Watch for heat effects in canola
By Top Crop Manager
July 9, 2014 - The heat is (finally) here on the Prairies, and canola producers know that hot days (28C-30C and up) and warm nights (16C and up) from bud to mid-flowering stages can have a devastating effect on canola yield.
The Canola Council of Canada (CCC) advises that although cool nights offer some recovery from hot days, warm nights do not provide a recovery period, and more flowers are aborted, producing blanks along the stem. Even with a few days of heat, it can take a week for hormone balance and regular pod formation to return.
