temperature seldom falls below 18°C. The State is exposed to both South West and North East
monsoons.
Soil type:
Rice is a semi aquatic plant and grows best under low land condition. In India, it grows in almost
all types of soils- alluvial, red, lateritic, laterite, black, saline and alkali, peaty and marshy soils and in acid
soils. But the soils having good water retention capacity with good amount of clay and organic matter are
ideal for rice cultivation. Clay and clay loam soils are most suited.
Duration groups in rice:
i. Very early About 100 days
ii. Short 100-120 days
iii. Medium 121-140 days
