Potential of Indigenous Rhizobacteria and the Consortium for Promoting the Growth of Sorghum bicolor (L.)

Background: The present scenario of agriculture is dependent on chemical fertilizer, pesticides and artificial growth promoters etc. extensive uses these chemicals fertilizers affect soil it become less fertile. These problem requireaying an attention towards the use native biological agents for endorsement plant growth. Indigenous rhizobacteria are rhizospheric bacteria having ability to enhance yield crop along with bulk bacteria. Methods: In study selected area was North Maharashtra region in which mainly sorghum cultivated. Total 320 were screen PGP traits viz. IAA, GA, ACC deaminase production, phosphate, zinc, potassium solubilization. potential PGPR used seed germination pot assay. Result: highest IAA production 79.74 µg/mL GA producing isolate shows 227.27 µg/mL. quantitative analysis Phosphate reports 455 µgm/mL. Most isolates showed positivity all traits. From among isolates, 12 preparation consortium. Seed plate assay vigor index (820) by mixture both biostimulators. Similar results obtained during assay, 3320 combine treatment
