Abstract:
Field studies were conducted at the IRS of Sam Higginbottom University of Agriculture, Technology and Sciences, Prayagraj (Allahabad, Uttar Pradesh, India) for two consecutive seasons; November 2020 to April 2021 and November 2021 to April 2022 to economic assessment of irrigation scheduling based on water limiting conditions) for enhancement of production and profitability of mustard crop (varunaT-59). Irrigation scheduling is based upon water limiting conditions. Five levels of water limiting conditions are I1 (irrigation at zero percent water stress of 60 mm designed depth of irrigation), I2 (irrigation at 20% water stress of 60 mm designed depth of irrigation), I3 (irrigation at 40% water stress of 60 mm as designed depth of irrigation), I4 (irrigation at 60% water stress of 60 mm as designed depth of irrigation) and I5 (Irrigation at 80% water stress of 60 mm as design depth of irrigation water. The experiment was conducted in Random block design with three replications. Maximum production and profitability recorded under treatment I3 at 40% water stress with 60 mm designed depth of irrigation). Maximum grain yield (2.25 t/ha) and straw yield (7.0 t/ha) recorded under treatment I3 at 40% water stress with 60 mm designed depth of irrigation. Maximum profit i.e. gross return (Rs/ha 114334.00), net return (Rs/ha. 76880.47) and (3.45) were calculated under treatment I3 (irrigation at 40% water stress of 60 mm as designed depth of irrigation).
