Rice is a crop of tropical climate. However, it is also grown successfully in humid to sub-humid regions under subtropical and temperate climate. Rice is cultivated in almost all types of soils with varying productivity. Under high temperature, high humidity with sufficient rainfall and irrigation facilities, rice can be grown in any type of soil. The major soil groups where rice is grown are riverine alluvium, red-yellow, red loamy, hill and sub-montane, Terai, laterite, costal alluvium, red sandy, mixed red and black and medium and shallow black soils. Depending upon the climate and water availability rice is grown in all the three seasons, i.e. Kharif, Rabi and summer. Depending upon the variety crop duration vary from 100 to 150 days. In northern and western India rice is grown mainly in Kharif, while in southern and eastern India it is grown round the year in three seasons with varying sowing time and periods.
