Application of organic manures and its integration with chemical fertilizers could be effective in order to manage nitrogen for sustainable production of maize (Zea mays L.). Therefore, a field study was performed at Agronomic Research Area, University of Agriculture, Faisalabad, Pakistan to evaluate the different nitrogen sources for sustainable production of autumn maize. Poultry manure (PM) compost, press-mud (PrM) compost and urea were used as nitrogen sources. The study comprised of two experiments which was carried out during 2011 and 2012. In experiment-I treatments were control, 2 t ha -1 PM compost, 4 t ha -1 PM compost, 6 t ha -1 PM compost, 8 t ha -1 PM compost, 10 t ha -1 PM compost, 2 t ha -1 PrM compost, 4 t ha -1 PrM compost, 6 t ha -1 PrM compost, 8 t ha -1 PrM compost and 10 t ha -1 PrM compost. However, in experiment-II treatments were control, 100% N from PM compost, 75% N from PM compost + 25% N from urea, 50% N from PM compost + 50% N from urea, 25% N from PM compost + 75% N from urea, 100% N from PrM compost, 75% N from PrM compost + 25% N from urea, 50% N from PrM compost + 50% N from urea, 25% N from PrM compost + 75% N from urea and 100% N from urea. The results of experiment-I showed that crop growth rate, 1000-grain weight, biological yield, grain yield, grain protein and soil inorganic N, organic matter and water holding capacity were recorded maximum with the application of 10 t ha -1 PM compost compared to unfertilized control. Results of HYDRUS-2D model showed that maximum inorganic N was predicted in soils amended with 10 t ha -1 PM compost. However, 10 t ha -1 PM compost also gave maximum gross and net income and benefit cost ratio. The results of experiment-II showed that application of 25% N from PM compost + 75% N from urea gave maximum crop growth rate, 1000-grain weight, biological yield, grain yield, grain protein and soil inorganic N. The maximum soil organic matter and water holding capacity were attained where 100% N from PM compost was applied. However, HYDRUS-2D model predicted maximum soil inorganic N where 25% N from PM compost + 75% N from urea was applied. Moreover, economic analysis depicted that maximum gross and net income and benefit cost ratio were attained due to incorporation of 25% N from PM compost + 75% N from urea. This study suggested that 10 t ha -1 PM compost and 25% N from PM compost + 75% N from urea could be utilized successfully in agro-climatic conditions of Faisalabad, Pakistan for sustainable production of maize.
