英文摘要:
Pakistan is ranked seventh biggest country where climate change has imparted drastic impacts on crops productivity and profitability along with seriously disturbing the agro-ecological systems. Environmental pollution caused by chemical fertilizers along with their high prices which deplete economic turn-outs necessitates the utilization of organic materials for boosting the profitability of rainfed crops. A field trial was executed to investigate the response of maize to organic manures applied solely and conjunction with reduced doses of chemical fertilizers. The field trial was comprised of three nutrient sources including urea nitrogen, poultry manure, compost manure applied solely and in conjunction with each other. The productivity and profitability of maize under coherent fertilization regimes were taken as response variables. The research findings indicated that urea nitrogen remained superior to solo and co-application organic manures as far as grain yield of maize was concerned. The highest crop value was generated by urea nitrogen (US$2375) and it was followed by poultry manure applied in combination with urea nitrogen (US$2365). The coherent application of urea nitrogen and poultry manure gave the maximum net returns (US$2265), incremental income (US$513) and value-cost ratio (5.13), while among fertilization treatments, poultry manure and compost applied coherently generated the minimum net returns ($1765) and incremental income (US$31). Thus, coherently applied urea nitrogen and poultry manure is inferred as the most profitable fertilization regime under rainfed conditions.
