KEY RESULT: Heavy tillage can increase soil compaction, reduce soil strength and reduce canola yields, especially when carried out under higher moisture conditions and in the spring, prior to planting. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Compaction Impacts on Canola Establishment” Curtis Cavers, Agriculture and Agri-Food Canada (AAFC) Portage la Prairie FUNDING: Manitoba Canola Growers Excessive precipitation...
Read More KEY RESULT: This study compared three canola seeding rates (5, 10 and 15 seeds per square foot) with small and large seed size lots from two different hybrids. It concluded that the most economic and least risky seeding rate to achieve adequate plant stand population is about 10 seeds per square foot because the response...
Read More KEY RESULT: High-yielding canola with high inputs can be sustainable in an area in which it is adapted. Early-planted full season canola will provide the most sustainable “on-farm” footprint. Canola with high inputs can be the focal point of a crop rotation and can create economic flexibility to allow for a broad crop rotation plan....

KEY RESULT: This one-year study supports previous recommendations that in-soil banding of nitrogen fertilizers during seeding or near to the time of seeding is a best management practice to enhance nitrogen use efficiency (NUE). PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Impact of Source and Placement of Nitrogen and Sulphur Fertilizers on Canola,” Ramona Mohr, AAFC Brandon FUNDING:...
Read More KEY RESULT: This Manitoba study found that nitrogen source did not affect canola yield, but fertilizer placement did. Fall surface application of granular urea and enhanced efficiency fertilizer products produced lower yield (13 bu./ac.) than spring surface applications of the same products. For spring applications, surface placement had lower yields (3 to 5 bu./ac.) than...
