The PGP (plant growth promoting) rhizobacteria are root colonizing bacteria which exist in symbiotic relationship with plants. The plant microbe relationship is used to increase crop yield in form of bioinculants applied during cultivation. A study resulted in isolating 61 rhizobacteria from Allium cepa (Onion) root rhizosphere. The screening was carried out to explore multifunctional plant growth promotion traits like Phosphate and Zinc solubilization, Ammonia production, IAA production, HCN production, Siderophore production, and ACC deaminase activity in laboratory condition. The ACC deaminase enzyme activity of bacteria is exploited to relive stress on plants aiming to enhance yield. The multifunctional isolate B10 and V15 revealed maximum 6 out of 7 characters tested. The studies on gnotobiotic seed germination and root elongation assay showed significant increase in treated root length and % germination compare to equivalent control. The multifunctional PGPR isolates B10 and V15 may show potential as a bioinoculant for increasing crop yields of Onion.
