Tillage System, Crop Residue s and Nitrogen to Improve the Productivity of Direct Seeded Rice and Transplanted Rice

Abstract

Rice is grown by different techniques for higher productivity with judicious use of inputs and natural resources. Transplanting of paddy seedlings is common method of crop establishment in the irrigated rice systems of Asia but transplanting is labour intensive (30 persons/ha/day). The preparation of land for transplanting paddy (puddling) consumes about 20-40 % of the total water required for growing of crop and subsequently poses difficulties in seed bed preparation for succeeding wheat crop in rotation. It also promotes the formation of hard pan which effects rooting depth of next crop. So, in this paper discussed the different methods of establishment of rice, sowing of rice in the crop residue of wheat with different tillage systems and use of nitrogen for higher productivity of rice.
