Diverse crop rotations reduce soil-borne disease pressure

Science Edition 2015—Key practice: Following a diverse rotation reduces soil pathogen populations and disease pressure. However, crop rotation should only be one part of your integrated approach to disease management. Project title, Lead researcher: “Effect of crop rotation on canola seedling blight and soil pathogen population dynamics,” 2006-07, Sheau-Fang Hwang, Alberta Agriculture and Forestry Grower organization funder:...

Target seven to 10 plants per square foot

Science Edition 2014—Key practice: Target a population of at least seven plants per square foot to maintain yield potential for canola. This target will allow for some plant mortality due to post- seeding stresses without dropping below the minimum five plants per square foot required for canola yield potential. Key research: Leeson, Julia, Agriculture and Agri-Food Canada...

Rotate crops for blackleg and clubroot management

Science Edition 2014—Key practice: Increasing the number of years between canola crops in the rotation reduces incidence and severity of blackleg and clubroot in fields. Key research: Kutcher, H.R., University of Saskatchewan, et al. “Blackleg Disease of Canola Mitigated by Resistant Cultivars and Four-Year Crop Rotations in Western Canada.” Canadian Journal of Plant Pathology (2013).

Harvest prep starts in the spring

Studies have found that lower harvest losses in canola are associated with higher yield potential, especially when straight combining. This could be attributed to the additional strategies high-yielding growers carry out earlier in the season, such as seeding early, early weed control and frequent field scouting.
Science Edition 2014—Key practice: Reducing harvest losses starts with strong crop establishment, adequate fertilization, early weed control and frequent scouting. Key research: Liu, C., Agriculture and Agri-Food Canada (AAFC), et al. “Evaluation of On-Farm Crop Management Decisions on Canola Productivity.” Canadian Journal of Plant Science (2014).

Aim for uniform stands

Science Edition 2014—Key practice: Uniform stands, with the same number of plants per square foot across the field and with plants at the same growth stage, are proven to increase yields. Key research: Angadi, S.V., Agriculture and Agri-Food Canada (AAFC), et al. “Yield Adjustment by Canola Grown at Different Plant Populations under Semiarid Conditions.” Crop Science 43...
