Abstract: Rhizobium R7, R10 and R14 was selected for present study. These strains were already, characterized and produced HCN, Siderophore, IAA and P-solubilizing and enhanced the plant growth in Mucuna pruriens (Deshwal et al., 2011a). Field experiment was conducted and four sets of treatment were prepared i.e. treatment I – Rhizobium R7; treatment II – Rhizobium R10; treatment III – Rhizobium R14; treatment IV- Non-bacterized seed. Data showed that all Rhizobium strains improved plant growth and productivity. Maximum seed germination was observed in Rhizobium R7 which was 122.78% as compared to control. Maximum shoot length was observed in Rhizobium R7 but maximum root length was observed in Rhizobium R14. Bacterized Rhizobium R7, R10 and R14 increased by 193.61, 187.23, 159.57% respectively as compared to control plant.
