong><br />

Jo6orghutn.<br />

Separate studies wuh three strains of proven efficiency (A41, M4 <strong>and</strong> C2) were<br />

undertaken in pots filled with red soil of normal pH. Inoculation with two strains (A41 +C2)<br />

gave-superior performance in respect of forage yield of oat. On the other h<strong>and</strong>, the associative<br />

effect of M4+C2 produced the highest green matter yield of sorghum. These observations<br />

suggest that mixed culture of Azotobacter gives better results than in isolation.<br />

,1 J1<br />

8. m,,~esponse of forage oat to inoculation with mixed strains of Azotobacter <strong>and</strong> nitrogen<br />

lio{ertilization.<br />

~f.'~our levels of N (0, 40, 60 <strong>and</strong> 120 kg N jha) were tried in presence <strong>and</strong> absence of<br />

mixdaOdtrains of Azotobacter (M 4+C2 ) . The experiment conducted in microplots was<br />

termigJted after 115 days of sowing. The green forage yield (262.8 qjha) with inoculation was<br />

17.1% higher than that without nodulation (224.3 qjha). The combined treatment of40 kg<br />

N jha <strong>and</strong> inoculation produced comparable forage yield with 60 kg N jha. The results, thus,<br />

suggy~t!jl saving of about 20 kg N jha through the application of mixed strains without<br />

affecting the forage yield.<br />

9. Effect of inoculation with Azotobacter, Azospirlllum, root extract of hybrid napier<br />

. J'lB-6 <strong>and</strong> rhizosphere soil extract on forage yield of oat.<br />

The experiment was conducted to know the comparative benefits from N 4 - fixers as<br />

( 102 )


well as root <strong>and</strong> rhizospheric soil extract of hybrid napier. A 25~~ root <strong>and</strong> rhizospheric soil<br />

ext act was prepared. This was used in two forms, (i) cold <strong>and</strong> (ii) neated for 15 minutes <strong>and</strong><br />

then cooled. The combined application of rhizosphere soil extract <strong>and</strong> Azotobacter showed<br />

maximum stimulatory effect on green matter. Application of hybrid napier root extract on<br />

the seed in conjunction with Azotobacter inoculation also exhibiteu similar response on forage<br />

yield of oats.<br />

10. Response of oat <strong>and</strong> sen]! under intcrcropping system to inoculation with Azotobacter<br />

<strong>and</strong> Rhizo'iium.<br />

Si~nificantly higher green forage yield was obtained when senji <strong>and</strong> oat received inoculation<br />

of Rhizobium <strong>and</strong> Azotobacter respectively (353.3 q/ha). Uninoculated oat (243.3 qjha)<br />

<strong>and</strong> senji 210.0 q/ha) produced lower forage yields indicating that both the crop components<br />

111 in.ercropping system need ~o be inoculated with Nz-fixers for high forage production.<br />

11, Effect of nitrogen fertilization <strong>and</strong> inoculation with Azospirillum On growth <strong>and</strong> forage<br />

~ ield of teosinte.<br />

In microp lot experiment, four levels of N (0, 30, 45 <strong>and</strong> 90 kg/hal Were tested in<br />

presence <strong>and</strong> absence os Azospirillum culture. Initial Azospirillum count in soil was found<br />

10 be Ct.16 xl 04 cellsjg. Seeds of teosinte were inoculated by spinkling an aquoue solution<br />

cf a sticker (6 g of carboxymethyl cellulose in 500 ml of water) <strong>and</strong> sterilized farm yard<br />

manure (1: I) based powder inoculant containing live cells of the bacteria. The maximum<br />

green forage yield was obtained at 90 kg N /ha. Inoculation with Azospirillum registered on<br />

an average 10.6% increase in forage yield over un inoculated control. The efficacy of the<br />

culture was lower with nitrogen fer rilization. There was a saving of about 15 kg N/ha<br />

through the culture as green forage yields with 30 kg Njha-l-Inoculation <strong>and</strong> 45 kg N/ha<br />

were comparable. The rhizosphere Azospirillum count was the highest with 30 kg N /ha+<br />

inoculation (13.5 X 10 4 cells/g). The rhizospher/soil count ratio for inoculation was 60<br />

against merely 5 for uninoculation.<br />

12. Effect of inoculation with mixed culture of Azospirillum Azotobacter <strong>and</strong> N fertilization<br />

on growth <strong>and</strong> fodder yield of sorghum (M. P. Chari):<br />

A microplot experiment was conducted for a period of 70 days to assess the associative<br />

effect of mixed cultures in respect of forage productivity as well as saving of nitrogen<br />

Inoculation alone was observed to register about 25% higher green forage yield over uriinoculated<br />

control (183.3 q/ha). The inoculated 30 kg N/ha treatment recorded alost comparable<br />

103 )


green forage yield (254 qjha) to that of 45 kg Njha (252 qjha) indicating, thereby a<br />

net saving of 15 kg Njha. The graded levels of nitrogen however, showed continuous decrease<br />

ni the efficacy of the culture.<br />

13. Effect of leaf extract of Lcucaena leucocehala <strong>and</strong> rhizobial inoculation on nodulation,<br />

growth <strong>and</strong> forage yield of cowpea (NP-3).<br />

In a pot culture study the effect of five concentrations of dried Leucaena leaf extract<br />

(0,0.5, 2.5, 5.0 <strong>and</strong> 10%) was examined on c'.:)\vpea-Rhizobium symbiotic system. Dried<br />

leaves of Leucaena were ground extract was prepared in two forms, viz, cold (C) <strong>and</strong> autocJaved<br />

<strong>and</strong> then cooled (AC)~ The data showed inhibitory effect of leaf exract either cold<br />

or autoclaved cooled on nodulation, growth, green <strong>and</strong> drv matter yields. Inoculation alone,<br />

exhibited the highest green (95.0 gjplant) <strong>and</strong> dry' matter (12.9 gjplant) accumulation. It<br />

is postulated that the leaf extract might contain<br />

on the efficacy of rhizobia.<br />

toxic compounds causing deleterious effect<br />

1.3 Improving forage productivity <strong>and</strong> efficacy of indigenous rock phosphates through<br />

phosphate solubilizing micro -organisms.<br />

(M. R. Pahwa)<br />

1. Effect r f phosphate solubilizing microorganism <strong>and</strong> type of rock-phosphate on growth<br />

<strong>and</strong> fedder yield of Azotobacter inoculated oats <strong>and</strong> sorghum (M. P. chari).<br />

Separate studies were initiated with a view to find out the right combination of rock<br />

phosphate <strong>and</strong> micrco ganisms for augmenting the forage yield, Seeds were inoculated with<br />

suspension of Azotobacter culture. There were twenty treatment combinations involving five<br />

phospha e carriers (single super phosphate, Mussoorie, Luccadive, Udaipur <strong>and</strong> Vishakhapatnam<br />

rock phosphates) each at two levels (0 <strong>and</strong> 153 kg P20 5jha) with <strong>and</strong> without<br />

phosphate solubilizing organism. Udaipur rockphosphate in presence o~ Bacillus polymyxa<br />

H 6 significantly improved green (9.2 gjp!ant) <strong>and</strong> dry matter (24 gjplant) yields of oats.<br />

Phcsphobacterized seeds alone resulted in 33% higher green yield. The ncrease in green<br />

forage yield <strong>and</strong> dry matter accumulation may be due to increased efficiency of phosphate<br />

by the solubilizers. Therefore, the role of Azotobacter as a phosphate solubjiizer can not be<br />

r.iled out.<br />

Simi aIy, Vishakhapatnam rock phosphate Pseudomonas striata combination ranked first in<br />

improving plant height, green <strong>and</strong> dry matter yields of forage sorghum in red soil.<br />

1.4 Environmental analysis in different forage systems.<br />

(C. R. Hazra <strong>and</strong> Pradeep Behari)<br />

The present experiment on row d 'rections in pure <strong>and</strong> mixed st<strong>and</strong>s of oat was<br />

conducted during rabi 1983-84. The row directions were NE-SW, SE-NW, <strong>and</strong> N-S. The crop<br />

combinations were oat, oat-s-pea, oat+si!l1ji <strong>and</strong> oat+lucerne. It was observed that row<br />

crientation had a tremendous influence on herbage productivity. The SE-NW orientation<br />

yielded 28% more over N-S <strong>and</strong> NE-SW. Similarly, E-W orientation also gave 18% more<br />

yi~ld over NE-SW <strong>and</strong> N-S. The highest yield was noted with pure oat <strong>and</strong> inrercropping<br />

with legumes depressed the total yield by 16 to 22·X,.<br />

(c. R. Hazr.i <strong>and</strong> D. P. H<strong>and</strong>a)<br />

Rainfall pattern an j probabilities.<br />

The rainfall variability-distribution of rainy days, probability of rain faIl <strong>and</strong> recurrence<br />

interval for drought were studied for Lalitpur <strong>and</strong> B<strong>and</strong>a districts of Bundelkh<strong>and</strong> region<br />

based on 17 years data. It was found that the rainfaIl received during four months of June­<br />

September accounted for 91 per cent of the annual total at Lalitpur with 8 per cent distri-<br />

. buted in remaining months. Similarly, at B<strong>and</strong>a 75-89 per cent rain occurs between June­<br />

September. The yearly variability of rainfall is about 43-63 per cent at Lalitpur <strong>and</strong> 10-25<br />

. per cent at B<strong>and</strong>a. The average rainy days worked. out to be 49 at Lalitpur <strong>and</strong> 45 at B<strong>and</strong>a.<br />

The rainfall per rainy day is 19,1 mm at Lalitpur <strong>and</strong> 18.5 mm at B<strong>and</strong>a The expected rainfaIl<br />

during monsoon months of June-July for two years recurrence interval were 77, 383, 324 <strong>and</strong><br />

j<br />

160 mm for Lalitpur <strong>and</strong> 46, 236,324 <strong>and</strong><br />

•<br />

118 mm for B<strong>and</strong>a, respectively. The probability<br />

of occurrence of drought is once in every three years ~n the month of June <strong>and</strong> September<br />

<strong>and</strong> once in seven years in July <strong>and</strong> August. The probability of occurrence of drought is once<br />

in three years at Lalitpur in June <strong>and</strong> July, while it is thrice in twenty years at B<strong>and</strong>a for the<br />

corresponding months' In August also, the probability of drought IS once in 9 years at<br />

B<strong>and</strong>a.<br />

Distribution of dry <strong>and</strong> wet spell.<br />

The rainfall data for Jhansi (1971-82), B<strong>and</strong>a (1955-77) <strong>and</strong> LaIitpur 0955-77) were<br />

analysed to know the dis! r.bution of dry <strong>and</strong> wet spells. At Jhansi, average number of wet<br />

days were 38.2 with maximum of 57 days .in 1977 <strong>and</strong> minimum of 20 in 1979. At Lalitpur<br />

105


maximum number of wet days were found to be 52 in 1961 while minimum were 3 in 1955<br />

with an average number of 35.1 At B<strong>and</strong>a, maximum number of wet days were found to be<br />

'43 in 1971 <strong>and</strong> the minimum of 6 in 1956 with an average number of 29.4 The X 2 test<br />

indicated that weather of a particular day is Independent of the weather of the immediate<br />

preceding day.<br />

At Jhansi, the average dry run was found to be 4.8 units <strong>and</strong> wet run 2.6 units. The<br />

average dry-wet cycle was of 7 units. It was also found that expected length of dry run was<br />

always greater than expected length of wet run. At Lalitpur, the average dry <strong>and</strong> wet run was<br />

found to be 6.8 <strong>and</strong> 2.1 units respectively. The average dry-wet cycle was 9.0 units. At B<strong>and</strong>a<br />

the average dry run was 7.2 <strong>and</strong> wet 1.8 units with average dry-wet run of 9.0.<br />

SS-2: SOIL STUDIES OF RANGELANDS AND PASTURES<br />

2.1 Studies on soil fertility status of grass covers of different districts of Bundelkh<strong>and</strong>.<br />

(S. B. Tripathi, C. R. Bazra <strong>and</strong> R. K. Tyagi)<br />

Soil samples from grazing. l<strong>and</strong>s in districts Damoh, Panna, Sagar <strong>and</strong> Chhatarpur were<br />

collected to study the effect of grass species <strong>and</strong> grazing on soil fertility status. It was observed<br />

that the grass cover under Dichanthium species in Damoh district had high fertility in terms<br />

of organic carbon, available N<strong>and</strong> P followed by Heteropogon <strong>and</strong> Themeda species in Sagar<br />

district Digiteria species in Chhatarpur <strong>and</strong> Sehima spp. in Panna district. In Panna district<br />

the soil fertility status in hilly terrain was found to be higher than plain area under natural<br />

covers of Sehima during rainy Season followed by crop cultivation during winter. Dichanthium<br />

<strong>and</strong> Het eropogon grass covers in Damoh <strong>and</strong> Sagar districts helped in building up higher soil<br />

fertility status with increased organic carbon, available N<strong>and</strong> P. Moreover, the soil moisture<br />

content in black soil was greater than red soil in respective grass covers.<br />

2.2. Studies on bacterial mediated N 2-fixation for increased productivity in pasture<br />

pure cu t ire suspension of an efficient strain of Rhizobium to find' out optimum requirement<br />

of S<strong>and</strong> Zn,<br />

In g-neral, simple seed inoculation registered 19.21% higher green matter yield over<br />

uninoculated control. The combined treatment of 20 kg S/ha <strong>and</strong> inoculation showed further<br />

improvement in green yield to the extent of 27% Inoculation significantly increased nodulation<br />

<strong>and</strong> dry matter yield of C pcbescens.<br />

20 kg Sulphur/h]. interacted significantly with Rhizobium in increasing green forage<br />

y.eld of Stylosanthes hamata <strong>and</strong> the increase was of. the order of 35.4% Significant effect on<br />

nodulaton <strong>and</strong> dry matter yields was also noticed due to inoculation <strong>and</strong> sulphur fertilization.<br />

Application of 30 kg ZnS04/ha in presence of Rhizobium exhibited significant enhancem.nt<br />

in green <strong>and</strong> dry matter yields Centroccma pubescens. However, maximum nodulation<br />

was recorded at 10 kg ZnSo4/ha inoculated treatment (17 nodules/plant). It may, thus,<br />

be seen that these plant nutrients when applied in appropriate quantities..remarkably increase<br />

the efficacy of culture resulting into enhanced forage yields.<br />

Response of some grass species to Azospirillum.<br />

This was the third year of the exp~rim~nt<strong>and</strong> two more cuts were taken. Significant<br />

increase in green <strong>and</strong> dry matter production was observed in all the three grasses Cenchrus<br />

ciliaris; C. setigerus <strong>and</strong> Dichanthtum annulatumy with seedling inoculation. The magnitude<br />

of increase was however, more in case of C. set igerus.<br />

2.3 <strong>Grassl<strong>and</strong></strong> <strong>and</strong> fodder atlas of Bundelkhgnd.<br />

(R. K. Tyagi)<br />

The various aspects of irrigatio 1 for the year 1981-82 wrse studied in order to update the<br />

information generated over a period of 12 years in irrigation resources which iskey factor in<br />

l<strong>and</strong> utilization particularly in Bundelkh<strong>and</strong> ragion where scarcity of water has always posed<br />

a serious problem.<br />

The study revealed that the net irrigated area ranged between 80 thous<strong>and</strong> to 1 lakh<br />

hectares in the northern districts. The districts of Tikamgarh <strong>and</strong> Chhatarpur have also<br />

recorded more than 50 thous<strong>and</strong> hectares of irrigated area. The net irrigated area is very<br />

insignificant (less than 25 thous<strong>and</strong> hectares) in the districts of Panna, Damon <strong>and</strong> 'Sagar<br />

( 107 !


which are located in the extreme south of Bunde1kh<strong>and</strong> <strong>and</strong> form -the part of Vindhyan plateau<br />

<strong>and</strong> hills.<br />

The percentage of net irrigated area to the net sown area ranges from a minimum of<br />

4.1% in Damoh to a maximum of 40.6% in Tikamgarh district. The highest percentage<br />

(above 30%) is found only in Tikamgarh district. The next range of 20-30% is recorded in<br />

Jhansi, Lalitpur, Chhatarpur <strong>and</strong> Jalaun districts. The medium range (10-20%) is found in<br />

the districts of B<strong>and</strong>a, Hamirpur <strong>and</strong> Datia, The lowest proportion (below 10%) is observed<br />

in Panna, Damoh <strong>and</strong> Sagar districts.<br />

The area irrigated more than once is recorded very insignificant throughout the region as<br />

it is less than 2 thous<strong>and</strong> hectares in Jalaun, Hami rpur, Jhansi, Chhatarpur, Panna <strong>and</strong> Damoh<br />

Only B<strong>and</strong>a has noticeable area (26483 ha) irrigated more than once.<br />

The larger area in the region is irrigated by canals particularly in the districts of B<strong>and</strong>a,<br />

Jalaun, Hamirpar <strong>and</strong> Jhansi where the percentage of canal irrigated area varies from 62.7%<br />

in Jhansi 10 94.0% in B<strong>and</strong>a district.<br />

Well irrigation is dominating (765%) in the districts of Chhatarpur, Tikamgarh, Datia,<br />

<strong>and</strong> Lalitpur. Well irrigation covers 35.7% area in Jhansi <strong>and</strong> while it IS merely 4.2% in<br />

Sagar district. Tube-well irrigation is very insignificant in almost all the districts except<br />

Chhatarpur (3%) <strong>and</strong> Lalitpur (2%).<br />

Irrigation by tanks is also neglible except in Tikamgarh, Chhatarpur, Lalitpur <strong>and</strong><br />

Panna districts where it exceeds 1%. The irrigation by other sources is noticeable in Damoh<br />

(32.8%), Sagar (31%) Panna <strong>and</strong> Lalitpur (8.9%) districts.<br />

It has also been observed that the total irrigated area has decreased in the districts of<br />

Harnirpur, Jalaun <strong>and</strong> Damoh by 9.61, 24.20 <strong>and</strong> 19.61% respectively over the base year of.<br />

1976-77. Other distncts however, have shown an increase in irrigated area during the<br />

corresponding period..<br />

The study on irrigation by different sources reveals the fact that the area irrigation by<br />

canal has decreased in Jhansi, Lalitpur, Hamirpur, Jalaun, Damoh <strong>and</strong> Chhatarpur during the<br />

period from 1976-77 to 1981-82. This is due to Silting of the reserviors resulting in the<br />

decreae in storage capacity. The area irrigated by tank has also decreased inSagar, Lalitpur<br />

<strong>and</strong> B<strong>and</strong>a districts This is being replaced by the tube-well irrigation which is becoming<br />

popular in almost all the districts. The districts of Hamirpur, Jalaun <strong>and</strong> B<strong>and</strong>a have regis-<br />

. tered an increscd of 725.70. 606.28 <strong>and</strong> 242.40% respectively in the area irrigated by tube-<br />

( 108 )


wells. DistrictJhansi recorded 682 hectares of area irrigated by tube-well for the first time<br />

in 1981-82.<br />

SOIL STUDIE~ ON AGROFORESTRY AND SILVIPASTORAL SYSTEM OF<br />

FORAGE PR0I;>UCTION.<br />

3.1 Soil fertility <strong>and</strong> plant nutrition studies.<br />

(C. R. Hazra <strong>and</strong> S. B. Tripathi)<br />

The field- studies were carried out to know the effect of N & P fertilization on forage<br />

production <strong>and</strong> soil properties under continued tree cropping system taking open canopy<br />

(winter tree) as control. The different experiments under the project are detailed below.<br />

I. P effect <strong>and</strong> forage yield with <strong>and</strong> without tree:<br />

Field experiment was laid out in two separate sets each under Albizia lebbek <strong>and</strong> in<br />

open without any tree component. Melilotus (senji) was grown in both the cases with four<br />

levels of P (0, 30, 60 <strong>and</strong> 90 kg P20s/ha). Plant samples were collected at harvest (50%<br />

flowering) for P uptake <strong>and</strong> dry fodder yield. So.H samples were also taken for determining<br />

SOlI fertility status. Photosynthetically active radiation (PAR) was measured by quantum<br />

radiometer at 13 hour on bright sunny day, one or two days prior to harvest. The results<br />

are as follows :-<br />

Forage yield.<br />

The significant response of P wag noted upto 90 kg P:!Os!h


plantation. P eresponse was noted to be 101 <strong>and</strong> 120 kg for green <strong>and</strong> 6 <strong>and</strong> 8 kg for dry<br />

fodder under open <strong>and</strong> 37 <strong>and</strong> 52 kg for green & 6 & 6 kg for dry fodder under tree canopy<br />

at 30 & 70 kg P20s/ha respectively. The forage yield of Melilotus under tree was significantly<br />

lower than open system.<br />

Nutrient uptake.<br />

The uptake of P progressively increased wJth successive increase in the level of P <strong>and</strong><br />

the highest P uptake was recorded with 90 kg P:!O;;/ha, The P uptake varied between 1.2<br />

to 46 kg P 20s/hn under tree against 2.8 to 6.1 kg P20~/ha i~' open with differential 'p levels.<br />

At 90 kg P 205/ha. the relative uptake of P by'Melilotus under tree was 75 per cent against<br />

only 43 percent without P application under siJilar canopy situation,<br />

.<br />


surface layers.<br />

The results are as follows.<br />

Physico-chemical properties of soil.<br />

Application of P under tree <strong>and</strong> open canopy increased organic carbon, available N,<br />

available P <strong>and</strong> decreased bulk density. The agroforestry system as a whole had an edge<br />

over non-tree system by improved soil productivity through decreased bulk density, increased<br />

porosity <strong>and</strong> water retention capacity. Moreover there was a decrease in PH <strong>and</strong> Eo <strong>and</strong><br />

an increase in organic carbon, avaiiable N <strong>and</strong> under Luecaena- followed by Acacia <strong>and</strong><br />

Hardwickia.<br />

Micro-meteorologica1Y:lfameter.><br />

(i) PAR: Amongst different tree covers, Leucaena allowed the least amount of light<br />

infiltration which was around 48~-;; of full light availability under ~pen canopy. This was<br />

closely followed by Acacia (65%). Under Hardwickia, the light availability on berseem<br />

canopv was 80% of the ope.l canopy.<br />

(ii) Air canopy <strong>and</strong> soil temperature: The lowest ambient temperature for air (32.80C),<br />

canopy (27.80C) <strong>and</strong> soil (24,60C) was observed under Leucqena plots. The corresponding<br />

temperatures under Acacia were 33.40C,29.0oC<strong>and</strong> 24.6oC.Hardwickia maintained higher temperature<br />

as compared to other tree species(air 34.8, canopy 30.7 <strong>and</strong> soil 26.60C) .However, the<br />

temperature under different tree covers were always lower than open canopy. The air canopy<br />

temperature difference was least under open system t3.40C). Thus, it is seen that the temperature<br />

is closely linked with rodiation availability.<br />

.(iii) Relative humidity (RH) : The tree covers maintained higher humidity <strong>and</strong> highest RH<br />

was observed with Leucaena (80%) followed by Acacia (75%) <strong>and</strong> Hurdwickia (55%). The<br />

open plots maintained low RH (50%).<br />

(iv) Relative yield: Forage yield of berseem was found to be closely related to radiation<br />

availability. The plots under Leucaena had the lowest yield of about 36% to that of open<br />

onas. The highest relative yield was found to be 78% under Hardwickia.<br />

Forage yield <strong>and</strong> nutrient uptake<br />

Phosphate fertilization increased forage yield significantly over control treatment<br />

under all tree canopies. Application of 43 kg P jha increased forage yield significantly over<br />

21,5 kg P/ha. The highest yield was, however, obtained with 64.5 kg Plha, under all<br />

situations. The response to appliep P was maximum under Hardwickia <strong>and</strong> minimum under<br />

Leucaena, Under comparable condition of phosphate application, the forage yield of bel seem<br />

( 112 )


under the Boor sf Hardwickia was found to be the least affected to light curtailment. The<br />

uptake of P by the berseem under open a-ad tree canopy was observed to follow the trend of<br />

forage yields.<br />

The study thus indicated that Hardwickia exhibited minimum ill effects of shade on<br />

bcrseem in addi tion to known gains of top feed, fuel <strong>and</strong> timber from trees.<br />

3. Nitrogen influence on forage production of safflower <strong>and</strong> Chinese cabbage <strong>and</strong> soil<br />

fertility with <strong>and</strong> without tree association.<br />

Field experiment was conducted with four levels of N (0,40 <strong>and</strong> 60 kgjha) in two<br />

separate sets on safflower (7-13-3) <strong>and</strong> Chinese cabbage, The CrOS were planted under<br />

Albizia lebbak <strong>and</strong> also in adjacent open l<strong>and</strong>. The soil was s<strong>and</strong>y loam in texture (alfisols)<br />

having pH 7.3 Ec 0.32 mhos/em, organic carbon 0.51%, available N 190 kgjha <strong>and</strong> available<br />

P 20S 20 kgjha, The radiation was measfured by Quantum Radiometer at 13 hour. The recults<br />

are as fo llows ;<br />

Forage yield<br />

The forage yields of safflower <strong>and</strong> Chinese cabbage increased significantly with an inerease<br />

in the level of nitrogen upto 60 kg N jha both under open <strong>and</strong> tree canopy. Amongst the crops,<br />

Chinese cabbage showed higher yield potential than safflower under both canopy situations.<br />

PAR <strong>and</strong> Relative yield<br />

Application of N had least influence in altering the ill effects, if any, due to radiation<br />

curtailment. The rela~ive yield of safflower varied between 68-73 per cent for green forage<strong>and</strong><br />

be.ween 70-81 per cent for dry matter. The relative yield levels varied between 67-76 <strong>and</strong><br />

68-75 per cent for green <strong>and</strong> dry matter, respctively, in case of Chinese cabbage. The relative<br />

PAR availability to safflower <strong>and</strong> Chinese cabbage was found to be 68 <strong>and</strong> 55 per cent<br />

respectively. On an average, tile relative yields of 70-85 for safflower <strong>and</strong> 70-71 % for Chinese<br />

cabbage were found under tree canopy assuming 100 per cent yield under open environment.<br />

Nutrient uptake <strong>and</strong> soil fertility<br />

Nitrogen uptake by safflower <strong>and</strong> Chinese cabbage progressively increased with<br />

increasi 19 doses of nitrogen both under tree <strong>and</strong> open canody sestems, The highest N uptake<br />

in safflower was 40.2 kg N jha under open <strong>and</strong> 27.4 kgjha under tree canopy. The corresponding<br />

values of N uptake for Chinese cabbage were 61.9 <strong>and</strong> 40.3 kg K jha. The application of<br />

113 )


N improved the organic carbon, available N <strong>and</strong> available P status of soil at harvest. The<br />

highest soil fertility status was found under tree canopy in both the crops. Safflower with tree<br />

association improved the organic carbon by 11%; available Nitrogen by4% <strong>and</strong> available P by<br />

25% over non tree association. Such increases with Chinese cabbage were 13, 2 <strong>and</strong> 9~~,<br />

respectively.<br />

4. Response of oat <strong>and</strong> barley to N fertilization.<br />

Forage yield<br />

Nitrogen application upto 120 kg{ha to oat <strong>and</strong> barley increased both green <strong>and</strong> dry<br />

fodder yields. However, significant response was observed at SO kg{ha in oat <strong>and</strong> at 40 kg/ha<br />

in barley over contrcl treatment. Nitrogen exhibited response both under open <strong>and</strong> tree<br />

canopy with both the crops.<br />

Overall effect<br />

Open <strong>and</strong> tree canopy systems differed significantly from each other in forage yield of<br />

oat <strong>and</strong> barley at all levels of nitrogen application. The crop under tree yielded less than that<br />

under open plots. The dry forage yield of oat under tree with 80 kg N {h(was almost equal<br />

to that with 40 kg N{ha under open. Similarly, the yield of barley with 120 Kg Njha under<br />

tree equalled the yield under open canopy with 80 kg Nfha.<br />

Radiation <strong>and</strong> relative yield<br />

Under tree canopy, oat <strong>and</strong> barley received 61% <strong>and</strong> 67~~ radiation respectively of the<br />

available without tree component (100%). Oat under tree received about 0.51 x3000 micro<br />

einsteen/cms seC under open. The corresponding values for barley were 0.38 X 3000 <strong>and</strong><br />

0.54x4000 micro einstein/em- sec under tree <strong>and</strong> open canopy, respectively. The relative<br />

efficacy of barley under tree was higher than oat although the absolute yield of barley was<br />

only 50% to that of oat.<br />

Nitrogen uptake<br />

Nitrogen uptake by both the crops progressively increased with an increase in the<br />

levels of nitrogen. Under no nitrogen treatment, oat removed 131 <strong>and</strong> 79 kg N/ha under tree<br />

<strong>and</strong> epen canopy respectively, whereas the corresponding values for barley were only 58 <strong>and</strong><br />

29 kg N Iha. Oat fartilized with 120 kg N Iha removed 369 <strong>and</strong> 230 kg N Iha under open <strong>and</strong><br />

tree canopy respectively. Under similar conditions, however, barley removed only 184 <strong>and</strong> 106<br />

kg N{ha.<br />

Soil fertility<br />

A vailable nitrogen, phosphorus <strong>and</strong> organic carbon status of soil after crop harvest<br />

improved with nitrogen fertili zation. Tree association also had an edge over non-tree<br />

association in improving soil fertility.<br />

(C.<br />

R. I-I,ma)<br />

I. Forage yielJ of grasses under different tree canopies in relation to radiation <strong>and</strong><br />

me.corological parameters.<br />

The experiment was oarred out in red s<strong>and</strong>y loam soil with a view to find out suitability<br />

of some important tree species for silvipastoral production system. The tree species<br />

included Albizia lebbek, A. procera <strong>and</strong> Acacia nilotic a planted at 5 m X 5 m distance in the<br />

year 1977. Another tree species, Leucaena leucocephala planted in 1979 at 4 m x 2 m distance<br />

was suitably lopped to give desired light intensity. The grasses were harvested in the month<br />

of October from 2m 2 area from middle of two rows or trees. Similarly, the grasses were also<br />

harvested from adjecent open l<strong>and</strong> without any tree compoent. The micrometeorological<br />

parameters were recorded one day prior to harvest at 13.00 hour. The photosynthetically<br />

active radiation (PAR) was measurec by quantum radiometer, relative humidity by R. H.<br />

gauge <strong>and</strong> temperature by tele iherrnometer. The relative yield is the yield under tree expressed<br />

as per cent yield of open. The relative PAR values were also calculated in similar way.<br />

