Abstract

In order to study the effect of N fertilizer and DROUGHT stress on biological yield, GRAIN YIELD and yield components of different WHEAT CULTIVARs, a factorial experiment in a randomized compeletely block design was conducted in 2003-2004 with four replications, at Islamic Azad University, Shushtar branch. The treatments included WHEAT CULTIVARs (Chamran, Showa and Falat), N fertilizer in two levels (50 and 150 kgN. ha-1) and two levels of DROUGHT stress (without stress, and stress in grain filling stage). Chamran and Falat were bread wheats and Showa was durum wheat. Results indicated that in DROUGHT stress, Chamran had higher GRAIN YIELD (5584 kg/ha) compared to Showa (5332 kg/ha) and Falat (4821 kg/ha). The increasing NITROGEN caused an increase in GRAIN YIELD by 45% compared to the treatment of lower consumption of NITROGEN. Responseto N fertilizer in Chamran and Showa was more than that of Falat cultivar.Spike number in square meter, grain number per spike and thousand grain weight were effective in increasing GRAIN YIELD.
