Two isolates of Rhizobium were isolated from Babchi (Psorolea corylifolia) root nodules, which showed positive tests for catalase test, oxidase test, nitrate reduction test and starch hydrolysis while negative test for methyl red test, Voges-Proskauer test, urease test, gelatin lignification test, methylene blue test, urease test, gelatin liquification test, methylene blue test, lactose test, citrate utilization test and hydrogen sulphide production test. The isolate PCRI-1 and PCRI-2 exhibited a great variation in N fixation by of 24.35 mg/g and 20.70 mg/g of sucrose consumed, respectively. The amount of IAA produced by these isolates was 37.73 µg/ml and 32.40 µg/ml respectively. These isolates showed variation in PO4 solubilization efficiency in the range of 19.1 to 17.8 per cent, with solubilization zone of 6.2 mm and 4.2 mm, respectively. Its characterization and testing of plant growth promotion traits is the first attempt from the state of Maharashtra, from root nodules of Babchi.
