An experiment was conducted to evaluate the use of sewage waste water as a source of irrigation and its impact on morphophysiology and yield of wheat (Triticum aestivum). The crop was grown with 50% WW, 100% WW and GW (Ground water) and with different doses of nitrogen (N0, N75 and N150 ie. at 0, 75 and 150 kg ha) along with uniform basal dose of phosphorus and potassium at 40 kg ha-1 each. The waste water contains higher amount of chloride, carbonate, bicarbonate, magnesium, calcium and total dissolved solids etc. as compared to GW. Soil showed no significant changes in electrical conductivity (EC), pH, calcium, magnesium, carbonate and bicarbonate etc. after receiving the wastewater irrigation. Significant increase was obtained in plant fresh wt., biomass plant−1, leaf characteristics, biological yield plant-1, chlorophyll a, chlorophyll b, total chlorophyll content, photosynthetic rate and photosynthetic water use efficiency with wastewater in comparison to ground water. Thus, it may be concluded that sewage waste water along with fertilizers may be used profitably for the cultivation of wheat (Triticum aestivum).