Though the highest forage yield was found' with Albizia lebbek followed by open<br />

canopy (withont tree) but the differences were statistically non-significant. The forage yield<br />

under Leucaena leucocephala was, however, significantly higher than Acacia nilotica <strong>and</strong><br />

Albizia procera The PAR varied from 67% under Ai tebbek to 53% under L' leucocephala.<br />

The PAR was 61~'-;; <strong>and</strong> 57% under A. nilotica. This indicated that the forage yields were not<br />

entirely dependent on solar radiation but more so on tree-grass intertion. The higher forage<br />

yields under tree were generally associated with higher air-canopy temperature difference.<br />

2. Forage yield of grasses in relation to radiation availability.<br />

The experiment aimed at studying the influence of light quanta available <strong>and</strong> the above<br />

ground biomass production in grasses. Cenchrus ciliaris was grown under the trees of Poincine<br />

regia <strong>and</strong> Hardwickia binata in red soil. The radiation availability to underneath gasses were<br />

controlled by appropriate lopping of trees.<br />

( 115 )


The dry matter yield of grass decreased with the decrease in incident quanta on the<br />

canopy surface. The forage yield was 93% at 83% PAR <strong>and</strong> 50% at 42% PAR. Thereafter,<br />

the decrease in yield was very sharp <strong>and</strong> forage yield remained only 6% at 8% PAR. The<br />

relative humidity increased with curtailment in radiation <strong>and</strong> reverse was the trend with respect<br />

to ambient air <strong>and</strong> leaf temperature, The air-canopy temperature differences narrowed<br />

down with the decrease in PAR.<br />

3. Herbage yield of grasses in relation to radiation under silvipastoral system.<br />

A field study was undertaken with eight tree species viz., Albizia lcbbek, Albizia procera,<br />

Acacia tortilis, Acacia nilot i ca, Leucaena Leucocephala, Dichrostachys nut ans, Hardwickia<br />

binata <strong>and</strong> Eucalyptus to fiind out the influence of tree canopy on radiation infiltration to the<br />

grasses grown in association with the trees. An adjacent open plot was taken as control free<br />

from component, The study indicated that the PAR values under all the tree species were<br />

significantly lower than the open <strong>and</strong> varied between 58-83%. The PA R values were in the<br />

order of open> H. binata > D. nutans > Eucalyptus> A. tortilis> A. lebbek ><br />

A. procera> L. l eucocephala > A. nilotica. The yields under tress were significantly different<br />

from yields under open. The order of forage yield was open > A. lebbek;» D. nut ans<br />

> H. binatari: Li leucocephala;» A. nilotica> A. procera > Eucalyptus,<br />

4. Seasonal responses of different fodder crops in relation to tree association.<br />

In order to find out the suitability of fodder crops in different growing seasons under<br />

agroforestry system, their productivity was evaluated under shade conditions. The crops<br />

included were cowpea, guar, moth, field bean, sunhemp, jowar, bajra, teosinte <strong>and</strong> maize in<br />

summer <strong>and</strong> rainy season, <strong>and</strong> Chinese cabbage, safflower barley, oat, senji , lacarne, berseern<br />

<strong>and</strong> pea during winter season.<br />

The results indicated that the yields of most of the fodder crops under tree tended to<br />

increase or remained equal to that of open canopy during summer season. The situation was<br />

entirelv different during rainy season, in the sense that all the fodder crops under tree produced<br />

significantly lower yield than open canopy situation. The yields under tree canopy<br />

during rainy Season varied between 52-76% with lowest relative yield of sunhemp <strong>and</strong> highest<br />

of bajra. The crops under tree received 68% <strong>and</strong> 52% of radiation during summer <strong>and</strong> rainy<br />

season, respectively. During winter, most of the cereal <strong>and</strong> oilseded forage under tree yielded<br />

aboue 87-98% of open system. Moreover, the leguminous fodders viz" berseern, lucerne<br />

<strong>and</strong> pea yielded only 45, 55 <strong>and</strong> 63% respectively under tree. The relative yield of sen]i was<br />

116


however 83%, On an average, all the fe dder crop's under tree yielded significantly lower<br />

than open,<br />

Amongst the different napier bajra (NB) hybrids tried under tree <strong>and</strong> open, tl.e highest<br />

forage yield was recorded with <strong>IGFRI</strong>-6 followed by NB-2l <strong>and</strong> PBN-21. The yields<br />

obtained from <strong>IGFRI</strong>-3 <strong>and</strong> Setaria (N<strong>and</strong>i) were low be th in summer <strong>and</strong> rainy seasons.<br />

The relative yields under tree during summer 'varied between [\4-120% <strong>and</strong> during rainy<br />

season it ranged between 65-74~~. Setaria gave 20% more yield under tree as compared to<br />

open canopy. The radi:.tion av.ulability on crop callopy under tree was 76% of open during<br />

summer <strong>and</strong> 57~~ during rainy months. During summer, under tree, <strong>IGFRI</strong>-6 had the<br />

highest air-canopy temperature difference (ACTD) of 440C fo llowed by IGFRl-3 (4.20C)<br />

whereas NB-2l <strong>and</strong> PNB-7l had 2ADC nnd 2.8oC, respectively. Similar was the trend under<br />

open canopy. The magnitude of difference of air-canopy temperature during rainy season<br />

was leas than summer period. The low canopy temperature of <strong>IGFRI</strong>-6 <strong>and</strong> <strong>IGFRI</strong>-3 is<br />

indicative of low photorespiratory proceS5 <strong>and</strong> possible higher net assimilation.<br />

3.3 Studies on biological N 2 fixation under agroforestry system of forage production.<br />

(M. R. Pahwa)<br />

A pot trial conducted in order to select a superior combination of Subabul host/<br />

Rhizobium strain (s) for better herbage yield. The treatments consisted of three strains each<br />

of host EL selvador, K-8 <strong>and</strong> K-28 <strong>and</strong> Rhizobium (TAL-582, TAL-1158 <strong>and</strong> LL-28-2<br />

applied individually <strong>and</strong> in combination). The experiment was terminated after 80 days.<br />

Variety K-8 produced highest green <strong>and</strong> dry matter yields when inoculated with combined<br />

strains of Rhizobium. However, there was no significant effect of these strains on nodulation<br />

Superior performance in terms of herbage yield was also recorded with combination of<br />

K-28/TAL-582.<br />

Performance of different Acacia species to inoculation with Rhizobium strains<br />

Three Acacia spp. (A. tortilis, A. arabica <strong>and</strong> A. planitormisv were tested against<br />

three Rhizobium strains (R-9, R-3 <strong>and</strong> cowpea Rhizobium) singly <strong>and</strong> in combination, Nodulation<br />

growth <strong>and</strong> herbage yield were recorded after 90 days. Surface sterilized seeds of<br />

A. planiformis when inoculated with combined Rhizobium (R-9+R-3) produced significant<br />

effect on plant height (56.9 em) <strong>and</strong> herbage yield (14.0 g/plant). Nodulation was also<br />

stimulated with combination as compared to their independent application. However, application<br />

of Rhizobium to A. torti/is seeds gave superior performance in respect of herbage<br />

accumulation (6.0 g/plant).<br />

SOILS IN RELATION TO FORAGE<br />

4.1 Soil fertility <strong>and</strong> plant nutrition studlec in acid soils.<br />

(S. B.Tripathi <strong>and</strong> N. D. Mannikar)<br />

'1. Efficiency of N sources at different levels of N in acid soils.<br />

Pot culture studies revealed that the maximum green (369.8 g/pot) <strong>and</strong> dry (89.3<br />

g/pot) matter yields were recorded at 120 kg N Iha. Amongst N sources, the effect of calcium<br />

ammonium nitrate (CAN) was found significantly superior to urea ond FYM. Palampur<br />

soil produced significantly higher green <strong>and</strong> dry fodder yields as compared to Jorhat<br />

<strong>and</strong> Mannavanore soils. The interactions, soils X sources Xlevels were not significant.<br />

Increasing doses of N increased N content in oat <strong>and</strong> maximum concentration was<br />

found at 120 kg N/ha. As regards sources, CAN was found to be superior to others. The<br />

concentration of N in plants was maximum in Palampur soil. Jorhat soil was found to be<br />

intermediate. Least N content in plant was found in Mannavaoore soil.<br />

The data on soil analysis after harvesting of oat crop indicated that the avai lability of<br />

N increased with increasing levels of N. The availablility of N was maximum in Mannavauore<br />

soil with FYM treatment.<br />

2. Response of Mo with <strong>and</strong> without P application on forage production in acid soil.<br />

The green <strong>and</strong> dry matter yields of berseem increasedsignificantly with increasing level<br />

of Mo <strong>and</strong> P. The interaction effect between P was also found significant. The highest<br />

green (340.1 g/pot) <strong>and</strong> dry fodder (37.2 g/pot) yields were recorded with 80 kg P 205 <strong>and</strong><br />

1.5 kg MoOa/ha.<br />

Mo <strong>and</strong> P content in plant increased with increasing levels of Mo <strong>and</strong> P.. However,<br />

P <strong>and</strong> Mo contents increased significantly with 1.0 kg MoOa/ba over control treatment. The<br />

increase in Mo from 1.0 to 1.5 kg Mo 0a/h1 did not alter the Mo content but caused significant<br />

variation in P concentration. The application of P significantly increased Mo <strong>and</strong> P<br />

contents over no P treatment. The interaction effect between P <strong>and</strong> Mo showed that significant<br />

response in terms of Mo content was noted at 1.0 kg Mo 0a/ha with P application over<br />

].0 kg Mo Oa/ha alone.' The change in P content was found to be significant with increasing<br />

levels of Mo combined with P as compared to application of Mo wtthout P. The highest Mo<br />

<strong>and</strong> P contents 16.2 ppm <strong>and</strong> 0.52 percent, respectively were found with combined application<br />

of 1.5 kg Mo 0a <strong>and</strong> 80.kg P 20,j/l1a.<br />

Eichanthium based pastures for their sustained productivity.<br />

(P. Rai) ,<br />

1. Effect of time of sowing <strong>and</strong> with <strong>and</strong> without pelleting on the establishment of grasses<br />

<strong>and</strong> legumes.<br />

Studies on the establishment of Cenchrus ciliaris, Dichanthium annulatum, Stylosanthes<br />

hamata <strong>and</strong> S. scabra separately were continued for the second year with three times of sowing<br />

'(mid1le of May, June <strong>and</strong> July) <strong>and</strong> with <strong>and</strong> without pelleting.<br />

The plant population differed significantly with different times of sowing in all the<br />

species except S. scabra. The maximum plant population of 21875, 36875, 66875 <strong>and</strong> 82500<br />

plantsjha was recorded in S. hamata, S. scabra, D. anulatum <strong>and</strong> C. ciliaris,,respecti,!ely<br />

when sowing wasdorie during middle of July followed by middle of June in both che species<br />

of grasses <strong>and</strong> legumes. Mid July sowrng gave significantly higher plant pepulation compared<br />

to middle of May sowing in.all the species.<br />

\<br />

Only C. ciliaris gave significant differences in plant pop~latio~.drte to pelleting­<br />

However, the maximum plant population of 15833, 35000, 58750 <strong>and</strong> 60000 plants/ha was<br />

obtained in S, hamata, S. scabra, D. annulatum <strong>and</strong> C. ciliaris, respectively when pelleting<br />

was done with clay soil. .."<br />

2. Effect of seed rates <strong>and</strong> method of sowing on the establishment of Dichanthum<br />

( 119 )


2 methods of sowing (broadcast <strong>and</strong> line sowing) on the estabishment of D. annulatum cv.<br />

S-32 <strong>and</strong> C. ciliaris cv. S-3108 separately.<br />

Significant differences in plant population due to different seed rates in both the<br />

grasses were observed. The maximum plant population of 1,06,667:.lnd 1,65,000 plants/ha<br />

was recorded C. ciliaris <strong>and</strong> D. annulatum, respectively when sowing was done at the rate of<br />

10 kg/ha. However, plant population recorded with 4 to 10 kg/ha gave statistically nonsignificaru<br />

results in both the grass species. The method of sowing did not show significant<br />

effect on plant population. However, the maximum plant populations of 82,000 <strong>and</strong> 1,31,333<br />

plams/ha were recorded with C. ciliaris <strong>and</strong> D. annulatum, respectively whensowing was<br />

done by broadcastir g compared to line sowing in both the grasses.<br />

There were no significant differences in plant height, number of tillers/plant, tussock<br />

diameter <strong>and</strong> dry matter yield due to different seed rateS <strong>and</strong> methods of sowing in both the<br />

grass species except seed rates for dry matter production. The maximum dry matter yield of<br />

22.5 <strong>and</strong> 15.8 qjha was obtained in C. ciliaris <strong>and</strong> D. annulatum respectively when sowing<br />

was done at the rate of 10 kg seed/ha. However, the dry matter yields obtained with 4-10 kg<br />

seed/ha in case of C. ciliaris <strong>and</strong> 6 to 10 kg/ha in case of D. annulatum were not found to<br />

be statistically significant. In both the grasses, the dry matter yield was higher in broadcast<br />

method of sowing as compared to line sowing though, it was statistically non-significant.<br />

3. Effect of planting material <strong>and</strong> frequency of weeding on establishment <strong>and</strong> production<br />

in Dichant hium annulatum.<br />

Studies were continued for the second year with three planting materials (seeds,<br />

seedlings <strong>and</strong> rooted slips) <strong>and</strong> three frequencies of weeding (0, I <strong>and</strong> 2 wee dings during rainy<br />

season) to know the effect of planting material On establishment <strong>and</strong> production in<br />

D. annulatum cv. S-32.<br />

Establishment studies revealed that plant population differed significantly due to<br />

different planting materials <strong>and</strong> frequencies of weeding. Planting by seedlings gave significantly<br />

'higher establishment (l00 per cent)' than rooted slips (87 per cent) <strong>and</strong> seeds (76.6 per cent).<br />

There was no beneficial effect of two weedings compared to one weeding on the establishment.<br />

'Data on plant he'gh., number of tillers/plant <strong>and</strong> dry matter yield showed significant<br />

differences due to different planting materials <strong>and</strong> frequencies weeding. The maximum plant<br />

height (114.8 em), number of tillers/plant (40.0) <strong>and</strong> dry ,matter yield (21.8 qj ha) were recorded<br />

when pl inting was done by seedling followed by rooted slips. Dry matter yield, plant<br />

height <strong>and</strong> number of tillers/plant recorded with planting by. seeds Were significantly lower<br />

than planting by s.edlings <strong>and</strong> rooted slips.<br />

120 )


As regards to frequency o-f weeding, it was observed that there was no difference in<br />

dry matter yield, plant height <strong>and</strong> tiller number due to one or two weedings. Weeding once<br />

or twice during rainy season gave significantly higher dry matter yield as well as plant height<br />

<strong>and</strong> tiller production compared to without weeding.<br />

4. Effect of different levels of phosphorus on the prod.ictivity of Stylosantltes guianensis<br />

'a 'ieues.<br />

During the second year of an experiment with tWJ varieties of S. guianensis (Endea-,<br />

vour <strong>and</strong> Schofield) <strong>and</strong> three levels of phosphorus (0,40 <strong>and</strong> '30 kg P20 5 / ha variety Schofield<br />

produced higher-green (164.6 q/ha) <strong>and</strong> dry (63.0 q/ha) forage compared to variety Endeavour<br />

(156.3 q/ha green <strong>and</strong> 58.3 q/ha) dry though, the di Tercnces were statistically nonsignificant.<br />

A pplication of different levels ofphosphorus showed significant differences in<br />

green <strong>and</strong> dry forage yield. The maximum green (171.9 q/ha) <strong>and</strong> dry (65.3 q/ha) forage<br />

yield was obtained with application of 80 kg P205/ha, followed by 40kg P 205/ha(green 165.9;<br />

q/ha) <strong>and</strong> dry 62.8 q/ha). The differences in green <strong>and</strong> dry forage yield obtained with 40<br />

<strong>and</strong> 80 P205/ha were statistically non-significant. Further, the plant vigour showed no significant<br />

differences due to different levels of phosphate application or different varieties. However,<br />

variety Schofield 1279 em) attained the maximum length.<br />

The crude protein content exhibited no variation in both the varieties (10.99 percent<br />

respec.ively in endevour <strong>and</strong> Schofield). Application of phosphorus increased the C. P.<br />

content in both the varieties, However, the was no beneficial effect of incresing the levels<br />

of phosphorus from 40 to 80 kg P 2 0 5 / ha in both the varieties, The maximum C. P. content<br />

of 11.33 percent was recorded with 40 kg P 205/ha followed by 80 kg P 20.>/ha (60.94%).<br />

The crude protein content exhibited no variation in both the varieties (10,99 percent<br />

respectively in endevour <strong>and</strong> Schofield). A pplication of phosphorus increased the C. P.<br />

content in both the varieties. However, there was no beneficial effect of increasing the level<br />

of phosphorus from 40 to 80 kg Pz0 5 /ha in both the varieties. The' maximum C. P. content<br />

of 1l.33 percent was recorded with 40 kg Pz0 5 / ha followed by 80 kg Pz0 5 /ba (10,94 percent)<br />

5. Effect of different levels of nitrogen on the productivity of pure <strong>and</strong> mixed.st<strong>and</strong> of<br />

Cenchrus hybrid.<br />

The experiment was continued for the second year of Cenchrus hybrid with three<br />

levels of nitrogen (0, 30 <strong>and</strong> 60 kg N /ha) on the productivity of pure <strong>and</strong> mixed st<strong>and</strong> with<br />

Stylosanthes hamata. Five cuttings were taken on 23.2.84, 21.7.84, 16.8.84, 17.9:84 <strong>and</strong><br />

\ ( .. 121


18.10.84 from the grass while only one cutting was taken on 23.10.84 from S. hamata since<br />

S. hamata was sown during July, <strong>1984</strong> due to high 'mortality of S. guianensis durmg<br />

1983.<br />

The application of nitrogen significantly incressed the forage yield of pure st<strong>and</strong> while<br />

mixed st<strong>and</strong>s it was not significant. The maximum dry matter yield of 153.9 q/ha was reCorded<br />

with 60 kg N/ha followed 'by 30 kg N/ha (139.3 q/ha) when . g~own in pure st<strong>and</strong>. The<br />

maximum dry matter yield of 104.1 q/ha (9583 q/ha from gr.lss+8.3 qjha from S. hamata)<br />

was observed in the mixture of Cench~us hybrid+S. hamata (control).<br />

Data on plant height, tussock di-rneter <strong>and</strong> number of tilbrsjp\anl showed no significant<br />

differences, However, the maximum plant height (156.5 cmj W.lS observed in-pure<br />

st<strong>and</strong> with application of 60 kg N /ha while the maximum tussock diarneter . (21.0 ern) <strong>and</strong><br />

number ef tille rs/phnt(4.7) were recorded in the mixed st<strong>and</strong> with 60 kg Njha,<br />

The C. P. content in grass increased with application of nitrogen in pure as well as<br />

mixed st<strong>and</strong> with S. hamata. In all She mixtures the C. P. content was higher compared to<br />

pure st<strong>and</strong> except at 60 kg Njha.<br />

The application of 60 kg N Iha in pure st<strong>and</strong> gave maximum C. P. content (11.11<br />

percent) <strong>and</strong> the minimum (10.15 percent) was recorded in control (grass alone), Further<br />

it was observed that the C. P. content in S. hamata also increased with the increasing levels<br />

of nitrogen.<br />

6: Ccrnpara ti\ e studies on the effect of fertilizers <strong>and</strong> introduction of legumes on the<br />

productivity of established pastures of Dichanthium <strong>and</strong> Cenchrus.<br />

Comparative studies were continued for the second year to know the effect of fertilizers<br />

(0, 60 kg Njha, 30 kg P205/ha <strong>and</strong> 60 kg N+30 kg P20.;/ha) <strong>and</strong> introduction of four<br />

perennial legumes (M,acroptilium at ropurpureum, Clitoria ternat ea, Stylosanthes hamata<strong>and</strong><br />

S. scabra) with <strong>and</strong> without application of 30 kg P 205/ha on the productivity of established<br />

pastures of D. annulatum cv. S-32 <strong>and</strong> C. ciliaris cv, S-3108. Three cuttings were taken on<br />

23.7.84,3.984 <strong>and</strong> 16.10.84 in case of C. ciliaris while five cuttings were taken in D. annula<br />

tum on 23.2.84,16.4.84, 13.8.84 18.9.84;<strong>and</strong>,~6.10·84. Total in all, the three cuttings in<br />

C encht us <strong>and</strong> five cuttings in Dichanthium were used for statistical analysis,<br />

The forage yield (OM) differed significantly with various treatments in both the grass<br />

species. In case of C. ciliaris the maximum dry matter yield of 80.5 qjha (52.4 q/ha from<br />

grass+28.1 q/ha legume) was obtained with introduction of S. hamata+application of 30 kg<br />

122 )


P:J0s/ha (61.1 q/ha) <strong>and</strong> introduction of S. hamata (59.2 q/ha). The minimum dry matter<br />

yield of 40.4 q/ha was recorded in control. In case of D. annulat um, the maximum dry<br />

matter yieid of 74.0 q/ ha was recorded with application of 60 kg N/ ha+30 kg P:J0s/ha followed<br />

by introduction of S. hamata-rsts kg ,P 20s/ha<br />

(67.6 q/ha from grass-l-Si I qrha from<br />

legume=72.7 q/ha) <strong>and</strong> introduction of M. atropurpurcum-l-J kg P 20s/l1:i (68.3 q/ha from<br />

grass-t2,8 q/ha from lcgume",=71.1 q/ha). The minimum dry rnatu r yield of 42.3 q/ha was<br />

recorded in ccn.rol.<br />

significant differences in plant height due to different treat nen,s was not observed in<br />

roth the grasses. However, the maximum plant height of i21.3 ern <strong>and</strong> 108.9 cm was noted<br />

i.i C. ciliaris <strong>and</strong> D. annulatt.m respectively with introduc ion of M. £IIropurpureum-s- 30 kg<br />

P 20,,/ha in case of C. ciliuris <strong>and</strong> with 60 kg N-j-40 kg PllO[,/ha in case of D. annulat um,<br />

t<br />

Studies on crude protein content revealed that due to application of fertilizers <strong>and</strong> introduction<br />

of various legumes, the CP content increased in ail the treatment combinations in both<br />

the grasses as compared to control. The maximum CP content of 9.36 percent was recorded<br />

in case of C.ciliaris with introduction of Mvatropurpurcum-r si) kg P 20s/ha followed by application<br />

of 60 kg NJha (9.27 percent) <strong>and</strong> introduction of S. hamata-s-st) kg P20S/ha (91.0<br />

percent). The maximum CP content of 7.61 percent was noted in control: In case of<br />

D. annulatum the maximum CP content of 8.14 percent was observed with introduction of<br />

M. atropurpurcum followed by introduction of S. hamata alone (8.05 percent) <strong>and</strong> S. hamata<br />

+30kg K 20n /ha (7.88 percent). The minimum CP content of 7.0% was noted in control<br />

Fur ther, it was seen that the CP content increased in all the introduced legumes due to application<br />

of 30 kg P20s/ha in both the grasses species. Among the legumes, the maximum C P<br />

content was recorded in C. t ernatca <strong>and</strong> the minimum in case of S. scabra in both the<br />

grasses.<br />

Studies were repeated during the year with three spacings (50, 75 <strong>and</strong> 100 em) <strong>and</strong><br />

three levels phosphorus (0, 30, <strong>and</strong> 60 kg P 20s/ha) in .Cehchrus ciliris <strong>and</strong> Dichanthium<br />

annulatum to know the suitable spacing for intercropping of Sesbania sesban for getting .the<br />

high.r quality forag-, Three cottings were taken on 19.7.84, 27,8.84, & 1.1084 in case of<br />

C. ciliaris <strong>and</strong> five on 23.2.84, 16.4.84, 4.5.84, 17.9.84 <strong>and</strong> 2.11.84 in case of D. annulatum,<br />

Total of all the CUiS were utilized for statistical analysis in both the grasses.<br />

Results oft dry matter yieid exhibited that there was nc significant response due to<br />

different spacings <strong>and</strong> phosphate application on grass or legume as well as total yield of<br />

grasa-j-legume in both C. ciliaris <strong>and</strong> D. annulatum, However, the maximum dry matter<br />

yield of 79.5 <strong>and</strong> 55.8 q/ha WJ,s obtained with C. ciliaris <strong>and</strong> D. annulatum, respectively wi.h<br />

50 ern spacing. In case of S. sesban, the maximum dry matter yield of 1.1 <strong>and</strong> 8'9 q/ha was<br />

recorded when interetopped in C. ciliaris <strong>and</strong> D. annulatum, respectively at 75 em spacing,<br />

However, the coral yield (grass-j- legume) of 80..4 <strong>and</strong> 61.8 q/ha was nc ied with C. cilia. is<br />

<strong>and</strong> D. annulatum respectively at 50 ern spacing.<br />

With application of phosphorus, there was no variation in dry matter yield of grass as weill<br />

as legume in caSe of C. ciliaris while in case of D. annulatum, the maximum dry matter yield<br />

of grass' <strong>and</strong> Iegurne was recorded at 60 kg P205/ha' Further, it was Seen that due to high<br />

mortality of Sesbania, the dry matter yield of legume was very low in both the grasses as<br />

compared to previous year. Data on plant height, <strong>and</strong> number of tillers/plant revealed no<br />

significant variation due to different spacings <strong>and</strong> levels of phosphate application in both the<br />

grass species.<br />

Results on crude protein conten showed that there was not much variation in C P<br />

content of both the grasses as well as Sesbania due to different spacings. However, the<br />

maximum C P Content of D. annulatum <strong>and</strong> legume was 6.21 <strong>and</strong> 21.24 per cent respectivelv.<br />

The C P content of 6.91 per cent in C. ciliaris <strong>and</strong> 21.36 per cent in legume was recorded at<br />

the spacing of 100 em. As regards the application of phosphorus also, there was not much<br />

variation in C P content of both the grasses as well as in Sesban'a. However, the maximum<br />

C P content of 6.82 per cent in grass <strong>and</strong> 21.05 per cent in legume was recorded in case of<br />

C. ciliaris <strong>and</strong> in case of D. annulatum, the highest C P content of 6.33 per cent in grass <strong>and</strong><br />

20.98 der cent in legume was noted when 30 kg P 2 0 ,j/h:t was applied.<br />

8. Effect of spacing <strong>and</strong> cutting regime of Sesb.uii a sesban on the productivity of Cenchrus<br />

ciliaris under intercropping system.<br />

The experiment was continued for the second<br />

year with 3 spacings (50, 75 <strong>and</strong> 10) em)<br />

of C. ciliaris <strong>and</strong> 3 cutting heights of intercropped Sesbania (i5, 30 <strong>and</strong> 4S em, to know the<br />

suitable spacing <strong>and</strong> cutting height for getting the maximum quality forage from C. ciliaris<br />

<strong>and</strong> S. sesban.<br />

Results on dry matter yield revealed that there was no significant effect of different<br />

spac.ngs on the dry matter yield of grass, legume <strong>and</strong> grass+legume. However, the maximum<br />

dry matter yield of 55.01 q/ha (5495 q/ha fro.n grass-t-o.tz q/ha frorn legume) was obtained<br />

witn 50 cm spacing followed by 75 em spacing (53.84 q/ha from gras


legume=54.37 qjha). The minimum yield of 47.71 qjha (47.03 q/ha from grass +0.68 qjh'l<br />

from legume) was recorded with 100 em spacing. There was no significant difference on dry<br />

matter yield of grass, legume as well as grass-l- legume due to different cutting heights of<br />

Scsbania. The dry matter yield obtained from grass-l-Iegume at 30 em cutting height (52.58<br />

q/ha) <strong>and</strong> 45 em cutting height (52.82 q/ha) was at pal. The dry matter yield obtaied from<br />

Sesbania was very low as compared to previous year due, to higher mortality of the plantsduring<br />

the summer season. Thus, it showed that Sesbania is not suitable under rainfed<br />

conditions, under frequent cutting system. Further, the mortality of plants at 15 em. cutting<br />

height was higher as compared to 30 <strong>and</strong> 45 cm cutting heights. Data recorded on plant<br />

height <strong>and</strong> number of tillersjplant also showed no significant variation due to different<br />

sf acings <strong>and</strong> cutting heights.<br />

Results on crude protein content showed the 50 cm sraCIng gave slightly higher C P<br />

content (6.75 per cent C. ciliaris while C P content in S. sesban was higher (22.10 per cent)<br />

at 100 em spacing. The cutting at 45 em height gave higher C, P. content in both Cenchrus<br />

(6.93 per cent) <strong>and</strong> Sesbania (22.67 per cent) followed by 30 cm cutting height (6.50 per cent<br />

in C. ciliaris <strong>and</strong> 21.96 per cent in S. sesban,<br />

9. Effect of management practices on the productivity of grasses<br />

(a) Cenchrus ciliaris, Studies were continued for the third year with 3 weeding treatments<br />

