Abstract
Accurate estimation of crop water requirements (ETc) is essential for the irrigation scheduling and water management of Yazagyo irrigated area, Myanmar. FAO defined the crop water requirements as the depth of water needed to meet the water loss through evapotranspiration of a crop, being disease-free, growing in large fields under non-restricting soil conditions, including soil water and fertility, and achieving full production potential under the given growing environment. It is essential to have a clear idea about the optimum water requirement for proposed crops under adaptable climatic conditions. The optimal crop water requirement mainly depends upon the accurate estimation of evapotranspiration and crop coefficient. To perform in this study, firstly Meteorological data of Kalay Station, in Myanmar are collected from 1995 to 2018. On the other hand, the different kinds of crops such as paddy, groundnut, sesame, sunflower, bean, and pea are considered for the estimation of seasonal crop water requirements for this area. Based on the crop growth stages in this area, crop coefficient curves are developed and crop coefficients are determined for each crop according to FAO manual. By using monthly crop coefficients and CROPWAT 8.0 software, reference crop evapotranspiration, crop water requirements and total irrigation requirements are presented for the selected area.
