RICE IN KARNATAKA<br />
I. Name of the state : <strong>Karnataka</strong><br />
II. Introducti<strong>on</strong><br />
The <strong>Karnataka</strong> state, a regi<strong>on</strong> <strong>in</strong>habited predom<strong>in</strong>antly by Kannada speak<strong>in</strong>g people, is<br />
situated between 11 0 31’ and 18 0 45’ North latitude and 74 0 12’ and 78 0 40’ East l<strong>on</strong>gitude and<br />
lies <strong>in</strong> the west-central part of pen<strong>in</strong>sular India. Its maximum spread from north to south is<br />
about 700 km and from east to west 400 km. It is bound <strong>on</strong> the north by Maharashtra state, <strong>on</strong><br />
the northeast by Goa, <strong>on</strong> the east by Andhra Pradesh, <strong>on</strong> the south and southeast by Tamil<br />
Nadu, <strong>on</strong> the southwest by Kerala with a coastl<strong>in</strong>e border<strong>in</strong>g the Arabian Sea. The state with<br />
geographical area of around 1.91 lakh sq km is the eighth largest <strong>in</strong> the country. It has a variety<br />
of topographical situati<strong>on</strong>s rang<strong>in</strong>g from the coastal pla<strong>in</strong>s to gentle slopes and culm<strong>in</strong>at<strong>in</strong>g <strong>in</strong><br />
the spectacular heights of the Western Ghats.<br />
Elevati<strong>on</strong>s <strong>in</strong> various parts do not vary greatly though the abruptness with which they<br />
change is marked <strong>in</strong> some parts as between the narrow coastal strip that rarely exceeds a width<br />
of 30 km and the equally narrow Western Ghats immediately adjo<strong>in</strong><strong>in</strong>g the coastal pla<strong>in</strong>s.<br />
Greater part of <strong>Karnataka</strong> lies between 450 and 900 meters above mean sea level. In<br />
places, however, the elevati<strong>on</strong> reaches over 1,800 meters, <strong>in</strong> Bababudan (Chandradr<strong>on</strong>a<br />
Parvatha) ranges followed by Kudremukh at 1,892 meters. The general elevati<strong>on</strong> of this table<br />
land is about 600 meters but <strong>in</strong> central parts it is c<strong>on</strong>siderably higher at places between the<br />
Krishna and Cauvery river systems particularly <strong>in</strong> Chikmagalur, Kodagu and Hassan districts.<br />
The districts of <strong>Karnataka</strong> are shown <strong>in</strong> Figure 1.<br />
<strong>Karnataka</strong> is blessed with abundant water wealth with as many as seven major rivers and<br />
a number of rivulets and streams. The important rivers are Sharavathi, Kali, Nethravathi, Varahi,<br />
Bedthi, Aghansani, Krishna, Ghataprabha, Malaprabha, Bhima, Tungabhadra and Cauvery. These<br />
rivers swell <strong>in</strong> m<strong>on</strong>so<strong>on</strong>s and a majority of them take out <strong>in</strong>to mere trickle after the m<strong>on</strong>so<strong>on</strong>s.<br />

The total catchment area of these river bas<strong>in</strong>s is 1, 91,773 sq km and the estimated<br />
average flow is 97,800 M cum. The Krishna and Cauvery river bas<strong>in</strong>s together dra<strong>in</strong> as much as<br />
77 per cent of the geographical area of the state.<br />
Groundwater <strong>in</strong> the state occurs under water table c<strong>on</strong>diti<strong>on</strong>s, under the hard rocks<br />
which have become sufficiently porous to hold moderate quantities of ground water. The<br />
groundwater utility estimates reveal that the overall utilizati<strong>on</strong> of groundwater <strong>in</strong> the state was<br />

Z<strong>on</strong>al Informati<strong>on</strong><br />
a. Climate:<br />
Ra<strong>in</strong>fall and its distributi<strong>on</strong> pattern: The climate of <strong>Karnataka</strong> is basically tropical and<br />
determ<strong>in</strong>ed largely by the physiographic and geographic locati<strong>on</strong> with respect to the sea and<br />
m<strong>on</strong>so<strong>on</strong>. The state enjoys the benefit of two m<strong>on</strong>so<strong>on</strong>s and hence can well be called the land<br />
of the two seas<strong>on</strong>s, because both the south-west and north-east m<strong>on</strong>so<strong>on</strong>s account for major<br />
part of the ra<strong>in</strong>fall. A small quantity of ra<strong>in</strong>fall is received dur<strong>in</strong>g cold and hot weather seas<strong>on</strong>s.<br />
The state receives an average annual ra<strong>in</strong>fall of 1354.7 mm with a m<strong>in</strong>imum of 552.8 mm<br />
and a maximum of 3932.4 mm. The analysis of data over two decades reveals that, of the<br />
average ra<strong>in</strong>fall of the state, 9991.7 mm is received <strong>in</strong> the south-west m<strong>on</strong>so<strong>on</strong> (June to<br />
September), 212.4 mm from the north-east m<strong>on</strong>so<strong>on</strong> (October to December), 142.3 mm <strong>in</strong> hot<br />
weather period (March to May), while, hardly 8.3 mm is received <strong>in</strong> the cold weather period<br />
(January to February).<br />
In terms of percentage c<strong>on</strong>tributi<strong>on</strong> <strong>in</strong> the four seas<strong>on</strong>s, south-west m<strong>on</strong>so<strong>on</strong><br />
c<strong>on</strong>tributes a maximum of 73 per cent, followed by north-east m<strong>on</strong>so<strong>on</strong>, hot weather and cold<br />
weather periods account<strong>in</strong>g for 16, 10 and 1 per cent, respectively.<br />
The distributi<strong>on</strong> of annual and seas<strong>on</strong>al ra<strong>in</strong>fall over <strong>Karnataka</strong> state <strong>in</strong>dicates that it is<br />
the highest over the Western Ghats and the lowest <strong>in</strong> the eastern parts of Chitradurga districts.<br />
The ra<strong>in</strong>fall <strong>in</strong> the coastal regi<strong>on</strong> exceeds 3000 mm, the western ghats <strong>in</strong>clud<strong>in</strong>g Malnad regi<strong>on</strong><br />
receives an annual ra<strong>in</strong>fall rang<strong>in</strong>g from 4000 to 8000 mm, the northern maidan regi<strong>on</strong> receives<br />
from 1500 to 500 mm, decreas<strong>in</strong>g from west to east and the southern maidan receives an<br />
annual ra<strong>in</strong>fall from 2000 mm <strong>in</strong> the west to around 460 mm <strong>in</strong> the eastern edge <strong>in</strong> Chitradurga<br />
district.<br />
Temperature: Temperature is the lowest <strong>in</strong> January and <strong>in</strong>creases thereafter gradually at<br />
first and rapidly after the middle of February or beg<strong>in</strong>n<strong>in</strong>g of March. In the southern maidan<br />
regi<strong>on</strong>, the highest temperature occur <strong>in</strong> April, while, <strong>in</strong> the northern maidan and coastal area<br />
they occur <strong>in</strong> May. In January, the mean daily maximum temperature is 31 0 C <strong>in</strong> the coastal area<br />
and slightly above 30 0 C <strong>in</strong> the northern maidan area except <strong>in</strong> Bidar district where it is 28 to 29 0<br />
C. Over the western Ghat areas, it is 24 0 to 27 0 C. In April, the mean daily maximum<br />

temperature is about 32 0 C <strong>in</strong> the coastal regi<strong>on</strong> and <strong>in</strong>creases as we go north-eastwards <strong>in</strong> the<br />
northern maidan area to 39 0 C <strong>in</strong> Gulbarga-Raichur regi<strong>on</strong> and decreases to about 37 0 C <strong>in</strong> Bidar<br />
area. Over the rest of the maidan area it is 28 to 32 0 C.<br />
The highest maximum temperature is <strong>in</strong> May, which is the warmest m<strong>on</strong>th over major<br />
part of the state, reaches 43 0 C <strong>in</strong> Gulbarga - Raichur regi<strong>on</strong>. It exceeds 40 0 C <strong>in</strong> the area northeast<br />
of a l<strong>in</strong>e jo<strong>in</strong><strong>in</strong>g Bidar, Gadag and Bellary. It is 35 0 C to 36 0 C over the coastal area and 36 0 C<br />
to 38 0 C over the southern maidan area. Over the Western Ghats and malnad area, it is 32 0 C to<br />
34 0 C. Temperature decreases after May, and by July the daily maximum temperature decreases<br />
appreciably. The warmest regi<strong>on</strong> <strong>in</strong> July, is Bellary-Raichur-Gulbarga area where the mean daily<br />
maximum temperature is about 32 0 C. It decreases to 29 0 C towards Bidar. It is about 28 0 C <strong>in</strong><br />
the coastal area and <strong>in</strong>creases north-eastwards to 32 0 C <strong>in</strong> Raichur-Gulbarga area. In the<br />
southern maidan the maximum temperature is 26 0 C to 27 0 C. In the ghats and malnad area, it is<br />
about 20 to 24 0 C. It is of <strong>in</strong>terest to note that after October, temperature gradually decreases<br />
throughout the state reach<strong>in</strong>g the lowest <strong>in</strong> early January.<br />
Humidity: The average relative humidity is the highest <strong>in</strong> the state dur<strong>in</strong>g July-August<br />
and lowest <strong>in</strong> March-April. Relative humidity depends not <strong>on</strong>ly <strong>on</strong> the amount of water vapour<br />
<strong>in</strong> the atmosphere but also <strong>on</strong> temperature. In general the coastal area, ghats and Malnad areas<br />
are more humid than the Maidan areas. Southern maidan areas are comparatively more humid<br />
than the northern maidan areas. The regi<strong>on</strong> hav<strong>in</strong>g the lowest m<strong>on</strong>thly relative humidity of<br />
about 30 per cent <strong>in</strong> April-May is that extend<strong>in</strong>g from northern Chitradurga and Bellary districts<br />
to Bijapur districts to Bijapur, Raichur and Gulbarga districts. Humidity is as low as 5 to 10 per<br />
cent, and sometimes even less <strong>in</strong> this area <strong>in</strong> the afterno<strong>on</strong> hours <strong>in</strong> summer. Even <strong>in</strong> the<br />
southern maidan area, low relative humidity of 10 to 20 per cent may be recorded dur<strong>in</strong>g the<br />
afterno<strong>on</strong> <strong>in</strong> March-April. In July and August very high humidity exceed<strong>in</strong>g 90 per cent occur<br />
over the coastal area, ghats and malnad areas, and 80 to 60 per cent over the rest of the state.<br />
From September <strong>on</strong>wards, humidity generally decreases gradually upto November and rapidly<br />
thereafter.<br />

