Field studies were carried out during the winter season at the Research Farm of the College of Forestry, SHUATS, Prayagraj (25°45'N, 81°84'E, and 98.2 m amsl) during rabi season 2022. to compute the temperature-based agrometeorological indices for Indian mustard (Brassica spp. L.) sown under different growing environments. The experiment was laid out in the FRBD method with three different dates of sowing 17 Oct, 03 Nov, and 17 Nov., and four varieties of mustard (Jhalak, Sriram, Kalasona, and Ratna). The third date of sowing crop (D3) had significantly higher agrometeorological indices (HU, PTU, and HTU,) values over the first (D1) and third date (D3). Among the varieties, Jhalak performed better concerning agrometeorological indices. HU (1886.2), HTU (6569.08), and PTU (11747.87) suggest there by a significant effect of these indices on the mustard crop. Once these correlations are measured and evaluated, these indices can consequently be used effectively as crop performance indicators.
