Abstract

In order to study the effects of UREA FOLIAR SPRAYING at different growth stages on Sabalan DRYLAND WHEAT GRAIN YIELD and PROTEIN CONCENTRATION, experiments were conducted and set up in RCBD with 6 tretments and 3 replications during 1998-2001. The study was conducted at Maragheh Dryland Agricultural Research Station. Treatments included: control (no sprayings), spraying of a 5% urea solution (20 kgN.ha-11) at tillering, shooting, flag leaf and pollination stages, and UREA FOLIAR SPRAYING (5%) with 2 l.ha-1 2.4.D herbicide at tillering stage. The same nitrogen fertilizer rate (50 kgN.ha-1) was placed in soil for all treatments at planting time. The results showed that the effects of UREA FOLIAR SPRAYING differed significantly on wheat grain PROTEIN CONCENTRATION. The highest grain PROTEIN CONCENTRATION (21.1%) was obtained from UREA FOLIAR SPRAYING at shooting stage. UREA FOLIAR SPRAYING at flag leaf stage not only increased grain PROTEIN CONCENTRATION (18.2%), but also increased GRAIN YIELD (24%) compared to control treatment. It can be concluded that UREA FOLIAR SPRAYING at different growth stages can affect differently the grain PROTEIN CONCENTRATION, protein and GRAIN YIELDs in DRYLAND WHEAT. The recommended time for UREA FOLIAR SPRAYING is flag leaf stage, which can increase grain PROTEIN CONCENTRATION, protein and GRAIN YIELDs compared to other growth stages.
