To evaluate the effects of drought and foliar micronutrients on yield, protein and oil content of soybeans, Split factorial randomized complete block design with four replications in crop year 2015-2014 was conducted at the research farm of Islamic Azad University, Khorramabad. Stress factor in three levels (control, tension and stress in flowering stage to the stage of pod) as the main factors and the factors at two levels (the M7 and the M9) and foliar application of micronutrients in three levels (non-sprayed, at the stage of flowering and foliar spray at flowering and pod filling stage) factorial trial were considered as secondary factors. The results showed the effects of drought stress, foliar application of micronutrients and the statistical level of 1% and sprayed on the surface of the interaction of drought stress in 5% had significant effect on grain yield. So that the highest grain yield of 3192 kg per hectare with an average normal irrigation and the lowest yield related to stress at flowering stage with an average of 2211 kg per hectare. The highest yield and quality of soybean in non-stress conditions, flowering and pod filling stage and sprayed in two digits (M7) were the most sensitive growth stages of soybean to drought stress is the flowering stage.
