Muralidaran, V. | Krishna, K.V.S.M.
The study critically examines the operational features and the interplay of factors in the Mahi-Kadana System responsible for the current process of surface water distribution, and to ascertain whether such a distribution and resultant utilization i) interseasonally, and ii) in relation to the abundant groundwater available, can result in a realization of the overall productivity benefits of the project command. The specific objective was to analyze the performance of two representative secondary canals in terms of water deliveries and its impact on farm production, with particular reference to location and to well and/or tubewell use in irrigated agriculture. The study has produced some methodological innovation. It has succeeded in developing and applying a seasonal moisture index for wheat, on the lines of the one constructed for rice which analyzes spatial distribution and the productivity of irrigation water application. In summarizing the evidence that has emerged, the discussion is conducted with reference to certain characteristics of the entire system
