چکیده
mineral and organic N sources (farmyard manure) on maize yield, N uptake and soil fertility was assisted in the field experiment carriedout on silty clay loam soil at new developmental farm of the university of agriculture, Peshawar Pakistanduring 2014. Combined dose of N provided from all sources was applied @150 kg ha-1. There were four replications and 6 treatmentsi.e., (T1) control, (T2) 150 kg N ha-1 from mineral source, (T3) 150 kg ha-1 from FYM, (T4) 25% FYM + 75% mineral N, (T5) 50% FYM + 50% N and (T6) 75% FYM + 25% mineral N. Maize variety (Azam) was sown in RCB design. Data on plant height, grain yield and stover yield were recorded in maize. Samples of grain and stover were analyzed for total N to determine its uptake by the crop. Results indicated that greatest plant height of 221.85 cm, maximum grain yield of 2046.12 kg ha-1 and straw yield of 7004.73kg ha-1 were obtained from treatment where 25% N was applied from farm yard manure and 75% from mineral fertilizer.Agronomic efficiency and nitrogen use efficiency were also found higher in the treatmentwhere 25% N were applied from farm yard manure and 75% from mineral fertilizer. Soil total N, organic matter and available P were significantly affected by the organic source and there integration with mineral N source. It was concluded that combination of organic and mineral N sources in ratio 25:75 are the best combination to achieve sustainable yield and soil fertility.
