Increasing scarcity of labour, water, and energy and rising cost of production, along with climate variability, are major challenges for the sustainability of rice-wheat system in the northwesten Indo-Gangetic Plains (IGP). Direct-seeded rice (DSR) with best management practices provided equivalent or higher yield and 30-50% lower irrigation water use than those of farmer-managed puddled transplanted rice (CT-TPR). DSR showed overall net benefit of up to 4000-5000 ha-1 as compared to puddled transplanted rice.