(0, 1 <strong>and</strong> 2 weeding during rainy season) <strong>and</strong> nitrogen versus legume treatment (0 <strong>and</strong> 60 kg<br />

N/ha <strong>and</strong> introduction of Stylosanthes hamata in the interspaces of two rows of grass) to<br />

know the productivity of C. ciliaris uuder various management practices. Three cutting were<br />

taken on 19.7.84, 25.8.84 <strong>and</strong> 17'10.84.<br />

The results indicated that there was no significant effect of weeding on dry matter production.<br />

However, weeding gave higher dry matter yield than without weeding. Further, weeding twice<br />

during rainy season did not show much benefit for dry matter yield (60,66 q/ha) as compared<br />

to weeding once (59.95 q/ha). Significant effect on dry matter yield was recorded due to<br />

introduction of S. hamata. The maximum dry matter yield of 56.66 qrha (48.40 qjha from<br />

grass+8.26 q/ha fr ..m S. hamata) was obtained with introduction of S. hamata followed by<br />

application Of 60 kg N/ha (54.05 q/ha) <strong>and</strong> control (46.04 q/ha).<br />

Data recorded on plant height, number of tillers/plant <strong>and</strong> tussock diameter showed<br />

that there were no significant differences in these characters due to different weeding treatments<br />

as well as application of nitrogen <strong>and</strong> introduction of S. hamata. However, weeding gave<br />

h gher number of tillers/plant as compared to without weeding. Application of fertilizer as<br />

well as introduction of S. hamata also showed higher number of tillers/p!ant, than ~o~tro)·..<br />

The application of nitrogen as well as intercropping of annual legumes increased the<br />

C P content in C. ciliaris. The maximum C P content of 8.05 percent was recorded with<br />

application of 60 kg Njha followed by intercropping of guar (7.61 percent) <strong>and</strong> arhar (7.43<br />

percent). The minimum C P content of 6.82 percent was recorded in control.<br />

. Thus, intercropping of annual legumes was found to be beneficial in C. eiliaris as indicated<br />

by their dry matter yield <strong>and</strong> C P content. In addition to forage, the grain yield was<br />

also obtained from these legumes as a bonus. However, out of four legumes tried, arhar<br />

was found to' be more beneficial, which also gave fuel yield of 2.1 q{ha.<br />

12. Evaluation of Dichanthium annulatum pasture with <strong>and</strong> without legume for sheep<br />

production,<br />

Studies were conducted to know the performance of M<strong>and</strong>ya sheep grazed on the pure<br />

pastnre of D. annulatum <strong>and</strong> the mixed st<strong>and</strong> of D. annulatum-t-Stylosanthes hamata. The<br />

seedlings of D. annulatum were planted in July, 1983 at 50 em between rows <strong>and</strong> 30 em between<br />

plants in case of pure st<strong>and</strong> while in caSe of mixed st<strong>and</strong>, the distance of grass was maitained<br />

1 m between rows <strong>and</strong> 30 ern between plants. S. hamata was sown in the interspaces<br />

of two rows of grass in line at the rate of 6 kg seedl ha after one week of planting of the<br />

gr .ss, In the end of November, 19n, the legume <strong>and</strong> grass were harvested <strong>and</strong> regrowth.in<br />

July, <strong>1984</strong> was utilized by grazing through M<strong>and</strong>ya sheep. The area of each pasture (pure<br />

<strong>and</strong> mixed st<strong>and</strong>) was 1000 m 2 . Four sheep of similar age <strong>and</strong> weight introduced in both<br />

the pastures for grazing on 25.7.84 <strong>and</strong> withdrown on 29.8.84 in case of pure pasture <strong>and</strong><br />

on 12.9.84 in case of mixed pasture when the body weight of sheep was started decreasing,<br />

Again regrowth of the pastures during the month of October, <strong>1984</strong> were utilized for second<br />

rotation of grazing. In both the pastures again same number of sheep were introduced for<br />

grazing on 12.10.84 <strong>and</strong> withdrawn on 2.11.84 when the body weight again started decreasing;<br />

The body weights of sheep recorded at one week interval.<br />

The forage production was also recorded at three weeks interval in both the pastures<br />

The dry matter yield at the time of introduction of animals for grazing (25.7.84) was 22.1<br />

<strong>and</strong> 22.2 q{ha (17.4 q{ha) from grass +4.8 qjha from legume) in pure <strong>and</strong> mixed pasture<br />

respectively. The dry matter yield recorded on 16.8.84 <strong>and</strong> 5.9.84 in first rotation of grazing<br />

was 24.8 <strong>and</strong> 12.8 q{ha in pure pasture <strong>and</strong> in themixture of grass-j-Iegume was 19.9+<br />

4.2=24.1 q{ha <strong>and</strong> 5.6+5.2=10.8 q{ha respectively. The forage yield recorded in second<br />

rolationofgIHingon11.l0.84,2.11.84 <strong>and</strong> 16.11.84 was 19.1,21·5<strong>and</strong>5.7q{hainpure<br />

st<strong>and</strong> & 21.1 q{ha (15.6 qjha from grass-l-e.I q{ha from legume), 22.2 q{ha (I8.1 q/ha from<br />

g~ass 1"4.1 q/ha from legume), <strong>and</strong> 6.9 q{ha in the mixed st<strong>and</strong> respectively.<br />

128 )


In first rotation of grazing the body weight gain in sheep increased upto 16.8.84 <strong>and</strong><br />

maintained their initial weight upto 22.8.84 in case of pure pasture while in case af mixed<br />

p'!.sture (grass legume), the gain the body weight was observed upto 16.8.84 <strong>and</strong> maintained<br />

their initial weight upto 12.9.84. Thus, it was Seen that the gain in .body weight of M<strong>and</strong>ya<br />

sheep was 47.6 <strong>and</strong> 50.0 g/sheep/day in pure <strong>and</strong> mixed pasture respectively. However,<br />

sheep grazed on mixed pasture maintained their initial weight for 28 days more while in case<br />

of pure st<strong>and</strong> 7 days only. The gain in body weight in second rotation of grazing was 27.4<br />

<strong>and</strong> 28.5 gjsheep/day in pure <strong>and</strong> mixed st<strong>and</strong> respectively.<br />

Thus, the results revealed that the body weight gain of sheep in both the pastures were<br />

almost same but the sheep mainta n id for longer duration in mixed pastures of Dichanthium<br />

+S. hamata as compared to pure st<strong>and</strong> of Dichanthium. This was bacause of the batter<br />

quality of herbage available in the mixed pasture as the forage production in both the pastures<br />

was similar.<br />

1.3 Primary <strong>and</strong> Secondary productivity of mixed <strong>and</strong> pure pastures of slratro, Dolichos,<br />

Chrysopogon <strong>and</strong> Setaria.<br />

(G. K. Dwivedi)<br />

1. Effect of N<strong>and</strong> P with the introduction of Dolichos on forage production of<br />

chrysopogon pasture under rainfed conditions.<br />

Ax experiment was repeated during (he second year with four levels of nitrogen (0,30,<br />

60 <strong>and</strong> 90 kg/ha) <strong>and</strong> three levels of phosphorus (0, 20 <strong>and</strong> 40 kg P 205/ha) in an established<br />

pasture at the spacing of 50 em x 30 em to know the optimum levels of nitrogen <strong>and</strong><br />

phosphorus for getting maximum quantity of quality forage under rainfed conditions. Dolichos<br />

was intercropped in between the pasture rows during July using a seed rate of ,20 kgrba.<br />

Results showed that the maximum mixed dry matter yield of 112.46 q/ha (108.80 q/ha<br />

grass+3.66 q/ha legume) was obtained with the appic ition of 90 kg N/ha-followed by 102.98<br />

q/ha (88.60 qjha grass+4.38 q/ha legume) with 60 kg N/ha. Minimum dry forage yield of<br />

77.25 qjha (75.84 q/ha grass+2.41 q/ha legume) was obtained in control treatment with<br />

no nitrogen.<br />

With regard to phosphorus, maximum dry matter yield of 106.49 q/ha (101'21 q/ba<br />

grass+5.28 qjha legume) was obtained with the application of 40 kg P 2 0 5/ha followed by<br />

96.17 q/ha (93.14 q/ha grass+3.03 q/ha legume) with ",0 kg P205/ha <strong>and</strong> minimum of 89.67<br />

q/ha (87.06 q/ha grass + 12.61 q/ha legume) in control (no phosphorus) plots.<br />

2. Response of. Stylosunthes species/varieties with the intercroppingof Chrysopo~on fulous<br />

'pastureun~er rainfed conditions. . .<br />

The experiment was repeated during the second year in an established pasture of<br />

Chrysopogon fulvus (Cv. Mhow). Introduction of six speciesjcultivars of stylosanthes<br />

,(S. gracilis, .S. humilis S. hamata, S. scabra 40205, S. oiscosa, S. scabra -40289) <strong>and</strong> three<br />

treatments of nitrogen (20,40 <strong>and</strong> 60 kg N/ha) alongwith control (grass alone) were imposed<br />

to select the suitable species of stylosanthes for maximum 'yield <strong>and</strong> quality of forage as well<br />

as to economise nitrogen use. The results showed that the maximum dry matter yield of 94.26<br />

qrha was obtained with the application of 60 kg N/ha followed by 92,74 q/ha with 40 kg<br />

N/ha. S. scabra-40289 produced 90.08 q/ha (8 f.35 q/l13 grass+3.07 q/lu legume). The<br />

minimum dry matter yield was obtained in control grass alone. There was an appreciable increase<br />

in crude protein content of herbage due to introduction of various species of Stylosan­<br />

'!hesas well as application of nitrogen as compared to control plots.<br />

3. Eflect of N levels on the mixed swards of Chrysopogon Iulous-Chrysopogon cv. Mhow<br />

-l-Siratro.<br />

This experiment was repeated during the year in an established pasture of Chrysopogon<br />

cv, Mhow+ siratro, six levels of nitrogen (0, 20, 40, 60, 80 <strong>and</strong> 100 kg N/ha) were applied<br />

in 1st week of July.<br />

The results revealed that the maximum mixed dry forage 'yield of 76 93 q/ha (7443<br />

q/ha grass+2.50 q/ha legume) was recorded with the application of 100 kg N/ha. Minimum<br />

forage yield of 35.64 q/ha (34.27 qjha grass-j-Ls q/ha legume) was obtained in the control<br />

(no nitrogen) plots.<br />

4. Effect of phosphorus levels on the mixed swards of ChIJ'SOpOgol1 pasture-CIIr)'sopogon<br />

cv, Mhow-l-Siratro.<br />

The field experiment was continued during the second year. The treatments consisted<br />

of six levels of phosphorus (0, 20, 40, 60, 80 a-id 100 kg P 20,j/ln). Applic.ition of 20 kg<br />

~/ha' was done as basal dose in Ist week of July in all the plots.<br />

Phosphorus application progressively increased the dry matter yield with the result<br />

that maximum dry forage yield of 54.24 q(ha (5049 q/ha grass+3.75 q/ha legume) was<br />

obtained at 100 kg P 2 0 5/ha followed by 80. 60 <strong>and</strong> 40 kg P 2 0 5/ha. The minimum dry matter<br />

yield of 37.29 q/ha (35044 qyha grass+ 1.85 q/ha legume) was obtained in control (no<br />

phosphorus) treat.n m t.<br />

5. Effect of spacing <strong>and</strong> seed rates on forage production in grasses-Setaria sphacelata:<br />

An experiment was repeated during the second year with three spacings (25, 50 <strong>and</strong> 75<br />

cm plant to plant <strong>and</strong> row to row) with six seed rates (2.5, 5.0, 7.5, 10.0, 12.5 <strong>and</strong> 15.0<br />

kgjha).<br />

Results showed that the maximum dry matter yield was obtained with narrow spacing<br />

of 25 ern x 25 em followed by 50 cm x 50 cm. As regards the seed 'rates, maximum dry matter<br />

yield was recorded with 10 kgjha followed by 12.5 <strong>and</strong> 7.5 kgjha, Minimum yield was<br />

obtained with 2.5 kg seedjha.<br />

1.5 Effect of fertilizers <strong>and</strong> harvesting schedule on below <strong>and</strong> above ground biomass in<br />

different grasses <strong>and</strong> legumes.<br />

(K. C. Kanodia <strong>and</strong> K. P. Niranjan)<br />

I. Studies on the ecology of grasses as influenced by cutting management cum fertilizers<br />

under rainfed conditions-Ifeteropogon co~tqrtlls.<br />

With a view to assess the maximised forage production under different cutting regimes<br />

this experiment w is initiated on a natural grass species viz., Ifet eropogon contortus (L) P.<br />

Beaut It involved three cutting intervals (20, 40 <strong>and</strong> 60 days) <strong>and</strong> 4 doses of N fertilizer<br />

(0,30,60 <strong>and</strong> 90 kg Njha) replicated thrice during 1982.<br />

The role of cutting interval in spear grass revealed that the maximum dry matter yield'<br />

obtained (40.030 qjha), during the growth period with 60 days cutting intervals was in two<br />

harvests during September <strong>and</strong> November <strong>1984</strong> <strong>and</strong> the minimum (44.61qjha) .with 40 days<br />

cutting interval resulting in 3 cuttings. The dry matter yield with 20 days interval remained'<br />

rearly in between the two observations (45.73 qjln) where five harves,s (10 th August-Stlrh­<br />

October 84) could be taken. However, the effect of harvesting intervals was not prominent<br />

in case of this grass.<br />

As regards the effect of nitrogenous fertilizers it was observed that the dry<br />

matter yield increased considerably with the increasing levels of fertilizers. The highest dry<br />

forage yield was obtained (54.61 q/ha) with 90 kg N/ha <strong>and</strong> the lowest (37.11 qjha) with<br />

control. However, differences between the dry matter yield with 60 <strong>and</strong> 90 kg Njha was quite<br />

clear. dry matter yield was 50% higher with the application of 90 kgjha as against no fertilizer<br />

treatment. The grass remained unproductive subsequently from middle of November under ,<br />

drylrnd conditions. .<br />

in Chrysopogon [ulnus under rainfed condition.<br />

.(a) Chrysopogon [ulous (Cv. Ch<strong>and</strong>igarh+Sesbania). The experiment was repeated for<br />

the second year. The treatments comprised of pure st<strong>and</strong> of Chrysopogon fulvus cv. Ch~ndigarh<br />

<strong>and</strong> fertilized with 0,45 <strong>and</strong> 90 kg Njha. Sesbania aegyptica was intercropped with<br />

the grass to test its efficacy in increasing the yield of herbage.<br />

The fertilizer treatments in the mixed st<strong>and</strong> consisted of all combinations of two levels<br />

of nitrogen (0 <strong>and</strong> 45 kgjha) <strong>and</strong> three levels of phosphate (0, 30 <strong>and</strong> 60 kg P20.5jha). The<br />

experiment was conducted iu R.B.D. with three replicates.<br />

Results showed that the maximum mixed dry forage yield (28.03 qjha) was obtained<br />

from Chrysopogon fulvus intercropped with Sesbani« <strong>and</strong> fertilized with 45 kg+30 of P20Sj<br />

ha, followed by pure st<strong>and</strong> of grass with the application of 90 kg Nj ha (26.16 qjha) while<br />

the minimum was abtained (16.49 q/ha) with the pure st<strong>and</strong> of grass without application of<br />

fertil izer,<br />

(b) Chrysopogon iulous (cv. Mhow+Sfylosanfhes scabra, 40289). The experiment was<br />

established Jast year <strong>and</strong> the fertilizer treatments were imposed during this year on the new<br />

growth. The treatments comprised of pure st<strong>and</strong> of Chrysopogon [ulous ev. Mhow obtained<br />

from the last year estabiishement <strong>and</strong> fertilized with 0, 45 <strong>and</strong> 90 kg N jha. Stylosanthes<br />

scabra (40289), a forage legume was intercropped with the grass to test its efficacy in icreasing<br />

yield of herbage.<br />

The fertilizer treatments in the mixed st<strong>and</strong> consisted of all combinations of two levels<br />

of nitrogen (0 <strong>and</strong> 45 kgrha) <strong>and</strong> three levels of phosphate (0, 30 <strong>and</strong> 60 kg PsOs/ha). The<br />

1. Studies on the suitability of legumes in diffr-rent grassl<strong>and</strong>s for their maximised productivity<br />

(b) Eremopogon dominated grassl<strong>and</strong> community.<br />

With the aim of finding out a suitable legume Vjs the recommended dose of fertilizer<br />

this experiment was continued during its third year on the same natural Eremopogon dominated<br />

community on the same Spot in Divisional <strong>Research</strong> Farm area. The experiments. comprised<br />

on introduction of four legumes viz. Atylosia scarabaeoides. stylosanthes hamat a.S, quianensis<br />

<strong>and</strong> siratro at the recommended seed rate along with one dose of N-fertilizer @ 40 kg<br />

N jha in the form of urea <strong>and</strong> the 6~h as the control treatment was repeated during the year<br />

in Ercmopogon dominated grassl<strong>and</strong> at~C. R. farm, Jhansi. The treatments were imposed in<br />

the end of June 84 alongwith an uniform basal application of 20 kg P 2 0 5jha!n the form of<br />

SSP in the plots (4 X 3 m size) replicated four times in R. B. Design.<br />

The data revealed more or less similar dry forage yield in each treatment ranging between<br />

15.23 qjha <strong>and</strong> 15.71 qjha in S. quainensis <strong>and</strong> with fertilizer treatment to 17.94<br />

qjha in the sirato introduced plots the con trot treatment recordedtlf·08 qjha.<br />

2. Studies on the effect of time <strong>and</strong> method of sowing of legumes (Dolichos lablab) introduced<br />

in natural grassl<strong>and</strong>s.<br />

This experiment was laid out in 1982 with the pri mary aim to know the proper time<br />

<strong>and</strong> method of sowing of Dolichos lablab in a p'lrtially protected natural grassl<strong>and</strong> under<br />

rainfed conditions, Stu-lies were repeated with three methods of introduction viz, broadcasting,<br />

dibbling <strong>and</strong> line sowing of the legume <strong>and</strong> four dates (May end, mid June, June end <strong>and</strong><br />

mid July) in split plot design replicated thrice in a Heteropogon dominated grassl<strong>and</strong>.<br />

(a) Effect of time of sowing' Data on plant population of legume Dolichos established in<br />

the grassl<strong>and</strong> revealed higher plant population (1999 q/ha) where the legume was introduced<br />

in the end of June, followed by the middle of July. The minimum establishment was recorded<br />

4.5 Ecological studies .of semi-arid grassl<strong>and</strong>s<br />

(8, K. Trivedi, K. C. Kanodia <strong>and</strong> N. C. Verma)<br />

After recording pre-treatment data in the year 1983, the observations were recorded<br />

On the following.<br />

Botanical composition: Botanical composition was studied through quadrat method<br />

<strong>and</strong> about 46 herbaceous plant species were recorded. Grasses exhibited 3/4 Important<br />

Value Index (I. V.!.) while legume <strong>and</strong> forb components of thecommunity attained 1/4 LV.L<br />

of total vegetation' Amongp:::rennial grasses Sehim neroosum an Heteropogon contortus<br />

were in present in all the treatments. On the basis of LV.I. they occupied dominant <strong>and</strong> codominant<br />

position respectively. 1. V. I. of S, neroosum ranged from 30.2 to 79.7 in T 9 <strong>and</strong><br />

T lO treatments while that of H. cont ortus was from 17.9 to 85.8 in T 7 <strong>and</strong> T 12 respectively.<br />

Among legumes <strong>and</strong> Forbs Lndigot'era astragalina <strong>and</strong> Fimbnistyllus diphylla were the prominent<br />

species respectvely, .<br />

Plant biomass: 'The' total plantfbiomass ranged from 197.8 to 368.7 g/m2 in Ts <strong>and</strong><br />

T 2 treatments respectively. The biomass was less in comparison to previous year. The data<br />

revealed more than 90 percent biomass contributed by grasses whereas 10 percent or below<br />

by I-gumes <strong>and</strong> forb components. Major biomass contributors are S. neroosum <strong>and</strong> H. cont<br />

ortus. These two species added approximately more than. 70% of t01a1 plant biomass;<br />

Although, the plant biomass of legume component was low, it was interesting to note that<br />

they showed a positive response to phosphorus fertilizer <strong>and</strong> produced maximum biomass in<br />

!7 treatment (21.2 g/m 2 ) .<br />

Secondary productivity' Eight heifers were introduced for grazing on 10.9.84 <strong>and</strong><br />

withdrawn on 15 12.84. The average body weight was 131.5 kg. The weight of these heifers<br />

were taken fortnightly, The average bc dy weight gain was 27.1 kg for grazing period<br />

which comes about J280 gm/head/day. This gave slightly higher values in comparison to the<br />

previous one.<br />

Soil moisture In all the Seasons the soil moisture was taken by gravimetric method,<br />

It varied from 7..6 to 26.5 percent in rainy season, 2.1 to 6.7 percent in summer season while<br />

O. S to 5.9 percent in winter season. The moisture was .higher at lower depths.<br />

4.6 Autecology <strong>and</strong> growth behaviour studies in different range grasses.<br />

(S. S, Parihar)<br />

.<br />

1. The effect of nitrogen <strong>and</strong> length of primary growth period on y'ield of leaf an,d stem<br />

components of Chrysopogon (ulcus.<br />

135 )


The experiment was repeated during the monsoon of <strong>1984</strong>. The influence of length<br />

of growth period of the monsoon <strong>and</strong> levels of nitrogen application on yield of leaf <strong>and</strong> stem<br />

components of Chrysopogon fulvus was studied so as to evaluate the effect of rates of nitrogen<br />

fertilizer on (1) leaf yiel.1 (2) stem yield (3) percentage leaf crude protein (4) percentage<br />

stern crude protein. F01lf primary growth periods of 15, 30,45 <strong>and</strong> 60 days were used in<br />

combination with the nitrogen treatments of 0, 45 <strong>and</strong> 90 kg N/ha per Sea~on of growth<br />

applied as single dressing at the beginning of the growth period.<br />

The data on the effect of nitrogen defoliation tratments revelled that application of<br />

nitrogen significantly increased leaf <strong>and</strong> stem yield per tiller. However, nitrogen fertilization<br />

had more p.onounced effect on stem yield der tiller as compared to leaf yield per tiller. This<br />

increase in the stem yield was 23.56 <strong>and</strong> 52.56 per cent with the application of 45 <strong>and</strong> 90 kg<br />

Njha respectively over the control, while this increase in case of leaf was 5.77 <strong>and</strong> 14.94 per<br />

cent with same ni trogen levels, Thus, the effect of nitrogen application was more pronounced<br />

in stem as compared to leaf. Therefore, weight of teaf per unit weight of stem significantly<br />

decreased with increasing the nitrogen levels. However, nitrogen application had no effect on<br />

total number of live leaves per tiller,<br />

Application of nitrogen also significantly increased the total dry matter yield. The<br />

highest yield of total dry forage of 46.02 qjha <strong>and</strong> 53.55 ~jha was recorded at 90 kg Njha<br />

<strong>and</strong> 60 days of growth respectively.<br />

Increasing the growth period from 15 to 30, 30 to 45, <strong>and</strong> 45 to 60 days also significantly<br />

increased the yield of both the components, but particularly of.stem, The increase in<br />

stem yield was 78.35, 57.77 <strong>and</strong> 65.04 per cent with increasing the growth period from 15 to<br />

30. 30 to 45 <strong>and</strong> 45 to 60 days respectively. While in case of leaf yield per tiller this increase<br />

VIas 65.96,31.78 <strong>and</strong> 28.16 per cent with the corresponding growth period. The maximum per<br />

cent increase in both the components was recorded between 15 to 30 days of growth.<br />

2. Studies on seed viability <strong>and</strong> germination in different cul rivars of Cencltrus ciliaris <strong>and</strong><br />

C. set igerus.<br />

Earlier studies on seed viability <strong>and</strong> germination with different strains of C. clliaris<br />

revealed that seeds (spikelets) maintained some viability upto 48 months from the date of<br />

initial seed collection (when stored under norrml environmental condition), An acylated<br />

glycoside of cyanidin. cynnidin-S-arabinosid-, acylated with caffeic acid was isolated <strong>and</strong><br />

characterised from the spikslets. Therefore. it was desired to conduct the bi e-assay tests with<br />

the extr.rcied phytotoxin (glycoside of cyanidin) so as to observe th e biological activity of<br />

the quantified phytotoxin.<br />

136 )


The effect of different concentrations of the glycoside (concentration expressed as<br />

optical densities) on seed (caryopsis) germination. radicle <strong>and</strong> plumule growth revealed that<br />

(table 18) percentage germination was significantly reduced in higher concentration of the<br />

pigment, while lower concentration did not influence the germination significantly. Germination<br />

media with 0.1 <strong>and</strong> 1.0 O,Ds. had stimulatory effect on radicle growth, while higher conceatration<br />

had a negative effect on root growth. Shoot growth was comparatively less affected,<br />

at higher conentration negative effect was distinct.<br />

3. Quantitative estimation of Cyanidin glycoside from viable <strong>and</strong> non-viable seeds<br />

(spikelets).<br />

In view of the vital role of phenolic inhibitors for preserving seed viability for a<br />

longer period of time it was visualised that quantitative estimation of cyanidin glycoside<br />

from viable <strong>and</strong> non-viable seeds will be useful. Studies revealed that the concentration of<br />

cyanidin glycoside was higher in viable seed as compared to non-viable seeds (table 19).<br />

Seed germination studies with Cenchrus setigerus :<br />

"Bioassay tesl~: 'Like C. ~i1iaris, bioassay tests with the extracted inhibitor of<br />

'C. jet~geruswasconducted to confirm the inhibitory effect on seed germination, radi~le <strong>and</strong><br />

plumule growth so as ~b observe the biological activity of the quantified phytotoxin. In case<br />

·ofcC.I~et'igerus also th~ pigment (acylated glycoside of cyanidin in case of C. set igerus also)<br />

had aii' inhibitory \~ffect on seed germination <strong>and</strong> shoot growth. Lower concentration had an<br />

-stimulatory effect on root growth.<br />

Owing to inhibitory effect of cyanidin glycoside on seed germination of C. Ciliaris<br />

<strong>and</strong> 9. setigerus, a bioassay test was conducted with the same concentra ion of phytotoxin 10<br />

determine if the Same concentration applied were inhibitory to germination in other kind of<br />

. seeds. Therefore, Siratro (Macroptelium- atroparpurcums seeds were used for allelopathic<br />

. - ..bioassayexperiments, since siratro (a pasture legume) represents a good germination rate.<br />

In case.of Siratro .seeds.alsq, inhibitory. effect on seed germination" plumule growth <strong>and</strong><br />

radical growth was quite distinct. However, lower concentration had a stimulatory effect on<br />

radicle growth.<br />

Quantitative estimation: Quantitative estimation of Cyanidin glycoside from viable<br />

<strong>and</strong> non-viable seed revealed the higher concentration in viable seeds as comparedto non­<br />

. viable. seeds, which confirmed the labile nature or the inhibitor,<br />

4. Studies on isolation <strong>and</strong> identification of germination inhibitors jn other range<br />

grasses.<br />

. .Inhibition o'f seed 1;ermination, a cornmonlv known allelopathic phenomenon, is of<br />

commonEccurrence I in various range grasses. Therefore, studies were initiated to isolate <strong>and</strong><br />

identify t~es~ germination inhibitors present in the diaspores by paper chromatography,<br />

absorption spectra <strong>and</strong> colour reactions. Chromatographic studies revealed the presence of<br />

flavonoid glycosides in many range grasses viz. Dlchanthium annulatum, Chrysopogon (ulous<br />

<strong>and</strong> Het eropogon contortus. Alcoholic extract of Dichant.hium annulatum seeds indicated the<br />

.presence of cyanidin <strong>and</strong> guercet in glycosides. Similar extract of Chrysopogon Iuluus seeds<br />

indicated the presence of guer.:etin glycoside. Alcoholic extract of Het eropogon con ortus<br />

,< seeds gave positive tests for phenolic by ferric chloride <strong>and</strong> aluminium chloride tests.<br />

In another experiment, relative palatability ofCenc:;rus ciliaris collections was studied<br />

using sheep as the test animal during July! August when the grass attained full bloom <strong>and</strong><br />

during September when the grass was ready for harvest. Based on the intake of grass collections<br />

during July!August, the order of preterance of collections to animals was 262, 358,<br />

Agra local, 3108, 3132, Pusa giant, Jodhpur local, 3133, 357, 59d, 303 <strong>and</strong> 214. During<br />

September, the test was repeated <strong>and</strong> it was found that the acceptability of grass collections<br />

differed from that observed during July!August The order of preference was 358, 3133,<br />

303,262, 3108, 3132, Agra local, 357, Pusa giant, 214, Jodhpur local <strong>and</strong> 59-1. Further,<br />

it was observed that the intake of forage by animal for all grass collections declined during<br />

1. Growth performance of 12 populations in agroforestry,<br />

At the completion of 3 years, K 102 recorded, the maximum collar diameter followed<br />

by silvi-4 which recorded the maximum dbh. Plant height was also maximum in silvi-4.<br />

Due to very high summer temperature <strong>and</strong> low soil moisture, Lidioersifolia showed apical bud<br />

mortality <strong>and</strong> few trees dried. K-341 continued to give the poorest growth of all.<br />

The number of flowers produced per head in each of these varieties during March­<br />

.April indicated statistically significant variation between the varieties with maximum flowers<br />

in K-341 (l63.3/heatl) followed by K-6 (l51.4/head) <strong>and</strong> the minimum in L. dioersiioiia<br />

(65.5/head). Variety K-6 showed very high Cv. (20.9~;';) while K--28 gave the minimum<br />

