Thirty eight rhizobacteria were isolated from the rhizosphere soil, purified and were selected on the basis of their ability to produce auxins (IAA-equivalents) in vitro. Eleven selected isolates were tested for yield promotion of potato (Solanum tuberosum) in a pot and field trial. In both the trials tuber yield, number of tubers and shoot + root weight was significantly promoted in response to inoculation. Tuber yield was increased upto 47.5% and 25.8% in pot and field trial, respectively in response to PGPR inoculation. Similarly number of tubers and shoot + root weight were enhanced upto 56.2% and 27.6% in pot trial and upto 27.1% and 23.1% in field trial, respectively. The isolates J2, J7 and J24 showed consistent superiority over the other isolates and these could be used as plant growth-promoting rhizobacteria.
