An experiment was conducted to evaluate the performance of wheat cultivar JAUW-672 conducted at Research Farm of Agronomy during Rabi season of 2019-20 and 2020-21 at Sher-e-Kashmir University of Sciences and Technology, Jammu consisted of twelve treatment combinations with two sowing dates, three fertility levels and two irrigation regimes replicated thrice under factorial randomized block design. The experimental results revealed that earlier sowing dates recorded highest pooled effective tillers/m2 (298.56), number of grains/ear (39.19), test weight (37.47) grain yield (41.98q/ha) and B: C ratio (2.17). Whereas, among fertility levels application of 125% RDF on soil test basis recorded significantly highest pooled effective tillers/m2 (305.81), number of grains/ear (40.14), test weight (38.30), grain yield (46.05) and B: C ratio (2.38) besides sustaining soil fertility. Whereas due to timely rainfall the irrigation treatments remained statistically at par. Thus to increase productivity and profitibality of wheat, the crop should be sown earlier with increased dosage of fertilisers but on soil test basis.