(5.4%).<br />

The mean pod length was the maximum in K-132 (30.69±2.4 cm) followed by El<br />

Salvador (24.79± 1.6 cm) <strong>and</strong> the minimum in L. dicersitolia (10.33 ± 1.3 ern). Pod breadth<br />

was the maximum in K-8 (2.61 ±0.1 cmj followed by K-28 (2.52±0.14 em) <strong>and</strong> the minimum<br />

in E1 Salvador (I.26±O.2 em). Number of seeds per pod were the maximum in K-132<br />

(24.2±2.27) followed by K-341 (23.4± 1.2) <strong>and</strong> the minimum in L. diuersiiolia (13.5±3.1).<br />

The empty pod weight was the maximum in K-132 (1.29±0.16 g/pod) followed by 1(-8<br />

(l 26±0.13 g/pod) <strong>and</strong> the minimum in L. dioersifolia (0.18±0.03 g). The test weight of<br />

The number of flowers per head during March the maximum in No. 12 (164.6 ± 13.9)<br />

followed by No.7 (160.4± 18.4) <strong>and</strong> the manirnum in L. pul oerulenta (42.8::!:8.1). The<br />

differences between the varieties were statistically significant. The L. collinsii flowered gregariously<br />

but did not produce any pod or seed. L. puloerulenta though flowered well but<br />

could only produce 5 very small <strong>and</strong> poor pods with a few healthy seeds. K-8 was observed<br />

late flowering t;:pc with more vegetative growth.<br />

3. Growth comparison 01 15 populations: The three plant types of Lcucaena viz., Hawiian,<br />

Peruvian <strong>and</strong> Salvador with 5 varieties in each were planted in three replications. The<br />

growth studies revealed that Silvi-4 <strong>and</strong> K-8 were the populations with maximum diameter<br />

<strong>and</strong> height. The slowest <strong>and</strong> more vigorous flowering <strong>and</strong> fruiting ones were the Hawaiian<br />

types.<br />

4. Forage production comparison of 10 varieties: This experiment was in its 6th year.<br />

The population showed 100% survival <strong>and</strong> good forage production. The peruvian types<br />

continued to give higher forage yield compared to salvador types. The total dry matter<br />

production was the maximum in silvi-4.<br />


at6 years of age (10,000 plantsjha density) while in the 2nd year it was only 0.97 t/h~. In<br />

case of L. dioersitolia, the maximum litter was observed in older plantation 1.25 t/ha (3 years<br />

root hairs was better in pH range of 7-6. Seed germination in A. lebbek was more or I-ss<br />

same throughout the pH range. However, the pH range of 8-10 was found to be better for<br />

r idicle growth.<br />

(iv) Effects of KN0 3 <strong>and</strong> Thiourea (0.1 %, 0.2°{, 0.3%, 0.4%, 0.5%, 1.0%, 2.0% <strong>and</strong> 3.0%)<br />

on seed germination of lebbek were studied. O.3%KN0 3 <strong>and</strong> 0.2% Thiourea were found to<br />

give increased germination. Thiourea was found more effective than KN0 3 .<br />

1.3 Auteeological studies on exotic multi-purpose shrubs [txee«,<br />

(P. S. Pathak)<br />

The project started during July <strong>1984</strong> <strong>and</strong> Sesbania sesban germplasm (12) obtained<br />

from Australia was studied along with one local check in detail<br />

Seed <strong>and</strong> its germination' The seeds varied in their colour from yellowish to dark<br />

green <strong>and</strong> brown with many intermediary shades. The variability was also associated with the<br />

seed germination whereby the yellowish, brown <strong>and</strong> dark green colour seeds of No.3. 5, 11<br />

<strong>and</strong> 13 gave 100% germination (table 21).<br />

No.8 <strong>and</strong> 10 gave more than 9% germination but No. L 2 <strong>and</strong> 12 gave very poor<br />

germination,<br />

Seedling growth characteristics e The seedling growth data recorded at 6 months of<br />

age (mble21) revealed that variety No.l1 <strong>and</strong> 6 recorded the maximum height growth but very<br />

poor basal diameter while No.8 <strong>and</strong> 12 gave higher diameter but medium height growth.<br />

No.1, 4 <strong>and</strong> 10 gave very poor growth. Varieties II <strong>and</strong> 9 produced maximum branching,<br />

while variety nos. I, 5,7,8, 10 <strong>and</strong> 12 did not produce any branch No. 9 appeared to give a<br />

bushy growth because branches intiatcd at a veay low level.<br />

2.1 Silvipastoral s tudies 011 fodder cum fuel trees.<br />

(R. Dtb Roy <strong>and</strong> S. K. Gupta)<br />

In a long term experiment on the growth <strong>and</strong> production of Acacia tort ilis under different<br />

spacings <strong>and</strong> the association of two Cenchrus pastures, growth parame ters like height,<br />

coller diameter (0. D.) <strong>and</strong> diameter at breast height (dbh) were recorded <strong>and</strong> all the trees<br />

of oue replication were harvested for biomass production attributes. Forage production of<br />

the pasture under trees was also recorded,<br />

Height growth; The variation height growth amongst the treatments was not found<br />

to be significant (table 22). However, the maximum height growth (9.47 ern) at 4x6 m<br />

spacing in association withSCenchrus ciliaris followed by the same tree spacing without grass<br />

reseed.ng. The height has more or less even out in the course of long period of growth. The<br />

average tree growth of the felled trees was slightly higher than the average tree growth of the<br />

whole plo t, -<br />

Growth in collar diameter : The maximum C. D. growth of 25.4 em was recorded at 4 x 6m<br />

spacing' when grown in association e. eil iaris pasture followed by 24.00 em in the same<br />

spacing but without grass reseeding <strong>and</strong> least (16.1 ern) under 4x4 m spacing without<br />

reseeding, The differences amongst different treatments were found to be significant. The C.D,<br />

growth was higher with grass reseeding compared to control (no reseeding) <strong>and</strong> was higher<br />

with e. eiliaris pasture (23.0 cm) compared to' C. set igerus (20.9 em).<br />

Growth in diameter at breast height :-Similar to the C. D. growth, the dbh was maximum<br />

(27.9 ern) at 4x6 m spacing <strong>and</strong> in association withe. eiliaris pasture followed by the no<br />

grass control at same spacing (25.5 ern) <strong>and</strong> the least (15.6 cm) under narrower spacing<br />

without reseeding. Dbh growth in general was higher with wide spacing <strong>and</strong> also in association<br />

with e. eiliaris pasture. Growth difference in dbh were highly significant.<br />

Biomass production :<br />

(a) Main bole: The maximum air dry (aerial) production (245.9 kg) of the main bole was<br />

recorded at 4x6m spacing in association with e. ciliaris pasture followed by the same spacing,<br />

but in association with e. set igerus pasture (82.1 kg) <strong>and</strong> the least (36.4 kg) at 4x4m spacing<br />

in reseeding (control). Biomass production in general was higher under wider tree spacing<br />

compared to narrower one <strong>and</strong> in association with pasture compared to control. Within the<br />

two pastures biomass production of the main bole was higher in association with e. ciliaris<br />

pasture.<br />

(b) Biomass production [rom branches: It was quite interesting to note that the biomass<br />

production from the branches in general was higher compared to main bole biomass <strong>and</strong> in<br />

some treatments it was more than double. The maximum branch biomass of 245.9 kg was<br />

recorded at 4 X 6m spacing <strong>and</strong> in association with e. ci/iaris pasture followed by 144.7 kg<br />

at same spacing but in association with e. set igerus pasture <strong>and</strong> the least (59.13 kg) under<br />

4 X 4m spacing without reseeding.<br />

Biomass production of branches showed the same trend as those of the main bole<br />

except when planted at wider spacing without grasses which recorded lower branch biomass<br />

than the bole.<br />

Total aerial biomass production: The maximum total aerial biomass of 363.6 kg was recorded<br />

under the treatment of 4x6m in association with e. eiliaris pasture followed by the same<br />

spacing treatment but in association with e. set igerus pasture (226.8 kg) <strong>and</strong> least 98.8 kg<br />

under narrower spacing with no reseeding. Total biomass production was higher under wider<br />

spacing with pasture compared to the control. The pasture biomass was higher with e. ciliaris<br />

compared to C. set igerus. Total biomass production (dry matter jha) varied from 49.4 t/ha<br />

under narrower tree spacing without reseeding to as high as 121.1 t/ha under the wider tree<br />

spacing in association with C. ciliaris pasture. The mean annual increment (MAl) worked<br />

out to be 3.8 t/ha/year under control with narrower spacing to 9.3 t/ha/year under wider<br />

spacing <strong>and</strong> in association with C. ciliaris, Thus the biomass production of A. tort ilis<br />

improved with C. ciliaris than the no pasture control.<br />

The maximum dry forage production of 3.84 t/ha was recorded from C. ciliaris-:<br />

Stylosant hes pasture at 4 X 6m spacing <strong>and</strong> minimum 3.22 t/ha from C. setigerus-Stylosanthes<br />

pasture at narrower tree spacing (table 23).<br />

like H et eropogon contortus <strong>and</strong> annual Arlstida sp. invaded the pasture.<br />

2.2 Studies on the establishment <strong>and</strong> growth of plantation specks under various<br />

sj lvlpastoral combinations.<br />

(R. Deb Roy <strong>and</strong> S. K. Gupta)<br />

The studies were continued on various growth parameters viz, height, collar diameter<br />

(C D.) <strong>and</strong> d ameter at breast height (dbh) of H ardwickia binata <strong>and</strong> Albizia amara in<br />

asseciation with grass-legume mixtures to find out suitable tree-grass-Iegume for optimum<br />

production <strong>and</strong> stock carrying capacity. Pasture. production studies under the canopy of both<br />

the tree species were also carried out.<br />

Height growth :--Growth in height of A. amara <strong>and</strong> H. binat a under different pastures <strong>and</strong><br />

spacing did not show much variation (table 24). Height growth was maximum 6.53 min<br />

treatment without pasture followed by 6.32 m in Chrysopogon-Sehima pasture <strong>and</strong> 6.09 m in<br />

C. ciliaris pasture.<br />

Collar diameter growth :-Collar diameter growth in general was higher in A, amara compared<br />

to H. binata. In A. amara maximum collar diameter (19.9 cm) was observed at 4x6m<br />

spacing when grown in association with C. ciliaris followed by 18.9 ern at narrower spacing<br />

without pasture <strong>and</strong> least in wider spacing without pasture. In case of H. bineta maximum<br />

C. D. growth of 17. '3 cm was recorded ot wider spacing in association with Chrysopogon­<br />

Schima pasture. This was followed by 16.5 em at wider spacing but in association with<br />

C. ciliaris pasture. C. D. growth in general was higher with wider spacing in case of H. binata<br />

except for the control.<br />

Cr iwth in Dbh :--Dbh growth in general was higher in A. amara compared to H. binata<br />

This wuld be due to branching habit of the former which is a typical characteristic of the<br />

species, Dbh growth was.also higher with wider spacing compared to the narrower ones,<br />

In H. binata maximum dbh grow.h of 17.3 ern was recorded in 4 x 6m spacing in association<br />

with Chrysopogon-Sehima pasture followed by 16.5 cm in the same spacing treatment but in<br />

association with C. ciliaris pasture <strong>and</strong> least 15.1 em at narrower spacing with control (no<br />

pasture). In case of A. amara the maximum dbh growth of 20 ern was observed in case of<br />

wider spacing <strong>and</strong> in association with C. ciliaris pasture followed by 18.9 em in narrower<br />

spacing but with control <strong>and</strong> least (17.0 em) in association with Chrysopcgon-Sehima<br />

pasture'<br />

( 1:0 )


Pasture production :--The dry forage production varied from 1.65 to 4.05 t/ha of which the<br />

pasture legume tStyiosanthes hamata) contributed 25-35 per cent. Forage production was<br />

higher under wider tree spacing <strong>and</strong> in association with Chrysopogon-Sehima pasture,<br />

2.3 Increasing production potential of wastel<strong>and</strong>s through sllvlpastoral system.<br />

(R. Deb Roy, B. D. Patil, P. S. Pathak <strong>and</strong> S. K. Gupta)<br />

The studies revealed that some of the perennial grasses established as early as 1977<br />

were still reasonably productive. Chrysopogon [uluus showed more persistant growth <strong>and</strong><br />

production compared to either Cenchrus ciliaris or Sehima neroosum. Cenchrus ciliaris<br />

pasture could easily be established even under a 7-8 year old Albizia procera plantation.<br />

Silvipastoral system I : Dichrostachys cinerea was established during 1981 in an earlier established<br />

Chrysopogon-Cenchrus pasture <strong>and</strong> continued to exhibit 80 per cent survival.<br />

Chrysopogon [ulous <strong>and</strong> C. ciliaris pastures recorded dry forage production of 5.2 <strong>and</strong> 4.3<br />

t/ha respectively in association with Dichrostachys cinerea. The growth of Chrysopogon was<br />

more vigorous ClS compared to that of C. ciliaris, Dichrostachys cinerea recorded an average<br />

height <strong>and</strong> collar diame .er (CD) growth of 2.90 m <strong>and</strong> 4.87 ern respectively. The maximum<br />

height <strong>and</strong> C.D. were 3.50 m <strong>and</strong> 3.8 em respectively in association with Chrysopogon-Cenchrus<br />

pasture.<br />

Silvipastoral system II :--Leucaena leucocephala (K8) introduce during 1980-81 in an<br />

established pasture showed good establishment, exhibiting mean height, C. D. <strong>and</strong> dbh of<br />

151


6.50 m, 9.59 em <strong>and</strong> 6.78 em respectively. The maximum height, C. D. <strong>and</strong> dbh recorded<br />

were 9.50 m, 14.7 em <strong>and</strong> 15.1 em respectively in association with Cbrysopogon-Cenchrus<br />

pasture. Similar to system I, the C. tulous pasture exhibited higher dry forage production<br />

(6.53 t/ha) compared to C. ciliaris (4.78 t/ha) pasture under the canopy of L. leucocephala.<br />

Silvipastoral system III :-Albizia lebbek n:cored an average height, CD <strong>and</strong> dbh growth<br />

of 7.53 m, 17.4 cm <strong>and</strong> 15.5 em respectively in association with Chrysopogon Ful ous, C.<br />

setigerus pasture which recorded dry forage production of 4.17 t <strong>and</strong> 3.25 t/ha respec.ively.<br />

Silvipastoral system IV :--In this system A. lebbek was grown in association \I ith Scl.ima<br />

nertosum <strong>and</strong> C. ciliarls pastures. They recorded forage production of 3.76 <strong>and</strong> 4.21 t/ha<br />

respectively. The pasture had a mixture of Stylosanthes scabra <strong>and</strong> S. humara respectively.<br />

A. lebbek recorded an avenge height, CD <strong>and</strong> dbh growth of 8.35 ill, 20.37 em <strong>and</strong> 17.23 em<br />

respectively.<br />

Silvipastoral system V :-In this system, pasture production of C. ciliaris was affected by<br />

the intrusion of local perennial grasses like Heteropogon contortus, Eremopogon Fooeolatus<br />

<strong>and</strong> annuals like Aristida probably because of the gaps provided by initial annual legumes<br />

introduced along with the Cenchrus grass. The pasture production thus, was much lower<br />

(~.36 t/ha) under the canopy of Albizia procera. The tree exhibited an average height, CD <strong>and</strong><br />

dbh growth of 9.80 m, 26.2 em <strong>and</strong> 27.3 em respectively. The maximum height, CD <strong>and</strong><br />

dbh were 14.6 m, 38.2 em <strong>and</strong> 29.4 em respectively.<br />

Silvipastoral VI :--In this system, Prosopis julitlor« erect type (Israeli var.), grown in association<br />

with C. ciliaris recorded an average height, CD <strong>and</strong> dbh growth of 4.95 m, 8.99 ern<br />

<strong>and</strong> 9.42 em respectively Pithecellobium dulce however, recorded height, CD <strong>and</strong> dbh growth<br />

of 4.95 m, 9.85 em <strong>and</strong> 10.37 em respectively. The forage production of 3.41 <strong>and</strong> 3.98 t/ha<br />

were recorded in Cenchrus <strong>and</strong> Chrysopogon pastures respectively.<br />

Acacia nilotica (sub sp. indica) exhibited poor performance in the skeletal soil<br />

compared to A. tortilis whereas in filled soil <strong>and</strong> under crop with partial irrigation exhibited<br />

much faster growth. In later situation, A. nilotica recorded an aVe rage height, CD <strong>and</strong> dbh<br />

growth of 9.2 m, 19'54 em <strong>and</strong> 22.23 em respectively,<br />

Silvipastoral system VIr:-It was qui te interesting to note that under the full grown tree of<br />

A. lebbek it was possible to grow L. lcucocephal« as under crop of fodder without lopping<br />

whereas the grass growth of Cenchrus was poor. A. Iebbek exhibited an average height, CD<br />

<strong>and</strong> dbh growth much better than that of system IH <strong>and</strong> IV described earlier. The maximum<br />

height, CD <strong>and</strong> dbh were 13.0 m, 31.5 em <strong>and</strong> 24.8 em respectively.<br />

152 )


Natural system : The original undisturbed natural system comprised of perennial<br />

grasses mostly Heteropogon & annuals mostly Aristida with occasional Sehima nertosum with<br />

low productivity. The average production was 1.87 tjha. There was hardly any canopy,<br />

with one or two trees of Azadircaht indica.<br />

2.4 Silvipastoral studies on D. cinerea <strong>and</strong> Albizia species.<br />

(M. M. Roy)<br />

1. D. cinerea<br />

(a) Mortality of plants over a period of 3.5 years was around 12.5~1g. Various treatments<br />

did not affect the mortality parcentage,<br />

(b) Average growth of plants in 3.5 year period was rated as medium. Flowering<br />

initiated in this period. Average height <strong>and</strong> collar diameter attained were 219 <strong>and</strong><br />

4.2 em respectively.<br />

(c) Average dry forage production during February, <strong>1984</strong> <strong>and</strong> November <strong>1984</strong> are<br />

given in table 25.<br />

(d)<br />

Performance of C. ciliarls among the grasses <strong>and</strong> S. hamata among the legumes<br />

was better in terms of establishment <strong>and</strong> yield. Among grass-legume mixture,<br />

C. ciliaris-s-S, hamata cornbi-ation was better than the other ones.<br />

2. Half lopping treatment at Six-monthly inter val continued to give consistent production<br />

from regenerated shoots. The ratio of fodder to fuel was found to be increased.<br />

3. Regeneration from the cut part of the stem (on complete harvesting) was not encouraging<br />

in the 2nd year also. However, such mother plants exhibited more number of<br />

healthy plantlets around them. This is an indication of the ability of the plant to<br />

exp<strong>and</strong> horizontally even if the main plant was destroyed.<br />

lI-Albizia spp. (A. amara, A. lebbek, A. procera)<br />

1. The data recorded in December <strong>1984</strong> (15 yr. old) is given in table 26.<br />

2. Lopping annually Seems to be feasible, A verage fodder <strong>and</strong> fuel production, from 6<br />

year old A. procera A. lebbek <strong>and</strong> 10 year old A. amara may be expected to be- 30.82 kg<br />

(S. K. Gupta, r. S. Pathak <strong>and</strong> R. Deb Roy)<br />

1. Acacia species.<br />

The experiment planted cn calcareous 1wastel<strong>and</strong>s with two species of Acacia viz.,<br />

A. tortilis <strong>and</strong> A. nilotica at 3 x 2 m spacing in alternate line versus alternate plant management<br />

system indicated identical response to their arrangements in terms of height <strong>and</strong> diameter<br />

growth in the first year with greater height <strong>and</strong> diameter growth for A. nilotica under<br />

both the situations. In the second year, theA. tortilis continued to give uniform growth<br />

under both the systems ef plant arrangement but A. nilotica exhibited a vide difference in its<br />

growth rate under the two plant arrangement system. Under alternate arrangement A.<br />

nilotica gave 6.2 em more height <strong>and</strong> 0.7 ern more diameter compared to alternate line<br />

arrangements. However, this year also, A. nilotica continued to exhibit more height diameter.<br />

When we compare the diameter growth of these. two species A. tortilis gave<br />

more than 2 times diameter growth than the first year while A. ! nilotica gave only 1.4 times.<br />

2. Hardwicki« binata <strong>and</strong> Dalbergia sissoo,<br />

The study on Hardwickie binat a <strong>and</strong> Dalbergia sissoo under moist, marginal wastel<strong>and</strong>s<br />

gave very poor growth under mono <strong>and</strong> mixed cultures. .N. binata gave comparatively higher<br />

survival on dry sides while D. sissoo gave it OD the moist sides. The growth parameters did not<br />

show any appreciable difference between the mono <strong>and</strong> mixed culture. However. H. binata<br />

gave higher growth in association with D. sissoo which also got benefitted by its associates.<br />

1.3 Agroforestry studies.<br />

(P. S. Pathak)<br />

(a) Effect of row orientation of leucaena leucocephla on the production of forage, fuel <strong>and</strong><br />

grain.<br />

Growth performance of wheat crop: The tillering of plants was studied under all<br />

the treatments. It was found that the maximum tillers in all the direction treatments were at<br />

the P 6oN90 dose with its peak 136Jm in N-S direction followed by NE-SE <strong>and</strong> E-W. In no<br />

tree treatments the peak was in NE-SW orientation followed by N-S. The crop height at<br />

mau.rity again showed increase with the increasing nitrogen doses with its peak 114.3 cm in<br />

N-S orientation. In the E-W orientation the variation between different nitrogen doses<br />

were very small <strong>and</strong> it ranged between 104.7 to 109.7 cm. Height in all the treatments was<br />

lowest under NW-ES direction. In the without tree sets the height was low compared to<br />

tree treatments. It was maximum in N-S <strong>and</strong> NW-ES orientation. The length of ear heads<br />

was more in without tree treatments compared to with tree ones. The peak 12 cm was in<br />

NE-SW orientation. But in the with tree treatments the peak was in E-W orientation.<br />

Production of wheat crop: The peak production under both the sets viz., with <strong>and</strong><br />

without tree was in NW ·ES orientation at P 6oN90 dose followed by N-S orientation without<br />

tree <strong>and</strong> E-W orientation with tree. The yield variability was found to be statistically significant<br />

whereby the line orientation <strong>and</strong> fertilizer treatments influenced the yield significantly.<br />

Forage production from Leucacna :<br />

Duri 19 the year Leucaena was pollarded 5 times <strong>and</strong> the total forage produced, ranged<br />

pet ween 5.8 to 9.4 tlha (dry) obtained in E-W<strong>and</strong> NW-ES orientations respectively. Half<br />

the population of trees was harvested to produce the tree density of 5000 trees/ha. The<br />

thinning produced dry firewood from 14-16.75 tJha obtained in E-·W <strong>and</strong> N-S row orientations<br />

respectively. The variations were statistically significant.<br />

Production of Cowpea <strong>and</strong> Sorghum: At the 4 fOW orientation of the alleys the trees<br />

156 )


were maintained at 2 densities viz" 5000 <strong>and</strong> 10000 tree/ha. The production in the plots<br />

without trees was more compared to that with trees with peak for Cowpea at N-S <strong>and</strong> sorghum<br />

at NE-SW orientations' The mirirnum in both the cases was in reverse order.<br />

At 5000 rrees/ha density sorghum g~ve peak production 2.34 t/ha in N-S orientation<br />

followed by NE-SW <strong>and</strong> cowpea also followed similar pattern with lower production. At<br />

10000 treesj ha density peak for both the crops was in NE-SW orientation followed by E-W<br />

orientation. The differences were found to be statistically significant.<br />

(b)<br />

Year round perennial forage based agroforestry.<br />

Durirg the year Leucaena was pollarded 4 times, guinea grass W1S harvested 7 times<br />

<strong>and</strong> berseern in the guinea grass inter rows 3 times. The forage produced during the year<br />

was 13.88, 57.19 <strong>and</strong> 37.23 t/ha respectively. During every harvest, the legume component<br />

addition in the forage improved, the quality besides adding to its per ha quantum by trapping<br />

solar energy at 2 canopy layers.<br />

(c)<br />

Leucsenz leaf manuring <strong>and</strong> yield of Oats.<br />

The experiment with Alley cropping was conducted to find out the effect of harvested<br />

tree leaves on the production of the following crop in the Alleys. In an earlier<br />

experiment it was found that the cultivation of Leuceenx improved soil fertility.<br />

The experiment hvd 5 treatment combinations viz., control, 30 kg N /ha as<br />

urea, 30 kg N /ha as dry leaf basal, 30 +30 kg/ha as dry leaf basal <strong>and</strong> top dress <strong>and</strong> 60+30<br />

kg/ha as basal <strong>and</strong> top dress The 2 cuttings of Oats were taken at 100 <strong>and</strong> 170 days after<br />

the sowing when the forage had a dry matter of 17.5 <strong>and</strong> 41.7%,<br />

The results indicated (table 27) a significant improvement in the forage yield with a<br />

highe. proportion in the lInd cutting. The differences between 30 kg N as urea <strong>and</strong> leaf<br />

were not statistically significant yet at the same dose, 5% more yield was obtained with leaf<br />

rnanurng. The other increasing doses of nitrogen as leaf equivalent gave the increment up to<br />

178 2%. where the nitrogen equivalence compared to 30 kg N as urea (100) was 153.1 indicating<br />

the use of leaf either as basal or top dress in a crop production system in agrof'oresrry.<br />

After the crop harvest the soil had a pH variation of 7.49, 7.52, 7.38, 7.43 <strong>and</strong> 7.42 respectively<br />

indicating not much fluctuation. The available nitrogen was mere in the plots applied<br />

wiih higher doses of leaf manure compared to the dose of urea or the control but with minor<br />

differences (0009,0.01, 0.011, .0011, 0.012% respectively),<br />

CUM-ENERGY PRODUCING SPECIES.<br />

5.1 Study of genetic architecture <strong>and</strong> effect of mutagens in Leuczena leucocepltala in<br />

relation to production of forags <strong>and</strong> fuel,<br />

(V. K. Gupta)<br />

1. Study of genetic variability, correlation <strong>and</strong> path coefficient analysis for forage <strong>and</strong> fuelwood<br />

yields <strong>and</strong> its components.<br />

( 158 )


path coefficient analysis of fodder <strong>and</strong> fuelwood yield per plant <strong>and</strong> other attributes<br />

were worked out. Estimates of phenotypic <strong>and</strong> genotypic correlation coefficients of 14 yield<br />

contributing characters VIZ., plant height, collar diameter, length of leaf, no. of pinnacle per<br />

leaf, length of middle pinna, no. of leaflets per pinna, length of leaflet, width of leaflet, 100­<br />

green leaves weight, no. of leaves per plant, pod length, no. of seeds per pod, 100-seed weight<br />

<strong>and</strong> seed yield, with fuelwood <strong>and</strong> fodder yield per plant showed that plant height, collar·<br />

diameter <strong>and</strong> no. of leaves per plant had significant positive association with fodder as well<br />

as fuelwood yield. Therefore, ani) these characters were used for path analysis of fodder<br />

<strong>and</strong> fuel wood yield.<br />

Results revealed that no. of leaves per plant had high magnitude of direct effect on fodder<br />

yield. Plant height <strong>and</strong> collar diameter which had significant association with fodder yield<br />

had weak negative <strong>and</strong> positive direct effects with fodder yield, respectively, In both the<br />

cases, correlation was contributed mainly by indirect effects viz., no. of leaves per plant with<br />

minor contribution via collar diameter in case of plant height <strong>and</strong> fodder yield. Indirect<br />

effect viz., no. of leaves perplant also had high amount of contribution to genetic correlation<br />

coefficient between fuelwood yield <strong>and</strong> fodder yield per plant..Therefore, emphasis should<br />

be given on the attributes like no. of leaves per plant for high fodder yield in sub-babul.<br />

The estimates of residual effect being low indicated that important fodder .yield contributing<br />

'raits were included in the present study. ..,<br />

Path coefficient analysis of fuclwood yield <strong>and</strong> other traits revealed that direct effect<br />

of fodder yield was highest followed by no. of leaves per plant <strong>and</strong> 'plant height. Collar<br />

diameter which had positive <strong>and</strong> highly significant correlation with fuelwood yield exhibited<br />

negligible effect. In this case maximum contribution was through indirect effect via fodder<br />

yield per plant followed by no. of leaves per plant <strong>and</strong> plant height. Indirect effect via no.<br />

of leaves per plant <strong>and</strong> plant height also played an important role besides direct effect in<br />

making high value of genetic correlation coefficient between fodder yield <strong>and</strong> fuelwood yield.<br />

Thus, it e.ppeared that fodder yield, no. of leaves per plant <strong>and</strong> plant height are important<br />

attributes for the fue1wood Yield. Magnitude of residual effect was also low in the path<br />

analysis of fuelwood yield <strong>and</strong> other yield contributing traits.<br />

2. Genetic analysis of forage <strong>and</strong> fuel wood yield aud their components in L. leucocephala,<br />

Observations were taken on coppiced plants of 15 crosses originated from<br />

6 Y.6 diallel, for fodder <strong>and</strong> fuelwood yield per plant. Estimates of hybrid<br />

vigour over mid parent <strong>and</strong> better parent. were worked ou~ in coPpi9~d . yields.<br />

Duration of coppice growth was 8 months. Among the parents, fodder yield <strong>and</strong> fuelwood<br />

yields ranged from-O.346 ([GFRI 29-5) to 2,091 (<strong>IGFRI</strong> 18-4) kg dry matter per plant <strong>and</strong><br />

159


2.100 (<strong>IGFRI</strong> 29.5) to 8.404 (<strong>IGFRI</strong> 18-4) kg dry matter respectively. High yields of fodder<br />

<strong>and</strong> fuelwood were observed in parents, <strong>IGFRI</strong> 18-4, <strong>IGFRI</strong> 24-1, <strong>IGFRI</strong> 25-3. Among the<br />

hybrids <strong>IGFRI</strong> 14x<strong>IGFRI</strong> 18 had maximum dry matter of 9'936 kg <strong>and</strong> 2 354 kg of fuelwood<br />

