Effects of tillage and mulch on the growth, yield and irrigation water productivity of a dry seeded rice-wheat cropping system in north-west India

The results suggest that in a dry seeded rice-wheat cropping system, surface retention of rice residues can improve the growth of ZT wheat right from the first crop, although this did not affect yield in the first three years. However, whether there is an adverse carry over effect of the rice residues on DSR requires further investigation.
