ABSTRACT
Deficiency of Phosphorus (P) is a serious concern for agricultural productivity in more than 90% of Pakistan’s soils. In addition to P deficiency, high pH level and soil carbonate contents further limit the utilization of P by plants. This research was conducted during wheat cropping season of year 2010 and 2011 and it consisted of determination of the residual effect of six treatments (T0 = control without rock phosphate & farmyard manure, T1= rock phosphate @150 kg P2O5 per hectare, T2 = FYM @5 tons per hectare, T3 = RP @100 kg P2O5 per hectare+ FYM @5 tons per hectare, E0 = without effective microbes and E1= EM-Biozote @ 50 l ha-1) on yield parametrs of wheat crop planted after the harvest of rice. All yield parameters significantly increased by the treatments consisting of RP (100 kg) with FYM (5 t ha-1) and EM @ 50 l ha-1, which also enhanced the nutrient uptake of the crop. It can be concluded that accurate use of cheaper rock phosphate, farm yard manure and effective microbes proved as an alternative of costly fertilizers and sustaining the agricultural productivity. Residual effect of rock phosphate with additional use of farmyard manure with effective microorganisms would be a promising strategy for enhancing P use efficiency and productivity of wheat crop in eco friendly way.