<strong>and</strong> fodder per plant respectively followed by IGFRl 14 x<strong>IGFRI</strong> 24, IGFRr 24 x<br />

<strong>IGFRI</strong> 25 <strong>and</strong> <strong>IGFRI</strong> 14 X <strong>IGFRI</strong> 25 for fuelwood yield per plant. Positive hybrid vigour<br />

over better parent was observed for <strong>IGFRI</strong> 7 X<strong>IGFRI</strong> 14 (21.87%). <strong>IGFRI</strong> 7 x <strong>IGFRI</strong> 24<br />

(35.58%),<strong>IGFRI</strong> 14xlGFRI 18 (12.56%) <strong>and</strong> IGFRl 14XIGFR[ 24 (18.02%) crosses for<br />

fodder yield. For fuelwood yield, positive <strong>and</strong> signifcant hybrid vigour was observed for<br />

<strong>IGFRI</strong> 14xIGERI 18 (18.23%), IGFRl14x<strong>IGFRI</strong> 24 (19.51%) <strong>and</strong> <strong>IGFRI</strong> 14x[GFRI 25<br />

3. Study of genetic parameters <strong>and</strong> selection of desirable plants in F 2 generation of<br />

L. leucocephala.<br />

F 2<br />

populations of 15 crosses were raised in July 1982 with their six parents <strong>and</strong> two<br />

checks (K8 <strong>and</strong> K 28). This year, two <strong>and</strong> half year old trees were harvested <strong>and</strong> observations<br />

were taken on fuelwood yield, fodder yield, plant height, collar diameter, diameter at breast<br />

height <strong>and</strong> reaction to disease. Out of IS progenies. performance of progenies of <strong>IGFRI</strong> 7 X<br />

<strong>IGFRI</strong> 14, <strong>IGFRI</strong> 7x<strong>IGFRI</strong> 18, <strong>IGFRI</strong> 7xlGFRI 24, <strong>IGFRI</strong> 14xIGFR118, <strong>IGFRI</strong> 14x<br />

<strong>IGFRI</strong> 24, <strong>IGFRI</strong> 18 x<strong>IGFRI</strong> 24 <strong>and</strong> <strong>IGFRI</strong> 18X<strong>IGFRI</strong> 25 crosses was good. Seventy<br />

eight plants were selected for raising F 3 generations in these crosses. Progenies of <strong>IGFRI</strong> 14<br />

xIGFRl 24 <strong>and</strong> <strong>IGFRI</strong> 14x<strong>IGFRI</strong> 18 were outst<strong>and</strong>ing for the above ground biomass,<br />

40, ,60, 80 <strong>and</strong> 100 kr in n08 <strong>and</strong> control, 40,60, 80, 100 <strong>and</strong> 120 kr in No.9 were planted<br />

in tpe year July 1981. Plants were harvested at the age of 3.5 years, observations were taken<br />

,Q!1 collar diameter, diameter at breast height. plant height, forage yield <strong>and</strong> fuelwood yield.<br />

NQt a single mutant was observed during experimental period. There W[1.S no significant variation<br />

among the doses in both the strains indicating that gamma rays did not have significant<br />

etrect on the growth of L. leucocephola <strong>and</strong> creation of genetic variability. However, trend in<br />

No.8 was in increasing direction with the doses while in No.9, it was in decreasing direction<br />

for collar diameter. diameter at breast height, plant height, edible dry matter, woody dry<br />

matter. Percentage of pod bearing trees reduced from 100 to 75 rn NO.8 <strong>and</strong> 80.64 to 54.05<br />

in No.9 from control to highest dose of gamma rays.<br />

5. Evaluation of the performance of hybrids <strong>and</strong> study of hybrid vigour.<br />

Twenty four hybrids <strong>and</strong> eight parents were planted in field in July 83 in two environ-<br />

The length of pod, width of pod, no. of seeds per pod <strong>and</strong> 100-seed weight ranged<br />

from 10.38 (L. macrophylla) - 24.20 (<strong>IGFRI</strong> 23-1), 1.17 (L. lanceolata) - 2.08 (L. leucocephala<br />

var K 8), 15.80 (L. shannoni) - 28.00 (<strong>IGFRI</strong> 23-1) <strong>and</strong> 1.500 (L. diiersiiolie var,<br />

strain K 156) - 4.985 (<strong>IGFRI</strong> 23-1) respectively. Flowering did not take place in L. puloerulent«,<br />

L. esculent« while in L. t richodes <strong>and</strong> L. dioersiiolie (CIAT) trees flowered but there<br />

was no seed formation.<br />

Self incornpatability was present in all the species except L. leucocephele identified<br />

based on bagging of 50 buds in each species. In L. ditersifolie: <strong>and</strong> L. lenceolet« compatable<br />

plants for pure seed production were identified.<br />

7. Evaluation of selected lines of L. leucocephala.<br />

Eighteen Selections with K8 <strong>and</strong> K28 were planted in July 1983 in irrigated area. The<br />

irrigation was given only first year for good establishment. Observations were recorded on<br />

collar diameter, diameter at breast height, plant height <strong>and</strong> disease reaction when plants were<br />

one year <strong>and</strong> six months old. Eight selections i. e. S 10 (8.00 em), S 15 (7.03 ern), S 11 (6.83<br />

ern), S 18 (6.50 ern), S 14 (6.38 cm), S 16 (6.30 em) <strong>and</strong> S 7 (6.35 ern) were better than best<br />

GENETICAL AND GENE-ENVIRONMENTAL ASPECTS IN FORAGE SEED<br />

PRODUCTION.<br />

1.1 Genetic analysis <strong>and</strong> improvement for seed yield <strong>and</strong> its components in fodder<br />

crops.<br />

(P. N. Mathur)<br />

1. Path coefficient analysis<br />

Oat: The path coefficient analysis for fodder <strong>and</strong> seed yield components was carried out<br />

by growing 34 genotypes of oat to estimate the direct <strong>and</strong> indirect effects of plant height,<br />

tilIers per plant, ·number of leaves, length <strong>and</strong> width of leaf on green fodder yield. The study also<br />

included the direct <strong>and</strong> indirect effect of length of ear head <strong>and</strong> number of spikelets on seed<br />

yield.<br />

Tillers per plant have nothing to do directly in the enhancement of green fodder yield<br />

as its direct contribuion was negative (-0.1408). There was also negative indirect effects of<br />

plant height (-0.0519), length of leaf (-0.0713) <strong>and</strong> width of leaf (-0.084) which have·<br />

masked the positive effects of number of leaves, ultimately resulting in negative association<br />

(-0.1408) of tillers per plant with green fodder yield. Number of leaves which did not show<br />

significant positive association with green fodder yield had high direct effect (0.2382).<br />

However, its contribution through plant height, length of leaf <strong>and</strong> width of leaf were low <strong>and</strong><br />

negative through tillers per plant (-0.0418), which might have resulted into a low correlation<br />

value. Width of leaf which had a high positive correlation with green fodder yield had low<br />

direct effect (0.1748) but showed high indirect effect through length of leaf (0.3131).<br />

Green fodder yield had highest positive direct effect (0.5204) on seed yield, followed<br />

hy tillers per plant (0.3177), plant height (0.3048) <strong>and</strong> width of leaf (0.1459). It was very<br />

interesting to observe that the indirect effects through green fodder yield was also highest when<br />

compared with indirect effects through other variables except for tillers per plant. The high<br />

direct effects of tillers per plant have been masked by the negative indirect effect via plant<br />

163 )


height, number of leaves, length of leaf, width of leaf <strong>and</strong> green fodder yield resulting in poor<br />

association between tillers per plant <strong>and</strong> seed yield. Number of leaves has nothing to do in<br />

the enhancement of seed yield as its direct effect is negative (-0.2214), Moreover, it also had<br />

low indirect effect through other variables.<br />

Length of earhead is otherwise a very important direct yield component having significant<br />

positive association with seed yield has negative direct effect. Length of leaf <strong>and</strong><br />

number of spikelets per plant had high indirect effects through green fodder yield <strong>and</strong> plant<br />

height than their direct effects on seed yield. On the other h<strong>and</strong>, plant height had high<br />

direct effects on seed yield than it" indirect effect through number of leaves <strong>and</strong> number of<br />

spikelets.<br />

It was therefore, evident that plant height, length of leaf <strong>and</strong> width of leaf were the direct<br />

components both for fodder <strong>and</strong> seed yield for which selection can be effective as these components<br />

also exhibited hight heritability coupled. with high genetic advance. While selecting<br />

high yielding genotypes for fodder as well as seed yield in oat, a compromise must be<br />

reached so that advance in one component is not nullified by another.<br />

Cowpea: Path coefficient analysis was done to estimate the direct <strong>and</strong> indirect effects<br />

of branches per plant, leaves per plant, pod bunches per plant, flowers per bunch <strong>and</strong> pods<br />

Fer bunch 0'1 seed yield The analysis indicated that pods per bunch had the maximum direct<br />

effect on seed yield followed by pod bunch per plant.<br />

Branches Fer plant had positive correlation with seed yield while its direct effect was negative.<br />

Its positive indirect effect through pod bunches per plant <strong>and</strong> pods per bunch were<br />

perhr ps the major artifact of this positive association. It clearly indicates that as the number<br />

of branches increases, total number of pods per plant; will also increase because of the<br />

increased number of pod bearing branches. The direct effect of the leaves per plant was<br />

low compared to its ind irect effect through branches per bunch. It had 'negative indirect<br />

effect through branches per plant <strong>and</strong> flowers per bunch Hence, it would be rewarding to<br />

lay stress on pod bunches per plant. This can be achieved through increased number of pod<br />

bearing branches in selection programme in fodder cowpea.<br />

2. Breeding high fodder yielding varieties of photo-period sensitive bajra.<br />

Two composites PST-899 <strong>and</strong> PSL-2151 which bompleted five cycles of selection were<br />

put underpreliminary yield trial. The data on yield trial revealed that these two composites<br />

are superior over giant bajra, Rajko <strong>and</strong> L-74, checks.<br />

1st position across 13 locations <strong>and</strong> was identified as a promising variety to be released by the<br />

Forage Workshop. This composite was prepared after allowing the r<strong>and</strong>om mating among the<br />

ten lines for 4 generations. The important morphological features of the variety were as<br />

follows:<br />

(a) The duration of flower initiation to complete flowering was very large <strong>and</strong> hence late<br />

maturity.<br />

(b)<br />

(c)<br />

(d)<br />

Dark green foliage even at seed maturity.<br />

Small ear head.<br />

High tillering with long leaves.<br />

(e) The basal internodes were very short which produced more number of leaves in the<br />

lower half of the plant.<br />

Twenty hybrids along with their parents were raised during kharif <strong>1984</strong> <strong>and</strong> data were<br />

recorded for various development traits. Some of the hybrids viz., SP-I4 x Giant bajra, SP-63<br />

x Giant bajra, SP-66 X Giant bajra, SP-I8 X Rajko, SP-50 X Rajko <strong>and</strong> SP-82 X Rajko showed<br />

good performance.<br />

INVESTIGATIONS ON AGRONOMIC AND PHYSIOLOGICAL ASPECTS IN<br />

FORAGE SEED PRODUCTION.<br />

2.1 Maximization of Seed production in pasture <strong>and</strong> forage plants with the amelioration<br />

of agronomic practices of cultivation.<br />

(R. P. Singh)<br />

1. Cowpea: Varietal seed setting potentiality-s-Twelve promising strains of cowpea<br />

were evaluated for seed yield components <strong>and</strong> seed yield, The results showed the yield potential<br />

in the order of NP-3 (3.12 q!ha);> UPC 5286 (2.52 q!ha» <strong>IGFRI</strong>-S-450 (2.4 q!ha» HFC<br />

42-1 (1.43 q!ha) <strong>and</strong> least in Russian Giant (0.8 q!ha).<br />

The observations on seed setting characters lead to the conclusion that in the agroclimatic<br />

conditions of Bundelkh<strong>and</strong> the maturity duration of a varietyis an important character<br />

which influences seed yield <strong>and</strong> as such medium duration varieties were found superior over<br />

late duration varieties. It was observed that number of flower retained, number of pod, number<br />

165 )


of seed/pod <strong>and</strong> test weight were positively correlated with the seed yielding potentiality of<br />

the cultivar. It was further noted that the flowering to maturity period falling between<br />

September 15 to November 15 was the most suitable for high seed setting in a cultivar.<br />

Seed production potentiality of cultivars under summer <strong>and</strong> kharif sowing conditions.<br />

The seed of three promising c.rltiv.rrs (NP-3, HFC 42-1 aad Russian Giant) were sown on 4<br />

dates in spring/summer (February 25, Malch 10 <strong>and</strong> 25 <strong>and</strong> April 10) <strong>and</strong> kharif (June 25,<br />

July 10, 25 <strong>and</strong> August 10) at row spacing of 30 em <strong>and</strong> seed rate of 30 kg/ha. Uniform<br />

fertilizer application W.1S made with 15 kg N, 30 kg P 20j <strong>and</strong> 30 k~ K 20/ha.<br />

On the basis of the results the following conclusions could be derived :<br />

(i) The seed production potentiality of some of the cultivars in summer is lzss than as<br />

compared to kharif season. The important limiting constraints which prevailed in<br />

summer seed production were thinner plant population, flower <strong>and</strong> pod drops. Similarly<br />

the pods were not properly filled (3-4 as against 7-8).<br />

(ii)<br />

In spring. sowing in March was found critical as the later sown crop did not flower <strong>and</strong><br />

the earlier sown one was severely affected by Jassids <strong>and</strong> remained patchy in st<strong>and</strong>.<br />

Russian Giant did not flower <strong>and</strong> NP-3 <strong>and</strong> HFC 42-1 produced only 1.5 <strong>and</strong> 1 q<br />

seed/ha, respectively.<br />

(iii) The crop Sown on June 25 <strong>and</strong> July 10 encountered Severe weed infestation<br />

(S20-11l2/m 2 ) ard grEw vegetatively more bulky at the expense of reproductivejphase,<br />

On the contrary, the crop sown on July 25 or August 10 was less infested with weeds,<br />

attained balanced canopy <strong>and</strong> diverted more energy towards pod production. Under<br />

these sowing dates the reproductive period approached at the proper vegetative growth<br />

'evel ", hich terminated in profuse pod formation <strong>and</strong> seed development. The average<br />

yields were 1.52, 2.27, 3.46 <strong>and</strong> 3.36 q/h'l with corresponding dates of sowings. The<br />

maximum yield was obtained from NP-3 <strong>and</strong> the minimum with Russian Giant.<br />

2. <strong>Fodder</strong> Sorghum (Rio)<br />

Split application of 80 kg N/ha at sowing <strong>and</strong> side-dressing at knee-high stage (1/2+<br />

1/2) doubled (12.25 q/ha) the seed production as compared to broadcasting of dose at sowing.<br />

Broadcastmg of full nitrogen at knee-high stage was at par with split (1/2+1/2) application.<br />

It was interesting to note tha: atleast one application in the roorzone (either at sowing or at<br />

knee-high stage) was very beneficial. Three splitting (1/3+ 1/3+ 1/3) at sowing, knee high<br />

stage <strong>and</strong> flag leaf stage was not necessary.<br />

3. Berseern<br />

Seed setting behaviour of cultivars-s-Seven promising strains of berseem (Wardan,<br />

BL-·l, JB-2, JB-l, UPB-I0l, UPB-1.02 <strong>and</strong> Mescavi) were evaluated under two phosphate<br />

levels. The seed yield was the maximum in Wardan (2.01 qjha) followed by M escavi (1.80<br />

qjha) <strong>and</strong> minimum in JB-2 <strong>and</strong> BL-l. The dry fodder yield was also highest in Wardhan<br />

(40.5 qjha) followed by Mescavi (41 qjha). The analysis of the plant characters showed<br />

positive correlation coefficient values of flower number (r=+0.777), number of seedjplant<br />

(r=+0.844), seed weight (r=+0'747) <strong>and</strong> number of tillers (r=+0.579). Plant height<br />

showed negative correlation, Application of 50 kg P 20,j/ha increased fodder as well as seed<br />

yield over 30 kg P 20:;jha.<br />

Effect of height of last cutting on berseem seed production : The treatment consisted<br />

of three cutting heights (of the time of leaving the crop for seed production) <strong>and</strong> foliar spray<br />

ofatrazine at 0 <strong>and</strong> 0.1% concentration (after 15 days of regrowth),<br />

The results revealed the superiority of berseem crop which was cut at 10 em height<br />

before leaving it for seed production (IS a result of better gradient of sugar concentration <strong>and</strong><br />

transport to active site (Table 28). This treatment also increased the boll number as well "s<br />

the number of seed per boll. Atrazine spray at a concentration of 0.1% a. i. was found<br />

effective in improving number of bolls, number of seed per boll <strong>and</strong> seed size. A cutting<br />

height of 10 em superimposed with atrazine spray produced the maximum seed yield.<br />

2. Effect of N<strong>and</strong> P on seed production of pennisetum polystacltyon.<br />

The experiment was repeated in the second year with five levels of nitrogen (0, 30, 60,<br />

90 <strong>and</strong> 120 kg Njha) <strong>and</strong> three levels of phosphorus (0, 30 <strong>and</strong> 60 kg P20s/ha) to select the<br />

optimum dose of fertilizers for cbraining the maximum seed yield of this grass.<br />

The result revealed that the seed yields with 80 <strong>and</strong> 120 kg N/ha were practically the<br />

same (l44 kgjha) seed yield (111.49 kg/hal was obtained III the control (no nitrogen)<br />

The seed yields of 136.38 <strong>and</strong> 135.66 kg/Ila obtained with 30 <strong>and</strong> 60 kg P 205/ha<br />

respectively were at par.<br />

3. Effect of inter <strong>and</strong> intra-row spacing on seed production in grasses.<br />

{i) Setaria sphacelate : The treatments consisted or ten treatment combinations<br />

with four inter <strong>and</strong> intra spacings of 75, 50, 30 <strong>and</strong> 15 em on S. sphacelata cv. n<strong>and</strong>i. A fertilizer<br />

schedule of 40 kg Njha <strong>and</strong> 20 kg P205/ha was applied at planting time in the middle \<br />

of July to all the plots.<br />

The maximum seed yield (68.85 kg/hal was obtained with a spacing of 50 sm X 30 cm<br />

<strong>and</strong> the minimum (22.64 kg/hal with a spacing of 75 ern X 75 em.<br />

o (ii) Chrysopogon fuluus: The experiment on inter <strong>and</strong> intra-row spacing was laid<br />

out on Chrysopogon fulvus cv. Mhow <strong>and</strong> Ch<strong>and</strong>igarh to know the best spacing for getting<br />

the maximum seed yield. The treatments were the same. as for Setaria species. Nitrogen @<br />

40 kg/ha was applied in the middle of July uniformly to all the plots.<br />

Results showed that the maximum seed yieid (41.85 kg/ha) was obtaided in the spacing<br />

of 50 em X 30 em followed by 30 em X 30 (37.41 kg/hal <strong>and</strong> 50 em X 50 em (3422 kg/hal<br />

in Chrysopogon [ultus cv. Mohw. The minimum seed yield (15.95 kg/ha) was obtained<br />

with a spacing of 75 em X 75 COl.<br />

( 169 )


As regards Chrysopogon fulous cv. Ch<strong>and</strong>igarh, the maximum seed yield (80.70 kgjha)<br />

was obtained with the spacing of 50 em X 50 em followed by 50 em X 30 em <strong>and</strong> 75 em x l S<br />

em (78 kg/ha). The minimum seed yield was obtained in narrow spacing of 15 cmx 15 ern,<br />

4. Effect of spacing <strong>and</strong> seed'rates on seed production in glasses Setaria sphecelat a.<br />

An experiment with three row to row spacings t25. 50 <strong>and</strong> 75 em) was estnb lished<br />

during the year using five seed rates (2.5, 5.0, 7.5. 10.0 <strong>and</strong> 12.5 kg/ha).<br />

During the establishment year, the results did not show significant differences among<br />

seed rates <strong>and</strong> spacings. However, maximum seed yield 03.32 kg/ha) was obtained with<br />

the spacing of 50 cm followed by 75 <strong>and</strong> 25 ern row to row spacing (12 kg!ha). Maximum<br />

seed yield of 12.53 kg!ha obtained with a seed rate of 7.5 kgjha was at par with 5.0 kg<br />

seed/ha. Minimum seed yield (11.42 kgjha) was, however, obtained with a seed rate of<br />

2.5 kgrha.<br />

5. Pasture plants<br />

Ten entries of Cenchrus <strong>and</strong> nine of other grasses iPaspalum, Panicum, Setaria, Chrysopogon,<br />

Dichanthium, Guinea & Brachiaria were planted to study their seed setting behaviour<br />

<strong>and</strong> yielding potentiality. The seed yielding potentiality was found in the descending order<br />

of Cenchrus ciliaris CV, Biloelars: Paspalum plicatulum> Cenchrus-black local> Panicum<br />

2.3 Agronomical studies for exploiting system based seed production in forage crops<br />

(cultivated).<br />

(R. K. P<strong>and</strong>ey)<br />

1 . Evaluation of crop cultivation systems for improved seed production in Oat varrety<br />

3021.<br />

Experiment consisted of eight variable systems including six treatments of 40 days cut<br />

crop. After fodder cut, crop recieved 40 kg N /ha in one <strong>and</strong> two equal splits (at cut <strong>and</strong> 40<br />

days later) with <strong>and</strong> without inter-row-tillage <strong>and</strong> placement of 50 kg P205/ha. Rest two<br />

treatments were of uncut crop, one of which was sown 40 days later coinciding with fodder<br />

cut in early sown crop. Both these st<strong>and</strong>s received 40 kg N/ha as top dressing. A common<br />

dose of 60 kg N<strong>and</strong> 50 kg P205/ha was applied as basal fertilizer schedule to all the treatments,<br />

The cultivation system comprising 40 days cut crop receivmg 40 kg N /ha in cornbinanation<br />

with inter-row tillage <strong>and</strong> placement of 50 kg P205/ha was found to be more promising.<br />

This system recorded an additional yield of 70.0 q green fodder <strong>and</strong> 2.34 q seeds/ha<br />

over that obtained from uncut crop applied with the same level of nitrogen. The dif'erence<br />

between these treatments was statistically significant. The split application of nitrogen after<br />

cut did not show significant rasponse to seed crop.<br />

2. Evaluation of mixed cropping systems of fodder sorghum <strong>and</strong> cowpea for improved<br />

seed production.<br />

In all, eight treatments were tried, Cowpea, cv. HFC 42-1 was introduced in 50 em<br />

apart rows of sorghum cv, M. P. Chari by broadcasting 10 to 20 kg seed/ha. In case of line<br />

sowing 20 kg sed of cowpea was harvested for fodder in the mid of the Season while in the<br />

other, the crop was maintained for seed. For comparison, pure crops of sorghum <strong>and</strong> cowpea<br />

were also grown at 25 <strong>and</strong> 50 cm spacings' In closer spacing, 50 <strong>and</strong> 40 kg seedj ha<br />

were USed for cereal <strong>and</strong> legume. respectively which were reduced to their halves under wider<br />

spacing. 1:-,,,<br />

171


None of the crop mixtures reduced the seed yield of sorghum (MP Chari) significantly.<br />

In pure culture crops, 50 cm row spacing produced higher seed yield over 25 em spacing. In<br />

mixed cropping system, broadcast cowpea (20 kg seed/ha) produced an additional seed yield<br />

of 2.55 qjha without significant reduction in the seed production of 50 ern apart sorghum.<br />

Similarly, an additional green fodder yield of 78.4 q/ha was obtained from cowpea when<br />

grown with sorghum in alternate rows.<br />

2.4 Studies on phosphorus <strong>and</strong> boron in cowpea, berseem <strong>and</strong> luzerne seed crops.<br />

(S. M. Mishra)<br />

1. Studies on phosphorus nutrition, on its uptake, use efficiency pattern <strong>and</strong> sugar synthesis<br />

in lucerne (Medicago sativa L.).<br />

A field experiment with five levels of P205 (0, 20, 40, 60 <strong>and</strong>80 kg/hal was conducted<br />

-on s<strong>and</strong>y loam soil to study the uptake behaviour of P <strong>and</strong> its proportionate availability to<br />

lucerne from two surces viz., native <strong>and</strong> fertilizer. The result revealed that the translocation<br />

-of water soluble sugars to seeds during reproductive- phase was found to be associated with P<br />

uptake. Lucerne crop, in which several cuttings are taken before the crop is left for seed,<br />

depends for its P requirement mainly on native source.<br />

2. Yield, phosphorus removal <strong>and</strong> its USe efficiency by cowpea as affected by rateof P<br />

applications.<br />

A field experiment with 5 levels of P 2 0 5 (0, 15.. 30, 45 <strong>and</strong> 60 kg/ha) was conducted on<br />

.red soil to study the P response, removal <strong>and</strong> USe efficiency by cowpea var. HFC 42-1.<br />

Increased yields <strong>and</strong> higher P concentrations were oberved for straw, pod covers <strong>and</strong> seeds<br />

'with increasing P levels. The fertilizer efficiency was found to be only 13.75 pereent indicating<br />

high P fixing capacity of these soils.<br />

2.5 Physiological variability in forage crops <strong>and</strong> their manipulation for high seed<br />

yield.<br />

(N. C. Sinha)<br />

1. Physiological variability <strong>and</strong> source - sink relationship in guar (cluster bean).<br />

Source-sink relationship, among eight varieties of cluster bein were studied Cfable 3J).<br />

In general, sugar concentration was maximum in flower (7.5%) followed b) root (7.2%), leaf<br />

172 )


(5;7%) <strong>and</strong> stem (5.7%). The high seed yield in varieties GL-~, Guar .80 <strong>and</strong> GL-12 may be<br />

correlated with higher sugar concentration in flower, ef1iclent functioning of photosynthetic<br />

pigments (as judged by Chla. Chlb) <strong>and</strong> moderate respiratory balance at anthesis stage of crop<br />

growth. Variety GL 14 stood next in seed production. In this variety most of the sugar was<br />

translocated from leaf to seed directly; even though the sugar cancentration was poor in flower.<br />

Extremely high respiration rate of HFG 119 resulted in poor concentration of sugar in all the<br />

plant parts<strong>and</strong> thereby adversely affected the seed formation though this variety had high<br />

chlorophyll. Moreover, low dark respiration in variety GL 18 <strong>and</strong> GL 16 did not favour<br />

the seed yield because of poor translocation of sugar from leaf to stem to seed. Thus it may<br />

be concluded that moderate dark respiration <strong>and</strong> good accumulation of sugar in flower appeared<br />

to be desirable characters for high seed harvest in cluster bean.<br />

2. Source-Sink relationship studies in bajra,<br />

A field experiment was conducted with seven varieties of bajra (PSB 2, PSB 3, WCC-<br />

75, Gujarat selection, Ar:<strong>and</strong> selection, JFB 801 <strong>and</strong> BJ 104) to analyse their yielding ability.<br />

Seed production was higher in moderate tillering varieties i. ~. WCC~75 <strong>and</strong> Gujarat selection<br />

173 )


ut fodder yield was highest in JFB 801. Gujarat selection appeared to be dual purpose<br />

since this variety produced enough fodder besides yielding maximum seeds. It may be worth<br />

while to mention that poor <strong>and</strong> high tillering did not appear to be conducive for forage <strong>and</strong><br />

seed production, respectively.<br />

The sugar concentration was low upto jointing stage <strong>and</strong> increased sharply at anthesis,<br />

with sudden fall at postanthesis period. Among the plant parts, stem showed the highest<br />

concentration indicating that it serves as reservoir for sugar accumulation. Sharp decline<br />

in sugar content in leaf from anthesis to post anthesis period indicated rapid translocation<br />

of sugar (newly formed photosynthatesj towards stem <strong>and</strong> its further utilization in cob formation.<br />

Heavy unloading of sugar from leaves during that period adversely affected photosynthetic<br />

process. The majur difference in sugar content during anthesis period appeared to<br />

favou r the grain growth <strong>and</strong> development in variety WCC-75. The concentration of sugar<br />

was intially high in JFB 801 which increased gradually at anthesis with 'little fall at post<br />

anthesis period. The data revealed that high sugar content in the begining was favourable for<br />

increased forage production <strong>and</strong> has comparatively less contribution to cob formation.<br />

3. To study the effect of chemicals on water soluble sugar <strong>and</strong> seed yield of berseem,<br />

A field experiment was conducted to study the effect of chemicals (Sulpur- 15, 30, 45<br />

<strong>and</strong> 75 gjlitre, planofix 0.2 <strong>and</strong> 0.4%. Borax 2 <strong>and</strong> 4 gjlitre. ammonium molybdata-3 <strong>and</strong> 6<br />

gjlitre, potassium chloride 10 <strong>and</strong> 20 gjlitre), on the concentration of water soluble sugar<br />

reflecting in seed yield of berseem. Application of potassium chloride @ 10 gjlitre showed<br />

higher (3-4 times) increase in seed yield over control which might be due to higher concentration<br />

of water soluble sugar in leaf <strong>and</strong> flower. There is also indication that K +is greatly<br />

associa-ed with translocation of sugar from storage organs to reproductive organs. The<br />

higher content of sugar in leaf due to application of KCl revealed the involvement of Kin<br />

photosynthate formation <strong>and</strong> their use in tiller development, Planofix (0.2%) also increased<br />

the seed yield equivalent to KCI treatment though the mode of action may have been different.<br />

The increased seed yield due to Borax (4 gjlitre) mignt be related with higher sugar content<br />

in flower responsible for seed <strong>and</strong> boll formation. Tulering was not influenced by Borax<br />

application. The increase in seed yield due to ammonium molybdate was sightly lower than<br />

