Canola School: Heat blast's impact on final yield

For the reproductive phase of canola, temperatures above 27 degrees C can cause heat blast. As Justin Nanninga, from Neeralandia, Alberta, explains in this Canola School, heat blast is most costly during those first two weeks of flowering, as most of the damage will occur on the main stem. In very hot weather, eventual yield can be cut by as much as 20 percent. Find out more on the impact from this RealAgriculture report at the link below.
