Abstract: Water stress due to its severity badly effects productivity in legumes.Despite its global importance soybean production suffer the problems of water stress causing damages at plant development.So, the current study aimed at assessing the alleviation of adverse effects of water stress on soybean by using exogenous osmoprotectants and compost application.A greenhouse experiment was conducted at plant nutritional physiology laboratory, Hiroshima University, Japan in 2011-2012.The treatments as follows, (a) water stress at different soil moisture levels consisting of ( 100% as control , 75% and 50% ), (b) compost fertilizer ( Control , 24 t/ha) and (c) exogenous proline and glycine betaine at the concentrations of (Control and 25Mm) for each.The results indicated that, water stress significantly reduced the seed yield and quality traits.Special attention was paid to the tolerance against water stress was observed, the improvement of water tolerance resulted from proline, glycine betaine and compost were accompanied with improved number of branches, number of pods, 100 seed weight and seed yield per plant.As well as, reduce adverse effects of drought on protein and oil content.These results clearly demonstrate that could be used to reduce the harmful effect of water stress on seed yield and quality aspects of soybean and reduce the amount of water used for irrigation.
