*Yield = pounds of seed/acre after recleaning, adjusted to 10% moisture.
**%H2O = seed moisture after recleaning.
Test weights are in pounds per bushel. Canola official weight = 50 pounds/bushel.

Chickasha was direct combined June 17 and was moderately lodged with severe shattering due to severe thunderstorms with hail and high winds before harvest. Haskell was direct combined June 15, and was also lodged with severe shattering due to a thunderstorm with small hail. See weather information below.
