Stubble Height

November 1, 2013

Enhancing Canola Emergence with Innovative Stubble Management Practices and Use of Crop Establishment Aids

Principal investigator: Aaron Glenn, Agriculture and Agri-Food Canada, Brandon, MB

Collaborators: Mike Cardillo, Paul Bullock, Herb Cutforth, Guy Lafond and William May

Whether canola is seeded into tall or short wheat stubble, there is no impact on yield, according to this study.

The three-year study measured how crop residue height and the amount of straw on the soil surface influenced the establishment, disease level and yield of canola. Trials were conducted at four sites in 2011 — Swan Lake, MB, Indian Head, SK, Swift Current, SK and Grimshaw, AB. Sites were added at Lethbridge, AB, Falher, AB and Brandon, MB in 2012. Preceding spring wheat stubble was cut at 20 cm (short), 50 cm (tall), and/or harvested with a stripper header. Emergence counts, plant stand counts, final biomass weights and disease assessments were recorded.
