A field experiment was conducted over two consecutive rabi seasons (2017-18 and2018-19) at three locations in Punjab (Ludhiana, Faridkot, and Ballowal Saukhri). The experiment followed a Factorial Split Plot Design with three dates of sowing (D1 – 25th October, D2 – 15th November, D3 – 5th December) and three wheat cultivars (V1- WH1105, V2 - UNNAT PBW 550, V3 - PBW 590) in the main plots, and two irrigationtreatments (I1: Recommended, I2: Recommended ± weather forecast based) in the subplots. Across both seasons, the crop sown on 15th November consistently exhibited the highest tiller count and dry matter at harvest. Grain yield was significantly higher for D2 compared to D3, and was comparable to D1 across all three locations. Among the cultivars, UNNAT PBW550 yielded significantly more than PBW 590. Among the locations Ballowal Saukhri had lowest grain yield. Analysis indicated non-significant differences in yield under different irrigation schedules across the three sowing dates
