Field experiments were conducted during 2001-02 and 2003-04 to study the effect of crop residue incorporation on the relative efficiency of diammonium phosphate and Mussoorie rock phosphate. The result indicate that phosphorus application significantly increased plant height from 78-81 to 81-84 cm, number of grains from 56-58 to 5765, 1000 grain weight from 33-34 to 234-39 g grain yield 4.1-4.5 to 4.4-6.2 tonnes/ha gross profit from Rs 28014-31657 to Rs. 29528-43121/ha and net profit from Rs. 7086 -10729 to Rs 8603-20908/ha. The response was limited to 40 kg P2O5 either as diammonium phosphate or Missoorie rock phosphate, however the economic optimum dose of Mussoorie rock phosphate was 53-79% higher than that a dimmonium phosphate but prouced almost similar yield (4.6-6.1 tonnes/ha) at their economic optimum dose. Agronomic efficiency and response and economic returns at economic optimum dose was higher with diammonium phosphate than Mussoorie rock phosphate. Residue incorporation had no significant effect on growth, yield attributes, yield and gross and net return of wheat but significantly increased the efficiency of both diammonium phosphate and Mussoorie rock phosphate. Thus a combination of Mussoorie rock phosphate + phosphate-solubilizing bacteria + crop residue incorporation hold a great promise as a P fertilizer in wheat for its increased productivity under north Indian condition.
