abstract
An attempt was made to isolate and characterize indigenous phosphate solubilizing strains of Bacillus and Pseudomonas spp. from the rhizosphere of Aloe vera from different agro climatic locations of Himachal Pradesh and evaluate their growth promoting effect on Aloe vera. On the basis of in vitro plant growth promoting activities, total six isolates, three belonging to Bacillus spp. (AvNB-1, AvSB-2 and AvSB-5) and three belonging to Pseudomonas spp. (AvHP-1, AvSP-1 and AvSP-7) were selected and used in the pot experiment to study their effect on growth of Aloe vera, rhizosphere bacterial population and phosphorus concentration of soil. On the basis of the pot experiment, Pseudomonas spp. (AvHP-1) and Bacillus spp. (AvSB-1) were found to be the best among all the strains.
