Abstract: In recent decades world population is increasing rapidly and food demand is a global upcoming conundrum. Chemical fertilizers are using forcibly to execute food demand it causes negative impact on soil health and environment and ultimately to human being. In this view, present study counsel promising approach to apply plant growth promoting rhizobacteria as an alternative to chemical fertilizers. Furthermore, total ten rhizospheric bacterial isolates were selected on the basis of siderophore production potential and zinc solubilization efficiency. The biochemical characteristics of the isolates confirmed their abilities to show extracellular enzymatic activity for urease, cellulase, catalase, lipase, casienase, gelatinase and amylase enzymes. Bacterial isolates also exhibited other plant growth promoting traits such as phosphate solubilization, indole acetic acid, ammonia, hydrogen cyanide and exopolysaccharide production. Afterwards, on the basis of plant growth promoting traits best six potential bacterial isolates were further evaluated for their plant growth promotory properties through seed vigour assay with green gram (Vigna radiata var. sweta). Obtained results confirmed significant bacterial influence on seed germination and other contributing characters. Among all, bacterial isolates WRPA 4 and WRPA 13 showed better plant growth promotion and could be used as premier bioinoculant to enhance crop yield and productivity by maintaining sustainable ecosystem.
