Performance of brinjal crop with application of engineered constructed wetland treated wastewater in comparison to other sources of water was studied through field experiment conducted at University of Agricultural Sciences, Dharwad during kharif 2015. Experiment consisted of six different sources of water (domestic wastewater, treated wastewater, bore well water, conjunctive use of domestic wastewater and fresh water, fresh water and treated wastewater; domestic wastewater and treated wastewater). Sources of irrigation induced significant difference among the treatments. Significantly higher fruit weight per plant was recorded in the treatment irrigated with domestic wastewater (1251 g/plant) as compared to bore well water (874 g/plant) and treated wastewater (960 g/plant). Higher brinjal yield was recorded in the plot irrigated with domestic wastewater (17.43 t/ha). Conjunctive application of treated wastewater and domestic wastewater (17.37 t/ha); bore well water and domestic wastewater (16.96 t/ha); fresh water and treated wastewater (15.94 t/ha) resulted in higher and comparable yield with respect to the yield obtained in domestic wastewater irrigated treatment. Application of bore well water alone resulted in lower yield (14.53 t/ha). Domestic wastewater irrigation resulted in significantly higher water productivity (289.5 kg/ha-cm) as compared to fresh water (241.2 kg/ha-cm). Application of the domestic wastewater resulted in higher net returns and B:C ratio (` 2,18,355/ha and 2.68) followed by conjunctive use of engineered constructed wetland treated wastewater and domestic wastewater irrigation (` 2,17,035/ha and 2.67).
