A study was established for determining the effect of nitrogen (urea) fertilizer method and time of application on the growth and yield of Sepideh and Kimia grain sorghum varieties. The experiment was conducted as a factorial-split design with four replications in Karaj (Iran) during 2003 growing season. The main plots were allocated to variety and fertilizer application methods (banding and broadcasting) and the subplots were assigned to fertilizer application time viz., at sowing and eight-leaf stages, sowing and booting stages and sowing, eight-leaf and booting stages. There was also a nitrogen fertilizer free treatment. The results of the experiment revealed that in most of the cases, responses of the sorghums varieties to broadcasting method of N fertilizer application were better than its banding. The time of N fertilizer application had different effects on similar traits of the sorghums. Variety, interactions of variety x fertilizer application method and varietyxfertilizer application time showed that for most traits Kimia variety was better than Sepideh.