b. Soil type :<br />
<strong>Karnataka</strong> state represents a wide variety of geological, climatic, vegetati<strong>on</strong>al and<br />
physiographic features, which have <strong>in</strong>fluenced soil formati<strong>on</strong> and thus given rise to various types<br />
of soils. Accord<strong>in</strong>gly, the different soils have dist<strong>in</strong>ct morphological and physic-chemical<br />
properties that have a bear<strong>in</strong>g <strong>on</strong> plant growth and have <strong>in</strong>fluenced the cropp<strong>in</strong>g pattern, giv<strong>in</strong>g<br />
a unique status to the state. A scientific knowledge of soils is a pre-requisite to understand the<br />
local ecology and useful <strong>in</strong> plann<strong>in</strong>g for agricultural development.<br />
As per the updated soil survey data, the soils of <strong>Karnataka</strong> have been broadly classified<br />
under n<strong>in</strong>e groups. The characteristics and distributi<strong>on</strong> of these n<strong>in</strong>e soil groups <strong>in</strong> different<br />
parts of <strong>Karnataka</strong> are as follows:<br />
1. Shallow Black Soils<br />
These soils are usually encountered <strong>on</strong> undulat<strong>in</strong>g ridges <strong>in</strong> the Deccan trap regi<strong>on</strong> and to<br />
some extent <strong>on</strong> schist and lime st<strong>on</strong>e upland regi<strong>on</strong> of <strong>Karnataka</strong>, occupy<strong>in</strong>g areas <strong>in</strong> north and<br />
north-west parts of the districts of Belgaum, Bijapur, Gulbarga and Bidar.<br />
These are shallow (less than 23 cm), dark greyish brown, dark brown to dark reddish<br />
browm, usually calcareous, with gravelly clay loam to clay <strong>in</strong> texture. They are neutral to weakly<br />
alkal<strong>in</strong>e and have moderate to high water hold<strong>in</strong>g capacity with high cati<strong>on</strong> exchange capacity<br />
(CEC). The soils are well dra<strong>in</strong>ed to some-what excessively dra<strong>in</strong>ed with moderate permeability.<br />
The clay m<strong>in</strong>eral is dom<strong>in</strong>antly m<strong>on</strong>tmorill<strong>on</strong>itic. These soils are classified under the orders<br />
Entisols and <strong>in</strong>ceptisols with sub-orders Orthents and Ochrepts.<br />
Suitable soil and water c<strong>on</strong>servati<strong>on</strong> measures al<strong>on</strong>g with adopti<strong>on</strong> of package of<br />
practices are essential to obta<strong>in</strong> satisfactory crop yields. Care is essential while, develop<strong>in</strong>g<br />
these lands for irrigati<strong>on</strong> due to their shallow depth and steep slopes.<br />

2. Medium Black Soils<br />
These soils usually occur <strong>in</strong> the Deccan trap, schist, lime st<strong>on</strong>e and shale regi<strong>on</strong> of the<br />
state, occupy<strong>in</strong>g areas <strong>in</strong> parts of Bidar, Gulbarga, Bijapur and Belgaum districts and to some<br />
extent <strong>on</strong> pen<strong>in</strong>sular gneiss area <strong>in</strong> Raichur, Chitradurga and Dharwad districts.<br />
These soils are moderately deep to very deep (23-90 cm), dark to very dark <strong>in</strong> greyish<br />
brown, dark reddish brown or black <strong>in</strong> colour, usually calcareous, crack<strong>in</strong>g, clayey soils. These<br />
are highly moisture retentive, neutral to alkal<strong>in</strong>e, and well supplied with bases. They c<strong>on</strong>ta<strong>in</strong><br />
high percentage of clay dom<strong>in</strong>ated by m<strong>on</strong>tmorill<strong>on</strong>itic type of m<strong>in</strong>eral. These are moderately<br />
well dra<strong>in</strong>ed with slow permeability. Heavy crack<strong>in</strong>g <strong>in</strong> dry periods, typical wedge shaped blocky<br />
structure and prom<strong>in</strong>ent slickensides <strong>in</strong> the sub-surface horiz<strong>on</strong>s are quite comm<strong>on</strong>. The soils<br />
are classified under the orders Inceptisols and Vertisols with sub-orders Ochrepts and Usterts.<br />
The soils are fertile and produce good yields when moisture is not limit<strong>in</strong>g but modera -<br />
tely susceptible to erosi<strong>on</strong>.<br />
Adequate soil and water c<strong>on</strong>servati<strong>on</strong> measures al<strong>on</strong>g with adopti<strong>on</strong> of package of<br />
practices are essential to obta<strong>in</strong> susta<strong>in</strong>ed high yields. Indiscrim<strong>in</strong>ate use of water may lead to<br />
development of sal<strong>in</strong>ity, alkal<strong>in</strong>ity and water logg<strong>in</strong>g problems.<br />
3. Deep Black Soils<br />
These soils occur <strong>in</strong> Deccan trap lime st<strong>on</strong>e regi<strong>on</strong>s, <strong>in</strong> parts of Gulbarga, Bijapur and<br />
Belgaum districts and c<strong>on</strong>siderable areas <strong>in</strong> parts of Raichur, Bellary, Dharwad, Chitradurga, and<br />
Mysore districts.<br />
These are very deep (more than 90 cm), dark brown, dark greyish brown to very dark<br />
grey or black <strong>in</strong> colour. The texture is usually clayey throughout the profile. These are<br />
calcareous and are weakly to str<strong>on</strong>gly alkal<strong>in</strong>e, highly crack<strong>in</strong>g m<strong>on</strong>tmorill<strong>on</strong>itic clayey soils.<br />

These are highly moisture retentive and moderately well dra<strong>in</strong>ed to imperfectly dra<strong>in</strong>ed<br />
with low to very low permeability. A loose, crumb to granular surface mulch, gilgai micro relief,<br />
prom<strong>in</strong>ent <strong>in</strong>tersect<strong>in</strong>g slickensides and typical sub-angular to angular blocky structure are<br />
comm<strong>on</strong> <strong>in</strong> these soils. These soils are classified under the order Vertisols with sub-order<br />
Usterts.<br />
These soils are fertile and generally produce good yields when moisture is not a limit<strong>in</strong>g<br />
factor but are slight to moderately susceptible to erosi<strong>on</strong>.<br />
Adequate soil and water c<strong>on</strong>servati<strong>on</strong> measures, appropriate provisi<strong>on</strong> of dra<strong>in</strong>age<br />
facilities especially <strong>in</strong> the low lands and adopti<strong>on</strong> of package of practices are essential to obta<strong>in</strong><br />
susta<strong>in</strong>ed high yields under ra<strong>in</strong>fed cultivati<strong>on</strong>. Indiscrim<strong>in</strong>ate use of water <strong>on</strong> these soils could<br />
spoil the soil structure and lead to sal<strong>in</strong>ity and water logg<strong>in</strong>g problems.<br />
4. Red Sandy Soils<br />
These soils occur <strong>on</strong> undulat<strong>in</strong>g landscape <strong>on</strong> acidic rock viz. Granites and granite<br />
gneisses, occupy<strong>in</strong>g areas <strong>in</strong> parts of Dharwad, Bellary, Chitradurga, Shimoga, Bangalore,<br />
Tumkur, Mandya and Mysore districts of the State.<br />
The soils of this type can further be sub-divided <strong>in</strong>to the follow<strong>in</strong>g three groups occupy<strong>in</strong>g <strong>on</strong><br />
dist<strong>in</strong>ct topographic sites with vary<strong>in</strong>g physicochemical properties.<br />
a) Upland<br />
b) Midland, and<br />
c) Low land soils<br />
These are usually situated <strong>on</strong> c<strong>on</strong>vex ridges with 3-5 per cent gradient or more. The soils are<br />
shallow to moderately deep, reddish brown to dark reddish brown, gravelly loamy sand to sandy<br />
loam <strong>on</strong> the surface with sandy loam to gravelly sand clay <strong>in</strong> the sub-surface horiz<strong>on</strong>s. They are<br />
neutral to slightly acidic <strong>in</strong> reacti<strong>on</strong> and low <strong>in</strong> cati<strong>on</strong> exchange capacity, base saturati<strong>on</strong> and<br />
water hold<strong>in</strong>g capacity but well dra<strong>in</strong>ed with rapid permeability.<br />

