Effect of bio fertilizers application on protein and oil in soybean

A field experiment was lay out in order to evaluate the effects of different biofertilizers on protein and oil of soybean in Iran. The experiment was a factorial design with three replications. Treatments were four nitrogen biofrtilizers (control (N1), Nitroksin (N2), Azotobacter (N3) and Supernitroplat (N4)) and three phosphate biofrtilizers ( control(P1), Biosfer phosphate (P2) and Phosphate barvar2 (P3)). In this study seed protein and seed oil were determined. Results showed that that there were significant differences in the response of soybean to the effect of treatments on seed protein and oil. However, seed protein and oil significantly higher in application of Azotobacter treatments. The highest among the phosphate biofertilizers, seed protein and oil were belonged at application of Phosphate barvar2. In final results of this study reviled that application nitrogen and phosphate biofertilizers specially Azotobacter and Phosphat barvar2 increased seed protein and oil.
