The bacteria that colonize the plant's rhizosphere are known as PGPR. The rhizospheric region is the area under the ground surface that is linked with plant roots. PGPR bacteria are free-living bacteria that colonize plant roots and have positive impacts on plant growth. The objectives of this paper were to isolate and identify the most powerful PGPR, as well as to assess their efficacy in terms of P-solubilization, HCN generation, and lytic enzyme activity (protease). A total of 11 bacterial isolates were identified in the Hamirpur district of Himachal Pradesh. All isolates were tested for a variety of plant growth-promoting characteristics, including phosphate solubility, HCN production and protease production. On PVK agar, 8 of the 11 isolates tested positive for P-solubilization in the 5-20 mm zone. One bacterial isolate exhibited positive hydrogen cyanide activity in the event of HCN generation. In the case of lytic enzyme activity, 7 bacterial isolates were positive for protease production.
