Openers and Emergence

November 1, 2013

Management Practices for Optimum Canola Emergence

Principal investigator: Robert Blackshaw, Agriculture and Agri-Food Canada, Lethbridge, AB

Collaborators: Neil Harker, Eric Johnson, Bryon Irvine, Blaine Metzger (AgTech Centre), Ken Coles (Farming Smarter), Alvin Eyolfson (Battle River Research Group), Sherrilyn Phelps and Shannon Urbaniak (Saskatchewan Ministry of Agriculture).

Increasing seeding speed will reduce the precision of canola seed placement and thereby reduce the percentage of canola seeds that emerge — no matter which opener you use.

Bob Blackshaw with Agriculture and Agri-Food Canada (AAFC) led a two-year study to see how opener systems influenced canola seed emergence, and how speed influenced seed placement. The study compared six different openers in small plot replicated trials across different soil types in Western Canada at Lethbridge, AB, St. Albert, AB, Zealandia, SK, Indian Head, SK, and Brandon, MB in 2011 and 2012. Additionally, a field-scale study using farmers’ seeding equipment examined the effect of various seeding speeds on canola emergence.
