Role of plant growth promoting Rhizobacteria (PGPR) as a plant growth enhancer for sustainable agriculture: A Review
The rhizosphere of a plant is home to helpful microorganisms called plant growth promoting rhizobacteria (PGPR), which play a crucial role in promoting plant growth and development. The significance of PGPR for long-term agricultural viability is outlined in this review. Plant growth processes such as nitrogen fixation, phosphate solubilization, and hormone secretion are discussed. Increased plant tolerance to biotic and abiotic stress, reduced use of chemical fertilizers and pesticides, and enhanced nutrient availability, soil fertility, and absorption are all mentioned as potential benefits of PGPR. PGPR has multiple ecological and practical functions in the soil’s rhizosphere.
