This review examines how combining soil bacteria that help plants grow with tiny metal particles made by microbes can boost crop health, yields, and resilience — offering a more sustainable alternative to synthetic fertilizers and pesticides.
Microbiologically synthesized metal nanoparticles (including silver, zinc oxide, and titanium dioxide) can enhance plant growth and stress resistance when used in agriculture.
Plant growth-promoting rhizobacteria (PGPR) are increasingly recognized as effective biological agents for improving crop productivity and soil health without synthetic inputs.
The combination of PGPR and biogenic nanoparticles shows synergistic potential, meaning their combined effect is greater than either used alone, supporting more sustainable agricultural outcomes.
