bu/acre bu/acre Average Corn Yield Up Since 1996 Introduction of Biotech Corn

Biotechnology Innovation Produces Food AND Fuel Yield growth of just 2 bushels per acre per year results in an additional 144 million bushels.* That additional corn could produce more than 403 million gallons of ethanol. * 10-year average 72 million harvested acres
