Gibberellic acid (GA3) considered as one of the important plant hormone in growth and development of plant. It has wide applications in agriculture area as well as in horticulture. Bacteria have symbiotic association with plant thus they utilize atmospheric nitrogen and help plant for growth .one of the important metabolite known as gibberellic acid synthesised by bacteria utilized by plant for their growth and development. This study aims at isolation of gibberelic acid producing bacteria and its characterization .Total 25 isolates were isolated from rhizospheric soil of various local plants such as Rice, sugarcane, jowari, mug bean from agricultural field of solapur area .these isolates were screened for gibberellic acid production in artificial nutrient media and analysed by spectrophotometric method. Among these isolates RR5 ( Rice Rizobacteria ) and SR2 (Sugar Rhizobacteria) produce gibberellic acid in high amount as compare to other isolates and thus used for further study. The filtrate was bio assayed on wheat plant and show significant growth after treatment with organic solution of rhizobacterial filtrate.
