Phosphate solubilizing bacteria (PSB) helps in uptake of insoluble phosphate by plants. ‘Phosphate’ is one of the most essential growth promoting factor and plays a vital role in plant cellular enhancement processes like root elongation, proliferation and changes of root architecture due to its deficiency, seed development, and normal crop maturity. Therefore, the present study was targeted for isolation of potential PSBs from Dhapa agricultural soil samples and was assessed for the plant growth promoting traits. The assessments include indole acetic acid assay (IAA), ammonia, siderophore, and hydrogen cyanide (HCN) production and their effects on growth and uptake of phosphorous by chilli plants. The estimation of growth of the chilli plants were observed with a pot experiment. According to the study the IAA production was 2.9, 4.9, 1.92, and 3.17 ?g/ml for the isolated organisms PSB AR1, PSB AR2, PSB AR3 and PSB AR4 respectively. Amount of phosphate solubilized were 70, 60, 67.6 and 54% by PSB AR1, PSB AR2, PSB AR3 and PSB AR4 respectively.
