Yield response factor and water footprint of mustard crop

A two-year (2020 to 2022) research conducted at Prayagraj (Uttar Pradesh, India) in IRS farm of Sam Higginbottom University of Agriculture, Technology and Science to assess the yield response factor, water use efficiency, Water footprint and economics of mustard (Varuna T-59) as influenced by varying approaches of irrigation scheduling. There are three approaches of irrigation scheduling i.e., the soil-water limiting condition, the climatological method and residual method of energy balance were considered. The experiment was plotted in random block design. This research work included 15 treatments with three replications. Under soil-water-limited conditions, irrigation volume is lowered by 20%, 40%, 60%, and 80% of the design depth of irrigation (60 mm) in the second, third, fourth and fifth treatments, respectively. However, in the first treatment, full irrigation depth is provided without any stress.
