Feasibility of growing winter types of Brassica rapa in Alberta

Key practice: Growers in southern Alberta may want to consider winter B. rapa as a suitable alternative to hybrid spring canola (B. napus), which could be a good fit with other winter crops grown there, especially winter wheat. Project title, Lead researcher: “Evaluation of winter Brassica rapa for cultivation in Alberta,” 2007-11, Habibur Rahman, University...

Precise seed-to-seed spacing not necessary for canola

Key Practice: The key step in seed placement is to achieve the overall target population with some aspect of uniform distribution and depth. Precision tools to enhance seed spacing in the row provide little evident economic benefit. Project Title, Lead Researcher: “Seeding rates for precision seeded canola,” 2012-14, Gazali Issah, Western Applied Research Corporation Grower...

Reseed when fewer than two plants per square foot

While hybrid canola has a high degree of phenotypic plasticity that allows it to compensate for low plant populations, growers need to know when the population is likely too low to compensate for the reduced plant stand. Reseeding is more likely to provide an economic benefit when: the population is below 20 plants per square...

Glyphosate-resistant kochia survey

Key practice: Taking action to manage glyphosate-resistant kochia before it is visible in the field is critical to success. Use a rotation of broadleaf control products with good activity on kochia. Project title, Lead researcher: “Glyphosate-resistant kochia (Kochia scoparia L. Schrad.) in Saskatchewan and Manitoba,” 2013-14, Hugh Beckie, Agriculture and Agri-Food Canada (AAFC) Grower organization...

Annual soil tests improve nitrogen returns

Key practice: Predicting how much nitrogen is reserved in the soil is difficult. Given its high cost in canola production, conducting an annual soil test on each field to determine appropriate rates is a good idea. The wild card is moisture supply throughout the growing season. Project title, Lead Researcher: “Long-term effects of different soil...
