Timeline: 2009 – 2012
Canola emergence is often only 40-70% of planted seed. Slow seeding speeds (4 mph) may increase canola emergence, but farmers need to seed large areas in a short time
To determine how important seeding speed, seeding depth, and opener type are on canola emergence
Collaborators: Blaine Metzger, AG Tech Centre; Farming Smarter
newly emerged canola
Locations: Lethbridge & Lacombe, AB; Scott & Indian Head, Sask.
Established experiments on cereal stubble 2008-2010. Seeded two cultivars of canola at 150 seeds/m2 with knife openers at 2 depths (1 & 4 cm) driving two speeds (4 & 7 mph).
Throughout the project, we saw a general trend of reduced canola emergence with higher seeding speeds in Alberta. 13 per cent of farms in 2011 and 25 per cent of farms in 2012 had reduced emergence with higher speeds in Saskatchewan. Excellent soil moisture may have been the great equalizer in these studies.
