    Abstract: In order to evaluate the effect of urea foliar application of urea on yield and yield components of Kimia cultivar grain sorghum, a factorial experiment was carried out using Randomized Complete Bloke design with 3 replicates and 12 treatments in Saatlo Agricultural Research Center in Uremia, Iran. The factors in this research were foliar application stages (knee stage, tassel emergence, knee stage + tassel emergence) and the foliar application percent (0, 50, 75 and 100%). The results of data analysis showed that foliar application has significant effect on some characteristics such as grain yield, number of grains in a panicle but no effect on length, weight and thickness of panicle. In treatment stages knee stage has higher result in grain yield as number of grains in a panicle but foliar application in tassel emerges is more effective in thousand kernel weight.