Borax application <strong>and</strong> appeared to be related with utilization of sugar in boll <strong>and</strong> seed formation<br />

as the sugar concentration waS quite evident in flower. Application of sulphur was not<br />

effective in influencing the seed yield of berseem; though higher dose showed some stimulatory<br />

effect on seed attributes.<br />

4. Effect of seed size on germination, seed vigour <strong>and</strong> physiological potential of cowpea<br />

(Vigna unquiculata)<br />

(N. C. Sinha & R. P. Singh)<br />

174 )


Four varieties of cowpea (Russian Giant, UPC 5286, JC 21 <strong>and</strong> GFC 3) were graded<br />

into three size groups from mixed lot of 500 g seeds viz., Large (retained over mesh No, 4<br />

of 4.0 mm squares) medium (retained over mesh No. 5 of 3.35 mm squares) <strong>and</strong> (small through<br />

mesh No.5) alongwith mixed seed as control.<br />

After gradation, the seeds were germinated under controlled condition with a view 10<br />

screening out the varieties bearing good vigour potential to yield good bulk cf forage/plant,<br />

The experiment was conducted at 20 ± lOC'<br />

Cowpea cultivars Russian Giant <strong>and</strong> UPC 5286 showed high ratio of large seeds in<br />

mixed lot. Only these two cultivars exhibited cent per cent germination with potential vigour<br />

<strong>and</strong> high germination energy index. In addition, the large seeds had high germination percentage<br />

over other group without influencing the germination energy index. Seed vigour (as determined<br />

by shoot length, shoot ,: root. ratio <strong>and</strong> dry matter accumulation) was high in large<br />

sized seed followed by medium ones. Water soluble sugar was high with less production of<br />

alcohals in large seeds resulting in relatively high ratio of sugar : alcohal while<br />

it was reverse in small seeds.<br />

5. Studies on Vigour aud viability of fodder seeds under uncontrolled storage condition.<br />

.q.f..~ :.<br />

Seeds of cowpea Vigna unguiculata L. var. HFC 42-1), sorghum (Sorghum bicolor var.<br />

M. P. Chari) <strong>and</strong> Berseern (Trifolium alex<strong>and</strong>rium L. var. Wardhan) were stored in bags!<br />

containers (Polythene-P, Do-SutIi-Do, Markeen-M, gunny bagt-ST <strong>and</strong> seed box-SB) af er<br />

drying in sun for 2-3 days. Similar samples from different stores were taken to study the<br />

effect of storage containers on germination, seed vigour <strong>and</strong> physiological health after 4, 17<br />

<strong>and</strong> 26 weeks, Gradual loss on seed vigour <strong>and</strong> physiological potential occurred during<br />

storage; being minimum with cowpea seed stored in polythene (p) <strong>and</strong> Markeen (n) <strong>and</strong> M.P.<br />

Chari in Do Sutli (Do). The vigour <strong>and</strong> germination of berseem seed were initially poor<br />

(4 week storage) but gradually improved during 26 weeks storage. There was no effect of<br />

storage container on berseeru'seed vigour <strong>and</strong> showed an indication of after ripening phenomenon<br />

in it.<br />

-medium maturing <strong>and</strong> 76-103 late maturing) in split plot design replicated three times. The<br />

results revealed that the crop sown on November 3 had minimum incidence of mustard saw<br />

fly (1.409 larvaejm'') followed by October 13 sown crop whereas minimum popuhtion of<br />

mustard aphid was observed in the crop sown on October 23 (5.968 per twig of 4 em).<br />

Maximum green fodder (227.8 qjha) <strong>and</strong> seed (11.4


susceptible variety (EC-4216), two weedings (after 15 <strong>and</strong> 30 days of sowing) <strong>and</strong> balanced<br />

fertilizer schedule (15 kg N+60 kg P205+20 kg K 2 0 jha, can minimise the incidence of<br />

insect-pests can give higher seed yield over conventional cultural practices (late sowing, local<br />

variety-<strong>and</strong> no fertilizer).<br />

By integration the improved cultural practices with insecticide endosulfan,.-0.08% ai<br />

(being applied at 50 days of crop growth, the incidence of pests was further reduced, <strong>and</strong> seed<br />

production was increased.<br />

5. Efficacy of different insecticides <strong>and</strong> their frqeuencies of application for the control of<br />

insect-pest complex of c.)wpea in inter cropping system (With M. P. Chari).<br />

A replicated trial was conducted with insecticides endosulfan 35 EC (0.08% a. 'i.),<br />

Carbaryl 50 w. p. (0.1 % 11''i.), monocrotophos (0.06% a i.) <strong>and</strong> malathion 50 EC (0.05%) in<br />

two frequencies (once at 55 dsys <strong>and</strong> twice at 45 <strong>and</strong> 60 days of crop growth) to see their<br />

effectiveness against insect-pests of vegetative stage when the cowpea crop was intercropped<br />

with M. P. Chari. The results indicated that the crop sprayed only once either with endosulfan<br />

(0.08% a. L) or carbaryl (0.1% a. i.) gave satisfactory control of leaf-hoppers, defoliators,<br />

blister beetle <strong>and</strong> lycaenid butterfly <strong>and</strong> produced maximum seed yield (10.0 qjha) as<br />

compared to control (5.9 qjha).<br />

6 Screening of promising cowpea varieties' agai nst its major insect-pests for seed prodiction<br />

potentiality.<br />

Twenty one varieties of cowpa were sown in a replicated trial to study the resistance<br />

against major insect-pests like leaf-hopper, defoliators, blister beetle <strong>and</strong> lycaenid butterfly:<br />

The results showed that varieties lL-89, IL-132, IL-307 <strong>and</strong> <strong>IGFRI</strong>-450 were comparatively<br />

least susceptible to insect pests <strong>and</strong> gave higher seed of 11.7, 11.3, 10.9 <strong>and</strong><br />

10.4 qjha respectively.<br />

3.2 Seed borne diseases <strong>and</strong> their control in forage crops.<br />

(S. N. Singh)<br />

1. Isolation <strong>and</strong> identification of different micro-organism associated with forage crops.<br />

Safflower (Carthamus tinctorusy : Mecrophomimi phsseoline, Alternaria csrthemi,<br />

Aspergillus {favus, Drechslera spp., Scletotium roltsii, Fusartum monillforme, Collectot richum<br />

177 )


earthami <strong>and</strong> Rhizopus nigricuns were found dominant seed pathogens in all cultivars <strong>and</strong><br />

resulted in seed rot <strong>and</strong> seedling mortality. Mecrophomina phaseolina <strong>and</strong> Sclerotium rot/sit<br />

were found severe seed-borne pathogens allowing only 15-20% seedlings to emerge.<br />

Stylosanthes species: Seeds of S. hamata, S. humilis, S. scabra, <strong>and</strong> S. »iscosa<br />

were collected from different locations. Planting of seed component showed Phoma spp.<br />

Curoularia lunata, Fusarium monilitorme, Collectotrichum glocosperioides <strong>and</strong> Drechsera spp.<br />

as seed associated pathogens, out of which Colletotrich urn glocosperioides <strong>and</strong> Curvularia<br />

lunata were found in all species. These affected germination <strong>and</strong> seedling growth. The incidence<br />

ranged from 8 to 82.5% in S. humilis <strong>and</strong> S. hamata..<br />

') "<br />

Evaluation of fungicides for controlling seed-borne diseases.<br />

Berseem & Lucerne: Soaking treatment with Bavistin @ 0.75% for 24 hours gave the<br />

best seedling emergence in berseem wardhan <strong>and</strong> Lucerne <strong>IGFRI</strong>-S-244 with drying at room<br />

tern peratu re.<br />

Anthracnose in Stylosanthes : During first year the trial was conducted on S. hamata,<br />

S. humilis, S. scabra <strong>and</strong> S. uiscosa after Seed treatment with Bavistin <strong>and</strong> Vitavax @ 0.3%<br />

to prevent the introduction of new races of Collectorichum glocosporioides <strong>and</strong> to limit the<br />

spread Of infection in fields. In all the species Bavistin was quite effective in reducing the<br />

seedling diseases <strong>and</strong> seed rots upto 30%. S. hamata <strong>and</strong> S. humilis species responded more<br />

to this treatment than S. scabra <strong>and</strong> S. »iscosa.<br />

Testing of proven results: Best fungicides viz. Bavistine @ 0.25~~ <strong>and</strong> Dithane Z-78<br />

were tested. The pre-emergence mortality due to Maerophomina phaseolina, Fusarium<br />

semitectum <strong>and</strong> F. equiseti was only 5-10% with the treatments against 25-38% in control.<br />

The growth <strong>and</strong> seed yield was maximum in Bavistin treatment.<br />

Lucerne (<strong>IGFRI</strong>-S-244) <strong>and</strong> Berseei.r (Wardhan). The fungicides Dithane M.45,<br />

Vitavax, Benlate, Brassicol, Thirarn, Bavistin, Dithane Z-78 <strong>and</strong> csres<strong>and</strong>ry @ 0.25% ~were<br />

applied as a seed dressing before sowing against root rot (Fusarium oxysporum) in lucerne.<br />

Bavistin <strong>and</strong> vitavax @ 0.25% treatments checked the disease to the extent of 92% These<br />

fungicides also checked downy mildew (Peronospora trifoliorum) <strong>and</strong> leaf rust Uromyces<br />

striatus, Bavistin <strong>and</strong> Vitavax treatments significantly increased green forage <strong>and</strong> seed yield by<br />

35-58% <strong>and</strong> 48-68%, respectively.<br />

Diseases,' Earlier observation in berseern crop showed the effect of pre-emergence <strong>and</strong> ­<br />

post-em~rgence damping-off (caused by seed-borne pathogen Fusarium-oxysporum, Curoaula<br />

178 )


ia lunata <strong>and</strong> pythium rot: There was significant decrease in the number of seed per boll,<br />

test weght <strong>and</strong> ultimately the seed yield. The maximum loss in plant population was recorded<br />

in non-treated seeds while least in fungicides treated plots despite low infection. Wilt<br />

(F. oxysporum) <strong>and</strong> seed rots cause considerable reduction in yield. The mortality ranged<br />

from 15-32% in sick non-treated plots. The treatment u-ith Thiram <strong>and</strong> Bavistin @ 0.25%<br />

improved the plant population by 30-58% <strong>and</strong> seed yield by 48-73%.<br />

3. To device suitable measures for maintenance of seed health during storage.<br />

Cowpea seed: Among the fungisides tested during the year by 1STA method,<br />

Dithane Z-78 <strong>and</strong> Thirarn @ 0.25% proved to be the best in eliminating the Mncmphomina<br />

phaseolina <strong>and</strong> Fusarium fopp. These fungicides proved to be an excellent for term storage<br />

with good germination <strong>and</strong> planting value in fields when Kcpt in laboratory after required<br />

m, c. drying temperature in sealed containers.<br />

Berseern <strong>and</strong> Lucerne seeds: In the test for storage, these eeeds were kept at 20-25 0 C<br />

with 30-45% R. H. in CaO <strong>and</strong> Cacl 2 treatments. Eleven percent m. c. gave more germination<br />

during long-term storage of one year.<br />

Eleven germ plasm of Carthamus aphid (Macrosiphum sonchi). Mid January onwards<br />

the aphid population started building-up: Within a fortnight period, it assumed dangerous<br />

proportions covering entire plant, right from base to the top. The population was kept under<br />

continuous conservation, based upon which different gerrnplasrns with accession numbers stood<br />

in the following tolerance order.<br />

130>118>74>96>20>117>9>1>116>7>95.<br />

3.4 Toxicological studies in relation to insect pests of fodder crops.<br />

Under this project various new insecticides were tried against the insect pests in search<br />

of t~e promising ones, which could be included in the programme to determine their residual<br />

persistance.<br />

Promising insecticides for safflower aphid Eleven gerrnplasms of Carthamus were<br />

sprayed with higher dose of monocrotophos (0'08%) at 60 days of growth when heavily<br />

infested with Carthamus aphid. Macrosiphum sonchi (aphid population of 76-300 jtwig!plant.<br />

The insecticidal treatment almost whiped out the aphid population, knocking them down on<br />

the gr~)lind, It provided complate safety to the plant from the pest for a fortnight. However,<br />

the population build-UP started again within a week's period. At this stage, the second<br />

treatment of monocrotophos (0.08~;';) was given to the crop, It repeated its earlier performance.<br />

The third spray of the insecticide was however, needed a fortnight later.<br />

Thus three insecticidal sprays (monocrotophos at 0.08%) at 20 days interval starting<br />

from 60 days of growth needed to keep the crop free from aphids.<br />

Investigations to evaluate histochemical technique vis-a-vis other procedures:<br />

(L. K. Karnani)<br />

The samples of 6 grass species, viz. C. ciliaris, C. sitigerus, D. annulatum,<br />

S. nertosum, H. cont ortus <strong>and</strong> I. wightii were collected from the C. R. Farm at an interval<br />

of one month from August to October, <strong>1984</strong>. The samples were collected in triplicate. Two<br />

samples were oven dried at a temp of 600C <strong>and</strong> the dry matter was caculated. The third<br />

sample was kept for histochemical studies.<br />

Histochemical studies: The plant was divided into four parts, namely, leaf blade, leaf<br />

sheath, top stem <strong>and</strong> bottom stem. Thin sections of all the plant parts were cut <strong>and</strong> stained<br />

with acid phluoroglucinol <strong>and</strong> chlorine-sulphite.Microscopical examination showed that in leaf<br />

blade, lignified tissue stained with acid phluoroglucinol was observed in the inner bundle<br />

sheeth <strong>and</strong> xylem of the large vascular bundle, while the sclerenchyrna got stained with<br />

chlorine sulphite.<br />

In leaf sheath, lignified tissue stained with acid phluoroglucinol was found mostly in<br />

small layers around phloem <strong>and</strong> xylem of the vascular bundles. The sclerenchyma connecting<br />

the bundles to the epidermis was stained slightly with acid phluoroglucinol but more so with<br />

chlorine sulphite. The sclerenchyma cells at the adaxial side were stained with chlorine<br />

sulphite. Parenchyma bundle sheaths surrounded vascular bundles <strong>and</strong> mesophyll in between<br />

the epidermises.<br />

In the stem portion, lignified tissue in the epidermis <strong>and</strong> in a thick b<strong>and</strong> of sclerenchyma<br />

<strong>and</strong> vascular bundles stained positive with acid-phluoroglucinol. Parenchyma cells stain<br />

positive for lignin with chlorine-sulphite only after keeping for some time. The variation in<br />

the distribution of lignified tissues in different portions studied is very significant <strong>and</strong> reflects<br />

the nutritional value.<br />

181


In another experiment, 5 mm sections of the plan t parts were cut <strong>and</strong> incubated with<br />

cuffer solutions alone (control) <strong>and</strong> with stained rumen liquor for 72 hours. The sections<br />

were thoroughly washed with distilled water <strong>and</strong> studied histochemically. These histochemical<br />

studies undertaken in conjuction with other nutritional techniques would facilitate rapid<br />

screening of forage samples <strong>and</strong> avoids tedius animal experiments.<br />

1.2 Invitro studies on the digcstibi ity of important fodder <strong>and</strong> fot agIO crops.<br />

(S. C. Gupta)<br />

1. Prediction of IVTDMD values using simple laboratory analyses data.<br />

Detailed investigation were undertaken to develop simple multiple regression equations<br />

for the prediction of IVTDMD at appropriate stage were used in digestibility trials <strong>and</strong> the<br />

results showed that:<br />

(i) The laboratory parameters of choice for the prediction of IVTDMD were: %CP,<br />

fibre (either in terms of % NDF or %CF) <strong>and</strong> % T.A. CF (%) was observed to be<br />

more promising than % NDF. The values of simplecorrelation coefficients were 0.90<br />

(S.E.=3.22) <strong>and</strong> 0.70 (S.E.=5.30) respectively.<br />

(ii) In comparison to the use of single laboratory estimate (CP or NDF or CF), the efficiency<br />

of the prediction of IVIDMD was not much improved in most of the cases <strong>and</strong><br />

where morethan one chemical constituent were employed <strong>and</strong> the best fits were as<br />

follows.<br />

(a)<br />

IVTDMD=-I.25 CF % +11466 (N=30;Y=0.90: SE=3.22)<br />

(b) IVTDMD=--=-1.21 CF ~~ +0.42 CF ~~ t 109.13 (n=30, r=0.92; SE=2.90)<br />

Twenty one observations on actuallv ingested herbage oat <strong>and</strong> three similar observation<br />

each on fodder matha (dough stage), cowpea (100;;:' flowering) <strong>and</strong> M. P. chari (Milk stage)<br />

were utilized in the computation of the above equations.<br />

Studies on guar silage.<br />

5, varietes of guar (viz., <strong>IGFRI</strong> S-212, HG 75, F.S. 277, HFG 119 <strong>and</strong> HG 182) grown<br />

during summer were ensiled either as such immediately or after wilting for 24 hrs in shade.<br />

After 60 da, s of ensiling, silos were opened for organoleptic tests <strong>and</strong> biochemical<br />

evaluation for quality traits. Organoleptic tests revealed that all the treatments gave ammonical<br />

odour. Due to more moisture, the texture of the sihg:s was not good in unwilted material as<br />

compired to willed herbage.<br />

Biochemical observations revealed that pH or all the silages was exceptionally high<br />

(6 ',7 to 8.:6). Wilted Sil.lgCS had higher pH (8.19 averagejthan unwilted ones (7.16).<br />

N;-{3-N: The production of a'lll11onical-N was very high in ali the treatments <strong>and</strong> this<br />

constituted 25.8 to 50.0~1a of total nitrogen. It was observed that wilting reduced NH3-N<br />

p:oduction.<br />

Acids <strong>and</strong> alcohol: There was very high production of volatile fatty acid (range 7.59<br />

--14.88~'t) <strong>and</strong> it was not significantly dfferent in varieties under test (range 10.36-12.03%):<br />

However, wilting reduced drastically its production from 14.2% to a net 8.53%. Alcohol<br />

P" !t ction varied between 0.88% <strong>and</strong> 2.65%. Wilting increased alcohol production from<br />

1.20% to 2 47~{<br />

In the absence of lactic acid <strong>and</strong> vary high production of butyric acid <strong>and</strong> acetic acid, the<br />

flieg index was zero; as such the quality was very bad. The main reason, which was thought to<br />

be responsible for p09r quality of Silage even at high dry matter (between 32.33%) was high<br />

concentration of water soluble N in the ingomg material.<br />

2. Quality of silage of hybrid napier (variety No.3) harvested at two stages of growth<br />

<strong>and</strong> grown under high f.rtiliry conditions.<br />

Hybrid napier (variety <strong>IGFRI</strong> No, 3)<br />

grown ncar cattle sned area containing 0.14 total<br />

nitrogen (soil rich in organic matter) was harvested at about 1:25 Ol<strong>and</strong> 2.50 m heights <strong>and</strong><br />

ensiled after chopping in laboratory glass silo immediately <strong>and</strong> also after over night willing.<br />

Wilting has reduced the buffering capacity <strong>and</strong> increased the water soluble carbohydrates<br />

at both heights. Crude protein was more at 1.25 m height than at 2,5 m height (12.47 &<br />

10.68% respectively) while NDF content had reverse trend (63.96~~ <strong>and</strong> 5.86% at two different<br />

stages).<br />

After about 60 days ( f storage, organolaptic tests revealed that all the four trcatments :<br />

183


gave good aroma <strong>and</strong> colour. Intensity of smell was less in wilted silages than unwilted ones,<br />

Perusal of the (table 31) indicated that all the silages were gcod in quality <strong>and</strong> wilting has not<br />

improved the quality of silage.<br />

3. Quality of hybrid napier (N. B. 21 variety) silages prepared at two stages of growth<br />

irrigated by sewage effluent.<br />

Hybrid napier (variety N. B.-21) grown in campus (Krishi Nagar colony) near a septic<br />

tank was harvested at 2 heights (1.5 <strong>and</strong> 3 m) <strong>and</strong> ensiled after chopping Immediately or after<br />

wilting over night in glass silos.<br />

Crude protein content was quite low. NDF content at both the heights remained more<br />

or less similar.<br />

After 60 days of ensiling organolaptic tests revealed that wilted material gave good<br />

aroma <strong>and</strong> texture compared to unwilted material. The data regarding biochemical parameters<br />

(table 33) indicated that unwilted silages were very poor (at both the heights) while wilted<br />

material gave "good" <strong>and</strong> 'very good' silage at 1.5 <strong>and</strong> 3 m heights respectively,<br />

This finding is contradictory to the observations of earlier experiment where hybrid<br />

napier No.3 had given good silage even at 16.8% dry matter. In the present case at 23% dry<br />

matter level it has given very poor silage.<br />

Data of these two experiments clearly suggests that when the protein content is high,<br />

wilting has no influence <strong>and</strong> is of nO advantage. But when the CP content is low wilting<br />

improves the quality of silage.<br />

4. Quality of silage prepared from the meterial grown under a system (System: Stylosanthes,<br />

Hybrid napier <strong>and</strong> Sesbania).<br />

Stylosanthes <strong>and</strong> hybrid napier were grown in alternate rows. After 3 rows of Stylo<br />

<strong>and</strong> 3 rows of Hybrid napier one row of Sesbania was planted. Approximate heights of these<br />

material when harvested for ensiling were as follows:<br />

These were ensiled after chopping separately in laboratory glass silos. In one treatment<br />

these were mixed in the proportion of their production as given bolow:<br />

Stylo 600, Napier-IOOO, Sesbania-200 (3:5:1). The dry matter of all the meterials<br />

varied between 31.5 to 33.0 per cent. Buffering capacity was similar in Stylosanthes <strong>and</strong><br />

hybrid napier. Crude protein content was very high in Sesbania (23.6 per cent) <strong>and</strong> least in<br />

hybrid napier (2.7 per cent). Water soluble N fraction of total N was very high in hybrid<br />

Napier (42.0 per cent of total nitrogen).<br />

After 6) days of storage, silages were opened <strong>and</strong> the organoleptic tests revealed that<br />

the silages made of stylo <strong>and</strong> hybrid napier were of moderate quality <strong>and</strong> that of Sesbania<br />

mixed herbrges Was of poor quality. Chemical analysis of rhese silages (table 32) revealed that<br />

all silages were of very poor quality. Production of NH 3-N <strong>and</strong> butyric acid was very high<br />

<strong>and</strong> lactic acid production was very low in J.Il the four silages. The Flieg indices of these<br />

silages were almost 'zero'.<br />

1.4 Influence of different additives/supplements in silage making.<br />

(A. B. Mojumdar)<br />

1. .Studies on the addition of Formaldehyde <strong>and</strong> Formic acid on fermentation pattern of<br />

Silage (In Vitro).<br />

Oat fodder cut at an early stage is leafy <strong>and</strong> is of high nutritive value (crude' protein<br />

in 16.58% <strong>and</strong> WSL 6.2 percent, AOF 44.36 percent, NOt


treated silage. Low ammonia levels 'in 1 per cent treatments produced good-quality silage.<br />

The sillage with no additive was badly preserved. Lower rate of application of formaldehyde<br />

did not appear to prevent the clostridial type of fermentation as seen by higher levels of butyric<br />

acid (2.60) <strong>and</strong> acetic acid (3.85). Thequality of this silage was poorer than the Control<br />

<strong>and</strong> the Flieg index was just 4. Higher rate of application of both the additives suppressed<br />

the acid fermentation gretly <strong>and</strong> there was no butyric acid formation <strong>and</strong> resulted in good<br />

The material was allowed to farrnen; for 90 days <strong>and</strong> then opened for sampling for<br />

organoleptic tests <strong>and</strong> biochemical analysis. Physical appearance of all the silages were good.<br />

Control silage had little offensive smell, low treated (upto 0.2 per cent addition) silage had<br />

little vinegar <strong>and</strong> rest had pleasant smell. All the silages were green in colour. The untreated<br />

silage had high pH (5.7) <strong>and</strong> treated silage had lower pH than sulphuric acid treated<br />

silage <strong>and</strong> this indicated little undesirable fermentation in former silage than the later.<br />

In all cases, the addition of formic acid <strong>and</strong> sulphuric acid resulted in lower values<br />

for ammonia than control (table 35).<br />

It was concluded that both organic as well as mineral acids were found to be equally<br />

good as preservatives in making good silage but former being slightly superior to later in<br />

suppressing tl.e fermentation. More equivalents of sulphuric acid is therefore would be required<br />

to check the fermentation effectively.<br />

4. Usefulness of formaldehyde <strong>and</strong> formic acid as silage additive for ensiling cereal crop<br />

like M. P. Chari.<br />

In this experiment, possibilities Were explored to make good silage of M. P. chari cut<br />

at an early stage of growth with out wilting by the use of two additives formic acid <strong>and</strong><br />

sulphuric acid.<br />

M. P. clari at 60 days of growth after sowing (pre-flowering stage) was cut, chaffed<br />

<strong>and</strong> ensiled directly with the following treatment (i) Untreated (ii) 0.25 % formaldehyde<br />

(iii) 0.25% formic acid (iv) 0.5% formaldehyde (v) 0.5% formic acid (vi) 10% formaldehyde<br />

(Vii) 10 %formic acid. All the additions were added on fresh weight basis.<br />

The silage were opened after 60 days of ensilment, All the silages were of yellowish<br />

green colour <strong>and</strong> good tex.ture with no mould formation.<br />

The results of biochemical analysis summerised in table revealed that all of them had<br />

ION pH (3.5-4.1). Protein breakdown was meager in all the silages including (he untreated<br />

(9.82) as indicated by the low ammonia value. This could be either due to low levels of<br />

nitrogen in original herbage or low prorolytic clostridial activity because of additives both<br />

formaldehyde as well as formic acid, the later being little more effective than the former.<br />

Lactic acid content was reduced by both additives.<br />

There was almost no butyric acid production with 0.5 % or higher rate of<br />

applications of both the additives.<br />

Thus all the acid treated silages were more stable than formaline treated silages. The<br />

quality of acid treated silages were also superior to other silages. 0.25 % added formic<br />

acid treated silage was of good quality while higher rate treated silages were excellent in<br />

quality as seen by Flieg index (88-96). The silage was of medium quality while 0.25%<br />

formlene treatment improved it to satisfactory quality. The higher rate of application of formaline<br />

produced good quality silage.<br />

It was concluded that good quality stable silage could be prepared from early harvested<br />

M. P. chari with lower rate of application of formic acid @ 0.25 to the fresh crop<br />

191


whereas the quantity of Iormaline required is more than of formic acid i. e. 0.5% to fresh<br />

crop for producing good quality silage.<br />

1.5 Micro nutrients in pastures <strong>and</strong> forage crops <strong>and</strong> their utilization.<br />

(K. S. Ramach<strong>and</strong>ra)<br />

1. A study was conducted with growing calves to find, out the effect of zinc supplementalion<br />

on the digestibility of proximate principles hematological paramet~rs<strong>and</strong> growth<br />

performance of Zebu calves.<br />

15 growing calves used for the study were divided into 3 groups 0[,5 calves each,<br />

according to their body weights. The animals in group 1 Were. offered a basal diet (35 ppm<br />

zinc) whereas, the animals in group 2 <strong>and</strong> 3 were given the basal diet, supplemmted with 65<br />

<strong>and</strong> 80 ppm of zinc as zinc sulphate. The study was conducted for. 90 d1J.Ys a.,np the last Seven<br />

days of which constituted the collection period.<br />

Zir;c supplementation increased the levels of hemoglobin content, packed cell volume<br />

<strong>and</strong> zine concentration in the blood. The results were however, not statistically significant. The<br />

results are presented in table 36.<br />

The supplementation of zinc did not have any significant effect on the digestibility of<br />

dry matter, ether extract, crude protein, crude fibre <strong>and</strong> nitrogea free extract.<br />

192 )


The effect of zinc supplementation on tissue protein deposition was also studied. It<br />

was observed that zinc influences the tissue protein deposition. The percentage of nitrogen<br />

consumed which was deposited as tissue protein was 6.21%, 9.29% <strong>and</strong> 8.9% for groups I, 2<br />

<strong>and</strong> 3, respectively. It was inferred that zinc plays a role in protein metabolism at the tissue<br />

level, However, the exact mechanism by which zinc influences the protein metabolism is yet<br />

to be studied.<br />

Satisfac: ory growth rates were obs rvcd in the animals of all the three groups. Zinc<br />

supplementation reduced the average dry matter intake but influenced the efficiency of feed<br />

conversion.<br />

From the above study it was conclud ~J that zinc has a vital role in the growth <strong>and</strong> feed<br />

utilization efficiency in growing calves <strong>and</strong> the optimum requirement of zinc for growing calves<br />

is around 90-)(0 p,)m. In an earlier study, it was observed that the zinc content ,of the natural<br />

grazing areas of Bundelkh<strong>and</strong> region is below the normal suggested levels <strong>and</strong> there is a need<br />

for the region with zinc. The present study has supported the earlier views.<br />

2. Micro element status of Leucaena leucocephala fodder tree leaves;<br />

Three types of Leucaena leucocephala viz. Salvador, Peruvian <strong>and</strong> Hawain were studied<br />

(the leaves Were collected from the fodder trees grown in the field of Dr. V. K. Gupta,<br />

Scientist S-:2 of ASP Division). The leaves were analysed for the levels of zinc, copper, iron,<br />

cobalt <strong>and</strong> manganese. The results are presented in table 36).<br />

have an adequate supply of theimportant trace minerals. It appeared that the fodder tree leaves<br />

are an excellent source of copper, cobalt, manganese <strong>and</strong> iron. The zinc content appeared to be<br />

