In order to investigate the effect of seed and nitrogen fertilizer levels on some agronomic and morphological traits of wheat cultivars and lines in Ardabil, a randomized complete block factorial experiment with three replications at Ardabil Agricultural and Natural Resources Research Station During the 97-98 crop years. Experimental treatments consisted of two levels of seed density (400 and 500 seeds / m 2) in main plots, 8 wheat cultivars (Pishgam, MihanHeidari, Zarrineh, Cascogene, Simit 1010, Simit 1018, Simit 1007 and Simit 1012) and four Urea fertilizer levels (0, 50, 100 and 150 kg ha-1) were in the sub-plots. The results showed that the triple effect of density on cultivars in fertilizer was significant for all traits such as 1000-grain weight, spike length, peduncle length, plant height and grain yield at 1% probability level. The highest densities were observed in the combination of 500 seed with Zarrineh and fertilizer level of 150 kg ha-1, with the same combination of 500 seeds and 4 fertilizer treatments as well as 400 and 8 fertilizer treatments in the second group. Also, the treatment combination of 400 seed density with cultivar 6 and fertilizer 2 had the lowest and with the treatment combination of 500 seed density with cultivar 6 and fertilizer 3 were the same in the same group. So, Zarrineh cultivar had the highest yield under the conditions of this experiment.
