Abstract: Plant growth promoting rhizobacteria (PGPR) are beneficial bacteria that colonize plant roots and enhance plant growth by a wide variety of mechanisms. Isolates of PGPR designated as Pseudomonas aeruginosa strain (2CpS1) is taken as PGPR. Subsequently, a pot experiment was carried out at wire house of the Department of Horticulture, Institute of Agricultural Sciences, Banaras Hindu University, Varanasi with chickpea variety (JW-14), four treatments and three replications during rabi season 2011- 2012. Isolate of PGPR induced production of plant hormones (indole acetic acid), phosphate solubilization and ammonia production to enhanced plant growth. Isolate resulted in a significant increase in shoot length, root length and dry matter production of shoot and root of chickpea seedlings under salinity condition. Therefore, present study suggests that Pseudomonas aeruginosa strain (2CpS1) may be used as bio-fertilizers to enhance the growth and productivity of chickpea.
