CONTEXT: Intensive cropping and elevated input use to achieve high crop yields have resulted in the injudicious use of resources and a consequent reduction in profit margins for farmers in the Eastern Gangetic Plains (EGP) region of South Asia. In this region rice-wheat (RW) under conventional tillage (CT) management is the most widely cultivated cropping system. While conservation agriculture (CA)-based management practices have been demonstrated to improve cropping system performance, they are considered by many farmers to be risky, and adoption of CA in rice-based cropping systems is low. There has been little agronomic research into alternative cropping systems to develop diversification options appropriate for the EGP. OBJECTIVE: We hypothesized that shifting from a conventional RW system to crop establishment practices which incorporate CA principles, combined with alternative crops could improve the whole cropping system in terms of productivity, profitability, and nutritional security (as crop protein).
