Abstract:
A field experiment was conducted at Main Agricultural Research Station, University of Agricultural Sciences, Dharwad during kharif, 2016 to study the response of French bean to different source of irrigation water with graded levels of fertilizer on yield, water productivity and its economics. The study consisted of four different source of irrigation water ie., Domestic wastewater (DWW), Engineered constructed wetland treated wastewater (TWW), fresh water (FW) & Engineered constructed wetland treated wastewater altered with domestic wastewater (TWW-DWW) and five levels of fertilizer ie., no RDF, 25 %, 50 %, 75 % and 100 % RDF). Significantly higher yield (4261 kg/ha) of French bean was recorded with DWW irrigation as compared with other sources of irrigation. Application of 100 per cent and 75 per cent RDF resulted in higher yield of French bean (4240 kg/ha and 3965 kg/ha, respectively) over other fertilizer levels. Among the interaction effect, application of DWW with 100 per cent RDF recorded higher yield of French bean (5294 kg/ha) which was on par with DWW irrigation with 75 per cent RDF (4985 kg/ha). Higher water productivity (113.8 kg/ha.cm), net return (Rs. 87,084/ha) and net profit per cm of water used (Rs. 2,326/cm) was recorded with DWW irrigation as compared to other sources of irrigation. Similarly, application of 100 per cent RDF recorded higher water productivity (113.2 kg/ha.cm), net returns ((Rs. 83,854/ha) and net profit per cm of water used (Rs. 2,240/cm). However, it was on par with application of 75 per cent RDF. Interaction effect results indicated that application of DWW as source of irrigation with 75 per cent and 100 per cent RDF resulted in higher water productivity, net returns and net profit per cm of water used.