RICE IN KARNATAKA<br />
These soils are classified under the orders Entisols, Inceptisols and Alfisols with sub-orders,<br />
Orthents, Ochrepts and Ustalfs.<br />
Though these soils resp<strong>on</strong>d well to irrigati<strong>on</strong>, manur<strong>in</strong>g and other management practices,<br />
the yields are very low due to low fertility status, shallow root<strong>in</strong>g depth and <strong>in</strong>adequate storage<br />
soil moisture capacity.<br />
Adequate storage soil moisture c<strong>on</strong>servati<strong>on</strong> measures, comb<strong>in</strong>ed with adequate applicati<strong>on</strong><br />
of organic manures to improve soil structure, fertility and water hold<strong>in</strong>g capacity are essential to<br />
obta<strong>in</strong> satisfactory yields under ra<strong>in</strong>fed cultivati<strong>on</strong>.<br />
Soils of Midlands<br />
These soils occur <strong>on</strong> gently slop<strong>in</strong>g midlands <strong>in</strong> gneissic complex regi<strong>on</strong>. These are deep<br />
to very deep, reddish brown to dark reddish brown, loamy sand to sandy loam or sandy clay<br />
loam <strong>on</strong> the surface with sandy clay to gravelly clay <strong>in</strong> the sub-surface horiz<strong>on</strong> with well<br />
developed argillic (clay rich) horiz<strong>on</strong>. They are neutral to acidic <strong>in</strong> reacti<strong>on</strong> and low to medium <strong>in</strong><br />
cati<strong>on</strong> exchange capacity and base saturati<strong>on</strong> with medium to high water hold<strong>in</strong>g capacity. The<br />
clay is dom<strong>in</strong>ated with Kaol<strong>in</strong>ite and hydrous oxides of ir<strong>on</strong> and alum<strong>in</strong>ium. The soils are well<br />
dra<strong>in</strong>ed with moderate permeability. These soils are classified under the order Alfisols with suborder<br />
Ustalfs.<br />
The yields obta<strong>in</strong>ed <strong>on</strong> these soils are generally good when moisture is not limit<strong>in</strong>g. They<br />
also resp<strong>on</strong>d well to irrigati<strong>on</strong>, manur<strong>in</strong>g and other management practices. Adequate soil and<br />
moisture c<strong>on</strong>servati<strong>on</strong> measures and adopti<strong>on</strong> of package of practices are recommended to<br />
obta<strong>in</strong> susta<strong>in</strong>ed high yields.<br />
Soils of Low Lands<br />
These are partially deposited soils occurr<strong>in</strong>g <strong>on</strong> very gentle slope to nearly level or flat<br />
valley bottom areas, are deep to very deep, dark brown to very dark brown, sandy loam sandy<br />
clay loamand occasi<strong>on</strong>ally clay loam soils <strong>on</strong> the surface and sandy clay loam to clayey soils <strong>in</strong><br />

the sub-surface horiz<strong>on</strong>s. They are neutral to weakly alkal<strong>in</strong>e, n<strong>on</strong>-calcarious to calcarious and<br />
have medium to high cati<strong>on</strong> exchange capacity and base saturati<strong>on</strong>. The water hold<strong>in</strong>g capacity<br />
is relatively high. These soils are moderately well dra<strong>in</strong>ed to poor dra<strong>in</strong>age with moderately low<br />
to low permeability. At places the ground water table is seen with<strong>in</strong> 1.5. to 2.0 meters for a<br />
good part of the year. Patches of sal<strong>in</strong>e and alkal<strong>in</strong>e areas also occur <strong>in</strong> the low lands. These<br />
soils are classified under the order Alfisols and Entisols with sub-orders Ustalfs and Fluvents.<br />
These soils normally resp<strong>on</strong>d to irrigati<strong>on</strong>, manur<strong>in</strong>g and other management practices<br />
and generally good yields are obta<strong>in</strong>ed <strong>on</strong> these soils.<br />
Adequate dra<strong>in</strong>age and adopti<strong>on</strong> of recommended package of practices can ensure<br />
susta<strong>in</strong>ed yields. In problematic areas like high water table and water logg<strong>in</strong>g, encouragement<br />
for digg<strong>in</strong>g wells <strong>in</strong> the command may help <strong>in</strong> reduc<strong>in</strong>g the water table. Also, soil amendments<br />
may be added accord<strong>in</strong>g to the soil test results to reclaim soils affected by alkal<strong>in</strong>ity.<br />
5. Mixed Red and Black Soils<br />
These soils usually occur <strong>on</strong> gently undulat<strong>in</strong>g pla<strong>in</strong> or complex geological material<br />
compris<strong>in</strong>g of gneisses. This type of soil occupies areas <strong>in</strong> parts of Bijapur, Dharwad, Belgaum,<br />
Raichur, Bellary and Chitradurga districts.<br />
Usually red soils resemble the red sandy soils of midland regi<strong>on</strong> <strong>in</strong> physic-chemical<br />
properties and black soils resemble the medium and deep black soils <strong>in</strong> physic-chemical<br />
characteristics. These soils are classified under the orders Alfisols, Vertisols and Entisols with<br />
sub-orders Ustalfs, Usterts and Orthents.<br />
The soils are productive, when moisture is not limit<strong>in</strong>g. Care is essential for develop<strong>in</strong>g<br />
these lands for irrigati<strong>on</strong>. Provisi<strong>on</strong> of dra<strong>in</strong>age especially <strong>in</strong> the low ly<strong>in</strong>g areas is essential<br />
while, plann<strong>in</strong>g for irrigati<strong>on</strong>. Use of good quality irrigati<strong>on</strong> water and its judicious applicati<strong>on</strong>,<br />
applicati<strong>on</strong> of liberal quantities of organic manures, and careful management are<br />
recommended.<br />

The measures suggested for problematic areas <strong>in</strong> deep black soils are also applicable to<br />
the problematic areas like sal<strong>in</strong>e, alkal<strong>in</strong>e and water logged areas under these soils.<br />
6. Red Loamy Soils<br />
These soils occur <strong>on</strong> hilly to undulat<strong>in</strong>g landscape <strong>on</strong> granites, granitic gneisses and<br />
Dharwad schists, occupy<strong>in</strong>g areas as a l<strong>on</strong>g strip al<strong>on</strong>g the western ghats <strong>in</strong> the transiti<strong>on</strong>al z<strong>on</strong>e<br />
compris<strong>in</strong>g western parts of Belgaum, Uttara Kannada, Shimoga, Chitradurga, Udupi, Mangalore,<br />
Hassan and Kodagu districts and parts of Chitradurga, Tumkur, Kolar and Bangalore districts.<br />
The soils of this regi<strong>on</strong> can further be sub-divided <strong>in</strong>to the follow<strong>in</strong>g three groups<br />
occurr<strong>in</strong>g <strong>on</strong> dist<strong>in</strong>ct physiographic positi<strong>on</strong> and have vary<strong>in</strong>g physico-chemical properties.<br />
a) Upper slops<br />
b) Undulat<strong>in</strong>g mid-slopes and<br />
c) Valley pla<strong>in</strong> soils.<br />
Soils of Upper Slopes<br />
These are usually situated <strong>on</strong> c<strong>on</strong>vex ridges and steep side slopes. The soils are shallow<br />
to moderately deep, light grey, yellowish red and str<strong>on</strong>g brown gravelly sandy loam to sandy<br />
loam soils. They are normal to weakly acidic <strong>in</strong> reacti<strong>on</strong> and low <strong>in</strong> CEC, base saturati<strong>on</strong> and<br />
water hold<strong>in</strong>g capacity. These soils are classified under the orders Entisols and <strong>in</strong>ceptisols with<br />
sub-orders Orthents and Ochrepts. The soils have low fertility status with shallow root<strong>in</strong>g depth<br />
and low water hold<strong>in</strong>g capacity. Care should be taken to develop these lands for irrigati<strong>on</strong> due<br />
to their soil depth, coarse texture and steeper slopes. The soils may be restricted to light<br />
irrigated crops due to high percolati<strong>on</strong> losses. Applicati<strong>on</strong> of liberal quantities of organic<br />
manure is recommended.<br />
Soils of Undulat<strong>in</strong>g Mid Slopes<br />
These soils occur <strong>on</strong> sleepy to gently slop<strong>in</strong>g undulat<strong>in</strong>g to hilly landscape. The soils are<br />
very deep, dark brown to dark red, sandy loam to clay loam <strong>on</strong> the surface and loam to clay<br />

c. Agro-climatic z<strong>on</strong>es<br />
Based <strong>on</strong> the ra<strong>in</strong>fall pattern, topography, soil characteristics, climate <strong>in</strong> general and<br />
cropp<strong>in</strong>g patterns, <strong>Karnataka</strong> state has been divided <strong>in</strong>to ten dist<strong>in</strong>ct agro-climatic z<strong>on</strong>es which<br />
serve as focal areas for c<strong>on</strong>duct<strong>in</strong>g locati<strong>on</strong> specific research (An<strong>on</strong>ymous 1993). The ten agroclimatic<br />
z<strong>on</strong>es of the state are North-eastern transiti<strong>on</strong> z<strong>on</strong>e, North-eastern dry z<strong>on</strong>e, Northern<br />
dry z<strong>on</strong>e, Central dry z<strong>on</strong>e, Eastern dry z<strong>on</strong>e, Southern dry z<strong>on</strong>e, Southern transiti<strong>on</strong> z<strong>on</strong>e,<br />

IV.<br />
<strong>Rice</strong> producti<strong>on</strong> scenario:<br />
In <strong>Karnataka</strong> rice is grown under a variety of soils and wide range of ra<strong>in</strong>fall and<br />
temperature. Only around 44 per cent of the total acreage is under irrigati<strong>on</strong> while the rest is<br />
under the regime of m<strong>on</strong>so<strong>on</strong>. <strong>Rice</strong> is cultivated <strong>in</strong> places where the ra<strong>in</strong>s are as heavy as 3000<br />
mm and <strong>in</strong> others where it is just 600 mm. In some areas <strong>on</strong>ly <strong>on</strong>e crop is grown and <strong>in</strong> certa<strong>in</strong><br />
other areas three crops are raised. The unique feature of rice culture <strong>in</strong> the state is that either<br />
sow<strong>in</strong>g or transplant<strong>in</strong>g is seen <strong>in</strong> all seas<strong>on</strong>s of the year. The durati<strong>on</strong> of the rice varieties<br />
cultivated <strong>in</strong> the state varies from 100 to 180 days depend<strong>in</strong>g <strong>on</strong> seas<strong>on</strong> and agro-climatic<br />
locati<strong>on</strong>.<br />
V. Regi<strong>on</strong>-wise <strong>Rice</strong> grow<strong>in</strong>g ecosystems<br />
In <strong>Karnataka</strong> it is highly challeng<strong>in</strong>g for the researchers to work with the problems of<br />
diversified rice cultivati<strong>on</strong>. Based <strong>on</strong> the agro-climatic situati<strong>on</strong>, amount and distributi<strong>on</strong> of<br />
ra<strong>in</strong>fall, soil type and prevail<strong>in</strong>g agro-climatic practices, rice grow<strong>in</strong>g ecosystems of the state can<br />
be broadly classified <strong>in</strong>to follow<strong>in</strong>g six categories.<br />
1. Coastal area: A major area of nearly 0.21 m ha of rice is covered by the coastal area with<br />
the productivity of 2.9 t/ha. This area comprises the entire district of Udupi and Mangalore as<br />
well as part of Uttar Kannada district. This area enjoys very good annual ra<strong>in</strong>fall of about 3600<br />
mm. The rice soils are mostly laterites with poor fertility and are generally deficient <strong>in</strong> lime. It<br />
has three ma<strong>in</strong> rice seas<strong>on</strong>s. In the first crop seas<strong>on</strong>,<br />

