Plant growth promoting rhizobacteria are beneficial bacteria are one of the major groups of microbes that can be found in the rhizosphere, in association with roots which can enhance the growth of plant directly or indirectly. The present study aimed to isolate plant growth promoting and disease suppressing bacterial isolates native to rhizosphere soil and/or endophytic tissues of ginger plants from two different major growing location of each of Solan and Sirmour districts of H.P. (India). Nutrient agar, Jensen's medium, Pikovskaya's medium and soil extract medium are used for screening of microbial population associated with ginger and ginger roots, while for the population assessment, Pikovskaya's medium was used. The highest microbial count on ginger was at Sirmour (Narag), while the PSB +ve colonies (87.72) and % P solublizers to PVK count (79.00) associated with ginger root was highest at Solan (Kandaghat), Himachal Pradesh.
