A study was conducted in the pastures of the College of Agriculture in Erzurum for seven years starting in 1986 in order to investigate the effect of seasonal (fall and spring) N application (0,40, 80 and 120 kg/ha) on the growth of crested wheatgrass. This experiment presented data concerning the canopy and root growth of crested wheatgrass in 1993. Nitrogen application in both fall and spring increased shoot and root weight but decreased the root/shoot ratio and vegetative shoots. Reproductive shoots and the total shoot number of also decreased. Shoot number was less affected in the fall than in the spring fertilization
