Abstract:
Overexploitation of available water resources due to increasing population has made vital to plan efficient use of water and better irrigation practices like scheduling. The study was carried out for maize to develop an optimal irrigation scheduling to increase crop yield. The crop water requirement was found to be 365.2 mm and irrigation requirement 275.3 mm. Irrigation should be carried out at critical depletion to achieve 0% yield reduction of crop and maximum rainfall efficiency. The research showed that the irrigation management model could effectively and efficiently estimate the crop water requirements. It allowed to develop the recommendations for improved irrigation practices and the planning of irrigation schedules under varying water supply conditions.
