In order to study effects of nitrogen fertilization and cultivars on some of traits of different barley an experiment was conducted at Isfahan in 2012. The experimental was split plot in a randomized complete block design with three replications. In this experiment, different levels of nitrogen in the main plots included four levels (0, 50, 100 and 150 N kg/ha (urea)) and barley cultivars including Nosrat, Reyhan and Bahman were placed in the subplots. Results showed that the effect of nitrogen on plant height, number of tillers, number of fertile tillers, number of fertile tillers, length and peduncle length were significant. Treatment fertilizer of 150 kg/ha nitrogen maximum number of tillers, number of fertile tillers per square meter, plant height, peduncle length and length compared to the other treatments. Also Nusrat cultivars had the highest average in all traits.
