A field experiment was carried out on impact of varied sowing dates on the research farm of the AICRP on linseed and mustard, College of Agriculture, Nagpur, during the 2023-24 growing season. Ten Indian mustard (Brassica juncea L.) genotypes (sub factor) were used in this study i.e. ACN-240, SKM-1626, ACN-226, ACN-244, ACN-250, ACN-255, T-9, ACN-237, PM-26 (check) and TAM 108-1 (check). These genotypes were sown on four different dates (main factor) i.e. 30th October (timely sown), 15th November (moderately late), 30th November (late), 15^th December (very late). Three replications in a factorial randomized block design (FRBD) were used to set up the experiment. Results revealed that, genotype ACN-237 outperformed other genotypes on October 30, November 15 and November 30 in terms of Morpho-physiological parameters including plant height, number of branches plant^-1, leaf area, leaf area index, crop growth rate and relative water content. For genotype ACN-237, the 30th October, 15th November and 30th November sowing dates had no significant percent reduction in yield and yield-attributable characteristics including number of siliquae plant^-1, test weight, seed yield plant^-1, seed yield plot^-1 and seed yield ha^-1. In Sowing dates, there is a significant yield reduction in very late sown condition (15th December) in comparison with timely sown (30th October) condition in yield and yield-attributable characteristics including number of siliquae plant^-1 (19.19%), test weight (21.68%), seed yield plant^-1 (29.05%), seed yield plot^-1 (40.00%) and seed yield ha^-1 (39.35%).
