Use of synthetic fertilizers have some problem to farmer due to short residual effect and high cost. Since the farmers used organic manure due to long residual effect but the nutritional requirement is not fulfilling during one season of crops. So, using of organic manure and with combination of inorganic manure not only fulfill the nutrition requirement of the plants but also improve the fertility status of soil. Therefore, a field experiment was carried out in Agriculture Research Station Swabi KPK, Pakistan during 2015-16. Zinc (ZnSO4) and organic manure (farmyard manure+poultry manure) were used as treatments combination T1=Control, T2=Zinc 10 kg ha-1, T3=FYM 20 ton ha-1, T4=PM 5 ton ha-1, T5=Zinc+FYM, T6=Zinc+PM, T7=FYM+PM, T8+Zinc+FYM+PM. NP and K were applied as basal dose @ 120:90:60 kg ha-1. Experimental results showed that all the treatment were significantly (p ≤ 0.05) different. The maximum plant height (86 cm), maximum biological yield (6842 kg ha-1), maximum grain yield (2827 kg ha-1), higher soil N (0.40%), maximum soil P (7.6 mg/kg), maximum soil K (91 mg/kg) and maximum soil organic matter content (1.0%) from the plot having T8+Zinc+FYM+PM. It is concluded from these result the combines used of zinc, farmyard manure and poultry manure produce higher yield and yield parameters of wheat and also enhance the fertility status of soil.
