Abstract: Microbes play important role in plant growth as it provides various substances((PGPR) required for plant to grow. Many organisms are responsible for that function depends on nature plant and organism. In present study exopolysaccharide producing organism were screened and checked how it contribute for plant growth. Exopolysaccharide substance producing microbes were isolated from soil sample of various region of valsad and vapi region. Total 14 exopolysaccharide producing microbes were screened positive for PGPR activity. These organisms were checked for various PGPR activity such as indole acetic acid production, ammonia production, zinc solubilization, siderophore production, HCN production, antagonistic test. Pot experiment was performed in which length of root and shoot were measured. Bacterial isolate I-25 gave maximum PGPR activity hence proved to be maximum contributor for plant growth which was proved by pot experiment. So, this organism was proved to be novel for plant growth.
