The water deficiency conditions of the soil significantly depress development of plants, grain yield, N content in the yield and nodulation. The best results were observed with the manure treatment. Mineral nitrogen depressed nodulation process. Organic fertilizers decrease the negative effect of the drought on the grain yield and nodulation.The received results suggest that drought can be used in the studies related to the introduction of stress factor in the different stages of plant development and its effect on N2 fixation.
