Returns were calculated by multiplying the 2006 yield by protein premium or discount paid at the Southwest Grain Terminal located at Gladstone on August 30.  The price paid on this date was $4.14/bu for a grain protein concentration was 14%.  $.02/bu was paid for each additional 0.2% increase in grain protein up to 15%.  $.01/bu was paid for each additional 0.2% increase in grain protein from 15% to 16% protein, above which an additional premium was not paid.  Grain was discounted $0.02/bu for each 0.2% reduction in grain protein from 14% to 11%, below which no additional discount was assigned.  Returns factored in discounts for grain with a test weight <58 lb/bu [-$0.02/bu for 0.5 lb/bu between 58 and 57 lb/bu; -$0.03/bu for 0.5 lb/bu between 57 and 55 lb/bu; -$0.04/bu for 0.5 lb/bu between 55 and 54 lb/bu; and -$0.05/bu for 0.5 lb/bu between 54 and 50 lb/bu].
