Abstract: Interactions between plants and microorganisms in the rhizosphere (rhizobacteria) affects crop yields likewise Plant growth promoting rhizobacteria (PGPR) influence the growth of plant by mean of various direct or indirect mechanisms. In current report the present investigations were undertaken to isolated and screen the PGPR from its natural growing zones of Wheat (Lok-1) rhizosphere. In present study, out of 50 different isolates, only 6 strains showed all the traits of plant growth promotion The isolated PGPR belong to gram positive generaand, were highly motile in nature. The study reviled that, all the isolates exhibited production of indole acetic acid, Gibberellic acid, indol-3 butyric acid, Siderophore, Ammonia, HCN andsolubilized inorganic phosphate. The investigated result supports possible utilization of the selected isolates in wheatVarity (Lok-1), growth promotion with respect to increase in agro productivity.