PAR 2: NUTRITIONAL EVALUATION OF FORAGES AND FORAGE PRODUCT­<br />

ION SYSTEMS.<br />

2.1 Investigations on various chemical <strong>and</strong> physical attributes of forages on the<br />

intake as well as digestibility coefficients of various nutrients.<br />

(V. C. Pachauri)<br />

1. Nutritive value of Para grass.<br />

Two experiments were conducted to de-termine nutritive value of paragrass<br />

(Brachcria mutica) at two stages of growth i. e. green (45% OM) <strong>and</strong> partly dry (73% DM)<br />

on growing cow calves <strong>and</strong> buffalo calves (3+3). The ration was computed in such a manner<br />

that the protein requirement of the animals was met by concentrate mixture <strong>and</strong> paragrass in<br />

the ratio of 75:25.<br />

Three growing buffalo calves <strong>and</strong> cow calves were selected <strong>and</strong> distributed into two<br />

groups They were offered ad-lib green paragrass <strong>and</strong> required quantity of concentrate. Metabolism<br />

trial of seven day period was conducted after about 45 days of preliminary feeding. At<br />

the time af feeding trial paragrass had 45% dry m uter. Frorn the data of chemical composition<br />

it was seen that C. P. content of the grass (3.16%) was low <strong>and</strong> NDF content (58.04)<br />

was high.<br />

Intake <strong>and</strong> digestibility coefficients of nutrients have been given in table 38. Average<br />

intake of dry matter (DM). digestible crude protein (DCP) <strong>and</strong> total digestible nutrients<br />

(TON) in buffalo calves <strong>and</strong> cow calves was 340 kg, 3.98 kg; 0.16 kg, 0.24 kg <strong>and</strong> 1.49 kg,<br />

231 kg (per 100 kg live weight) respectively. Perusal of the data indicate that the digestibility<br />

coefficients of the nutrients were higher in cow calves than buffalo calves. The study showed<br />

that this forage was utilised more efficiently by cow calves than buffalo calves, especially, when<br />

the dry matter content of the paragrass was about 45~~. The nitrogen retention (g per head per<br />

day) was higher in cow calves (+29.12) than buffalo calves (+10.99). However, the daily<br />

weight gain recorded by buffalo calves was (kg per head per day) @ 0.40 kg while that of<br />

cow calves was @ 0.38 kg in 58 days.<br />

2. Nutritive value of paragrass (spring growth) in buffalo <strong>and</strong> cow calves.<br />

The animals of experiment 1 were continued in experiment 2 <strong>and</strong> were fed ad lib<br />

paragrass <strong>and</strong> 75% of the protein requirements of the individual calves were met through<br />

concentrate. The herbage at this stage of growth contained very high DM, the CP was 3.45%<br />

<strong>and</strong> NDF 79.92%. The experimental feeding lasted for about 90 days followed by seven<br />

day metabolism trial. The intake <strong>and</strong> digestibility coefficients of nutrients have been presented<br />

in table 39. Intake of DM, DCP <strong>and</strong> TDN in buffalo <strong>and</strong> cow calves was 2.90 kg, 3.16 kg,<br />

0.18 kg, 0.17 kg, 1.70 kg, 2.44 kg (per 100 kg L W) respectively.<br />

The perusal of the data showed that the digestibility Coefficients of the nutrients were<br />

higher in buffalo calves than cow calves, while in experiment I when grass was green the digestibility<br />

coefficients were higher in cow calves. Live weight gains (kg per head per day) in<br />

buffalo <strong>and</strong> cow calves were 0.39 g <strong>and</strong> 0.29 kg respectively. The nitrogen retention was<br />

higher in buffalo calves than cow calves (27.20 g <strong>and</strong> 24.09 g respectively). The ration in<br />

experiment I supplied in buffalo <strong>and</strong> cow calves 4'86%, 6.11 ~~ DCP <strong>and</strong> 45.30%, 59.79% TON<br />

whi'e in experiment 2 they were 6.27%, 5.28~~ DCP <strong>and</strong> 51.54~1o <strong>and</strong> 75.85% TDN respeclively<br />

Tne results of this experiment have conclusively shown that buffalo calves utilized nutrients<br />

better when the fodder became fibrous or lignified.<br />

2'3 Evaluation of protein quality of forages<br />

(P. Kumar)<br />

1. Evaluation of sweet sorghum fodder (Rio) based feeding system in cattle <strong>and</strong> buffaloes.<br />

In post monsoon months, when grazing does no, provide adequate nutrients, in some<br />

organised farms of Uttar Pradesh lactating animals are given sweet sorghum fodder (Rio-Sorghum<br />

bico lor) alongwith limited concentrate supplement. An experiment was undertaken<br />

at state Government Livestock Farm, Bharari, Jhansi on 18 Tharparkar cow') <strong>and</strong> 12<br />

murrah buffaloes of first lactation during the months of September-October to evaluate the<br />

fo Ilowing feeding practice.<br />

The animals were offered concentrate mixture in two instalments at the time of milking<br />

mixed with wheat bhoosa <strong>and</strong> moistened with water. The quantity of mixture was at the<br />

rate of 0,75 kg per cow <strong>and</strong> 1.25 kg per boffalo in the morning <strong>and</strong> same quantities in the<br />

evening. Chaffed Jowar fodder was offered ad libitum twice a day to ensure that the manger<br />

is never empty. Depending on the residue left in the manger, the quantity of roughage was<br />

regulated <strong>and</strong> the feed consumed was recorded, Water was offered twice a day, After a<br />

preliminary feeding period of 3 weeks, a digestibility trial was conducted choosing 4 cows<br />

<strong>and</strong> 4 buffaloes to determine nutrient intake <strong>and</strong> utilisation for milk production'<br />

The results summarised in table 40 have shown that there was no significance betWeen<br />

the species in dry matter consumption when it was expressed on the basis of metabolic body<br />

size (t=.=2.38 NS).<br />

The digestibility of dry matter, cellulose, ether extract was significantly higher in buffaloes.<br />

protein digestibility was not significantly different III cows <strong>and</strong> buffaloes. On the whole<br />

buffaloes have utilized nutrients better than cattle from Jowar fodder. This feeding regime<br />

did not significantly effect milk produced in both species <strong>and</strong> supported 3-4 litres of milk<br />

production/day.<br />

2, Nutrient status of pastures/grassl<strong>and</strong>s in Bundelxh<strong>and</strong>.<br />

In Bundelkh<strong>and</strong> region, the availability of green fodder from natural grassl<strong>and</strong>s to the<br />

grazing livestock is restricted to monsoon <strong>and</strong> early post monsoon months only, so also the<br />

availability of nutrients. It would be possible to obtain optimum satisfactory levels of production<br />

into minimum levels of supplementation during this part of the year. The farming<br />

communities which are predominantly poor can be helped to get better returns from their<br />

livestock with minimum expenditure on supplemental feeding if the nutrient status of grassl<strong>and</strong>s<br />

ale determined. Therefore this investigation of nutritional survey was undertaken<br />

during the months of October-November,<br />

Samples were collected from 6-8 locations (villages) in each district <strong>and</strong> in each lceation,<br />

samples were drawn from four different points <strong>and</strong> pooled to make it representative of<br />

that location, Botanical classification of two common/predominant species of each site were<br />

identified with the help of a Botanist <strong>and</strong> were recorded, Samples were first air dried <strong>and</strong><br />

subsequently dried in an oven to constant weight. Dried herbage samples were powdered<br />

with precaution to avoid contamination <strong>and</strong> were utilzed for analysis, The average composition<br />

of all samples of each district were given in the table 41 perusal of the data shows that the<br />

protein content varied from 5.33 ± 1.29 to 9.37± 1,59 : the lignin was between 6,68%± 1.30<br />

to 8,48%±2.06, The protein level was just adequate for maintenance. The structural carbohydrates<br />

(NDF, Cellulose <strong>and</strong> lignin) did not differ significantly from district to<br />

district,<br />

The levels of copper zinc were much lower than the normal <strong>and</strong> therefore supplernentation<br />

of these two elernen ts is considered essential for grazing animals of this region. With<br />

regard to iron its availability is more or less satisfactory as compared to its requirement.<br />

2.4 Evaluation 'of pastures 'for growth 'in calves.<br />

(N. C. Verma <strong>and</strong> V. S. Upadhyaya)<br />

1. Evaluation of mature dry grass supplemented with Leucaena leucocephala <strong>and</strong> concentrate<br />

mixtur~ for growing cross-bred calves.<br />

Twelve cross-bred calves (3/4 Hariana-l- 1/4 Holstein) between 1-2 years of age weighing<br />

on an average 121 kg (90-171 kg) live weight were div.ded into three equal groups'<br />

Group I was maintained ad-lib feeding of mature chaffed dry gr:lss tSehlma neriosuni­<br />

Heteropogon contortus dominant) .Group II was maintained on ad lib feeding of dry grass<br />

plus 4 kg Leucaena leucoccphala foliage (leaves with soft twigs) per animal per day <strong>and</strong> Group<br />

III was maintained on ad lib feeding of dry grass plus 2 kg concentrates per animal per day.<br />

The experiment was conducted for 105 days. The digestibility trial <strong>and</strong> haemoglobin estimations<br />

were carried out at the end of the experimental feeding period. The dry ijrass was of<br />

very poor quality having only 3.1~~ CP <strong>and</strong> 28.7& C. fibre. Leucaena leaves supplied 16.5% CP<br />

<strong>and</strong> 22.8% C. fibre. The concentrate mixture was supplying 21.8% CP <strong>and</strong> 8.5% C. fibre.<br />

The proximate chemical composition, digestibility coefficients of different nutrients <strong>and</strong><br />

nutrient intake by calves have been presented in table 42 respectively.<br />

The dry matter digestibility of dry grass was low. The addition of Leucaene (about<br />

37.5% of total DMI) slightly improved the dry matter digesti bility, whereas addition of<br />

concentrate (about 32% of total OMI) increased the overall dry":matter digestibility (42.4% to<br />

47.8%) The addition of Leucacna <strong>and</strong> concentrate both reduced the crude fibre digestibility.<br />

No significant difference was recorded in the digestibility of ether extract <strong>and</strong> nitrogen free<br />

extract (NFE).'<br />

Dry matter intake was not increased due to Leucaena supplementation (Table 43)<br />

whereas it was increased due to concentrate supplementation.<br />

The OCP intake increased substantially due to Leucaena supplementation in group II<br />

but little difference was observed in supply of TON. The concentrate supplementation increased<br />

the availability of both DCP <strong>and</strong> TON in group III.<br />

III.<br />

The increased intake of protein <strong>and</strong> energy increased the haemoglobin level in group<br />

1<br />

The animals of group I lost on an average 240± 39 g live weight/day while the animals<br />

of group If miinained their live weight <strong>and</strong> the animals of group III gained on an average<br />

285 g/animal/day. The loss of live weight in group I can be attributed to dificiency of DCP<br />

availability as per NRC (I971). Supplemental feeding of leucaena which is a rich source of<br />

protein <strong>and</strong> B carotene checked the loss in live weight in group II. Better growth performance<br />

in group III could be attributed to increased intake of DCP <strong>and</strong> TDN as compared to group<br />

I <strong>and</strong> II.<br />

2. Evaluation of Cenchrus ciliaris grass with <strong>and</strong> without Stylosanthes hamata for growing<br />

~ross bred calves.<br />

Eight cross bred calves (102-122 kg live weight) were divided into two groups of four<br />

animals each <strong>and</strong> allowed to graze 0) Cenchrus ciliaris (<strong>IGFRI</strong>-3108 <strong>and</strong> (ii) C. ciliaris grass<br />

+ Stylosanthes hamata (val'. Varano) during the month of August <strong>1984</strong>. It was recorded that<br />

the dry matter consumption was found to be 2.0 kg body weight in C. ciliaris grass <strong>and</strong> 1.87<br />

kg/lOa kg body weight in C. cilicris-vStylosanthes hamata group. The herbage utilization by<br />

the animals was 60.0% from C. ciliaris <strong>and</strong> 44.2% from mixed pasture of C. ciliaris +<br />

S. hamata.<br />

"<br />

After about a month the animals were stall fed during the months of September <strong>and</strong><br />

October, <strong>1984</strong>; group I was offered C. ciliaris grass <strong>and</strong> group II was offeredC. ciliaris grass<br />

-s-Stylosanthes hamata (in the ratio of 1:1 fresh basis) which were harvested from the same<br />

plot. The body weights of the animals were recorded at fortnightly intervals. At the end of<br />

the feeding experiment digestibility trial was conducted to determine the DM intake, <strong>and</strong> the<br />

digestibility coefficients of different nutrients to assess the nutritional status of these harbages.<br />

The haematological constituents were determined at the start <strong>and</strong> end of the experimental<br />

feedi~g period.<br />

The Cenchrus grass supplied 5.2% CP, 42.43% CF <strong>and</strong> 10.73% Ash <strong>and</strong> Cenchrus­<br />

Stylo mixture furnished 8.82% CP, 39.94% CF <strong>and</strong> 9.34~~ Ash. Digestibility coefficients of<br />

nutrients of feeds have been presented in table the data about nutrient intake, live weight gain,<br />

haemoglobin <strong>and</strong> packed cell volume of blood of experimental animals has been presented in<br />

table.<br />

On the perusal of data in tables 45 <strong>and</strong> 46 it was observed that there was no difference<br />

in dry matter intake <strong>and</strong> digestibility in group I <strong>and</strong> II. However the crude protein <strong>and</strong> NFE<br />

contents <strong>and</strong> their digestibility were found higher, in mixed herbage as compared to C. ciliaris<br />

grass alone. Crude fibre <strong>and</strong> ether extract intake <strong>and</strong> their digestibility csefficients were found<br />

higher in group (C. ciliaris grass) as compared to group II from the mixed herbage of<br />

( 204 )


C. ciliaris <strong>and</strong> S. hamata. Availability more digestible crude protein (group II) resulted in<br />

their better performance than group-l (pure C. ciliaris grass}.<br />

The average growth retes recorded in group I <strong>and</strong> II were 210 g <strong>and</strong> 2.75.5 g/head/day<br />

respectively. The haemoglobin <strong>and</strong> packed cell volume of blood was found- to be 10:25% <strong>and</strong><br />

43.3 per cent in group I <strong>and</strong> 1O.62~~ <strong>and</strong> 13.4 per cent in group II. '<br />

The results have shown that the performance of growing calves was better when fed<br />

mixed herbage of C. ciliaris grass <strong>and</strong> Stylosanthes hamata (1:1 ratio as compared to C.<br />

ciliaris grass alone).<br />

3. Evaluation of Sehima neroosum dominated natural grassl<strong>and</strong> for growing cross bred calves.<br />

Eight cross-bred calves (94-155 kg live weight) were allowed for grazing in Sehima<br />

neroosum dominated natural grassl<strong>and</strong> from 1.9.84 to 15.12.84. The utilization of herbage<br />

from the above mentioned grassl<strong>and</strong> was found to be 1.16 per cent. The average dry matter<br />

consumption by the animals was found to be 2.52 k~/IOO,kg live weight. The average live<br />

weight gain was found to be 280 g/head/day in cross bred calves grazing S. neroosum<br />

dominated natural grassl<strong>and</strong> without any supplementation.<br />

4, Evaluation of two varieties of hybrid napier grass (variety <strong>IGFRI</strong>-3 <strong>and</strong> NB-21) for<br />

growing cross-bread calves,<br />

Eight cross-bred calves (l04-144 kg body weight) were divided into two groups of<br />

four animals each. Group I was offered hybrid napier grass var. NB-21 (harvested at flowering<br />

stage in the months of October, November 84) <strong>and</strong> group 4 was offered hybrid napier.<br />

IGFRl-3 ad-lib at the same stage of growth. A digestibility trial was conducted for 5 days<br />

after a preliminary feeding period of IS days.<br />

The dry matter intake <strong>and</strong> digestibility was found to be higher (2.24 kg/lOO B. W,<br />

<strong>and</strong> 51.4% respectively in group II fed with hybrid napier No. 3 as compared to the its<br />

group fed with hybrid napier NB-21 (D M. 1. 1.22 kg/100 B. W. D. M. Dig.<br />

26.7%). The animals of group I lost their body weight whereas the animals of<br />

group II maintained their live weight. The further analysis is in progress to determine the<br />

proximate composition <strong>and</strong> nutritive value of the two varieties of hybrid napier grass.<br />

The results indicated that h)brid napier grass (variety NB-21 <strong>and</strong> <strong>IGFRI</strong>-3) need<br />

supplernentat ion.<br />

2.5 Evaluation of forages fOI milk production in catt:e,<br />

(V. S. Upadhyay)<br />

1. Evaluation of Bermuda grass pasture for milk production.<br />

~ 205 )


An experiment was conducted to evaluate unfertilized Bermuda grass pasture for milk<br />

production under grazing condition. Three milch cows of l st lacraticn having on an average<br />

250 kg live weight <strong>and</strong> had completed 77 (65-95) days of lactation were used as experimental<br />

animals. All the animals were given concentrate @ 1 kg/animal/day for let down of milk in<br />

addition to grazing of Bermuda grass paddock for 8 hours daily.<br />

The animals produced or. an average 4.0-5.0 kg milk daily containing on an average 5.6<br />

per cent fat, 14.14 per Ce1'1t total solids <strong>and</strong> 8.51 per cent solid-not-fat with satisfactory live<br />

weight gain.<br />

The animals of above mentioned experiment were further continued on same pasture<br />

but I kg concentrate was replaced by 10 kg Leucaena foliage. Two weeks adjustment period<br />

was followed by two weeks experimental period. The results of the experiment showed that<br />

animals producing upto 4 kg milk per day could be maintained on unferulized Bermuda grass<br />

pasture plus 10 kg Leucaena foliage during the month of September.<br />

2. Evaluation of Iseilema laxum grass at mature stage for milk production.<br />

An experiment was conducted to evaluate the natural Iseilema laxum grass at mature<br />

stage for milk production under stall fed condition. Three first calvers in their mid stage of<br />

lactation were used as experimental animals. The experiment lasted for two week adjustment<br />

followed by three weeks test period. The animals were given I kg concentrate per animaljday<br />

for let down of milk in addition to ad lib feeding of unchaffed grass.<br />

average 3 kg milk per day without any gain or loss in live<br />

The animals of above mentioned experiment were further continued on Lseilema feeding<br />

during the month of November ~ut an additional 5 kg Leucaena foliage per animal/day was<br />

given to compensate the loss of nutrients due to the "averaging stage of maturity of the grass.<br />

One week adjustment followed by two week .est period was allowed in this experiment.<br />

weight.<br />

Animals produced on an average 2.7 kg milk per day without gain or loss in live<br />

Thus, the above findings indicate that animals producing upto 5 kg milk in The<br />

beginning ofJuly could be maintained on Bermuda grass pasture with supplementation of 1 kg<br />

concentrate of 5-10 kg Leucaena upto September. Mature naiur..l Iseilema grass could sustain<br />

upto 3 kg milk per day upto November with supplementation of 1 kg concentrate <strong>and</strong> 5 kg<br />

Leucaena foliage per animal per day.<br />

3. Evaluation of mixed forage silage <strong>and</strong> green hybri,d napier for milk production.<br />

A mixed forage silage prepared from unchafl'ed hybrid napier para grass "plus (proportion<br />

non-specified) obtained.. from post-harvest technology unit (T 1<br />

) <strong>and</strong> green hybrid<br />

napier obtained from system synthesis of karari block (T 2 ) were evaluted for milk production<br />

using eight lactating cows, The animals were divided into two groups consisting of four animals<br />

in each group based on their .lactation number <strong>and</strong> milkyield etc, ·Animals of treatment lst<br />

group were given 3 kg dry grass, 1 kg concenrrate+ad 'lib silage ~hile animals of treatment<br />

lInd group received 3 kg dry grass+l kg concentrate-l-ee" lib green hybrid napier (unchaffed).<br />

Results indicate that animals of silage group produced on an average 3.4 kg milk/animal<br />

/day while animals of hybrid napier group produced 4.8 kg milkjarumaljday. However,<br />

animals of both the groups lost their live weights. Animals of hybrid napier group consumed<br />

about 1 kg dry grass per day.<br />

4. Evaluation of dry glass plus concentrate for milk production.<br />

An experiment was conducted to evaluate the feeding value of mature dry grass ad lib<br />

pk,s concentrate during summer Season. The concentrate was given @ 1 kg for maintenance<br />

plus 1 kg for every two kg milk produced. Four milch cows giving 3-6 kg milk/day <strong>and</strong> of<br />

which were of lower age group <strong>and</strong> not fully developed ruminants. No apparent ill effects of<br />

Leucuena feeding as sole diet were recorded. Thus, results confirm the previous years finding<br />

that growing kids can gain live weight satisfactorily without any adverse effect, even as a<br />

(A. Rekib)<br />

1. Chemical composition <strong>and</strong> in vitro dry matter digestibility of Sesbania aegyptica as<br />

affected by seasonal changes.<br />

Leaf samples of S. aegyptica were collected round the year at hi-monthly intervals, to<br />

study the effect of seasons on the chemical composition <strong>and</strong> in vitro dry matter digestibility<br />

values. They were dried <strong>and</strong> grounded co pass 40 mesh seive, The' leaf meal was then alialysed<br />

by following the stan dared methods. The detailed results are given in table 47,<br />

( 211 )


Table 47<br />

Chemical composition <strong>and</strong> IVTDMD as influenced by seasonal changes.<br />

(


From the chemical composition detailed in the above table it is indicated that this<br />

fodder could be harvested for maximum nutrient content either in January or in July. But<br />

being a tropical shrub it would be advisable to harvest S. aegypt ica in the month of July.<br />

2. Chemical composition <strong>and</strong> in vitro dry matter digestibility of some tropical pasture<br />

legume in comparison with S. aegyptica.<br />

Sesbania aegyptica, 7 entries of siratro; Stylosanthes hamata, S. gracilis S. oiscosa,<br />

S. scabra (40205) <strong>and</strong> S. scabra (40289) were harvested <strong>and</strong> dried in < hot air oven. These<br />

were then grounded to pass 60 mesh sieve. D~tail~d chemical composition. in vitro true dry<br />

matter digestibility <strong>and</strong> % digestibility of N OF was determined <strong>and</strong> presented in<br />

table 48.<br />

Perusal of the data in table 48 shows that S. aegypt ica has higher level of protein <strong>and</strong><br />

lower levels of lignin, cellulose <strong>and</strong> other structural corbohyr'rates, The IVTOMD value<br />

also was higher in Sesbania than the other forages.<br />

3. Chemical composition <strong>and</strong> in vitro dry matter digestibility of fodder tree leaves.<br />

Leucacna Ieucocephcla <strong>and</strong> Sesbania aegyptica are considered to be important fodder<br />

trees/shrubs grown in the humid tropics. These two species could be fed to the livestok primarily<br />

as a protein supplement. It was, therefore. considered to compare their nutritive value<br />

when grown <strong>and</strong> harvested under identical conditions.<br />

Both L. leucocephala <strong>and</strong> S. oegyptica grown in the same plot <strong>and</strong> their leaves were<br />

harvested in March, 84, dried at 800C <strong>and</strong> grounded to pass 60 mesh shieve. Detailed chemical<br />

composition <strong>and</strong> in vitro true dry matter digestibility were determined.<br />

Average chemical composition, in vitro true dry matter digestibility <strong>and</strong> % digestibility<br />

of cell wall fraction are presented in the table 49. The results indicated that S. aegyptica<br />

was superior to L. leucocephala.<br />

4. Comparision of the nutritive value of S. aegyptica with cultivated legume fodders.<br />

Sesbania aegyptica was found to contain higher percentage of essential nutrients, but in<br />

some experiments, conducted earlier with growing goats, it gave lower body weight gain than<br />

berscem fodder.<br />

In order to see if there is any basic difference in these chemical constituents, this<br />

experiment was uidertaken.<br />

Leaf samples of S. aegyptica COII'P~:J <strong>and</strong> berseem fodder were collected, dried at 800C<br />

<strong>and</strong> processed further for detailed chemical analysis <strong>and</strong> determined their in vitro true dry<br />

matter digestibility.<br />

Crude protein varied from 14.59-22.80 with an average value of 18.49%. Maximum<br />

CP% was recorded in S. aegyptica <strong>and</strong> cowpea fodder had lowest content of crude protein<br />

(14.59%). Thus S. aegyptiaca was considered better than other two legume fodders.<br />

Cell well (NDF) <strong>and</strong> cell contents ratios are considered to be of much nutritional<br />

significance. Greater quality of cell contents is always associated with greater utilization. In the<br />

present experiment both S. aegyptica <strong>and</strong> berseern fodder were found to contain 31.21 <strong>and</strong><br />

32.33% NOF <strong>and</strong> 68.79 <strong>and</strong> 67.66~~ cell contents respectively while cowpea contained higher<br />

NOF content.<br />

Fraction of cell wall (Lionocellulose (AOF), lignin cellulose <strong>and</strong> Merni cellulose)<br />

content was further fractionated to know greater details about these legume forages:<br />

In the present study. S. aegyptiaca found to contain lowest ADF (19.78) <strong>and</strong> higher<br />

lignin (7.61) levels as compared to two other fodders, Cellulose content (AOF-lignin) was<br />

found to be very low, On the contrary, cowpea contained highest AOF (39.32) <strong>and</strong> cellulose<br />

(32.18). Berseern fodder contained lowest amount of lignin <strong>and</strong> Hemicellulose (4.37 & 5.32)<br />

<strong>and</strong> was therefore considered superior to the other two fodders.<br />

Ash <strong>and</strong> silica: Little variation in the ash <strong>and</strong> silica content of these three fodders was<br />

recorded. The average value of ash <strong>and</strong> silica was found to be 13.52 <strong>and</strong> 0.75% respectively.<br />

It has also been observed that the acid soluble mineral content was quite high (12.77%).<br />

In vitro true dry matter digestibility (IVTOMO) : It was sound that there was not<br />

much difference in the IVTOMO value of these three legume forage. Average value was 83.12<br />

<strong>and</strong> cowpea· contained slightly lower IVTOMO'value (80.03). These observations show that<br />

all the three legume forages are highly digestible (in vitro).<br />

NOF digestibility: In the present experiment NOF digestibility of cowpea was found<br />

to be higher (61.75) than S. aegyptiaca <strong>and</strong> berseem fodders.<br />

From the above table, oat straw was considered to be superior to other straws/grass.<br />

It.is rich in CP, cell content <strong>and</strong> in vitro digestibility of dry matter as well as NDF.<br />

Wheat bhusa, paddy straw <strong>and</strong> sorghum kadbi could be grouped togather though<br />

sorghum contained greater quantity of crude protein while paddy straw was found to have<br />

high of silica, an antinutrition factor.<br />

Mixed dry grass though contains. highest amount of crude protein also contains other<br />

antifactors in greater quantity as well. IVl DMD <strong>and</strong> % digestibility of NDF is lower than<br />

other crop residues.<br />

6. Comparison of nutritive value of berscern fodder <strong>and</strong> its bhusa.<br />

In order to know the nutritive value of bersezm bhusa in detail, chemical composition<br />

<strong>and</strong> in viiro true dry matter digestibility value was determined <strong>and</strong> compared with that of the<br />

berseem fodder harvested from the same field in January <strong>1984</strong>:<br />

Crude protein content of berseern bhusa was found to be 8.68 <strong>and</strong> that the fodder was<br />

18.09%. This was considered to be well within the critical level of CP% as was reported<br />

earlier from this laboratory.<br />

In the present experiment, chemical composition in vitro true digestibility of dry matter<br />

<strong>and</strong> that of cell wall fraction of berseern bhusa <strong>and</strong> five other cereal straws was determined <strong>and</strong><br />

Results shows that berseem bhusa contains 8. 7~% crude protein which is considered<br />

sufficient for providing the maintenance r-quirernen t of a ruminant. It was also found to<br />

contain lower amount of NDF, hemicellulose <strong>and</strong> silica with high cell contents than that of<br />

cereal straws. But it contained higher amount of ADF <strong>and</strong> lignin. This however, was quite,<br />

expected since legume forages are known to contain higher amounts of lignin <strong>and</strong> ADF. It was<br />

found that the IVTDMD <strong>and</strong> % digestibility of NDF of berseern fodder was lower than that<br />

of cereal fodders. This might be due to high lignin content of berseern bhusa which might have<br />

inhibited in vitro digestibility of both dry matter <strong>and</strong> cell wall fractions.<br />

8 Nutritive evaluation of Stylo species as influenced hy phosphatic fer tillzer<br />

(A. Rekib <strong>and</strong> K. C. Kanodia)<br />

Nutritional evaluation of 6 species of Stylo was done in collaboration of OM Division<br />

when they were grown with three phosphate levels <strong>and</strong> harvested in February <strong>and</strong> September,<br />

<strong>1984</strong>. From the available data it may be stated that phosphatic fertilization did not influence<br />

significantly the chemical composition <strong>and</strong> nutritive value of Stylo species but the differences<br />

between specie'> <strong>and</strong> month of harvest were apparent,<br />

1. Investigation on Rhyniosia minima.<br />

( 217


Rhyncosia minima is a widely occur.ng forage legume in natural grassl<strong>and</strong> area. Detailed<br />

chemical investigations were undertaken to characterise its chemical constituents to assess<br />

their effect on utilization of this forage by livestock. Rhyncosia minima was found to contain<br />

15.9% of CP hentricecontane myricyl sp alcohol, B-sito, sterol, B-si to sterol-D glucoside,<br />

Isovitexin, Vitexin, Vicenin-Z <strong>and</strong> pinitol, In continuation to these studies, further investigations<br />

were undertaken on the amino acid make-up of leaf-protein. The powdered leaves<br />

of Rnyncosia minima were defatted <strong>and</strong> extracted with 70% ethanol in soxhlet extractor. The<br />

solvent was removed under pressure <strong>and</strong> extractive was disolved in minimum quantity of butanol.<br />

