Project Code: 3.4.1

Final Report: April 2013

Summary: In a three-year project, researchers conducted surveys for harvest losses of canola on farms across western Canada. Researchers concluded that total on-farm harvest losses in canola are a complex phenomenon with many interacting variables that are difficult to separate. However, management factors that contribute to higher canola yield and harvest management variables such as combine speed and combine separator type contributed significantly to harvest losses, clearly indicating that producers have some level of control over the amount of canola seed that is left behind in the field after
harvest.
