Abstract :

The amount of water required by the plant is an important factor in the growth of soybeans and has a significant effect on its yield. The amount of soil moisture for optimal growth of each plant should have an optimal level that getting more or less than this optimal level, plant growth decreases and soybean yield is affected by the total number of pods per shrub, the number of seeds per pod and the weight of each seed To investigate the effect of drought stress on physiological traits of soybeans; Drought stress reported a significant reduction in the amount of the photosynthesis and grain yield Increasing irrigation and rain water consumption efficiency is affected by the correct application of chemical fertilizers, especially nitrogen. In addition, nitrogen deficiency after water shortage is the most important factor in reducing crop production, especially cereals. Among the yield components, the number of pods per node was significantly affected by nitrogen fertilizer, so that by increasing the amount of nitrogen, the number of pods per node was increased. In general, optimizing water and fertilizer consumption in crops, especially oilseeds, can increase agricultural production as well as save water resources.
