Abstract

The August 2010 corn yield forecast by the USDA–NASS is 179 bushels per acre (bu/acre) for Iowa. If this yield is realized, 2010 will boast the third highest yield in Iowa’s history behind 2004 (181 bu/acre) and 2009 (182 bu/acre). We need to remember that the USDA-NASS August forecast is derived largely from July ear counts with some ear dimensions, combined with ear weights from the last five years. The next forecast, Sept. 10, will include more ear parameter measurements and actual ear weights providing a more accurate representation of harvestable yields. USDA-NASS uses a complex set of statistical models to forecast grain yields. This is the best source for reliable yield forecasts.
