In the wet system of cultivation rice is grown as a wet crop right from the start generally in tracts which enjoy assured supply of water .In this system the field is brought to a soft puddle by respeated ploughing with 5-7 cm standing water. Rice fields with sandy to sandy loam soil are ploughed in summer and again ploughed once or twice after letting in water to get the requisite puddle. Heavy soils of clayey nature are not generally opened in summer. These soils are usually ploughed a few days before transplanting. Optimum depth of puddling is found to be 10 cm in clay to clay-loam types of soil.
