Effect of Temporal and Varietal Variability on Growth and Developmental Parameters of Brown Sarson (Brassica rapa L. Var. Oleifera) Under Temperate Kashmir Condition

A field experiment was conducted at KVK, Gandarbal, Shuhama, Sher-e-Kashmir University of Agricultural Sciences and Technology of Kashmir during rabi season 2011-12 to study the effect of temporal and varietal variability on growth and developmental parameters of brown sarson (Brassica rapa L. var. Oleifera) in split plot design, consisted of three dates of sowing in main plot and four varieties in sub plot replicated four times. The results revealed significant increase in growth parameters, like plant height, dry matter accumulation and partitioning, leaf area with 1st October sowing as compared to 15th and 30th October sowing. Among varieties, P-3 revealed significant increase in growth parameters than Shalimar Brown Sarson-1, Gulchein and KOS-1. Maximum seed yield i.e. 17.72q ha-1, stover yield (56.73 q/ha)and oil yield (635.07 kg/ha)was obtained with 1st October sowing, than 15th October and 30th October sowing. However, in respect of varieties P-3 recorded higher yields of seed, stover and oil.
