Abstract

Under semiarid climate, the higher soil pH and alkalinity reduce phosphorus (P) availability and thus crop productivity. The higher prices of P-fertilizers restrict small holders to apply the required P level to their field crops. Proper P management under semiarid climates is very essantail for increaase crop productivity of smallholders. An expriemnt was work out in 2013-15 to study the impact of P management on wheat total biomass and harvest index. The expriment was worked out at the University of Agriculture, Agronomy research farm. In experiment one, treatments were: four P levels (100, 80, 60 and 40 kg P ha-1), three levels of zinc (15, 10 and 5 kg Zn ha-1) and three timings of beneficial microbes (BM) timings of application (at sowing, 20 DAE and 40 DAE). It was concluded from the experiment one, that application of 80 kg P ha-1 + 15 kg Zn ha-1 along with BM at 20 DAE produced higher wheat biomass and harvest index. In experiment two, treatments were: four P-fertilizers sources (TSP, DAP, SSP, NP), four P levels (120, 90, 60, 0 kg P ha-1) and three varieties of wheat (Shahkar-2013, Pirsabak-2013, and Atta-Habib-2010). The results indicated that maximum biomass yield and harvest index was calculted with SSP application. Maximum biomass and harvest index was produced with 120 kg P ha-1 application to the soil. Among wheat varieties Pirsabak-2013 perform better than others by producing higher harvest index and biomass.
