Abstract |
The research was conducted at the agricultural Scientific Research Center, AL-Fourat University in the Governorate of Deir Ezzor. The experiment was laid with randomized complete block design with three replications, and the existence of two factors. The first factor is the drought stress treatment which have been applied as follows: Control: the plant of the experimental plot have been irrigated once each ten days. The first treatment: the plant of the experimental plot have been irrigated once each fifteen days. The second treatment: the plant of the experimental plot have been irrigated once each twenty days. The third treatment: the plant of the experimental plot have been irrigated once each twenty-five days. The second factor is the studied cultivars (Sb44, Sb321, Sb330). the following attribute have been studied: The number of days to flowering and physiological maturity, Plant height, leaf area index, number of pods per plant, 1000 - seed weight, seed yield, Harvest Index. The results have proved the existence of significant differences between the drought stress treatment and the studied cultivars in most attributes, while the effect of the alternate interaction between them wasn't significant except for the Plant height, and the seed yield. The cultivar Sb44 surpassed all other cultivars in seed yield, 1000 - seed weight, Harvest Index. while the cultivar Sb330 surpassed all other cultivars in Plant height, number of pods per plant, and it showed early flowering and maturity.
Key Words: Soybean (Glycine Max L.), drought stress, Harvest Index, cultivars, seed yield. |