December. It is ma<strong>in</strong>ly an irrigated crop. In this regi<strong>on</strong>, varieties with coarse gra<strong>in</strong> and red<br />
kernels are generally preferred for parboil<strong>in</strong>g. The major c<strong>on</strong>stra<strong>in</strong>ts <strong>in</strong> the regi<strong>on</strong> are scarcity of<br />
labours, leach<strong>in</strong>g of nutrients, <strong>in</strong>frastructures, soil acidity, crop damage by wild animals, erratic<br />
ra<strong>in</strong>fall, gall midge, blast and seas<strong>on</strong>al floods.<br />
2. Hilly area: A total of 0.26 m ha is under rice with the productivity of 1.98 t/ha. The hill<br />
regi<strong>on</strong> which <strong>in</strong>cludes Coorg, Chikmagalur and parts of Hassan district is completely under the<br />
regime of m<strong>on</strong>so<strong>on</strong>. The area receives ra<strong>in</strong>fall from May to October. The annual precipitati<strong>on</strong> of<br />
this regi<strong>on</strong> is around 1600 mm or higher. The temperature variati<strong>on</strong> is also much greater (13 o c<br />
to 36 o c) <strong>in</strong> hilly regi<strong>on</strong> than <strong>in</strong> other regi<strong>on</strong>s of the state. Soils are mostly laterites, poor <strong>in</strong> lime<br />
and acid <strong>in</strong> reacti<strong>on</strong>. In the eastern parts of Chikmagalur district red soils of sandy to loamy<br />
texture occur. The ma<strong>in</strong> rice seas<strong>on</strong> is from June-July to November-December. <strong>Rice</strong> is grown<br />
either transplanted or broadcast. The toposequence of land situati<strong>on</strong> limits the choice of<br />
varieties, with different durati<strong>on</strong> (145 to 180 days). In most hilly areas, rice is grown <strong>on</strong>ly <strong>on</strong>ce a<br />
year. In the uplands of this hilly area rice is direct seeded <strong>on</strong> a c<strong>on</strong>siderable area. This class of<br />
rice is sown <strong>in</strong> May-June and harvested <strong>in</strong> September-October.<br />
3. Transiti<strong>on</strong>al area: This is the drill sown rice area, compris<strong>in</strong>g Belgaum, Dharwar and parts<br />
of North canara districts. It has a total of 0.19 m ha. (14.4 per cent of the area under rice) with<br />
1.12 t/ha of productivity. This area is unique <strong>in</strong> that rice is direct seeded over 90 per cent of the<br />
area. The crop is direct seeded under relatively dry c<strong>on</strong>diti<strong>on</strong>s and the fields rema<strong>in</strong> unflooded<br />
for most part of the period. The regi<strong>on</strong> receives an annual ra<strong>in</strong>fall of 619 to 1303 mm. The soils<br />
vary from laterite to clay loams. Mixed red and black soils also prevail. These soils exhibit<br />
moderate fertility. <strong>Rice</strong> is grown <strong>in</strong> terraced fields with three types of land situati<strong>on</strong>s – up lands,<br />
mid lands and low lands. Short durati<strong>on</strong> rice varieties grown <strong>in</strong> up lands and mid-late varieties <strong>in</strong><br />
mid-lands. Late durati<strong>on</strong> (l<strong>on</strong>g durati<strong>on</strong>) varieties are grown <strong>in</strong> lowlands. On a limited area, rice<br />
is also grown dur<strong>in</strong>g summer seas<strong>on</strong> (January-February to March-April) us<strong>in</strong>g lift irrigati<strong>on</strong>.<br />
4. Tankfed area: The area under rice <strong>in</strong> tank-fed area is around 0.15 m ha with the<br />
productivity of 2.48 t/ha. This regi<strong>on</strong> <strong>in</strong>cludes the districts of Kolar, Bangalore, Tumkur and parts<br />

of Hassan. It covers 11.0 per cent of the area under rice. This area receives an average annual<br />
ra<strong>in</strong>fall of about 760 mm. Tanks get filled dur<strong>in</strong>g October-November. The irrigati<strong>on</strong> is through<br />
tanks water <strong>on</strong>ly. Generally two crops are grown. This regi<strong>on</strong> is unique that rice is grown <strong>on</strong><br />
semi-dry cum wet crop called Punaji. <strong>Rice</strong> is sown dry dur<strong>in</strong>g June-July and carried <strong>on</strong> as a dry<br />
crop until August-September. Water is impounded late <strong>in</strong> September-October and later<br />
cultivated as wet rice. In additi<strong>on</strong> transplant<strong>in</strong>g is also <strong>in</strong> practice but late <strong>in</strong> the seas<strong>on</strong> <strong>in</strong><br />
August-September. This class of rice is harvested <strong>in</strong> December-January. Summer rice is grown<br />
<strong>on</strong> a limited area <strong>on</strong>ly when tank water is available.<br />
5. Irrigated maidan area (South): It occupies an area of 0.18 m ha, with the productivity of<br />
2.59 t/ha. This <strong>in</strong>cludes the canal irrigated areas of Mandya, Mysore, Hassan, Chamarajanagar<br />
and parts of Shimoga, Davanagere and Chitradurga districts. This area receives an annual<br />
ra<strong>in</strong>fall of 778 mm. The soils are mostly red <strong>in</strong> colour, sandy to loamy <strong>in</strong> texture and rich <strong>in</strong><br />
potash. It has two ma<strong>in</strong> seas<strong>on</strong> viz., the kharif (June-July to November-December) and summer<br />
(January-February to May-June). In kharif seas<strong>on</strong> varieties of l<strong>on</strong>g durati<strong>on</strong> (140-145 days),<br />
medium durati<strong>on</strong> (130-135 days) and short durati<strong>on</strong> (110-115 days) are grown while dur<strong>in</strong>g<br />
summer it varies from short durati<strong>on</strong> to l<strong>on</strong>g durati<strong>on</strong> depend<strong>in</strong>g up<strong>on</strong> the availability of water<br />
<strong>in</strong> the reservoir / tank. In this area low temperature prevails dur<strong>in</strong>g November – January.<br />
6. Irrigated maidan area (North): This occupies an area of 0.21 m ha with the productivity of<br />
2.53 t/ha. It comprises Raichur, Bellary, Haveri, Koppal, Dharwad, Gulbarga and Belgaum<br />
districts. Major source of irrigati<strong>on</strong> <strong>in</strong> Raichur, Bellary, Haveri and Koppal districts is<br />
Tungabhadra Project. This regi<strong>on</strong> receives an annual ra<strong>in</strong>fall of 600 mm <strong>on</strong>ly. The rice soils vary<br />
from black cott<strong>on</strong> type to mostly lighter black to reddish <strong>in</strong> colour. These soils exhibit a fair<br />
degree of fertility and are generally rich <strong>in</strong> lime and magnesium. C<strong>on</strong>siderable areas are affected<br />
by sal<strong>in</strong>ity and/or alkal<strong>in</strong>ity. As <strong>in</strong> southern irrigated maidan area here also two crops are grown.<br />
In the kharif seas<strong>on</strong> rice varieties of 140-145 days durati<strong>on</strong> are cultivated while summer crop is<br />
cultivated <strong>on</strong> limited areas with short to mid-early durati<strong>on</strong> genotypes.<br />

VIII. <strong>Rice</strong> grow<strong>in</strong>g seas<strong>on</strong>s and regi<strong>on</strong>s<br />
Major rice grow<strong>in</strong>g areas of the state can be broadly classified <strong>in</strong>to two seas<strong>on</strong>s, viz.,<br />
kharif (June-July) and summer (January-February). In all the six rice grow<strong>in</strong>g ecosystems, Kharif<br />
sow<strong>in</strong>g is comm<strong>on</strong> while dur<strong>in</strong>g summer seas<strong>on</strong> the crop is cultivated ma<strong>in</strong>ly <strong>in</strong> the irrigated<br />
maidan areas of north and south. In the tank-fed areas, the crop is taken up late <strong>in</strong> the seas<strong>on</strong><br />
(August-September) depend<strong>in</strong>g up<strong>on</strong> the m<strong>on</strong>so<strong>on</strong> showers. In coastal area, <strong>on</strong>e can see a<br />
specific situati<strong>on</strong> where a sec<strong>on</strong>d crop is sown <strong>in</strong> September-October and harvested <strong>in</strong> January-<br />
February and the third crop is cultivated between December-January and March-April. In each<br />
district, nearly 60-80 per cent of the total area is covered dur<strong>in</strong>g Kharif (wet) seas<strong>on</strong> while the<br />
rema<strong>in</strong><strong>in</strong>g area is occupied <strong>in</strong> late Kharif and summer (dry) seas<strong>on</strong>.<br />

X (a). Traditi<strong>on</strong>al <strong>Rice</strong> Varieties:<br />
Traditi<strong>on</strong>al rice varieties is be<strong>in</strong>g grown <strong>in</strong> very few selected regi<strong>on</strong>s of the state. The<br />
major area of these varieties can be seen <strong>in</strong> Malnad, Hilly and Coastal tracts <strong>in</strong> Shimoga, Hassan,<br />
Coorg, Udupi and South Kanara districts. Most popular traditi<strong>on</strong>al <strong>Rice</strong> varieties cultivated <strong>in</strong><br />
these areas <strong>in</strong>clude Rajaboga, Rajamudi, Kayame, Ratnachudi and Jerasanna. In maidan areas of<br />
southern <strong>Karnataka</strong> cultivati<strong>on</strong> of Haluballu can be seen <strong>in</strong> a limited area.<br />
Rajaboga, Rajamudi and Ratnachudi are l<strong>on</strong>g durati<strong>on</strong>, photosensitive, tall varieties with<br />
f<strong>in</strong>e gra<strong>in</strong> quality. These varieties suite very well for the cropp<strong>in</strong>g system of malnad tract.<br />
Hence, these are cultivated <strong>in</strong> few selected areas of the regi<strong>on</strong>. Jerasanna is cultivated <strong>in</strong> hilly<br />
tracts of South Coorg and part of Hassan districts ow<strong>in</strong>g to its f<strong>in</strong>eness and scented nature. The<br />
cultivati<strong>on</strong> of ‘Haluballu’ a medium durati<strong>on</strong>, variety can be attributed to its good taste and<br />
tolerance to pests and diseases.<br />
Cultivati<strong>on</strong> of rice <strong>in</strong> <strong>Karnataka</strong> state (earlier called as Mysore state) it as old as its<br />
cultivati<strong>on</strong> <strong>in</strong> the country. There were many varieties grown <strong>in</strong> different parts of the state under<br />
varied agro-ecological situati<strong>on</strong>s. An exhaustive list of traditi<strong>on</strong>al rice varieties of erstwhile<br />
Mysore state is compiled by Ramaiah (1953) and Richharia and Gov<strong>in</strong>daswamy (1966). The most<br />
important traditi<strong>on</strong>al rice varieties of the state and their salient features are given <strong>in</strong> Table14<br />

