The effects of seeding data, and N and P fertilizer on the agronomic characteristics of 2 rapeseed species (Brassica campestris L. and B. napus L.) were studied for a 6 yr period at 2 northwest Alberta locations. Seeding dates were established at weekly intervals from early May to mid-June. Two fertility levels were established; a control treatment in which no fertilizer was applied and a fertilizer treatment in which N and P were applied to meet the requirements of a 1680 kg .cntdot. ha-1 crop. Maximum yields were obtained most frequently with seeding periods of mid- to late May for B. campestris and mid-May for B. napus. Seeding data had little effect on plant density or seed quality. N and P fertilizer reduced plant densities but increased seed yield where nutrient deficiencies occurred.
