Abstract

ABSTRACT: This field study evaluates the integrated impact of poultry manure (PM), rock phosphate (RP), composted rock phosphate (CRP) and single super phosphate (SSP) on the growth, yield, and phosphorus use efficiency (PUE) of winter wheat and their effect on postharvest soil characteristics. The seven treatments were as follows: T1 = control; T2 = SSP full; T3 = PM full; T4 = RP full; T5 = CRP full; T6 = 50% SSP + 50% CRP (50:50); T7 = 50% PM + 50% CRP (50:50) at a recommended P rate of 90 kg ha −1 . The combined treatment with PM + CRP produced the highest straw yield of 3582 kg ha −1, grain yield of 2226 kg ha −1, P uptake of 21.3 kg ha −1, and PUE of 18%. The postharvest soil organic carbon, total nitrogen and soil available phosphorus were sig-nificantly higher in integrated treatments.
