Final yield of wheat crop is directly associated with the application of both organic and inorganic fertilizers and is considered to be a key factor in cereal-based cropping system. In order to explore the effect of organic and inorganic fertilizers the current study was conducted at Palatoo Research Farm, the University of Agriculture, Amir Muhammad Khan campus Mardan during 2015-2016. The experiment was carried out in randomized complete block design with 12 treatments. The treatments consisted of T₁=Control, T₂=urea (U), T₃ = Farmyard manure (FYM), T₄= Poultry manure (PM) T₅= Sheep manure (SM), T₆= FYM + U, T₇= PM + U, T8= SM + U, T9= FYM + PM + U, T10= FYM + SM + U, T₁₁= PM + SM + U, T₁₂= FYM + SM + PM + U. In order to apply 120 kg N, organic and inorganic sources were combined in different rations. Wheat cultivar Galaxy “2013” was sown in the month of Dec-2015 at the seed rate of 120 kg ha^-1. The results of the study indicated that Organic and inorganic amendments and their different combinations significantly affected all parameters. Sole application urea(U) performed better which improved tiller m^-2(267), leaf area index (2.40), days to maturity (142), grains spike^-1(53), thousand grains weight (37g), grain yield (2376 kg ha^-1). Likewise, higher number of tiller m^-2(283), grains spike^-1(56), leaf area index (2.62), thousand grain weight (38.8 g), grain yield (2471 kg ha^-1) with the combinations of organic and inorganic amendments applied in different ratios. In case of organic manures, poultry manure (PM) produced higher tillers m^-2(256), grains spike^-1 (48), leaf area index (2.25), thousand grains weight (35.9g), grain yield (2301 kg ha^-1) when applied alone. It is concluded that sole application of PM or integrated application of PM + U performed best among all organic and inorganic amendments used alone and in combinations, therefore it is recommended for obtaining higher grain yield of wheat under rainfed condition of Mardan.
