When you consider the temperatures across the prairies even a month ago, it’s hard to believe we’d be here now talking about the effects of high temperature on canola. That’s the nature of life on the prairies though. While prolonged periods of high heat may not be in the cards for most of the prairies, the effects of that exposure can have real consequences for canola. Yield loss, seed quality and oil quality can all be affected by too much heat. To what degree those qualities are affected depends on things like what stage of development the plant is affected at, and what other stresses are acting against that plant.
