Field experiment with maize (Zea mays L.) was conducted to study the irrigation potential of treated (fish pond effluent) and untreated (raw sewage) domestic waste water. A split plot design with 3 different irrigation waters i.e. raw sewage, fish pond effluent and tap water, and 3 levels of nitrogen application i.e. 0, 50, 100 kg nitrogen per ha, was adopted. Maize can be successfully grown with treated and untreated domestic waste water. The plants irrigated with raw sewage showed pronounced vegetative growth. The dry matter production increased throughout the growth period in all treatments. The differences in grain and stover yields were significant for both, the 3 irrigation waters and 3 nitrogen levels. The nitrogen response to raw sewage can be better obtained at lower levels of fertilizer nitrogen application. Yields increased almost linearly with increasing consumptive use of water. The raw sewage was a better quality irrigation water since it contained valuable nitrogen and it required less water to produce unit weight of dry matter yield.
