According to the 2008 Varieties of Grain Crops publication, the relative maturity of AC Barrie (the check variety) hard red spring wheat is 100 days. Assume the variety you are seeding is AC Intrepid. The maturity rating for AC Intrepid is -3, which means 3 days earlier than AC Barrie or 97 days.
For the purpose of this example, assume the first fall frost date falls in the August 31 - September 6 range. Using September 6 and counting back 97 days means that June 1 would be the final date liability would be accepted for AC Intrepid hard red spring wheat. |
