The present review describes the status of rhizosphere of agricultural plants where microbial community play important role by interacting with each other and also with the plants. Plant roots release various substances which provide suitable environment for the colonization of microorganisms around rhizosphere. Beneficial and harmful microorganisms for the growth of plants effect on the growth of the plants has been critically analysed whereas this review gives more emphasis of plant growth promoting rhizobacteria and benefit achieved to plants. N2 fixation, IAA production, P solubilisation, siderophore production and ACC deaminase activity by the rhizobacteria provide better conditions for the plants growth; therefore, these bacteria are popularly known as plant growth promoting bacteria (PGPR).
