Planting Date:  April 28, 2004
Harvest Date: September 8, 2004
Text Box: * A brief hailstorm occurred 11 days prior to harvest of this trial. There was very little stem breakage and almost all yield loss was the result of hail shattering.  A rough estimate of shatter 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 hail shatter between varieties may have been due to the varieties genetic susceptibility to shatter and/or its maturity.  The LSD 5% for hail shatter is 45, so for example, a variety with a shatter of 100 or 140 would not be significantly different from one another.  Please observe both the hail shatter and yield data carefully when using this data.
