Abstract

Nitrogen fixing and phosphate solubilizing microbes were isolated from legume nodules and rhizosphere region of legumes respectively. The distribution of phosphate-solubilizing microbes was more in the rhizosphere region. The solubilization efficiency of the microorganisms ranged from 46.67 to 75.00 % on the Pikovaskaya medium. The Symbiotic effectiveness of isolated Rhizobialisolates no 2 was 162.50 %. A novel Rhizoazophos consortium was prepared using the microbial inoculants isolated from Virudhunagar. The application of Rhizoazophos biofertilizer prepared with rice bran significantly increased the shoot and root dry matter, survived better and increased the number of nodules and dry matter production
