Rhizosphere microorganisms play a crucial role in enhancing plant health by improving nutrient availability and inducing plant defense mechanisms. These microorganisms, including bacteria, fungi, and other microbes, contribute to soil fertility and plant growth by converting organic and inorganic substances into available nutrients. They also help in suppressing plant pathogens by secreting inhibitory chemicals and boosting plant immunity. This review highlights the importance of rhizosphere microorganisms in sustainable agriculture as biofertilizers and biopesticides. The rhizosphere is a dynamic zone where microbial interactions influence nutrient cycling, plant growth, and disease resistance. Microorganisms in the rhizosphere can enhance plant nutrient acquisition, stress tolerance, and resistance to biotic and abiotic stresses. They achieve this through various mechanisms, including the production of phytohormones, solubilization of phosphorus and potassium, and the synthesis of antimicrobial compounds. The role of rhizosphere microorganisms in soil nutrient availability and plant defense is essential for sustainable agriculture. Advances in microbiome research and omics technologies have provided new insights into the complex interactions between plants and their associated microorganisms. These technologies have enabled the study of microbial communities and their interactions within various ecosystems, leading to a better understanding of the role of rhizosphere microorganisms in plant health and soil fertility. The findings of this review emphasize the potential of rhizosphere microorganisms as a sustainable solution for improving agricultural productivity and reducing the reliance on synthetic fertilizers and pesticides.Rhizosphere microorganisms play a crucial role in enhancing plant health by improving nutrient availability and inducing plant defense mechanisms.
