Synergistic role of microbiologically synthesized nanoparticles and PGPR in sustainable agriculture: a critical review.

In recent years, agriculture has undergone transformative innovations to enhance crop productivity, resilience, and nutritional value. With increasing concerns over food security, environmental degradation, and soil health, there is growing emphasis on sustainable agricultural practices. Among these strategies, the use of plant growth-promoting rhizobacteria (PGPR) have emerged as promising solutions.
