Abstract
An experiment was conducted in Ilam, Iran, in order to study the effect of drought stress on yield and its associated traits of soybean cultivars, during 2010-2011 cropping season. The experiment was conducted as split plot arrangement based on Randomized Complete Block Design with three replications. Drought stresses during the 4 leaves stage (flowering, podding and seed filling stages) were assigned as main plots and three cultivars (M7, M9 and Hobit) were chosen as sub plots. The results showed that drought stress and cultivar were significant on plant height, fertile pod. Plant-1, seeds.plant-1, seed yield, biological yield, hundred kernels weight, seedspod-1, harvest index, oil and protein percentage. M9 cultivar had the best performance in seeds per pod, 100-seeds weight, seed yield and biological yield. The lowest seed yield was produced in the drought stress during the seed filling (2682 kg.ha-1) and flowering stages (2918 kg.ha-1), respectively. Under stress and non-stress conditions, the Hobit cultivar produced higher oil percentage. Protein percentage of M7 cultivar was higher than other cultivars. It can be concluded that, M9 cultivar was better than the other cultivars and the grain filling stage was the most sensitive phonological one of soybean to drought stress in this region.
