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