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...

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...
Read More 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...
Read More Canola growers can experience substantial decreases in yield due to sulphur deficiency. The abstract to the Grant, Malhi and Karamanos review cited above begins with this: “(Canola) has a high concentration of sulphur in its tissue and seed and a particularly high demand for sulphur relative to its yield potential. Therefore, effective sulphur management is...

Growing spring canola in the moderately short growing season of the Canadian Prairies always tests the tipping point between maximum maturity time (to produce maximum yield) and avoiding the first frost. With growers taking on more acres than ever, the time crunch at harvest can make it tempting to begin swathing early. But the yield...
