Environmental stress such as abiotic and biotic threatens crop productivity and food security worldwide. Biostimulant, particularly Plant Growth Promoting Bacteria (PGPB), offer a promising and sustainable approach to enhance plant resilience and growth under adverse conditions. These beneficial microbes colonize plant roots, promoting growth by various mechanisms, including nitrogen fixation, mineral solubilization, and the production of growth hormones. Furthermore, PGPB can Induce Systemic Resistance (ISR) in plants, making them more capable of fending off pathogens and pests. The application of PGPB in agriculture can significantly reduce the use of chemical fertilizers and pesticides, thereby minimizing environmental impact and promoting sustainable farming practices.
