Characterization of Siderophore Producing Rhizobacteria and its Effect on Growth of Pea

Bacteria can produce low molecular weight iron chelating compound called siderophore. Siderophore are low molecular weight iron-binding ligands which can bind to ferric ion and make it available to the producer microorganism. On account of that, an attempt was made in the present investigation to isolate potential siderophore producing bacteria from different places of Kashmir and study their effect on pea crop. A total of ten siderophore producing bacteria was isolated from rhizospheric soil sample and amongst them PGP26 was found the most efficient siderophore (18.00). The potential isolates were further characterized for their different plant growth promoting activities like Indole acetic acid production (IAA), ammonia production, phosphate solubilization, and HCN production. The potential isolates were further tried with pea to study the germination percentage, root length and shoot length by Roll towel method.
