Text Box: *High sustained winds occurred six days prior to harvest resulting in shattering in some varieties.  A rough estimate of shatter seed loss on each plot was recorded.  A 1000 KWT of 31 grams would require 20 seeds/ft2 to equal one bushel per acre.  This number would vary depending on the kernel size of the variety. Differences in shattering between varieties may be due to the varieties genetic susceptibility to shatter and/or it maturity.  The LSD 5% for shatter is 43, so for example, a variety with 50 or 90 seeds/ft2 seed loss would not be significantly different from one another.  In 2004, hail shattering was also recorded in the hrsw trial at Langdon.  Please refer to the 2004 table for that information.  Please observe both the shatter and yield data carefully when using this data.
Lodging:  No lodging in trial.
Planting Date:  May 16   Harvest Date:  September 6
