Salinity causes disturbance in symbiotic performance of plant and increases susceptibility of plants to soil-borne pathogens. Endophytic bacteria which are associated with their host plants have a beneficial effect for many different plant species and are determinant of cross-tolerance to biotic and abiotic stresses in plants. To maintain the growth and development of crops in saline condition, plant growth promoting rhizobacteria (PGPR) were isolated, and detected their plant growth promoting (PGP) potential under salt stress was investigated. In this study, fifteen endophytic bacteria were isolated from aerial parts of the rice which were grown in different regions of coastal soils. It was concluded that isolates Ri 4 and Ri 12 exhibited higher IAA production, isolates Ri 4 and Ri 5 showed better solubilization in phosphorous, Ri 3 and Ri 4 showed better solubilization of potassium. The result of this study can be used for further investigation in enhancing crop production and maintaining soil health in coastal saline soil environment.