X (b). Traditi<strong>on</strong>al classificati<strong>on</strong> of rice lands and cropp<strong>in</strong>g seas<strong>on</strong>s <strong>in</strong> the state<br />
The cultivati<strong>on</strong> of rice <strong>in</strong> the state dates back to early part of 20 th century. Dur<strong>in</strong>g this<br />
period, it was cultivated <strong>in</strong> an area of 3.2 lakh ha with a producti<strong>on</strong> of 0.21 milli<strong>on</strong> t<strong>on</strong>nes. The<br />
practice of rice cultivati<strong>on</strong> purely under m<strong>on</strong>so<strong>on</strong>, m<strong>on</strong>so<strong>on</strong> followed by tank water and through<br />
artificial irrigati<strong>on</strong> by canal water under different agro-ecological situati<strong>on</strong> was documented by<br />
Ramiah and Rao (1953). Coastal regi<strong>on</strong> adjo<strong>in</strong><strong>in</strong>g to Arabian sea <strong>in</strong> western part of the state has<br />
been a traditi<strong>on</strong>al rice grow<strong>in</strong>g area. <strong>Rice</strong> was be<strong>in</strong>g cultivat<strong>in</strong>g here almost throughout the year<br />
<strong>in</strong> different topographical situati<strong>on</strong>s. The farmers used to grow the crop under five different<br />
periods / seas<strong>on</strong>s and locally designated them as Anilu, Patla, Suggi, Yedekolake and Kolke.<br />
These seas<strong>on</strong>s can be simulated with the present kharif (May-June), late kharif (July-August),<br />
rabi (September-October), early summer (December-January) and summer (January-February).<br />
The cultivati<strong>on</strong> was practiced <strong>on</strong> different land system and locally/traditi<strong>on</strong>ally called as Bettu<br />
(upland), Majalu (mid land), Bailu (low land) and Patla (river bank). It was grown purely as a<br />
purely ra<strong>in</strong>fed crop <strong>in</strong> the hilly areas of malnad tract where soils are generally poor. Broadcast<strong>in</strong>g<br />
of seeds was the usual practice <strong>in</strong> these areas. In maidan (flat) bas<strong>in</strong>s the crop was grown us<strong>in</strong>g<br />
m<strong>on</strong>so<strong>on</strong>s with a protective irrigati<strong>on</strong> from tanks. The cropp<strong>in</strong>g periods <strong>in</strong> the above two<br />
situati<strong>on</strong>s prevailed between June to September. The crop was also cultivated purely under<br />
canal irrigati<strong>on</strong> <strong>in</strong> maidan areas dur<strong>in</strong>g the said seas<strong>on</strong>. In lowland with tank water facility,<br />
cultivati<strong>on</strong> was also under practiced dur<strong>in</strong>g summer m<strong>on</strong>ths (January to April) popularly called as<br />
Kar seas<strong>on</strong>.<br />
X (c). Traditi<strong>on</strong>al cultural practices for pest and disease management<br />
Cultivati<strong>on</strong> practices followed <strong>in</strong> rice prior to the <strong>in</strong>troducti<strong>on</strong> of improved varieties,<br />
chemical fertilizers, plant protecti<strong>on</strong> chemicals and mach<strong>in</strong>eries / agricultural equipments etc.<br />
was not systematic and uniform <strong>in</strong> the state. Farmers used to follow different methods as per<br />
their c<strong>on</strong>venience and suitability <strong>in</strong> different traditi<strong>on</strong>al rice grow<strong>in</strong>g areas.<br />

RICE IN KARNATAKA<br />
Hilly areas, coastal areas and transiti<strong>on</strong>al areas of the state are c<strong>on</strong>sidered as traditi<strong>on</strong>al<br />
rice areas of state. In hilly and coastal areas, cultivati<strong>on</strong> of rice was d<strong>on</strong>e <strong>on</strong> different soil<br />
topography. The popular <strong>on</strong>es are Bettu (upland), Majalu (mid land), Bailu (low land) and Patla<br />
(river bank). In all these eco-systems broadcast<strong>in</strong>g of unsprouted seeds was the comm<strong>on</strong><br />
practice. Manual weed<strong>in</strong>g and plant protecti<strong>on</strong>s were not comm<strong>on</strong>. Applicati<strong>on</strong> of forest soils<br />
was the usual practice <strong>in</strong> many places. Harvest<strong>in</strong>g and process<strong>in</strong>g of the produce was d<strong>on</strong>e at<br />
family level as the land hold<strong>in</strong>gs were small and scattered.<br />
In transiti<strong>on</strong>al areas, farmers broadcast the self saved seeds after plough<strong>in</strong>g their land and<br />
cover it up by pass<strong>in</strong>g a wooden plank <strong>on</strong> the land. In some other areas, sow<strong>in</strong>g was also<br />
practiced <strong>in</strong> the plough soles al<strong>on</strong>g with decomposed (FYM) farm yard manure. Weed<strong>in</strong>g was<br />
not usually practiced <strong>in</strong> the broadcasted crop while <strong>in</strong> l<strong>in</strong>e sow<strong>in</strong>g it was c<strong>on</strong>trolled by <strong>in</strong>tercultivati<strong>on</strong><br />
by bullocks. No c<strong>on</strong>trol measures were practiced for pest and disease <strong>in</strong> the ra<strong>in</strong>-fed<br />
ecosystem. However, pulses and oilseeds were <strong>in</strong>termixed (<strong>in</strong>tercropped) which c<strong>on</strong>trol the<br />
pests and diseases to certa<strong>in</strong> extent.<br />
In all these areas, rice was cultivated ma<strong>in</strong>ly dur<strong>in</strong>g m<strong>on</strong>so<strong>on</strong> period (May to August). In<br />
coastal and hilly areas where water was available <strong>in</strong> the valleys and streams, rice was cultivated<br />
to a limited extent dur<strong>in</strong>g summer seas<strong>on</strong>. In transiti<strong>on</strong>al area, farmers grow crop us<strong>in</strong>g tank<br />
water wherever available.<br />

a. SRI<br />
Need for SRI:<br />
The rice producti<strong>on</strong> <strong>in</strong> India is str<strong>on</strong>gly <strong>in</strong>fluenced by the amount and distributi<strong>on</strong> of<br />
ra<strong>in</strong>fall. The water crisis that we are fac<strong>in</strong>g to-day is the greatest threat to rice cultivati<strong>on</strong>.<br />
Inadequate ra<strong>in</strong>fall, lack of water harvest<strong>in</strong>g measures and unscientific way use of water for<br />
agriculture have brought down the per-capita availability of water by 40-60% <strong>in</strong> many Asian<br />
countries <strong>in</strong>clud<strong>in</strong>g India. The depleti<strong>on</strong> of ground water, <strong>in</strong>adequate water <strong>in</strong> reservoirs has<br />
forced many farmers to aband<strong>on</strong>ed rice cultivati<strong>on</strong>. S<strong>in</strong>ce rice is most water c<strong>on</strong>sum<strong>in</strong>g crop,<br />
alternative rice cultivati<strong>on</strong> strategies that require less water needs an hour. To mitigate the<br />
loom<strong>in</strong>g water crisis there is a need to develop novel technologies and producti<strong>on</strong> system that<br />

productivity of irrigated rice by chang<strong>in</strong>g the management of plant, soil, water and nutrients.<br />
More changes <strong>in</strong> this system are lower seed rate (5 kg/ha) , plant<strong>in</strong>g of young seedl<strong>in</strong>gs of 10-12<br />
days at wider spac<strong>in</strong>g of 25 cm x 25 cm or 30 cm x 30 cm with good soil c<strong>on</strong>diti<strong>on</strong>s, use of more<br />
organic nutrients sources, regular weed<strong>in</strong>g and us<strong>in</strong>g less water (no flood<strong>in</strong>g) to achieve higher<br />
yield. SRI has been purposefully called a system rather than a technology as it <strong>in</strong>volves the<br />
holistic management to give ideal grow<strong>in</strong>g c<strong>on</strong>diti<strong>on</strong> to rice plant.<br />
Impact of SRI :<br />
In southern <strong>Karnataka</strong>, adopti<strong>on</strong> of system of rice <strong>in</strong>tensificati<strong>on</strong> is very meager and this<br />
system of rice grow<strong>in</strong>g has hardy created impact. Even though the SAUs, KSDA and NGOs of the<br />
state have c<strong>on</strong>ducted dem<strong>on</strong>strati<strong>on</strong> <strong>on</strong> SRI, but the farmers of this regi<strong>on</strong> are reluctant to<br />
adopt the technology because of more physical drudgery <strong>in</strong>volved <strong>in</strong> transplant the young<br />
seedl<strong>in</strong>gs <strong>in</strong> square plant<strong>in</strong>g, frequent weed<strong>in</strong>g, problems <strong>in</strong> adopt<strong>in</strong>g <strong>in</strong>termittent irrigati<strong>on</strong>,<br />
n<strong>on</strong>-availability of critical implements like marker and weeder and f<strong>in</strong>ally farmers m<strong>in</strong>d set itself<br />
is the major obstacle <strong>in</strong> the way of adopti<strong>on</strong> of this novel management practice for enhanc<strong>in</strong>g<br />
irrigated rice producti<strong>on</strong>. Hence, there is a need of ref<strong>in</strong>ement of SRI practice to suit the farmers<br />
need and local c<strong>on</strong>diti<strong>on</strong>s.<br />
b. Hybrid rice<br />
The basic research <strong>on</strong> hybrid rice <strong>in</strong> <strong>Karnataka</strong> started dur<strong>in</strong>g 1970s under the guidance<br />
of Dr. M.Mahadevappa. It was <strong>in</strong>tensified through post graduate research when he returned<br />
from Ch<strong>in</strong>a with technical know-how and breed<strong>in</strong>g materials <strong>in</strong> 1981. In 1989 it was further<br />
strengthened under the leadership of Dr. B.Vidyachandra when government of India sancti<strong>on</strong>ed<br />
ICAR/UNDP aided project <strong>on</strong> hybrid rice to Mandya recogniz<strong>in</strong>g it as <strong>on</strong>e of the lead centers for<br />
hybrid rice research <strong>in</strong> India. The <strong>in</strong>tensive and systematic work d<strong>on</strong>e by the project has resulted<br />
<strong>in</strong> the release of two hybrids viz., <strong>Karnataka</strong> <strong>Rice</strong> Hybrid 1 (KRH 1) <strong>in</strong> 1994 and <strong>Karnataka</strong> <strong>Rice</strong><br />
Hybrid 2 (KRH 2) <strong>in</strong> 1996. KRH 1 is a short durati<strong>on</strong> hybrid matur<strong>in</strong>g <strong>in</strong> about 120 –125 days with<br />
the yield potential of around 6 t/ha. KRH 2 <strong>on</strong> the other hand is a medium durati<strong>on</strong> hybrid<br />
matur<strong>in</strong>g <strong>in</strong> about 130-135 days with the yield potential of around 10 t/ha. The gra<strong>in</strong> is l<strong>on</strong>g<br />

