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

Depletion and/or degradation of natural resources, increasing farm labour scarcity, and high production cost are major threats to the rice-wheat cropping system of north-west India. Conservation agriculture (CA) is a potential solution which can be achieved by switching from puddling then transplanting of rice to dry seeding (DSR), together with changing from conventional tillage (CT) to zero tillage (ZT) for wheat with surface retention of rice...
