Record-early corn crop promising as condition rates remain good
As of the week ending June 10, USDA’s weekly Crop Progress report from the National Agricultural Statistics Service (NASS) rated 66 percent of this year’s corn crop as good or excellent, compared with 69 percent last year. Of the crop, 8 percent was rated poor or very poor, compared to 6 percent a year earlier. The percentage of corn rated fair is slightly greater than last season at 26 percent, compared with 25 percent a year earlier. Pennsylvania, South Dakota, Minnesota, and North Dakota had the highest condition ratings with 80 percent exceeding good or excellent. Missouri, Indiana, and Tennessee had the highest very poor to poor ratings.
Early-season crop condition ratings provide little indication of final yields as rainfall and temperatures over the next several weeks will ultimately determine this year’s production. The percentage of the crop rated good or excellent was 69 percent in both 2010 and 2011 for reporting weeks comparable to June 10 this year. The U.S. corn yield in 2009 was a record 164.7 bushels per acre, 7.7 bushels above the 1990-2010 trend. The 2011 yield was 147.2 bushels per acre, 14.5 bushels below the 1990-2010 trend.
