Crop Production Research Priorities

Current research priorities for canola crop production

Every year, the Canola Council’s crop production and innovation team identifies the research areas with the most potential to increase yields and improve the sustainability and competitiveness of Canadian canola. These priorities are set through consultation with expert steering groups, the canola value chain and the annual Canola Week.

For more information about these priorities, contact the agronomy specialist listed under each heading.
