Abstract
Nitrogen (N) management practices for winter wheat including side banding at time of seeding, broadcasting in early December, and in April, were evaluated at nine locations in the province. Under the widely ranging climatic conditions that prevailed over the 1982-83 winter period and the 1982 growing season, side banding the N at time of seeding in the fall was equally as good as broadcasting the N in mid-April. Broadcast applications of urea made in early December resulted in disappointing yield increases. It is concluded from these experiments that where the nitrogen is side banded in the fall, spring wheat soil test guidelines for the humid areas of the province should be applicable to winter wheat grown in any soil zone.
Unequal distribution of crop residues was shown to seriously reduce yields of winter wheat, possibly as a result of the production of phytotoxic compounds.
