Abstract
degradation. This study's goal was to look at how various organic additions affected soil characteristics, crop development, and water-fertilizer productivity in dry environments. Two different crop experiments of same treatments were conducted at Agriculture Research Farm, The University of Agriculture Peshawar, during summer and winter season in 2018-2019. First experiment on effect of different amount of organic and inorganic fertilizer on yield of maize and soil properties” was carried out during kharif season in 2018 and 2019. The experiment was consist of two factors i.e., factor A was of two different maize varieties i.e. (Azam, CS220) and factor B was fertilizer amendments (control, ½ NPK, Full NPK, Legume residues @ 10 ton ha-1 , Biochar @ 10 ton ha-1, Humic Acid @ 5 kg ha-1,Legume residues @ 10 ton ha-1+ ½ NPK, Biochar @ 10 ton ha-1+ ½ NPK, Humic Acid @ 5 kg ha-1+ ½ NPK,5 ton ha-1 Legume residues+ 5 kg ha-1Humic Acid ½ NPK, 2.5 ton ha-1 residues + 5 tons ha-1Biochar + ½ NPK, 5 tons ha-1Biochar + 2.5 kg ha-1Humic Acid + ½ NPK) which was applied before two weeks. The varieties were allotted to main plots and all the organic amendments were assigned to sub plots. Experiment II carry over effect of organic amendments on wheat crop same layout of experiment no 1 was used for this experiment. Residual effect of the following treatments (applied to maize crop) was studied using one variety of wheat. In this experiment carry over effect of the previous experiment was studied. Results of the (Experiment I) exhibited that certain parameter were considerably influenced by the application of different rates of fertilizers applied from the organic
