Iron is one of the most essential microelements for virtually all living cells but the availability of iron is limited due to very low solubility of the dominant ferric iron (Fe3+) in soil. Bacteria can produce low molecular weight iron chelating compound called siderophore. On account of that, an attempt was made in the present investigation to isolate potential siderophore producing bacteria from different places of Odisha and study their effect on different vegetables. A total of four siderophore producing bacteria was isolated from rhizospheric soil sample and amongst them BGBA-1 was found the most efficient siderophore (76.67% SU) producer. The potential isolates were further characterized for their different plant growth promoting activities like Indole acetic acid production (IAA), ammonia production, phosphate solubilisation, N2- fixation and HCN production. From biochemical and enzymatic characterization, it was found that these two bacteria belonged to the genus of Bacillus. The potential isolates were further tried with different vegetables to study the germination percentage, root length and shoot length by Roll towel method. A significant increase in various parameter of vegetables were observed which was also statistically significant.
