Abstract: A two-year (2020–2022) studied conducted entitled Under climatological method to develop empirical model for the irrigation level and benefit-cost ratio of mustard crops at Sam Higginbottom University of Agriculture, Technology and Science's IRS farm in Prayagraj, Uttar Pradesh, India. Under this research, Scheduling of irrigation based on climatological method. As a crop, mustard crop of verity Varuna (T-59) considered. Plotting the experiment using a random block design. This research work included 5 treatments with three replications. Under the climatological approach, irrigation is scheduled at five values of IW/CPE ratio i.e. 1.75 IW/CPE ratio (T1), 1.5 IW/CPE ratio (T2), 1 IW/CPE ratio (T3), 0.75 IW/CPE ratio (T4), and 0.5 IW/CPE ratio (T5). Design depth of irrigation (60 mm) calculated on the basis of total available water (TAW) by using field capacity, permeant wilting point of soil and root zone depth of the crop. Under climatological method, the benefit-cost ratio of the percentage of irrigation depth showed a satisfactory connection (R2 = 0.863). During the first trial (2020-2021) and second experiment (2021-22), the total seasonal water supplied ranged between 120 mm to 360 mm and the average yield fluctuates between 1.03 and 2.2 t/ha. A strong correlation between yield and irrigation level was shown in Fig. 1. (R2 = 0.768). Mustard crop is very diplomatic regarding irrigation level and moister stress. Treatments I4 and I5 have relatively low yields and shallow irrigation depths, respectively, because mustard is extremely sensitive to water depth or moisture stress, the yield is much lower under treatments I4 and I5 due to a lack of moisture.
