Abstract :
In order to determine seed yield, biological yield and harvest index of soybean cultivars in different treatments of planting Dates an experiment was conducted as a split plot arrangement based on randomized complete block design with 3 replications in Shahrekord region, this research was conducted in 2010-2011 in research farm, Shahrekord research station, Shahrekord city, Shahrekord province, Iran. main plots were planting dates ( 5 May, 20 May, 22 June, 6 July ) and sub plots were cultivars ( Enterprise, Williams, M9 , M7 ). planting date was significant on plant height, the number of pods per plant , 100 grain weight, seed yield, biological yield and harvest index. Cultivar also had significant influence on plant height, the number of seed per pod, 100 grain weight, biological yield and harvest index. The interaction of planting and cultivar was significant on seed yield and oil yield. First planting date ( 5 May ) had obtained the maximum seed yield and oil yield in comparision other planting dates. Williams also had obtained the maximum the number of secondary branches, the number of pods per plant, the number of seed per pod seed yield and biological yield. It seems that cultivation of Williams and 5 May planting date is suitable for this region.
