Abstract

In order to evaluate the effects of the amount and APPLICATION TIME of NITROGEN FERTILIZER on growth, physiologic characteristics, YIELD and YIELD components of WHEAT (Tritium aestivum. L. cv. Zagroos), an experiment was conducted under rainfed condition at Gorgan province, Iran in 1999-2000.The treatments consisted of the factorial combination of five nitrogen rates (N1=0,N2=30, N3=60,N4=90 and N5=120 Kg.N/ha-1) and four different time of nitrogen application, which were T1= all preplant (Pp), T2= 1/3pp + 2/3 tillering, T3= 1/3pp + 2/3 stem elongation and T4= 1/3pp + 1/3 tillering+1/3 stem elongation. The experiment was arranged as a randomized complete block design with three replications. The results showed that grain and biologic YIELDs increased second order polynomial with increasing N fertilizer. The highest grain YIELD and biologic YIELD were observed in N4treatmentwith 4525.1 and 10386.6 kg/ha-1 respectively. The increase in grain YIELD with increasing N application was due to increase in spicule/m-2 and grains. spicule-1. The plant height, TKW and spicule-2 were significantly affected by the time of N fertilizer application at 5% probability level.
