Abstract

Improving WATER PRODUCTIVITY is vital to sustain and raise crop production. In order to investigate the effect of water and nitrogen rates on WHEAT, a field experiment was conducted as split plot arranged in arandomized complete block design (RCBD) with three replications, during 2000-2002 at Maragheh. Rainfed Research Station, The treatments included four levels of DEFICIT IRRIGATION (rainfed, %33 F.I., %66F . I, and Full Irrigation (F.I)) and five nitrogen rates (N0, N30, N60,N90, and N120kg.ha-1).Yields of rainfed conditions varied with seasonal rainfall and its distribution, with all main factors having significant effects on it. With irrigation, yield response to N application was generally significant up to 90kgNha-1. Optimum level of DEFICIT IRRIGATION was realized with %66 of full irrigation treatment (%27.3 decreases in full irrigation) which led to maximum irrigation WATER PRODUCTIVITY and with 4467kg.ha-1 grain yield. WATER PRODUCTIVITY based on irrigation water alone (WPI) and both irrigation - plus rainfall (WPI+p) at 90 kg.N.ha-1 over the two seasons were 9.58 and 27.92kg mm-1, respectively.