slender with little aroma. On an average it yields <strong>on</strong>e t<strong>on</strong>es extra per hectare over the best check<br />
variety that is Jaya with the durati<strong>on</strong> advantage of about 15 –20 days. In 2002 it has been<br />
accepted for release at nati<strong>on</strong>al level for all rice grow<strong>in</strong>g areas <strong>in</strong> the country except for coastal<br />
and hilly regi<strong>on</strong>s. It is accepted for yield widely across the country.<br />
Future strategies<br />
The future research strategies for populariz<strong>in</strong>g rice hybrids <strong>in</strong> <strong>Karnataka</strong> should focus <strong>on</strong><br />
the follow<strong>in</strong>g aspects.<br />
• Development of medium durati<strong>on</strong>, bold gra<strong>in</strong> hybrids without scent.<br />
• Development of medium durati<strong>on</strong>, l<strong>on</strong>g slender hybrids without scent.<br />
• Development of medium durati<strong>on</strong>, medium slender hybrids without scent<br />
• Development of medium durati<strong>on</strong>, l<strong>on</strong>g bold red rice hybrids without scent<br />
• Development of hybrids suitable for delayed sow<strong>in</strong>gs (July-August) and for adverse<br />
soils with tolerance to cold, blast and BPH.<br />
• Development of hybrids suitable for coastal and hilly areas with tolerance to blast<br />
and gall midge.<br />
Development of suitable parental l<strong>in</strong>es to achieve the above objectives and appropriate<br />
seed producti<strong>on</strong> practices need immediate attenti<strong>on</strong> of the researchers.<br />
c. Aerobic rice / c<strong>on</strong>servati<strong>on</strong> agriculture :<br />
<strong>Rice</strong> is an important food crop largely cultivated under submerged c<strong>on</strong>diti<strong>on</strong> by<br />
transplant<strong>in</strong>g. This method of cultivati<strong>on</strong> requires large quantities of water and is labour<br />
<strong>in</strong>tensive. It is estimated that 5000 liters of water is needed to produce 1 kg of rice. Water is<br />
most limited natural resource of late, due to failure of ra<strong>in</strong>s and over exploitati<strong>on</strong> of ground<br />
water. The dw<strong>in</strong>dl<strong>in</strong>g water resources reveal a grim situati<strong>on</strong> for lowland puddled rice<br />
cultivati<strong>on</strong>. Farmers are seek<strong>in</strong>g alternate methods of cultivati<strong>on</strong> for grow<strong>in</strong>g <strong>Rice</strong> to combat<br />
this water scarce situati<strong>on</strong>. One such method is cultivati<strong>on</strong> of rice under aerobic situati<strong>on</strong> which<br />
is, characterized by aerated soil envir<strong>on</strong>ment dur<strong>in</strong>g the entire period of crop growth. In this<br />

type of cultivati<strong>on</strong> rice is grown like ragi, maize of Jowar by giv<strong>in</strong>g surface irrigati<strong>on</strong>. Irrigati<strong>on</strong> is<br />
provided <strong>on</strong>ce <strong>in</strong> 5-7 days <strong>in</strong> a direct seeded aerobic rice crop. Varieties suitable for this type of<br />
cultivati<strong>on</strong> also possess ability to withstand drought periods. Varieties are bred for aerobic<br />
situati<strong>on</strong> with root <strong>in</strong>trogressed from upland genotype base that yield <strong>on</strong> an average of 5.0 t/ha<br />
of gra<strong>in</strong> and 6.00 t/ha of fodder. This type of cultivati<strong>on</strong> saves about 60 percent of water. The<br />
amount of methane emitted under aerobic situati<strong>on</strong> is very low thus protect<strong>in</strong>g the<br />
envir<strong>on</strong>ment. A new mid-early, high yield<strong>in</strong>g variety MAS 946-1 is recently released by the<br />
University for Aerobic Cultivati<strong>on</strong>.<br />
Advantages of Aerobic Cultivati<strong>on</strong>:<br />
• Puddl<strong>in</strong>g and submergence is not required<br />
• Direct seed sow<strong>in</strong>g<br />
• Nursery and transplant<strong>in</strong>g not required<br />
• Less quantity of seed requirement<br />
• Less labour requirement<br />
• Sav<strong>in</strong>g irrigati<strong>on</strong> water upto 60 per cent<br />
• Efficient fertilizer utilizati<strong>on</strong><br />
• Low pest / diseases <strong>in</strong>cidence<br />
• Reduced methane emissi<strong>on</strong> lead<strong>in</strong>g to lower envir<strong>on</strong>mental polluti<strong>on</strong><br />
• Profuse root<strong>in</strong>g and high tiller<strong>in</strong>g, less lodg<strong>in</strong>g and high gra<strong>in</strong> and fodder yield<br />
• Retenti<strong>on</strong> of soil structure and quality<br />
• C<strong>on</strong>trol of mosquitoes<br />

areas. Plough<strong>in</strong>g immediately after harvest (fall plough<strong>in</strong>g) can destroy the stages of the pest.<br />
Bunds scrap<strong>in</strong>g dur<strong>in</strong>g January / February can m<strong>in</strong>imize the grasshopper <strong>in</strong>cidence. Some other<br />
important cultural practices which reduce the <strong>in</strong>cidence of <strong>in</strong>sect pests are proper bund<br />

Integrated Diseases Management (IDM):<br />
<strong>Rice</strong> crop is encountered by fungi, bacteria, viruses, nematodes and mycoplasmas. After<br />
the <strong>in</strong>troducti<strong>on</strong> of dwarfs HYV the disease spectrum was widened due to narrow genetic make<br />
up. Intensive crop management <strong>in</strong>clud<strong>in</strong>g heavy chemical fertilizati<strong>on</strong>, c<strong>on</strong>t<strong>in</strong>uous flood<strong>in</strong>g<br />
aggravates the disease problem further c<strong>on</strong>t<strong>in</strong>uous m<strong>on</strong>oculture of rice helps <strong>in</strong> perpetuati<strong>on</strong> of<br />
pathogens from crop to crop. Presence of collateral hosts, <strong>in</strong>fected seed and plant debries n<strong>on</strong><br />
adopti<strong>on</strong> of clean cultivati<strong>on</strong> are also important factors for the spread of diseases. Close<br />
plant<strong>in</strong>g coupled with high N dress<strong>in</strong>g enhance the humidity of microclimate and create<br />
c<strong>on</strong>ducive envir<strong>on</strong>ment for the disease spread. The loss <strong>in</strong> yield due to diseases may vary from<br />
10 to 30% depend<strong>in</strong>g <strong>on</strong> seas<strong>on</strong>, weather c<strong>on</strong>diti<strong>on</strong>s and variety cultivati<strong>on</strong>.<br />
The important diseases of rice observed <strong>in</strong> Southern Dry Z<strong>on</strong>e of <strong>Karnataka</strong> are blast,<br />
brown leaf spot, bacterial blight, sheath blight, sheath rot, Uddabatta, root knot nematode, false<br />
smut and tungro diseases (Anjaneyulu 1986 and EPPO 2005) which are caus<strong>in</strong>g ec<strong>on</strong>omic loss to<br />

