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...

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,...

KEY RESULT: Placing phosphate fertilizer in the seed row has its challenges because seed damage can occur at fairly low rates. Rather than short the crop with a low seed-placed rate, this study found that the full recommended rate placed outside the seed row is the better option. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Enhancing Canola Production...

KEY RESULT: This study confirms there is significant potential for canola residues to enhance N2O emissions relative to those associated with wheat, flax and pea residues. This potential appears to be associated with the release and subsequent transformation of glucosinolates into a variety of bioactive compounds during crop residue decomposition. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Identifying...

KEY RESULT: This study validated the nominal economic threshold of 25 per cent defoliation. It also determined significant associations between landscape structure and flea beetle abundance, weather and flea beetle abundance, and plant density and flea beetle damage. As well, two flea beetle predators were confirmed. PROJECT TITLE, PRINCIPAL INVESTIGATOR: “Integrated approaches for flea beetle...
