Background: Phosphorus has been considered as the key element as it is directly involved in most of the life processes including in plants. Soil contains both organic and inorganic forms of phosphorus. Phosphate solubilization is the important property of soil bacteria to develop them as plant growth promoting bacteria in the agricultural field. The present study report the phosphate solubilizing and plant growth promoting properties of selected actinobacteria isolated from rhizosphere soil.
Methods: Actinobacterial strains were isolated from rhizosphere soil and screened for in vitro phosphate solubilizing properties using agar plate method. The efficiency of phosphate solubilization and phosphatase activity of isolated actinobacterial strains were tested using Pikovskaya broth. 
Result: In the present study phosphate solubilization and phosphatase activity of isolated actinobacteria, Streptomyces sp. CTD-2 was comparatively higher in lab conditions. In pot trial experiment strain CTD-2 showed higher growth when compared to the control plant. The chlorophyll content of leaves in the experimental plants were found maximum with actinobacteria strain CTD-2 treated plant. Plant growth measurements such as root length, shoot length, leaf length, total plant growth measurements, quick yield production were also observed.
