An experiment was conducted during 2015 rabi season in a green house, Faculty of Agriculture, BCKV, Mohanpur, West Bengal to evaluate the influence of organic and inorganic amendments on phosphorus dynamics in relation to growth and yield of rice (cv. Shatabdi) in an Alfisol soil. Rhizosphere soil samples collected from pots during tillering, flowering and harvesting stages of rice were analyzed for available phosphorus. Six different treatments with and without phosphate solubilizing bacteria were tried in completely randomized design with 3 replications. Among the different treatments, Silicon through calcium silicate + Organic manure through FYM (T5) resulted in higher values of yield attributes, (no of tillers, panicle, and plant height) and grain yield and straw yield significantly. Phosphate solubilizing bacteria inoculation showed a significantly increase in the values of yield attributes of rice and gave higher grain yield than the uninoculated ones. Interaction between different treatment and PSB showed a significant effect on the available phosphorus in soil at different stages of rice growth and yield attributes.
