Abstract: First date of sowing i.e. 5^th November 2014 (D₁) was significantly superior for most of the growth, seed yield and quality parameters as it showed percent increase of 35.04 in no. of siliquae/plant, 32.11 in no. of seeds per siliqua, 14.40 in seed yield q/ha, 2.58 in seed recovery, 9.64 in oil content, 5.78 in germination, 8.01 in seed vigour index-I and 10.12 in seed vigour index-II over second date of sowing i.e. 18^th November 2014. Treatment with T₇ (RNPKS ie. 60:40:40NPK + 40kgS + 25 kg /ha ZnSO4 + 5 kg/ha FeSO4) was found significantly effective for getting highest yield (19.73 q/ha), highest no. of secondary branches (14.75), germination (75.41%), shoot length (9.22cm) and root length (7.11cm) as well as for quality, having highest oil content (33.37%) vigour Index–I (1528.21) and vigour Index-II (11.34). Interaction of D₁xT₇ also exhibited significantly highest seed yield (21.30q/ha) and no. of secondary branches (17.25). Maximum seed yield and quality can be achieved by sowing of treated seed with carbendazim @ 2g./kg in first week of November with nutrient application of RNPKS i.e. 60:40:40 and 40 kg S + 25 kg ZnSO4 + 5kg FeSO4/ha.
