  Population growth, high water competition (demand), and the effect of climate change have caused water shortage problems in the Nile basin. Therefore, improving water management and determine the water requirement of field crops is substantial. In this study, the Food and Agricultural Organization (FAO) CROPWAT 8.0 simulation model, local climate, and soil data were used to determine crop water requirement (CWR) and irrigation scheduling of wheat crop at Koga and Rib irrigation scheme. The CROPWAT Penman-Monteith and the United States Department of Agriculture (USDA) soil conservation service method were used to compute the reference evapotranspiration (ETo) and effective rainfall respectively. The result of the study showed that reference evapotranspiration was varied from 4.86 mm day-1 (maximum) to 3.14 mm day-1 (minimum) at Koga while at Rib it ranges from 4.67 mm day-1 (maximum) t..
