While there’s already been a lot of work done on the matters of volunteer canola issues and canola harvest loss, recent research from the University of Manitoba aims to get a better handle on the problem of volunteer canola in soybeans.

Rob Gulden, a U of M researcher and acting associate head of the plant science department, says many variables affect canola harvest loss rates — and they’re tough to isolate.

There are mechanical factors, including combine speed, settings and separator type. Your chosen canola variety will also affect the amount of pod shatter.

Don Flaten, a professor emeritus in the soil science department at the University of Manitoba, says one of the most common symptoms of potassium deficiency is when older parts of the plant appear chlorotic and leaves begin to yellow, especially at the tips and margins.
