tailieunhanh - Response of treated and untreated domestic waste water irrigation on yield, water productivity and economics of cluster bean

A field experiment was conducted to study the response of Engineered constructed wetland treated and untreated domestic wastewater irrigation on vegetative growth, yield, water productivity of cluster bean and soil properties at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during Rabi/Summer 2015-16. The study consisted of six different sources of irrigation water ., Domestic wastewater, Engineered constructed wetland (ECWL) treated wastewater, fresh water, fresh water alternated with domestic wastewater, fresh water alternated with ECWL treated wastewater and ECWL treated wastewater alternated with domestic wastewater. Results indicated that higher yield of cluster bean (8874 kg/ ha) was recorded in domestic waste water as compared to fresh water (5145 kg/ha). However, it was on par with treated waste water alternated with domestic waste water (7703 kg/ha). Higher water productivity was achieved with domestic waste water ( kg/ha-cm) followed by treated waste water alternated with domestic waste water ( kg/ha-cm). Significantly higher net returns (Rs 1,34,440/ha) and B:C ratio () were obtained with application of domestic waste water as compared with all other treatments except treated waste water alternated with domestic waste water ( and , respectively). The highest and lowest net profit of Rs 2485 and 1106 were obtained per cm use of water in case of domestic waste water and fresh water irrigation, respectively. However higher net profit of Rs 2052 per cm water used was also recorded in treated waste water alternated with domestic waste water. Insignificant difference with respect to soil pH and electrical conductivity was recorded under different sources of irrigation at 0-20cm and 20-40 cm soil depth. Significant difference in available nitrogen content was observed at both the soil depths due to different source of the irrigation water. | Response of treated and untreated domestic waste water irrigation on yield, water productivity and economics of cluster bean
