Sowing time and irrigation play an important role to ensure higher production. Delay in sowing affects the growth and development of crop. Studying the effect of irrigation scheduling and sowing dates can provide a knowledge for improving production in late sowing conditions. A field experiment was conducted during the rabi season of 2020-21 at Jawaharlal Nehru Krishi Vishwa Vidyalaya, Jabalpur, Madhya Pradesh to study the influence of irrigation scheduling on physiological growth parameters and yield of wheat under different sowing dates. The experiment comprised of 12 treatment combinations having three sowing dates, 3^rd December, 18^th December and 2^nd January in the main-plot and four Irrigation Water/ Cumulative Pan Evaporation (IW/CPE) based irrigation scheduling, viz. 1.0, 0.9, 0.8 and 0.7 in the sub-plot was analyzed in split-plot design with three replications. The findings of present investigation revealed that the physiological growth parameters and yield were higher in 3^rd December sown date. Among the irrigation scheduling, IW/CPE ratio 1.0 recorded significantly higher growth parameters and yield. The results of the present study conclude that adjusting sowing date with irrigation scheduling could assist in enhancing yield.
