| Abstract The study aims to develop computer model that simulates how a specimen by which to know the impact of Application uniformity on the soil surface and the lack of operating time for the sprinkler on the efficiency , adequacy ,usefulapplication uniformity of each irrigation and productivity. The model buildingadopted on the principle of water balance in the field and has been applied to sesame summer crop by using available field data for the water distribution under sprinkler system. The model also adopted the climate data and the type of crop and soil. The study show that useful uniformity coefficient more thanuniformity onthe soil surface and the value of the efficiency and adequacy and useful uniformity vary from one irrigation to another and start to decline with the stability of the root zone irrigation after irrigation, and the results show that productivity depends on the efficiency , adequacy and useful uniformity that are affected in turn byuniformityand the time of application.the water use efficiency increased by increasing the application uniformity and decreasing the sprinkler operating time. | ||
