Abstract:

The available water decreases as world demand for water increases for various purposes such as industrial, agriculture hydropower. To improve the water use efficiency, there is a need to modify traditional irrigation scheduling. In the present study, the CROPWAT model was used to estimation the irrigation scudding for rice and cotton crop to improve water use efficiency. From the analysis, it was found that reference evapotranspiration was almost directly proportional to the radiation and sunshine hours and inversely proportional to the relative humidity. The crop evapotranspiration, effective rainfall and the crop water requirement varied from 0.74 -5.57 mm/day, 0.1-55.1 mm/dec and 0-157 mm/dec, respectively. The CROPWAT model appropriately estimate the reference evapotranspiration, effective rainfall and other parameter for irrigation scheduling, which makes this model as a best tool for irrigation planning and management for all crop and climatic condition.
