The study was carried out to know the effect of combined inoculations of Plant Growth Promoting Rhizobacteria (PGPR) on the productivity of soybean under pot culture experiments. The seed inoculations of Rhizobium, phosphate solubilizing bacteria (PSB) and general rhizobacteria were tested in different combinations on the yield and yield components of soybean. All the inoculation treatments showed better plant growth, nutrient uptake and yield compared to uninoculated control. Among various combinations, single inoculations performed better than uninoculated control while dual inoculations found better over single inoculation treatments. Combined inoculations of three beneficial organisms viz., Rhizobium, Azospirillum and PSB was more superior over both single and dual inoculations, however combined inoculation of four organisms was on par with combined inoculation of three organisms with respect to plant growth, yield and nutrient uptake.
