Abstract

In order to evaluate the effects of nitrogen (N) rate and time of N application on the GRAIN PROTEIN content and nitrogen use efficiency of WHEAT (Triticum aestivum.L. var:Zagroos), an experiment was conducted under rainfed condition in Gorgan, Iran, in 1999-2000. The treatments consisted of the factorial combination of five nitrogen rates (N1=O, N2=30 , N3=60, N4=90 and N5=120 Kg N ha-1) and four different time of nitrogen application(T1= all prior to planting, T2= 1/3 prior to planting + 2/3 at tillering, T3= 1/3 prior to planting + 2/3 at stem elongation and T4= 1/3 prior to planting+ 1/3 at tillering +1/3 at stem elongation).The experiment was arranged as a randomized complete block design with three replications. Results showed that the GRAIN PROTEIN content and protein yield increase hyperbolically with increasing N fertilizer. However, there was significant reduction in nitrogen harvest index, N UTILIZATION EFFICIENCY (NUtE), agronomic efficiency (AE), physiologic efficiency (PE) and apparent recovery (AR) with increasing amount of N fertilizer. The GRAIN PROTEIN content, NUtE and PE were significantly affected by the time of N application.
