Abstract

This experiment was carried out at Agric. Exp. Stn. of Gonbad. The experiment design was a Randomized Complete Block arranged in a strip-plot. Vertical factor consisted of four irrigation levels (I0= without irrigation, I1= Irrigation at flowering, I2= Irrigation at grain filling and I3= Irrigation at flowering and at grain filling). Four rates of N fertilizer (0, 30, 60 and 90 kg N (as urea)/ha) were horizontal factor. The results revealed that increasing N fertilizer significantly increased grain YIELD and protein content and YIELD, biologic YIELD, harvest index, while N.U.E. significantly reduced. The highest YIELD was obtained at 90 N kg/ha, however it had not any significant difference with 60 kg N/ha. Irrigation at both flowering and filling period (I3) significantly increased grain YIELD, grain per spike, grain YIELD and protein content and YIELD, N.U.E. while other traits reduced. Interaction of N fertilizer and irrigation was non-significant for all traits with the exception of protein content and N. U. E.
