Abstract:

Due to overexploitation of available water resources, it has become very important to define appropriate strategies for planning, development and management of water resources of the country. The study aims to develop an optimal irrigation scheduling, to increase crop yield under water scarcity conditions. The crop water requirement was found to be 304 mm and irrigation requirement 288.2 mm. On refilling soil to field capacity with irrigation at critical depletion, irrigate at a given ET crop reduction per stage and irrigate at fixed interval per stage at 70% field efficiency gave a yield reduction of about 0 %, 14.9%, 25.1% respectively. Irrigation should be done at the critical depletion to achieve 0% yield reduction of maize and maximum rainfall efficiency. The research shows that the irrigation management model can effectively and efficiently estimate the crop water requirements. The model, that calculates evapotranspiration and crop water requirements, allows the development of recommendations for improved irrigation practices, the planning of irrigation schedules under varying water supply conditions and yields reduction under various conditions.
