Canola growers who consistently seed at a shallow depth of one centimetre can reap significant benefits. These include improved emergence density, decreased days to emergence, increased canola ground cover, decreased days to flowering and maturity, and decreased green seed levels.
Neil Harker with Agriculture and Agri-Food Canada (AAFC) in Lacombe, AB led a three-year project to study factors affecting canola emergence and quality, including seed type, seeding speed and seeding depth. Canola seed is a substantial input cost and poor canola stand establishment is a continuing concern for canola growers. On average, only 50 percent of planted seeds emerge, even when seed has a germination analysis above 90 percent.Open the PDF to read the entire research summary from the 2013 Science Issue of Canola Digest
