Effect of Sulfur and Nitrogen application on springcanola production grown under a cool climate.

Canola (Brassica napus L.) production is important in Western Canada. However, in the province of Quebec (Canada), only a small area of spring canola is seeded each year. It is well known that sulfur fertilization improve grain yields of canola in Western Canada. However, there is no data on the effect of sulfur application on canola production in Quebec. The objective of this study was to determine the effect of sulfur and nitrogen on the productivity of canola in a northern agricultural area. Three sulfur rates (0, 20 and 40 kg ha-1) and three nitrogen rates (50, 100 and 200 kg ha-1) were evaluated during three years (2012 - 2014). Grain yields increased with sulfur application during the three years. The effects of sulfur were greater with high nitrogen applications. The results suggest that spring canola grown under cool conditions should be fertilized with sulfur where sulfur deficiency has been identified previously.
