Effect Of Conjunctive Use Of Water On Yield Components And Marketable Yield Of Radish Crop

Availability of irrigation water at reasonable cost is one of the most important factors for agricultural development. Conjunctive use of fresh and sewage water can successfully be adopted for cultivation. An experiment was laid out at the research plot of Allahabad Agricultural Institute-Deemed University, Allahabad, India in a randomized block design with three replications and four levels of sewage water i.e., 25%, 50%, 75% and 100% were applied to radish crop by blending with fresh water. It was observed that the higher level of sewage water significantly affected the vegetative yield of radish crop and provides maximum return at 100% sewage water. Plant height, root length, girth and yield of radish crop significantly increased with the increase of sewage content in the blended water. The blended water also increased the marketable yield of the radish crop. The fully sewage irrigated radish crop provided a net return of 3631.11US$/ha with a benefit cost ratio of 7.96.The study shows the marketable yield and water use efficiency of radish crop increase with an increase in sewage water ratio. It was also observed that the presence of fungi and bacteria were remarkably lower at 50% and 25% sewage water irrigated crops
