Central Rice Research Institute Annual report...2011-12

of Rs. 30,100. Replacement of transplanted Sita with
Sahbhagidhan allowed the farmers to increase the cropping
intensity (rapeseed var. PT 303 after rice harvest)
and securing a net return of Rs. 30,500.
Balanced fertilizer application (NPK: 120:100:90
over farmers practice of 60:30:00) improved the tuber
size and the yield in potato by 34% resulting into a net
return of Rs. 83,600 besides, reducing the incidence of
disease/insect pests. Application of Azotobacter and
PSB @ 25 kg ha -1 and 5 kg ha -1 , respectively in conjunction
with 75% of the recommended dose of fertilizer
(NPK 100:50:25) in wheat (var. UP 262) yielded 37.4%
more (3.73 t ha -1 ) over farmers’ practice (2.73 t ha -1 ).
OFT of new varieties of capsicum (Indra), wet season
onion (Arka Niketan) and papaya (Pusa Nanha) were
also conducted. Deworming thrice in a year to increase
the body weight of goat, calcium @ 30 ml per day for 60
days to increase milk production in cows, zero energy
cool chambers to reduce weight loss and spoilage of
fresh vegetables, bamboo platform for housing of goats
were the other technologies evaluated under OFT and
were found suitable for the district.
Front Line Demonstrations (FLDs)
Front line demonstrations of transplanted
Sahbhagidhan in rainfed conditions recorded 37.2%
more yield (3.5 t ha -1 ) as compared to the local check.
Farmers reported higher number of tillers hill -1 , spikelets
panicle -1 and higher filled grain percentage. Pigeon
pea variety Maruti was liked by the farmer as it had
bold grains that fetched higher price in the market but
occasional incidence of wilt (upto 10%) was noticed in
the FLDs. Birsa Niger 1 and rapeseed variety Shivani
were also demonstrated after rice harvest.
Training and Seed Production
KVK conducted 72 on and off campus training
programes in areas like Technique of seed treatment in
rice, Nursery management of kharif season vegetable,
Management of milch cattle in summer season, Care
and management in goat, Scientific method for preservation
of seasonal fruit, Improved paddy cultivation
for different farming situation, IPM in okra, technique
of seed treatment in kharif pulses, Technique for increasing
cropping intensity in rice-fallow system, Making
different types of papad and chips, Lac cultivation,
Formation of self-help group, Technique of micro-irrigation
in vegetable crops, Establishment of layout technique
in orchard and Scientific cultivation of kharif
onion during 2011-12 benefiting 1736 farmers. Farmers
produced 40.4 q of seeds of rice varieties Abhishek,
Anjali and Sahbhagidhan (seed village), while, KVK
produced good quantity of planting materials of various
crops and vermicompost in the technology demonstration
farm.
