Plant growth promoting rhizobacteria from the rhizospheric soil and roots of capsicum plants in agro-climatic zone-III (High Hills Temperate Wet) of Himachal Pradesh were isolated. Out of 40 isolates, only two isolates (JHA6 and ROH14) possessing maximum of PGP traits were evaluated for their effect on production of capsicum. Seeds were treated with selected isolates and 100%, 80%, 60% recommended doses (RD) of chemical fertilizers (N and P), while non-inoculated treatment with 100% RD of NPK was control. Pot experiment was conducted under net house conditions, using completely randomized design, with three replications. Maximum shoot length (79.0 cm) and biomass (39.75 g) as well as root length (32.9 cm) and biomass (2.63 g), were recorded under combined application of 100% RD of chemical fertilizers with JHA6 isolate. Fruit yield was increased by 9.17% over control which was, statistically on a par with treatment with ROH14 isolate and 100% RD of NPK. The application of 80% RD of N and P plus either of the tested PGPR isolates was statistically on a par with control clearly saving about 20% of chemical fertilizers.