RICE IN KARNATAKA<br />
Of late rice farmers used chemicals al<strong>on</strong>e for the c<strong>on</strong>trol of these diseases which led to<br />
deteriorati<strong>on</strong> of soil health, besides pollut<strong>in</strong>g water and envir<strong>on</strong>ment. Keep<strong>in</strong>g all this <strong>in</strong> view<br />
IPM approach has came <strong>in</strong>to existence which refers to harm<strong>on</strong>ious use of multiple methods to<br />
c<strong>on</strong>trol s<strong>in</strong>gle disease as well as multiple diseases that are practical effective ec<strong>on</strong>omical and<br />
protective of both public health and envir<strong>on</strong>ment.<br />
The IDM approaches <strong>in</strong>cluded for the c<strong>on</strong>trol of rice diseases are grow<strong>in</strong>g of resistant<br />
varieties, cultural practices biological and chemical methods.<br />
A. C<strong>on</strong>troll<strong>in</strong>g fungus diseases<br />
i) Resistant varieties :<br />
Plant<strong>in</strong>g resistant varieties is the least expense and safest method of disease c<strong>on</strong>trol.<br />
<strong>Rice</strong> varieties like BR-2655, KMP 105, Rasi, Mangala, IET 1791, are some of the blast resistant<br />
l<strong>in</strong>es be<strong>in</strong>g recommended <strong>in</strong> Southern dry z<strong>on</strong>e of <strong>Karnataka</strong>. Whereas, IET 1791 and Amruth<br />
varieties found resistant to brown spot disease. Varietal mixtures can also be used to reduce<br />
slow disease spread.<br />
ii) Regulatory and cultural c<strong>on</strong>trols :<br />
Quarant<strong>in</strong>e is particularly important because most fungus disease of rice are seed borne.<br />
Almost all cultural practices used <strong>in</strong> rice producti<strong>on</strong> are tim<strong>in</strong>g of plant<strong>in</strong>g and harvest<strong>in</strong>g,<br />
fertilizer applicati<strong>on</strong>, tillage, weed c<strong>on</strong>trol and cropp<strong>in</strong>g system affect disease development.<br />
Judicious use of nitrogen fertilizers helps <strong>in</strong> reduc<strong>in</strong>g blast, sheath blight and brown spot<br />
diseases. Changes <strong>in</strong> cropp<strong>in</strong>g pattern crop rotati<strong>on</strong> are important to break c<strong>on</strong>t<strong>in</strong>uity <strong>in</strong> disease<br />
cycle and reducti<strong>on</strong> <strong>in</strong> disease severity <strong>in</strong> endemic areas.<br />
iii) Biological c<strong>on</strong>trol :<br />
Bio-c<strong>on</strong>trol agents such as Trichoderma viridae and Pseudom<strong>on</strong>as fluroscence are known<br />
to cause deleterious effects <strong>on</strong> Rhizoct<strong>on</strong>ia solani caus<strong>in</strong>g sheath blight <strong>in</strong> rice. In endemic areas<br />
<strong>in</strong>corporati<strong>on</strong> of these bio c<strong>on</strong>trol agents to soil al<strong>on</strong>g with organic matter (FYM, pressmud and<br />
wormicompost etc.) can be d<strong>on</strong>e for the susta<strong>in</strong>able management of this disease.<br />

RICE IN KARNATAKA<br />
iv) Chemical c<strong>on</strong>trol :<br />
Seed treatment with Carbendazim @ 2 g/kg seed is the most effective method for blast<br />
c<strong>on</strong>trol for 30-40 d after sow<strong>in</strong>g. Spray<strong>in</strong>g of carbendazim @ 1 g or Ediphenphos @ 1 ml or<br />
Tricyclazole @ 0.6 g or Kitaz<strong>in</strong> @ 1 ml <strong>in</strong> <strong>on</strong>e lit of water are be<strong>in</strong>g recommended for c<strong>on</strong>trol of<br />
blast <strong>in</strong> the field crop.<br />
For brown spot management foliar applicati<strong>on</strong> of Ediphenphos @ 1 ml or Mancozeb @ 2 g<br />
per lit of water are be<strong>in</strong>g recommended.<br />
Hot water treatment of seeds at 52 0 C for 10 m<strong>in</strong>utes, is highly effective <strong>in</strong> elim<strong>in</strong>ati<strong>on</strong> of<br />
uddabatta disease.<br />
Foliar applicati<strong>on</strong> of Carbendazim @ 1 g or Tilt @ 1 ml/lit of water is recommended for<br />
the management of sheath blight disease.<br />
B. C<strong>on</strong>troll<strong>in</strong>g of bacterial diseases :<br />
The effectiveness of chemical c<strong>on</strong>trols are limited by heavy ra<strong>in</strong>s, therefore varietal<br />
resistance is the most important way to c<strong>on</strong>trol bacterial leaf blight. Use of resistant varieties<br />
like IR-20, IR-50 and IR-64 etc. is most ec<strong>on</strong>omical.<br />
Cultural methods such as avoid<strong>in</strong>g chopp<strong>in</strong>g of leaves, avoid<strong>in</strong>g top dress<strong>in</strong>g at tiller<strong>in</strong>g<br />
stage is be<strong>in</strong>g recommended.<br />
Seed treatment with 0.1 g. Streptocycl<strong>in</strong>e 0.1 g. copper sulphate <strong>in</strong> <strong>on</strong>e litre of water for<br />
30 m<strong>in</strong>utes. Foliar applicati<strong>on</strong> of 0.05 g. streptocycl<strong>in</strong>e and 0.05 g. of copper sulphate <strong>in</strong> <strong>on</strong>e<br />
litre of water is also recommended for the c<strong>on</strong>trol of bacterial leaf blight. C. C<strong>on</strong>troll<strong>in</strong>g virus<br />
diseases :<br />
Elim<strong>in</strong>at<strong>in</strong>g vector <strong>in</strong>sects is the best way to c<strong>on</strong>trol virus diseases out breaks. Soil<br />
applicati<strong>on</strong> of Carbofur<strong>on</strong> @ 33 kg/ha is be<strong>in</strong>g recommended.<br />
Foliar applicati<strong>on</strong> of m<strong>on</strong>ocrotophos @ 1.5 ml/lit of water is recommended and it is<br />
found most effective.<br />

D. C<strong>on</strong>troll<strong>in</strong>g Nematode diseases :<br />
Treat<strong>in</strong>g the seeds with hot water (52-53 0 C) for 15 m<strong>in</strong>utes reduce nematode <strong>in</strong>fecti<strong>on</strong>.<br />
Soil applicati<strong>on</strong> or Carbofur<strong>on</strong> @ 33 kg/ha or soil solarizati<strong>on</strong> for 4 weeks <strong>in</strong> hot summer or soil<br />
<strong>in</strong>corporati<strong>on</strong> of Neem cake @ 250 kg/ha is found effective for the root knot nematode <strong>in</strong> rice.<br />
Grow<strong>in</strong>g of green manur<strong>in</strong>g crops such as Sunnhemp/Diancha/Cowpea can also elim<strong>in</strong>ate<br />
root knot nematodes.<br />
Much efforts are to be put <strong>in</strong> to encourage the farm<strong>in</strong>g community to adopt the IDM<br />
approaches. This is not <strong>on</strong>ly helps to susta<strong>in</strong> higher productivity <strong>in</strong> rice but also helps <strong>in</strong> reduc<strong>in</strong>g<br />
the fungicide/pesticide usage.<br />
E. Integrated Nutrient Management :<br />
Intensive rice cropp<strong>in</strong>g with short-durati<strong>on</strong> high-yield<strong>in</strong>g varieties al<strong>on</strong>g with <strong>in</strong>creased<br />
use of m<strong>in</strong>eral fertilizers and improved irrigati<strong>on</strong> facilities have resulted <strong>in</strong> spectacular <strong>in</strong>creases<br />
<strong>in</strong> crop productivity. This has, however, led to gradual replacement of organic manures as<br />

is relatively small. N<strong>on</strong>etheless, <strong>in</strong>tegrated use of organic and m<strong>in</strong>eral fertilizers has been found<br />
to be more effective <strong>in</strong> ma<strong>in</strong>ta<strong>in</strong><strong>in</strong>g higher productivity and stability through correcti<strong>on</strong> of<br />
deficiencies of sec<strong>on</strong>dary and micr<strong>on</strong>utrients <strong>in</strong> the course of m<strong>in</strong>eralizati<strong>on</strong> <strong>on</strong> <strong>on</strong>e hand and<br />
favorable physical and soil ecological c<strong>on</strong>diti<strong>on</strong>s <strong>on</strong> the other. Organic manur<strong>in</strong>g also improves<br />
the physical and microbial c<strong>on</strong>diti<strong>on</strong>s of soil and enhances fertilizer use efficiency when applied<br />
<strong>in</strong> c<strong>on</strong>juncti<strong>on</strong> with m<strong>in</strong>eral fertilizers. Thus, all the major sources of plant nutrients such as soil,<br />
m<strong>in</strong>eral, organic and biological should be utilized <strong>in</strong> an efficient and judicious manner for<br />
susta<strong>in</strong>able crop producti<strong>on</strong> <strong>in</strong> rice-rice cropp<strong>in</strong>g system.<br />
Several studies have been c<strong>on</strong>ducted <strong>on</strong> the complementary use of organic and m<strong>in</strong>eral<br />
fertilisers <strong>in</strong> cropp<strong>in</strong>g systems <strong>in</strong>volv<strong>in</strong>g rice. Extensive field <strong>in</strong>vestigati<strong>on</strong>s <strong>in</strong> the acid lateritic<br />
soils at Kharagpur revealed that locally available organic materials such as chopped straw, FYM,<br />
water hyac<strong>in</strong>th compost, Azolla and green manure <strong>in</strong> situ with sunnhemp and Dha<strong>in</strong>cha can<br />
substitute N fertilizer up to 50 per cent of the total crop requirement. In a study <strong>on</strong> <strong>Rice</strong> based<br />
cropp<strong>in</strong>g system, it was found that significant <strong>in</strong>crease <strong>in</strong> yield parameter as well as soil nutrient<br />
status <strong>in</strong> INH treatment i.e 50% NPK + 25% N through green manure + % N through FCM. Also<br />
found that yield levels were stabilized dur<strong>in</strong>g 1999-2009 <strong>in</strong> the INH treatments <strong>in</strong> Red sandy<br />
loam soils of ZARS, V.C.Farm, Mandya. It was however more beneficial to apply the organic<br />
manure <strong>in</strong> the Kharif seas<strong>on</strong> because of its better decompositi<strong>on</strong> and m<strong>in</strong>eralizati<strong>on</strong> of nutrients<br />
<strong>in</strong> soil. Further, the effect of FYM applicati<strong>on</strong> was found to be comparable or even superior to<br />
lime amendment <strong>on</strong> the acidic soils which seemed ma<strong>in</strong>ly due to the formati<strong>on</strong> of A1-organochellates,<br />
result<strong>in</strong>g <strong>in</strong> the reducti<strong>on</strong> of A1 c<strong>on</strong>centrati<strong>on</strong> <strong>in</strong> soil soluti<strong>on</strong> to levels beneficial to<br />
plant growth. Similarly, <strong>in</strong> the red soils of Hyderabad, the average <strong>in</strong>crease <strong>in</strong> rice yield due to<br />
NPK+FYM was 17-21 percent <strong>in</strong> both Kharif and Rabi seas<strong>on</strong>s. These and other results suggest<br />
that substituti<strong>on</strong> of 25-50 percent of the N through FYM <strong>in</strong> Kharif and applicati<strong>on</strong> of 75-100<br />
percent optimum level of NPK <strong>in</strong> the Rabi produced the highest yields of rice. The beneficial<br />
effect of organic manures <strong>in</strong> <strong>in</strong>creas<strong>in</strong>g nitrogen-use-efficiency was also evident, particularly <strong>in</strong><br />
the Rabi seas<strong>on</strong>. Further applicati<strong>on</strong> of NPK fertilizers al<strong>on</strong>e did not <strong>in</strong>fluence the yield of<br />
succeed<strong>in</strong>g rice crop but the residual effect was observed with the <strong>in</strong>corporati<strong>on</strong> of organic<br />
manure. The gra<strong>in</strong> yield of Kharif rice was <strong>in</strong>creased by 21-22 percent and 10-13 percent with<br />

