Description M.Sc.
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).
