Biofertilizers are very important in biogeochemical cycles and have been used for crop production for decades. Their interactions in the rhizosphere are the determinants of plant health and soil fertility. They help to supply nutrients to crops, to stimulate plant growth through production of phyto-hormones, to control or inhabit the activity of plant pathogens etc. The present investigation was aimed at determining the effect of individual and combination treatments of bioinoculants i.e. Azotobacter and PSB on nodulation of two cultivars G-65 and S-12 of Phaseolus aureus. Changes in the level of phytohormones were also determined in roots inoculated with biofertilizers. When different individual and combination treatments of bioinoculants were applied as seed coating treatments and it was observed that higher the doses of bio-inoculants in all the replicates, resulted in more number of nodules (nodulation) in both cultivars as compared to their controls. But it was more significant in G-65. Hence nodulation help in increasing the soil fertility, so "More the nodules more will be the fertility of soil, hence more the crop yield"
