A field experiment was conducted to study the performance of wheat crop under acidulated rock phosphate (RP) during rabi season 2009-2010 The experiment was laid out in randomized block design with A total of ten treatments viz., single super phosphate (SSP) alone, RP alone, RP + gypsum, RP + SSP, RP + PSB, RP + FYM, RP + FYM + PSB, RP + pressmud (PM) , RP + PM + PSB and RP + pyrites and crop wheat var. PBW-550 were selected. Crop yield differed significantly due to different treatments. RP + gypsum produced maximum grain yield (49.2 q ha-1), biological yield (120 q ha-1), plant height, shoot population, dry matter accumulation and yield attributes viz., spike length, number of fertile spikelets per spike and number of grain per spike, over other treatments. Rock phosphate acidulated with gypsum, each 300 kg ha-1 found best in terms of recording grain, straw and biological yield and hence, can be use as alternate source of phosphatic fertilizer.
