Abstract
Groundnut root rot (Macrophomina phaseolina) and stem rot (Sclerotium rolfsii) are significant threats to yield in both rainfed and irrigated systems. This study aimed to isolate and evaluate plant growth-promoting rhizobacteria (PGPR) from groundnut soils in Tamil Nadu for their potential as biocontrol agents and growth enhancers. Fourteen PGPR strains were tested, with Pseudomonas putida GN1 (ON307464), Burkholderia cepacia KKM1 (OM908755) and Pseudomonas sp. K1 (ON408243) showing notable pathogen suppression. P. putida GN1 was the most effective, inhibiting M. phaseolina by 53.93% and S. rolfsii by 46.06%, while also boosting seed germination and seedling vigour. Additionally, P. putida GN1 improved drought tolerance by enhancing root growth characteristics. These results highlight P. putida GN1 as a promising biocontrol and plant growth-promoting agent for groundnut, particularly in drought-prone areas.
