Governments, as well as growers, are working to reduce chemical uses in agricultural systems. In recent years, agricultural practices have resulted in an increase in the harmful chemical substances of rivers and underground water, as well as the salinization of soils. Solutions are therefore needed to maintain crop yield while also lowering chemical inputs such as chemical pesticides and fertilizers. One method for achieving the aforementioned desired practices is the employment of microorganisms in the soil that improve efficiency as well as nutrient uptake. The Intentional incorporation of soil microbes in crops is crucial to overcoming the challenge of boosting food production while significantly reducing pesticide usage, and environmental contamination and enhancing the productivity of natural resources. Microorganismsare capable of adapting and adjusting to the environment rather than surviving their surroundings. Plants are inhabited by microorganisms that have evolved to promote soil health through nutrient-recycling abilities. The plant growth promoting rhizobacteria (PGPR) have been investigated since the turn of the 20th century, and their physiological mode of action is now well established. PGPR have been recognized as essential growth-promoting traits with respect to their nutrient solubilizing, disease-resistant antagonistic ability, trigger and stimulating plant immunity, colonization, and adaptivity with rhizosphere and stress response. Together, these traits make them great in assisting living organisms formidably resistant and important for improving plant and soil health. The present review deals with the role of PGPR and their significance in encouraging the growth of plants for agriculture sustainability.