the applicati<strong>on</strong> of Azolla or wheat straw and FYM or water hyac<strong>in</strong>th compost, respectively. The<br />
residual effect of these sources <strong>on</strong> the succeed<strong>in</strong>g Rabi rice showed a yield <strong>in</strong>crease of 14-18<br />
percent and 8-10 percent compared with the c<strong>on</strong>trol. Further, the residual effect was more<br />
pr<strong>on</strong>ounced with <strong>in</strong>tegrated used of NPK fertilisers and organic manures. Therefore, <strong>in</strong>tegrated<br />
nutrient supply is important as a soil ameliorant <strong>in</strong> alleviat<strong>in</strong>g the adverse soil ecological<br />
c<strong>on</strong>diti<strong>on</strong>s as <strong>in</strong> the case of acid lateritic soils and <strong>in</strong> improv<strong>in</strong>g soil fertility and productivity.<br />
Green manure of legume shrubs or tree lopp<strong>in</strong>gs has been known to be beneficial for<br />
susta<strong>in</strong><strong>in</strong>g rice productivity. Sunnhemp and Dha<strong>in</strong>cha are popular legumes for green manur<strong>in</strong>g<br />
<strong>in</strong> rice and can accumulate up to 100 kg N/ha <strong>in</strong> 50-55 days. Incorporati<strong>on</strong> of these green<br />
manures <strong>in</strong> situ before transplant<strong>in</strong>g rice supplies about 45-60 kg N/ha, besides provid<strong>in</strong>g a<br />
significant residual effect to the succeed<strong>in</strong>g crops. Fertilizer use efficiency is improved when a<br />
legume crop such as Sesbania cannab<strong>in</strong>a or Lathyrus satious is <strong>in</strong>troduced <strong>in</strong> rice-rice cropp<strong>in</strong>g<br />
system. Add<strong>in</strong>g lopp<strong>in</strong>gs of legum<strong>in</strong>ous trees like Leucaena leucocephalla and Glyricidia napus<br />
grown <strong>in</strong> alleys can also meet the crop N requirement substantially. The productivity of rice-rice<br />
cropp<strong>in</strong>g system can be <strong>in</strong>creased by about 1 t/ha besides a net sav<strong>in</strong>g of 30kg fertilizer N/ha by<br />
<strong>in</strong>clud<strong>in</strong>g a short durati<strong>on</strong> legume such as cowpea or greengram and <strong>in</strong>corporat<strong>in</strong>g its residues<br />
<strong>in</strong>to the soil after harvest<strong>in</strong>g the gra<strong>in</strong>s. Similarly, blue green algae culture <strong>in</strong> the rice field can<br />
c<strong>on</strong>tribute about 25 kg N/ha to the rice crop. Algae multiply and cover the field like a carpet<br />
which when <strong>in</strong>corporated <strong>in</strong>to the soil, decomposes and releases N for rice crop. Azolla can be<br />
grown <strong>in</strong> tanks or <strong>in</strong> rice fields and <strong>in</strong>corporated <strong>in</strong>to the soil after 4-6 weeks. Nitrogen<br />
c<strong>on</strong>tributi<strong>on</strong> through Azolla dual cropp<strong>in</strong>g with rice has been worked out to be about 25-30 kg<br />
N.ha. Azolla growth is generally poor without P fertilizati<strong>on</strong> but a substantial improvement <strong>in</strong><br />
growth and yield of rice is achieved when dual cropped Azolla is fertilized with P and<br />
<strong>in</strong>corporated <strong>in</strong>to the soil at a later stage. An applicati<strong>on</strong> of about 30kg P 2 O 5 /ha is adequate for<br />
optimum growth of Azolla. The use of Azolla appears to be promis<strong>in</strong>g <strong>in</strong> the Rabi seas<strong>on</strong> when<br />
there is good water management and availability of other organic sources like FYM and green<br />
manures is limited.<br />

XII. Organizati<strong>on</strong>al set up of Agricultural Research <strong>in</strong> State:<br />
a. Up to the establishment of ICAR :<br />
Prior to the establishment of ICAR (1929) agriculture research <strong>in</strong> the state was under the<br />
c<strong>on</strong>trol of state Department of Agriculture and the Director of Agriculture was the head of all<br />
activities related to development and progress of agriculture. Dur<strong>in</strong>g this period the agriculture<br />
department worked very systematically and efficiently for the crop improvement.<br />
Dur<strong>in</strong>g the tenure of state agriculture department, Government started Agriculture Research<br />
Stati<strong>on</strong> at Nagenahalli <strong>in</strong> 1917 as a dem<strong>on</strong>strati<strong>on</strong> and experimental farm for sugarcane and rice.<br />
This was the first of its k<strong>in</strong>d <strong>on</strong> rice research <strong>in</strong> the entire state. Nagenahalli situated <strong>in</strong> the area<br />
served by Cauvery river (channel) was ma<strong>in</strong>ly emphasized to cater the needs of farmers<br />
cultivat<strong>in</strong>g the rice under canal irrigati<strong>on</strong>.<br />
Similar k<strong>in</strong>d of research activities and dem<strong>on</strong>strati<strong>on</strong> <strong>in</strong> rice as well as <strong>in</strong> other crops was also<br />
set up <strong>in</strong> different parts of the state under varied agro-ecological situati<strong>on</strong>s viz., Coastal areas,<br />
Hilly areas, Malnad areas and ra<strong>in</strong>fed Maidan areas.<br />
b. Up to the establishment of SAU <strong>in</strong> the state.<br />
The first agricultural university <strong>in</strong> the state “University of Agricultural Sciences” was<br />
established <strong>in</strong> 1965 with the head quarters at Bangalore. Later <strong>in</strong> the year 1987 the sec<strong>on</strong>d<br />
agricultural university of the state was started at Dharwad.<br />
The agricultural research activities <strong>in</strong> different parts of the state which was looked after by<br />
the Director of the Department of Agriculture was further strengthened by <strong>in</strong>creas<strong>in</strong>g the No. of<br />
research stati<strong>on</strong>s and appo<strong>in</strong>t<strong>in</strong>g the technical pers<strong>on</strong>nel like Ec<strong>on</strong>omic Botanists to direct and<br />
m<strong>on</strong>itor the research activities.<br />
In 1922, Agricultural Research Stati<strong>on</strong> <strong>in</strong> Mugad, <strong>in</strong> Dharwad district was established to serve<br />
Malnad tract which was grow<strong>in</strong>g very coarse, white kernelled rice under drill sow<strong>in</strong>g. It was<br />
under Bombay prov<strong>in</strong>ce at that time.<br />

Agricultural Research Stati<strong>on</strong> (ARS), Nagenahalli which was established as a dem<strong>on</strong>strati<strong>on</strong><br />
and experimental farm for sugarcane and rice was placed under the immediate charge of an<br />
Assistant Ec<strong>on</strong>omic Botanist <strong>in</strong> 1929. Further, <strong>in</strong> 1931, the rice work <strong>in</strong> the state was reorganized<br />
under the leadership of Late Dr.V.K.Badami, the Ec<strong>on</strong>omic Botanist. Dur<strong>in</strong>g his period<br />
the ma<strong>in</strong> rice work was shifted to Nagenahalli farm, represent<strong>in</strong>g the area fed by Cauvery<br />
channels, work for Malnad area was taken to Maruthur farm and that for summer rices to<br />
Hebbal farm near Bangalore and at Dhadesagar <strong>in</strong> Gulbarga district.<br />
In 1937, Government appo<strong>in</strong>ted a whole time research officer Mr.Sharma, to m<strong>on</strong>itor the<br />
work <strong>in</strong> all rice stati<strong>on</strong>s.<br />
C<strong>on</strong>sequent to <strong>in</strong>crease <strong>in</strong> the channel-fed area, ARS, Nagenahalli that was established as a<br />
dem<strong>on</strong>strati<strong>on</strong> and experimental farm for sugarcane and rice was c<strong>on</strong>verted <strong>in</strong>to paddy<br />
breed<strong>in</strong>g stati<strong>on</strong> <strong>in</strong> 1938 for <strong>in</strong>vestigat<strong>in</strong>g the manural and cultural practices and <strong>on</strong> the c<strong>on</strong>trol<br />
of diseases besides breed<strong>in</strong>g work <strong>in</strong> rice.<br />
The paddy breed<strong>in</strong>g stati<strong>on</strong> at Mangalore, formerly under Madras presidency (state) was<br />
opened <strong>in</strong> 1942 for the improvement of rice for coastal area of South Canara district.<br />
Dur<strong>in</strong>g 1948, at Kumta <strong>in</strong> North Canara (Uttar Kannada) district a research stati<strong>on</strong> was started to<br />
work for comb<strong>in</strong><strong>in</strong>g the quality and resistance to blast disease. Further, Kumta (salt land) stati<strong>on</strong><br />
was opened to develop salt-land rice varieties for south K<strong>on</strong>kan coastal area. At Sirsi, which is<br />
also <strong>in</strong> North Canara district another paddy research stati<strong>on</strong> was opened for improvement of<br />
rice crop of upghat (hilly) areas.<br />
At P<strong>on</strong>nampet <strong>in</strong> South Coorg district, Agricultural Research Stati<strong>on</strong> was started <strong>in</strong> 1951 for<br />
tak<strong>in</strong>g up breed<strong>in</strong>g and agr<strong>on</strong>omic aspects of hilly rice under a scheme f<strong>in</strong>anced by ICAR.<br />
