The most widely adopted resource-conserving technology in the Indo-Gangetic Plains (IGP), particularly in India, is Zero-tillage (ZT). CIMMYT's role with regard to ZT in India was to make the diffusion process faster and more efficient. CIMMYT facilitated technology introduction by helping with the design experiments for technology testing and local adaptation. Using conservative benefit estimates the program yielded a net present value (NPV) of US$94 million; equivalent to a benefit-cost ratio (BCR) of 39 and an IRR of 57%. The economic surplus primarily benefited consumers, at 65%, compared to producers, at 35%.
