Abstract: In the present study, Twenty five Pseudomonas strains were isolate from rhizosphere of maize plant and twenty five Rhizobium strains were isolate from the nodules of Gram plant in 05 different sites at Dehradun (Uttarakhand). Both Pseudomonas and Rhizobium strains were characterised on the basis of Holt. et al., (1994). Plant growth activity of bacteria and interaction studies were done as per Deshwal et al. (2003). Seventeen Pseudomonas strains and fourteen Rhizobium strains produced Indole Acetic Acid (IAA), Siderophore, HCN, phosphatase enzyme of them, only three combinations of Pseudomonas and Rhizobium strains enhance plant growth activity in Peanut (Arachis hypogaea L.) as compared to individual strains
Key words: Arachis hypogaea, Pseudomonas, Rhizobium.
