The salinity of the soil is becoming a major concern for the worlds food security. it is essential to create environmentally friendly sustainable techniques that boost saline soil productivity. Certain microorganisms have a dependency on salt as well as tolerance to it. Microbes that are resistant to salt may withstand ionic and osmotic stress. From very alkaline, saline, and sodic soils, many genera of salt-tolerant plant growth-promoting rhizobacteria (ST-PGPR) have been discovered. Numerous them are also known to help plants cope with a range of biotic and abiotic stressors. The possibility of using ST-PGPR to improve the productivity of plants under salt stress has been studied in the past several years, indicating that saline agro-ecosystems can be restored through its use. This review will focus on ST-PGPR and how they might boost saline agro-ecosystem production. Additionally, it sheds light on future research directions on the use of ST-PGPR for saline soil reclamation and PGPR-mediated mechanisms of salt tolerance in various crop plants.
