Field experiments were conducted to study the performance of wheat crop under acidulated rock phosphate (RP) during rabi season of 2009 - 2010 and 2010 - 2011. Pooled data indicated that RP + gypsum produced maximum shoot population, yield attributes, grain yield (49.2 q/ha), biological yield (120 q/ha), over other treatments and recorded highest benefit: cost ratio. Maximum nitrogen content in grain was recorded in SSP alone followed by RP + PM + PSB treatment. However, maximum total nitrogen uptake was recorded in RP + PM + PSB treatment. Maximum phosphorous content in grain was found in RP + gypsum and in straw in RP + SSP treatment. Maximum potassium content in grain was found in RP + pyrites and in straw in RP + FYM + PSB treatment, while maximum total phosphorus and potassium uptake was found in RP + gypsum treatment. RP + PSB recorded maximum available nitrogen after crop harvested while maximum available phosphorus and potassium was found in RP + gypsum. Rock phosphate acidulated with gypsum each 300 kg/ha found best in terms of recording grain yield, biological yield and benefit: cost ratio, and can be used as alternate source of phosphatic fertilizers.
