Field studies were carried out during the winter season of 2012-13 and 2013-14 at research farm of Department of Agricultural Meteorology, CCSHAU, Hisar (Lat. 29°10'N, Log. 75°46'E and 215.2 m amsl) to compute the temperature based agrometeorological indices for Indian mustard (Brassica spp. L.) sown under different growing environments. The experiment was laid out in split plot with three growing environments imposed through different sowing dates in main plots and three varieties of mustard (RH 30, Laxmi and RH 0749) in subplots and replicated four times. The early sown crop (D1) had significantly higher agrometeorological indices (HU, PTU, HTU, Tp, Tn and TUE) values over the second (D2) and third date (D3). Among the varieties, RH 0749 performed better with respect to agrometeorological indices. The seed yield and biological yield were highly significantly co-related with the accumulated HU (0.912**, 0.973**), PTU (0.924**, 0938**), HTU (0.851**, 0.973**) Tp (0.797**, 0.748**) and Tn (0.805**, 0.769**) clearly suggesting thereby the significant effect of these indices on the mustard crop. These indices can therefore very well used as indicators of crop performance, once these relationships are quantified and tested.
