Here are the growing degree days (Base 0°C) for the Prairies from April 1 to August 4, 2014. The growing degree day map for May 19 shows how far we’ve come. Saskatoon, for example, was around 200 for the season at that time, which means canola seeded in that region in mid May has had around 1,300 GDD Base 0 since then. The table below will give an indication of where canola should be after 1,300 GDD Base 0. Click here to create this map and other AAFC maps.
