In controlled-condition field trials across South Asia, zero-tillage (ZT) has demonstrated considerable scope for enhancing wheat productivity in the Indo-Gangetic Plains (IGP) while using less energy and irrigation water. However, studies that quantify the impact of ZT in farmers’ fields are scarce, especially in the less productive and densely populated(More)
Zero-tillage (ZT) is a proven technology for enhancing wheat productivity and, hence, food security in the Indo-Gangetic Plains, while reducing production costs. However, very few farmers possess their own tractors much less the specialized seed drills required to implement the technology. As a consequence, adoption of ZT largely hinges on affordable access(More)
