Native microorganisms as potent bioinoculants for plant growth promotion in shifting agriculture (Jhum) systems
Microorganisms native to shifting cultivation were isolated and screened for plant growth promotion (PGP) properties. The bacterial and fungal isolates that exhibed production of indole compounds, siderophores, and ammonia; phosphate solubilization; and catalase activity, were selected and tested fo...
