Science Edition 2014—Early spring seeding typically benefits canola yield and quality. An early planting date enables the crop to take advantage of good spring moisture, avoid some heat stress at flowering, and reduce the risk of fall frost damage. Key practice: Crops seeded early (in late April or early May, depending on the region) will out-yield canola...

Science Edition 2014—Key practice: Control weeds early through a combination of pre-seed weed control and one in-crop application before the four-leaf stage. Key research: Harker, K. Neil, Agriculture and Agri-Food Canada (AAFC), et al. “Field-Scale Time of Weed Removal in Canola.” Weed Technology (2008). Harker, K. Neil, AAFC, et al. “Seeding Rate, Herbicide Timing and Competitive Hybrids...

Science Edition 2014—Key practice: Ground speed and mechanical adjustments to the combine can reduce harvest losses and increase yields. For growers who want to try straight combining, start with one field with uniform maturity and high yield potential. Key research: Gulden, R.H., University of Manitoba, et al. “Evaluation of Harvest Losses and Their Causes in Canola Across...

Science Edition 2014—Key practice: Optimum seeding depth is ½” to 1″ below the press wheel furrow. This reduces days to emergence and improves plant population and uniformity, which produce season-long benefits. Key research: Harker, K. Neil, Agriculture and Agri-Food Canada (AAFC). “Seeding Depth and Seeding Speed Effects on No-Till Canola Emergence, Maturity, Yield and Seed Quality.” Canola...

Science Edition 2014—Key practice: Use soil tests, ideally taken at consistent locations (GPS helps), and base rate decisions on soil test recommendations. Key research: S.A. Brandt, Agriculture and Agri-Food Canada (AAFC), et al.“Seeding rate, fertilizer level and disease management effects on hybrid versus open pollinated canola (Brassica napus L.)” Canadian Journal of Plant Science, 2007.
