Sorghum ( Sorghum vulgare L ) is important crop in the arid and semi arid regions. A 2-year field experiment was conducted to determine the effects of nitrogen levels (0, 6, 12 and 18 kg/da N) on some yield and yield components of four sorghum cultivars (Grazer, Early­ Sumac. Rox and Gozde-80). The experiment was a split plot with [hree replications. Mai n plots were assigned to nitrogen levels (0, 6, 12 and t 8 kg/da) and sub-plocs were assigned to sorghum (Rox, Grazer, Early-Sumac and Gozde-80) cultivars. In experimenc, green herbage and dry matter yields, plant height, stem, leaf. and pamcle ratio and crude protein  ratio  and  crude protein yields were determined.

Applied N increased the green herbage, dry matter yields and plant heights, but it not effected on the  proportions of leaf. stem and panicle. It  was  concluded  that  ..Grazer"  was  the most favorable cuitivar under this cond itions. Optimum race of nitrogen  was  12  kg/da  in irrigated   conditions.