It was examined on paper chromatography using Butnol. Acetic acid-water (4:1.5) <strong>and</strong><br />

phenol saturated with ammonia. Ninhydrin in acetone was used as detect ing agent. The<br />

amino acids were identified by comparison of their Rf value with those of reference amino<br />

acids, The identified amino acids were glutamic acid, aspartic acid, glycine, alanine, Valine,<br />

Threonine serine, histadine, Isoleucine, phenyl alanine, proline <strong>and</strong> arginine.<br />

The bound amino acids were also examined, on paper chromatography, after hydrolysing<br />

leaves powder with 6 NHCl; 80~~ Fomic acid (1:1) in sealed tubes at 100~ till it gave<br />

the -ve biuret test. The hydrolysate after usual work up, showed the presence of Valine,<br />

arginine. glutamine, metheonine, alanine, Isoleucine, leucine, lysine, aspartic acid, trytophan.<br />

preline <strong>and</strong> cystine.<br />

Rhyncosia minima was found to possess most of the essential<br />

acids required for nutrition. The compounds of flovinoid group<br />

have been reported to cause reproductive disturbances.<br />

<strong>and</strong> non-essential amino<br />

were also present, which<br />

C. P., 2'08% Ca <strong>and</strong> 0.18% P. The plant did not contain oxalates, nitrates or nitro compounds,<br />

of indospicine (a hepatotoxin present in I spicatav The foliage did not give positive<br />

tests for cyanogenic glycosides <strong>and</strong> saponin. Extraction of powdered dry leaves (6 kg) with<br />

rectified spirit <strong>and</strong> fraction with petroleum ether, benzene, ethyl acetate <strong>and</strong> exhaustive chromotography<br />

on silica gel columns yielded hentriacontanol, triacontanol fatty esters. ethylcaffeate,<br />

organic constituents were isolated <strong>and</strong> identified using physico-chemical instrumentation<br />

techniques. However, none of these constituents are likely to possess any physiological<br />

action at the existing level. This leguminous forage possesses good potential for utilization<br />

as livestock feed.<br />

from 303-3330K, 30-80% <strong>and</strong> 293-308 0K, 30-80%. The desorption isotherms for grass <strong>and</strong><br />

The values of constants C <strong>and</strong> n, obtained through the least square method, showed<br />

temperature dependence for both the crops. The value of C increased with the increace in<br />

temperature, whereas the value of n followed a reverse trend. The following exponential<br />

equations of the form :<br />

putting the respective values of C <strong>and</strong> n in equation 1, generalised expressions for the<br />

observed <strong>and</strong> predicted values for grass <strong>and</strong> berseem were 0.996 <strong>and</strong> 0.994, respective] y. T'he<br />

Chi squar test showed highly non-significant variation at 0.99 probability level.<br />

The higher EMC values of grass upto 60%rh <strong>and</strong> of berseern beyond that indicated that<br />

desorption isotherm was influenced by the inherent plant characteristics.<br />

Vapour pressure of forage moisture:<br />

The values of vapour pressure of grass <strong>and</strong> berseem moisture were calculated for ihe<br />

range of temperature <strong>and</strong> moisture content from 30-60 0C, 10-40/~ (d.b.) for grass <strong>and</strong><br />

20-350C, 15-40~{, for berseern. The vapour pressure of both the product increased with the<br />

temperature <strong>and</strong> moisture content.<br />

Latent heat of vaporisation of forage moisture.<br />

The plots of vapour pressure of grass <strong>and</strong> berseem moisture against the saturation<br />

pressure of water vapour (taken from steam table at the same temperature) at each level of<br />

moisture content yielded straight lines. These plots are called othrner plots, <strong>and</strong> thus are<br />

expressable by the equation of the from.<br />

<strong>and</strong>, C==intercept of the straight line on Yaxis.<br />

In all cases, the latent heat ratio (LjV) was found greater than unity showing that the<br />

heat of products moisture is higher than that of water. The value of LjLl decreased with the<br />

increased forage moisture. The latent heat ratio at a given moisture content was higher for<br />

grass than that of berseem. The plot of LjLt Vs. M. C. showed linear relationship on semi-log<br />

scale thus showing a relationship of the form of :<br />

The LjLl of grass is higher than that of berseern at all the moisture contents, but the<br />

difference between the two decreased with the increase of M.C. The above relationships between<br />

LjU <strong>and</strong> EMC showed an excellent correlation (r=0.994 ana 0.986 <strong>and</strong> Chi square 0.99)<br />

Effect of air flow <strong>and</strong> packing density of hay on staiic pressure.<br />

The resistance of grass <strong>and</strong> berseem hay to air flow rates of 0.03-0Am3jsec-m2 <strong>and</strong><br />

packing densities of 26.4-100 kgm-- a have been determined. The results indicated that the<br />

static pressure-air flow relationship tend to fit the model.<br />

1.2 To deter mine the material <strong>and</strong> processing characteristics of grass <strong>and</strong> grass silage.<br />

(Jai Singh)<br />

( 221


Density of stored material <strong>and</strong> degree of filling are the main factors determining the<br />

proportionate. cost load on the silage. The chop length, height of filling <strong>and</strong> DM content affect<br />

.the silage density. The following relationship have been developed for pit silo.<br />

Where<br />

D=densiry of silage, kgjm3 ; h=height of filling, M=dry matter content, %<br />

The results presented revealed that higher density, both on the fresh <strong>and</strong> dry weight<br />

basis can be obtained in pit silos. It was also observed that as the chop length decreased<br />

chopper capacity reduced significantly but the density did not increase to that extent.<br />

The main task of the laboratory investigation was to establis.i the optimum specific:<br />

<strong>and</strong> other parameters required for designing a wafering machine.<br />

Wheat Bhusa : Wafers were prepared at four moisture contents, 10.12,12.22,15.22,<br />

22.22 <strong>and</strong> 46.67 per cent. w. b. The results indicated that in the given range of MC the<br />

expansion increased with the M. C. The h<strong>and</strong>leability test indicated that the wafers prepared<br />

at 10.12, 22.22 <strong>and</strong> 46.67% MC disintegrated on slight h<strong>and</strong>ling <strong>and</strong> the water formed at<br />

15.22~~ MC disintegrated at 3rd fall. Heating of bhusa before wafering also did not improve<br />

the water stability. Addition of molasses at the rate of 5% <strong>and</strong> 22.22% MC gave the least<br />

reduction in density (28.57%).<br />

Grass: None of the wafers prepared at<br />

disintegrated on h<strong>and</strong>ling.<br />

1. Investigation of a set of improved implements on farmers fields,<br />

The set of improved implements (tillage <strong>and</strong> seeding) consisted of sabsh plough, bukhar,<br />

animal- drawn disc harrow, Igfri country plough mounted seed drill <strong>and</strong> a 3 row seed-cumfertilizer<br />

drill. The set was used in Rabi, 84 for wheat crop. It was tried in comparison to<br />

the local bukhar pat ela <strong>and</strong> sowing behind the plough. The total cost on tillage <strong>and</strong> seeding<br />

operations were Rs, 926.80, 636 80 <strong>and</strong> :02.90 per hectare in local, improved with Igfri drill<br />

<strong>and</strong> improved with 3 row drill, respectively.<br />

2. Field evaluation of animal drawn seed-cum-fertilizer drills]<br />

Igfri country plough seeding attachment: Use of the drill resulted in 9-11% higher<br />

mean values of total yield (grain -l-straw) in wheat over the traditional method of sowing.<br />

The differences, however were not statistically significant. Similar results were obtained on<br />

seed germination <strong>and</strong> establishment in Rabi, <strong>1984</strong>.<br />

4, Studies on the positional placement of seed <strong>and</strong> fertilizer.<br />

Test were conducted to investigate the effect of showing the mixture of seed <strong>and</strong> fertiiizer<br />

on germination, plant establishment <strong>and</strong> yield in both the, black <strong>and</strong> s<strong>and</strong>y loam soils<br />

under irrigated conditions. The basal doses for T 1 , T 2 <strong>and</strong> T 3 were urea 100 kg+ DAP 20 kg<br />

-l-Potash 100 kg+S.S.P. 400 kg. Urea 60 kg+DAP 20 kg-l-Potash 100 Kg+SSP 240 kg <strong>and</strong><br />

Urea 20 kg+ DAP, 20 kg+Potash 10 kg+SSP 120 kg per hectare.<br />

In addition, similar trials were conducted 00 farmers fields in wheat crop in black <strong>and</strong><br />

s<strong>and</strong>y loam soil. The farmers used a basal dose DAP varying from 50 kg per hectare.<br />

The no. of seeds germinated <strong>and</strong> established <strong>and</strong> the crop yields increased with the<br />

increase in fertilizer dose on the farmers fields The trials under controlled conditions<br />

also showed similar results regarding plant population. The data generated on farmer's fields<br />

exhibited that the seed <strong>and</strong> fertilizer can be mixed together for sowing. These findings would<br />

enable reducing the cost of seed drills.<br />

4. Development of seed drill furrow epeners for Bundelkh<strong>and</strong> soils.<br />

Two 'ypes of furrow openers (shovel <strong>and</strong> shoe type) were evaluated in comparison to<br />

Nari (Country plough bottom used for sowing purpose) both in irrigated <strong>and</strong> rain fed areas;<br />

Significant difference in plant st<strong>and</strong>. establishment <strong>and</strong> yield was noted under rainfed condition<br />

The difference under irrigated condition was not significant. Use of the extended shoe type<br />

furrow opener (similar to the desi plough bottom) resulted in 1.5-2.5 per cent higher yield<br />

gain fed black soils.<br />

DIVISION OF RURAL ECONOMICS AND BIOMETRICS<br />

REB-I ANALYSIS OF FARM MANAGEMENT AND ECONOMICS OF FORAGE<br />

PRODUCTION AND UTILIZATION SYSTEM.<br />

1.1 Economics of forage production <strong>and</strong> forage based animal production systems-studies<br />

based on data from experiments <strong>and</strong> demonstration trials laid out at C. R, Farm.<br />

(I. P. S, Yadav)<br />

. Economics of the establishment of mixed pastures of Cenchrus species <strong>and</strong> Dolichos lablab.<br />

The field experiments were conduted at <strong>IGFRI</strong>. Jhansi during 1983 on loamy red<br />

. rakar soil which was poor in fertility. The grasses, Cenchrus ciliaris <strong>and</strong> C. setigerlls were<br />

planted at 50 em row spacing <strong>and</strong> planting of one row of Dolichos lablab after everyone, two<br />

or three rows of Cenchrus ciliaris <strong>and</strong> C. setigerus grass was done.<br />

Total dry matter production (grass <strong>and</strong> legume mixtures) was maximised in the field of<br />

C. ciliaris-s-D, lablab planted in 1:1 ratio. During the study period, pure C. ciliaris producced<br />

maximum dry matter.<br />

The dry matter yield of grasses was reduced due to mixed cropping with D. lablab in<br />

the first year. The reduction in yield was due to low plant population of grasses as the seed<br />

rate was reduced proportionately; However, in the second year, the lesume population was<br />

very less <strong>and</strong> grasses covered the whole space. The dry matter yield of legume varied from<br />

11 .99 to 1.84 q/ha during the first year <strong>and</strong> 1.80 to 2.84 q/ha in the second year. The low<br />

yield of legume in second year was due to very less population of legume left in the field.<br />

Thus, it can be concluded that mixed pastures of Cenchrus species <strong>and</strong> D. lablab in 1:1<br />

ratio may be established for increasing the population of high quality forage from pastures;<br />

Further, it is suggested that under arid <strong>and</strong> semi-arid condition. D. lablab should be planted<br />

every year in the established pastures to mainain requisite population of the legume. cropping<br />

of D. lablab had no adverse effect on the forage production of grasses. There was improvement<br />

in the protein content in the mixed forage.<br />

.12 Marketing of milk products in Babina block of Jhansl district.<br />

(Mallayya)<br />

Marketing of milk <strong>and</strong> milk products in Babina block of Jhansi has been carried out.<br />

The marketing of Ghee, Curd <strong>and</strong> Khowa have been worked out separately, the study<br />

carried on total farmers on an average of the selected villages of Babina block revealed that the<br />

total quantity of milk used for curd was 12.44 litre with the cost of milk of Rs. 39.84.<br />

The revenue received was Rs, 42.47 after sparing 3.35 kg of curd for consumption. The study<br />

of marketing of curd revealed that the farmers are getting low rate profit because of nonremunerative<br />

price of curd.<br />

The study of marketing of Ghee of selected villages of Babina block revealed that total<br />

quantity of milk used forGhee was 6.73 litre <strong>and</strong> total cost of milk was' Rs, 20'39. 1 he<br />

total re venue received of sold Ghee was Rs. 23,40 after sparing 88 g of Ghee for consumption.<br />

The study of marketing of Ghee showed that very little quantity of Ghee was produced <strong>and</strong><br />

marketed in comparison with marketing of curd <strong>and</strong> milk. The stndy of marketing of Khowa<br />

in selected village'> of Babina revealed that the total quantity of milk used fer Khowa was 7.06<br />

litre <strong>and</strong> total cost of milk was Rs. 27.97 after sparing 121 g of Khowa for family consumption.<br />

The study revealed that marketing surplus <strong>and</strong> marketable surplus of khowa in Babina<br />

block were very meagre.<br />

1.3 A study on the economic a,,ct of milk praduction in milkshed areas of Jhansi<br />

district of Bundelkh<strong>and</strong>,<br />

(I. .P. S. Yadav)<br />

The study was conducted in five villages of Baragaon block of Jhansi district. The<br />

study of the socio-economic profile of milk producers revealed that the milkshed area was<br />

dominated by illeterates <strong>and</strong> majority of them depend on agriculture as their principal means<br />

of livelihood. None of house hold had taken up dairying as their main occupation. Majority<br />

of them reared only one/two milch animals <strong>and</strong> they belong to the category of l<strong>and</strong> less<br />

labourers, rrarginal farmers <strong>and</strong> small farmers. The majority of milk producers were aware<br />

of milk production enhancement inputs, their urilization was very poor, which indicated that<br />

milk producers were showing some reluctance towards adopting improved dairying practices.<br />

It may be due to their poor socio-economic background.<br />

( 230 )


The milch animals maintained in the milkshed area were of local type characterised by<br />

low productivity, low lactation length, high dry period <strong>and</strong> later maturity. 'On an average<br />

buffaloes were attaining firstcalving at 46th month <strong>and</strong> cow at 47th month. The total number<br />

of lactations were observed to be six in the case of both cows <strong>and</strong> buffaloes. Theavervge<br />

lactation length was 9 month for cow <strong>and</strong> 10 months for buffaloe, The average dry period<br />

found to be 10 months in the case of cow <strong>and</strong> II months in case ot' buffaloe. Theeve~ag~<br />

yield per day per animal was 1.40 litres in c.ise of cow <strong>and</strong> 2.04 litre in case of buffaloe.<br />

The irrigation facilities in the milkshed areas were inadequate having a significant<br />

bearng on the supply of bovine feed. The bovine feeds are broadly classified nuder three<br />

heads, namely, dry fodder, green fodder <strong>and</strong> concentrates. Only 4 types of dry fodderjnamely,<br />

paddy straw, bajra kadbi, jowar kadbi <strong>and</strong> bhusa were fed to milch animals in the study area.<br />

The major source of green fodder was the local grass <strong>and</strong> weeds. Few farmers were also found<br />

feeding cultivated fodder to their milch animals but.vin general, they showed reluctance to<br />

improve the fodder resources. The quantities of the different types of feed, fed to the milch<br />

animals, was very less conpired to a st<strong>and</strong>ard Ieeuing schedule, AroundS kg of dry fodder,<br />

6 kg of green fodder <strong>and</strong> 0.5 kg of concentrtes were fed per animals per day in case of c0'o/s<br />

in milk <strong>and</strong> 7 kg of dry fodder, 7 kg green fodder <strong>and</strong> 0.75 kg of concentrates per animal per<br />

day in case of buffaloes in milk. The quantities of these three types of feed to dry animals was<br />

almost half of the feed fed to animals in the milkshed area of Jhansi district.<br />

The studies revealed that level of literacy had a very high impact on scientific breeding<br />

<strong>and</strong> management of dairy animals. Inadequate availability of irrigation also had a bearing on<br />

feed supply. Milch animals with a 1.lrge intercalving period, low lactation length <strong>and</strong> low<br />

yie Ids were considered poor.<br />

The average cost of maintenance was Rs. I 65 per day for lactating cow <strong>and</strong> Rs. 0.90<br />

for a dry cow when family labour was included. 'In case of buffaloe, these figures were Rs.<br />

2.14 <strong>and</strong> Rs, 1.11 per day respectively In .het~tal maintenance cost, the major component<br />

was the feed which accounted for 75°1" . of the total maintenance cost for both lactating -cows<br />

. -<br />

<strong>and</strong> buffaloes <strong>and</strong> 60% in case of dry animals. The family labour cost Was onlv around 10%<br />

of the maintenance cost. The returns of dairy enterprise included income from milk, dung <strong>and</strong><br />

sale of calves. The income from milk over the entire life span of a milch animal was Rs,<br />

3590 in case of cow <strong>and</strong> Rs. 6598 in case of buffaloe. The income from the dung during the<br />

entire life span of a milch animal was Rs. 600 in case of cow <strong>and</strong> Rs. 800 in case of buffaloe.<br />

Therefore, the total income from a cow over the entire life span was Rs, 4190, while in case<br />

of buffaloe, it was Rs. 7398,<br />

1,4 Studies on relative economics of forage crop production on cultivators fields.<br />

(Ram Asray Singh)<br />

Studies on the relative economics of the year round fodder production under demonstration<br />

trials through improved technology as compared to the crops (forage or other) grown<br />

by the farmers included the following forage crop rotations in overlapping systems:<br />

1. Berseem+ mustard-s-hybrid napier+ cowpea<br />

1. Berseem+mustard--Setaria sphacelata+cowpea<br />

Three farmers preferred to grow wheat crop <strong>and</strong> two potatoes. The result was overwhelmingly<br />

in favour of cultivation of forage crops in overlapping systems with recommended<br />

package of practices. However, potato crop on one farmer field gave slightly higher than other<br />

crops Rs. 20593.69 (demonstration or farmers crops) but input-c utput ratio was less than<br />

the forage crops berseem-l-rnustard intercropping either wi.h hybrid napier or Setaria<br />

sphacelata,<br />

For rabi 1983-84 Season the forage crop berseem-l-rnustard under demonstration,<br />

yielded on an average 925.15 q /ha of green fodder with a cost of production of Rs. 6239.56<br />

<strong>and</strong> net profit of Rs. 12266.16 perha at prevailing market price (Rs. 20.00). The average<br />

input-output ratio worked out to be 1:2.98.<br />

In demonstration trials of berseern + mustard green forage yield ranged from 753.51 to<br />

1079.00 q/ha <strong>and</strong> the input-output ratio varied from 1:2.47 to 1:3.51. The net profit ranged<br />

from Rs, 8971.30 to Rs. 1438836/ha.<br />

The maximum green forage yield (1079.00 q/ha) was produced with an input of Rs,<br />

7205.44 <strong>and</strong> the net profit of Rs, 14388.36/ha. The input-output ratio was 1:2.09 <strong>and</strong> the cost<br />

of production per quintal green fodder was Rs. 6.67. In all the demonstration trials cost of<br />

production of per quintal green fodder was Rs, 5.68 <strong>and</strong> the minimum cost of production<br />

was Rs, 5142.28/ha. The input output ratio was 1:3.51,<br />

The seed <strong>and</strong> fertilizer irrigation charge, human <strong>and</strong> bullock or tractor power cost<br />

ranged from Rs. 1182,70 to Rs.2130.30; Rs, 1100.00 to Rs. 2000.00 <strong>and</strong> Rs. 1387.50 to<br />

2091.66/ha respectively.<br />

( 232 )


The maximum cost of production per quintal green fodder was Rs, 8.09. It was due to<br />

lower yield (753.51 q/ha) of green forage <strong>and</strong> more irrigation charge Its. 2000.00 per ha,<br />

Irrigations we re done by the diesel pump.<br />

The return obtained from potatoes by the farmers were Rs, 14627.09/ha against Rs.<br />

10952.51/ha under the demonstration crop of berseem+mustard. The input-output ratios<br />

were 1:2.39 <strong>and</strong> ~:2.99 under corresponding systems of cropping. The average yield of potato<br />

on two farmers fields was 250.03 q/ln with tha cost of production of Rs, 11176.36. The<br />

maximum yield of 303.57 q/ha was obtained with the investment of Rs. 9763.31/ha.. This<br />

resulted in a net profit of Rs, 20593.69 <strong>and</strong> input-output ratio of 1:3.10. On the other farmers<br />

field potato yield of 212.50 q/ha was obtained from Rs. 12250.00 as cost of production. This<br />

gave a net profit Rs 8660.50/na. The input-output ratio for this crop was only 1:1.68.<br />

In the case of wheat crop grown by the farmers the grain yield of wheat, ranged from<br />

21.87 to 24.00 q/ha with corresponding input-output ratio of 1:1.19 to 1;1.24. The maximum<br />

net profit was 913.98 per ha <strong>and</strong> the minimurilnet profit was Rs. 695,86/ha. The average cost<br />

of production was Rs, 3723.81/ha <strong>and</strong> the cost per quintal of wheat grain worked out to be<br />

Rs. 125.60. The cost of production of wheat bhusa was Rs. 24.57 per quintal.<br />

1.5 Economics of dairy units in rural <strong>and</strong> urban areas of Gwalior district (M.P.)<br />

(A. K. Sharma)<br />

Most of the sampled families (57.5%) belonged to backward caste co'mml.tllity <strong>and</strong> the<br />

remaining 42.5% were socially advanced caste families. 12.5% families con.sisted oTl-3<br />

members, while 62.5~{ families consisted 4-12 members <strong>and</strong> remaining 25% were big.families<br />

with member ranging from 13 to 21. The study indicated low educational status as 40 dairy<br />

members were illiterate, 22.5% had studied upto primary, 30% either middle pass or secondary,<br />

whereas only 7,5% had studied beyond secondary level.<br />

Family composition of sampled households revealed that percentage of adult <strong>and</strong><br />

children was 44.57% <strong>and</strong> 55.43% in urban area, 52.70% <strong>and</strong> 47.3G% in semi-urban area: <strong>and</strong><br />

51.95% in rural areas, respectively. Percentage of illiteracy is 54.08, 55.44 <strong>and</strong> 51.71 in urban,<br />

semi-urban <strong>and</strong> rural areas respectively. There was no marked difference between different<br />

locations in case of illiteracy as dairy households in urban area, too, have migrated fromrural<br />

areas. Percentage of school going children was 78.91, 92.15 <strong>and</strong> 77.55% in urban semi-urban<br />

<strong>and</strong> rural areas respectively.<br />

11.6 Level <strong>and</strong> pattern of investment on small far~ers in Ajmer district.<br />

(A. K. Sharma <strong>and</strong> D. P. H<strong>and</strong>a)<br />

The study revealed that with the increase in size of holding, total expenditure per farm<br />

increased (from Rs. 5827 to Rs, 12785) whereas per acre capital expenditure diminished<br />

from Rs. 7756 to-Rs, 2174/-). Analysis of different components of fixed capital indicated<br />

that l<strong>and</strong> <strong>and</strong> its improvement was the major component of investment which accounted<br />

57.4% followed by livestock (32.43~~) <strong>and</strong> household property (6.68%), respectively. It has<br />

been found that investment was positively <strong>and</strong> ~ignificantly correlated with irrigation (R=~0.64)<br />

with family size (0.53) with gross annual income (0.36). It has been shown by multiple<br />

234 )


correlation (R=0.80) that irrigation, l<strong>and</strong> holding, family size <strong>and</strong> annual<br />

income was highly<br />

correlated with investment. Multiple regression equation . was Y=34.46+1268.21X +-111865<br />

X 2+225.65<br />

X 3+1.19X4<br />

indicating 64.99% of total variation. Impact of irrigation was higher<br />

in investment as compared to other factors influencing investmeat. .Family size had the least<br />

impact on investment as there was very significant change in variation (Viz. 64.99.%) onexclusion<br />

of family size factor. .<br />

In the uniformity trial, the coefficient of variation for the plot size 1, 2, 3, 4, 6, 8; 9,<br />

12, 16, 18, 24, 27, 36, 48, 54, 74, 108, 144, 162 <strong>and</strong> 216 m 2 were calculated without blocking<br />

<strong>and</strong> also with blocking size of 2, 3, 4, 6, 9, 12, 16, 18,24, 27, The calculated C. V. value<br />

decreased with the increase in plot size in either direction, The C. V, value decreased from<br />

29.90 to 9.02 as plot size increased from I m 2 to 216 m 2• Similar jrend was ,also obtained<br />

with blocking, The average C. v. e;.;) obtained for different plot size with <strong>and</strong> without<br />

blocking showed that there was sharp decline in C. V. value as plot size increased Which<br />

remained upo 9-12 m 2 after that decline was gradual specially when blocking was adc pi~'d,:<br />

2,2 Rainfall pattern <strong>and</strong> their role in forage production in Bundelkh<strong>and</strong>, region.<br />

(D. P. H<strong>and</strong>a)<br />

I, Expected number of dry <strong>and</strong> wet days (Hamirpur)<br />

At Harnirpur, average number of wet <strong>and</strong> dry days were 35.55 <strong>and</strong> 86.45, respectively<br />

with maximum of 44 days in 1971 <strong>and</strong> minimum of 29 in 1964 <strong>and</strong> 1972. The X2 test indicated<br />

significance of 3 years (58 -60) in 15 years indicating weather is not influenced by immediately<br />

preceding -day s weather but also on the weather of immediately two proceeding days.<br />

The 9 years indicated non-significance which implied that we ither of the<br />

day was independent of the wheather of the day proceeding the immediately<br />

preceeding days The variability of wet days remained in the range of 15 to 25.7 of the<br />

mean with the year While from year to year variability of wet days was 15.73%. The probability<br />

11 2 of a unit being wet at the state of equilibrium, was less.than the probability III a<br />

unit being dry at the state of equilibrium' The.same was highest in 1964 for 1I 1=0.7623<br />

<strong>and</strong><br />

1971 11 2 = 0.3607.<br />

2. Expected length of dry runs, wet runs <strong>and</strong> dry wet cycle of one day size (Hamirpur)<br />

The expected length of day rum, wet runs.l<strong>and</strong> dry wet cycle were found out for the<br />

period of 1955 to 1977. The data for the year 1961, 65, 66, 69, 70, 73, 74, 75 were not<br />

available The years 1958-60 years indicated the significance of XLtest which implied that<br />

occurence of wet or dry days was not influenced by the immediately proceeding days weather<br />

but also immediately two preceeding days. The average length of dry run was 5.47 &<br />

wet run was 2.23. The average dry wet cycle was 7.70 units. It was found that expected<br />

length of dry run was always greater than wet run. The variability of dry run from year to<br />

year was 18.70, while of wet run was 18.26 indicating the change more or less same in dryas<br />

well as wet runs.<br />

3. Expected number of wet <strong>and</strong> dry days at Jalaun.<br />

The expected number of wet <strong>and</strong> dry days was 3456 <strong>and</strong> 87.44 respectively. The<br />

maximum number of wet days was 46 in 1967 <strong>and</strong> minimum 21 in 1968. The coefficient of<br />

variability of wet days within the year ranged from 17.20% to 27.35% while be tween the year<br />

it was 23.47%" The X2 test, out of 12 years was found to be significantly different during<br />

1958 <strong>and</strong> 1959. From 1960 to 1977 data was non-significant which indicated weather of<br />

the day was independent of weather of immediately proceeding day. The probability III of<br />

unit dry at the state of equilibrium was greater than II 2 of unit being wet was the state of<br />

equilibrium during all the years.<br />

4. Expected length of dry run. wet run <strong>and</strong> dry wet cycle of one day (Jalaun).<br />

The expected length of dry run wM' found to be 5.20 <strong>and</strong> wet run to be 2.07 compared<br />

to the dry wet cycle of 727 units indicating that after every 5.20 units of dryness there was<br />

wetness. The variability as indicated by st<strong>and</strong>ard deviation of 1.32 in dry run <strong>and</strong> 0.41 in wet<br />

run was not much more. 1958-59 indicated significance of X 2 test mean occurrence of wet<br />

dry day is not influenced.<br />

5. Weather analysis ana climatological classification of B<strong>and</strong>a district.<br />

(D. P. H<strong>and</strong>a <strong>and</strong> R. M. Sood)<br />

From the climate' of this place it was seen that th e July <strong>and</strong> August was most wet<br />

period where water surplus measured as 42.85 <strong>and</strong> 49.32 mm, respectively <strong>and</strong> rest the 10<br />

months were in deficit to the tune of about 431 mm <strong>and</strong> 378 mm, respectively, The probability<br />

analysis indicated that the maximum weekly rainfall which could be expected with 50%<br />

probability in the month of June, July, August <strong>and</strong> September was 41, 116, 135 <strong>and</strong> 63 mm<br />

respectively <strong>and</strong> also maximum weekly rainfall which could be expeeted with 50% probabilities<br />

in their st<strong>and</strong>ard week of June 32 mm, July 71 mm, 107 mm in August <strong>and</strong> 34 mm in<br />

September.<br />

Plant exploration <strong>and</strong> collection'<br />

The plant exploration <strong>and</strong> collection trip was made to collect the germplasm of fodder<br />

crops from various places in Ladkh region. Gerrnplasm of crops like wheat, bariey, Setaria<br />

<strong>and</strong> Lathyrus were also collected to evaluate these at the lower elevations in Kashmir valley.<br />

The present collection activities were confined to the Indus, Dras <strong>and</strong> Zanskar valleys<br />

only. Most of the agricultural activity in the region is confined to these areas. The vegetation<br />

cover is only 5% <strong>and</strong> the agriculture is totally irrigated. All the agricultural acti vity is<br />

confined along Indus <strong>and</strong> Suru Rivers.<br />
