Hybrid and seed lot choice could influence seeding rate

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...

Seed early and fertilize well for economics and environment

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....

Band nitrogen to reduce losses, improve NUE

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:...

Canola yields lower with fall surface-placement of nitrogen

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...

Foliar-applied P can help with in-season deficiency

KEY RESULT: While this Saskatchewan study did show a yield response for foliar-applied phosphorus (P) when compared to a control without any P fertilizer, the best practice is still to meet crop needs with fertilizer applications before or at the time of seeding. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Crop response to foliar-applied phosphorus fertilizers,” Jeff Schoenau,...
