The field experiment was conducted during Rabi 2011-12 at SAREC, Kangra with five varieties (KBS-3, Neelam, RCC-4, Jayanti and ONK-1) and four dates of sowing (5th October, 15th October, 25th October and 4th November) in split plot design with three replications. The sowing beyond 5th October up to 4th November showed reduction in yield although differences were observed non-significant. Significant decrease in growth (plant height, dry matter accumulation, leaf area & leaves/plant), yield attributes (1000-seed weight, primary and secondary branches per plant, number of siliqua per plant, and seed weight per plant) was recorded with delayed sowing. Crop growth rate (CGR), relative growth rate (RGR) and net assimilation rate (NAR) decreased with delay in sowing. Delayed sowing recorded significant decrease in oil content but protein content increased significantly. Variety Neelam showed higher yield at 5th October sowing and yield decreased with delay in sowing while 4th November sowing was observed favourable for variety Jayanti. This infers that sowing of Neelam cannot be delayed, whereas Jayanti can be good option for late sowing. Due to higher disease susceptibility variety RCC-4 and KBS-3 gave significantly lower seed yield at 15th October sowing. Jayanti recorded significantly higher seed yield (1583.2 kg/ha) and oil yield (619.2 kg/ha) and more economic returns viz., gross returns (₹ 41039.5 ha-1), net returns (₹ 24191.4 ha-1) and benefit: cost ratio (1.4). |
