Abstract: In the intensive rice-wheat system (RWS) of the western India, direct dry seeding of rice, zero tillage in both rice and wheat, and residue recycling from rice can greatly reduce water and labour input, eliminate residue burning, and potentially conserve natural resources. The objectives of this 2-year field study conducted at the Project Directorate for Cropping Systems research Modipuram, India in 2005 to 2007 were to determine the effects of tillage, crop establishment methods and residue on crop growth, physiology, grain yield, water productivity, and economic profitability in RWS. The treatments included six combinations of rice establishment and tillage in rice with and without Sesbania co-culture. In the following season wheat was raised as zero-till (ZTW) in all the treatments and the residue from previous rice was either removed or retained on the soil surface without incorporation.
