A field experiment was conducted during the winter (rabr) seasons of 1999 2000 and 2000 2001 to study the response of lndian mustard [Brassica juncea (L.) Czernj. Cosson] to sowing date and row spacing. Sowing on 25 September and 5 October recorded significantly higher number of blanches, seedslsiliquae, siliquaelplant, 1,000 seed weight and seed yield than that on 15 October, 25 October and 4 November. Seed yield decreased progressively with delay in planting. However, seed yield was significantly influenced by different row spacing. Significantly higher seed yieldlha was recorded with 30 and 45 cm row spacing than 60 cm row spacing. A row spacing of 45 cm was found suitable for crop sown on 25 September and 5 October, while 30 cm was optimum for lndian mustard sown beyond 5 October. Oil content (%) was significantly influenced by sowing date but remained unaffected due to variation in row spacing.References
