Abstract
A study was carried out in calcareous soil (low in ABDTPA extractable phosphorus and zinc) to evaluate the effect of zinc fortified locally developed single super phosphate fertilizers on maize grown in summer 2016. Zinc fortified fertilizers were prepared in laboratory of soil science department, University of Agriculture Peshawar, Pakistan. Treatments consisted of mixing two levels of zinc 5 and 10 kg ha-1 with SSP during its formulation by three methods of fortification coating, blending and reaction along with separate application and no application of zinc or a control treatment. Results showed the two levels of zinc mixed by different methods with SSP significantly influenced various appraised parameters of maize crop variety. With varying zinc level and fortification methods thousand grain weights, biomass yield and zinc concentration in leaves and grain were influenced significantly. Zinc at the rate of 10 kg ha-1 fortified with SSP through coating method produced maximum yield and yield components. Zn concentrations were higher in grains than leaves. It was concluded form the study that zinc (at the rate of 10 kg ha-1) mixed with phosphate fertilizer by coating produced highest maize grain yield and this method can be recommended for calcareous soil conditions of Peshawar.
