Crop management research and extension: The products and their impact on productivity
This study presents a methodology (in five steps) for assessing the impact of information and technologies generated by a crop management research (CMR) program. The methodology is demonstrated by estimating the return to CMR conducted in the Yaqui Valley of Mexico between 1977 and 1987. The overall rate of return to the investment in CMR was estimated to be 16% in real terms. This is somewhat lower than observed for the other rate of returns studies, partly because the entire portfolio of research projects, many of which were not productive for the period under evaluation, was evaluated. For integrated pest management (IPM) and ridge planting, the two successful research projects in the CMR program that produced the entire flow of benefits, the rate of return considerable amount of CMR was apparently underproductive argues for more design and implementation of a program aimed at monitoring the impact of CMR on farmers' practices are provided.
