Some Factors Affecting Nodulation And Nitrogen Fixation Of SOYBEAN (GLYCINE MAX)

Study the effect of inoculating three varieties of soybeans with 8 strains of Rh. Japonicum on nodulation and efficiency of nitrogen fixation. The occurrence of Soybean root nodule bacteria in some Ergyptian Soil and the effect of inoculationg these soils were also investigated. In addition, the effect of various concentrations of NaC1 and Na2So4 on nodulation and Nitrogen.
