Under late-sown conditions, heat stress results in poor development of wheat, which may be avoided by seed priming techniques. The purpose of this study was to assess the effectiveness of several seed priming methods for boosting wheat growth and yield when sown late. In this regard, from December 2019 to March 2020, a field investigation was carried out at the Agronomy Field Laboratory of Bangladesh Agricultural University. The experiment comprised three factors, Factor A: wheat variety namely, BARI Gom-27 and BARI Gom-33; Factor B: sowing dates such as 01 December 2019, 15 December 2019, and 30 December 2019; Factor C: Method of seed priming namely, control (no priming), priming with 20,000 ppm calcium chloride and priming with 20,000 ppm potassium chloride. With three replications, the experiment was set up using a split–split plot design. Research revealed that seed priming was generally effective in promoting plant growth, spikes number m−2, grains spike−1, thousand-grain weight, and grain yield. Both potassium chloride and calcium chloride performed significantly similar. As BARI Gom-33 is more resistant to heat stress, it outperformed BARI Gom-27 in terms of spike length and grains spike−1. However, BARI Gom-27 and BARI Gom-33 performed quite similarly and wheat yield decreased gradually with the delay of sowing due to temperature stress. A clear advantage of seed priming was found in increasing grain yield at all sowing dates. Therefore, it is recommended to sow wheat by 15 November following seed priming and in case of delay sowing seed priming is a must to mitigate the temperature stress to some extent.}, number={2}, publisher={Atatürk Üniversitesi}
