A field experiment was conducted at Agricultural Research Station, Mugad, University of Agricultural Sciences, Dharwad, during the Kharif season of 1998-99 to study the effect of integrated use of rockphosphate with organics, pyrites and phosphorus solubilizing bacteria (Pseudomonas striata) as a source of phosphorus on the growth and yield of upland paddy. The test crop used was Paddy (variety-Amrut). The soil of the experimental site is clay loam. The soil reaction is acidic to neutral and salt content is low. Application of both organic manures with or without P solubilizer increased the drymatter and leaf area at all the stages of crop growth. DAP+FYM gave maximum grain yield of 32.25 q ha-1 which was significantly superior over mussoorie rockphosphate alone (28.96 q ha-1) and it amount to 11.4 per cent increase in grain yield of paddy over MRP, which was on par with MRP+FYM+PSB and MRP+FYM+PSB.
