Abstract

Use of organic manures for crop productivity not only improve crop production but also improving soil physicochemical properties. It also reduces soil and water pollution by acting as chelating agent for inorganic nutrients. Keeping these things in view an experiment was carried out aiming the use of different organic manures for improving crop productivity and to select a potential organic manure that improve crop productivity compared to others. All the manures were applied at the same rate 5 tons ha^-1. The results revealed that all the wheat parameters were significantly affected by differences in nature of organic manures except days to emergence. Plots receiving Poultry manures has high Spikes m^-2 (274), Grains spike^-1 (60), more 1000 grain weight (42.287 g), high biological yield (11435 kg ha^-1) and high grain yield (3996 kg ha^-1). Similarly, Sheep manure had also great effect on wheat parameters such as higher emergence m^-2(103), Tillers m^-2 (308), plant height (104.50 cm), Grains spike^-1 (60) and similar 1000 grain weight compared to poultry manures (42.200). Cattle and Farmyard manure were also found better compared to legume residue but were found less important in improving wheat quality compared to poultry and sheep manure. Similarly, legume residues showed very poor performance in improving wheat quality compared to other organic manures. Wheat parameters were found better performed when poultry or sheep manures applied at the rate of 5 tons ha^-1. Therefore, it is recommended that application of sheep or poultry manures at the rate mentioned above improve wheat components under the agro-climatic conditions of Pakistan.
