Abstract

In the context of sustainable agriculture, plant growth-promoting bacteria (PGPB) are key microbial biostimulants. These beneficial microorganisms enhance nutrient uptake, strengthen plant defence mechanisms, and improve tolerance to abiotic stresses, contributing to reduced reliance on chemical inp...
