Abstract: The field trial was carried out to investigate the effect of transplanting dates on different heat indices and productivity of Indian mustard (Brassica juncea L.). Three Indian mustard cultivars viz., NRCHB 101, Kesari Gold, and Kesari 5111) were transplanted from November to December viz., 3rd November, 14th November, 25th November and 6th December. The field data pointed out that the number of days needed to reach various phenological phases reduced with late in transplanting. Maximum growth, productivity as well as the highest value of heat summation indices like GDD, HTU, PTI and HUE at various phenological stages were recorded with Kesari Gold cultivar and the mustard crop transplanted on 3rd November. SPAD index of Kesari Gold variety was significantly greater than of remaining varieties. Mustard cultivar Kesari Gold cultivar recoded highest yield (1107 Kg ha-1) whereas the 3rd November transplanted mustard recorded maximum seed yield (1361 Kg ha-1).
