Field experiment was conducted during Kharif, 2017 at Farm of Agronomy, RCSM College of Agriculture, Kolhapur. To study the effect of dual inoculation of Bacillus subtilis and Bradyrhizobium japonicum along with graded levels of chemical fertilizers on plant growth parameters of soybean (Glycine max L.) The dual inoculation of Bacillus subtilis and Bradyrhizobium japonicum along with 75 % nitrogen and phosphorus significantly superior over rest of the treatment in ameliorating growth parameters. Which recorded highest germination (86.94 %), height of plant at 50 % flowering (58.32 cm), number of main branches at 50 % flowering (7.66), dry plant weight at 50 % flowering (28.39 g plant-1), number of root nodules plant-1 at 50 % flowering (120. 37), dry weight of root nodules (1.60 plant-1) and dry matter yield at harvesting (30.90 q ha-1). However, above treatment did not differ significantly from those recorded with B. japonicum and B. subtilis along with 100 % recommended dose of fertilizers and un-inoculated control.
