Abstract:

The knowledge of crop water requirement and Irrigation scheduling is an important practical consideration for designing and managing an irrigation system. A field study was conducted to find out the irrigation scheduling of Mustard crop by Climatological method and its comparison with CROPWAT model from rainwater harvested through plastic lined pond during the year 2018-19 at PFDC-PET farm of the BAU Ranchi Jharkhand. Through pan evaporation method, total Crop water requirement was estimated 323.23 mm out of which 300 mm water was given through irrigation. Irrigation was scheduled through climatological method with IW/CPE ratio 0.9 and depth of irrigation kept at 6cm through five irrigations at 22, 42, 63, 82, and 93 DAS. Total yield obtained through climatological method was 922 kg/ha. The irrigation scheduling and net irrigation requirement were compared with CROPWAT model, based on climatic data, crop data and soil data of the region. Total gross irrigation requirement through the CROPWAT model was 252.2mm with total four irrigations at 36, 52, 68, 80 DAS and yield was 1162 kg/ha. So, for better water use efficiency CROPWAT model can be used in the region.
