On Sept. 12, the USDA released revised projections of 2013 state corn and soybean yields. Also released were 2013 projected crop reporting district (CRD) yields for Illinois, Indiana, Iowa, Kansas, Missouri and Texas. These projected yields are compared to 2013 trend yields to assess which areas of the country are having better relative corn and soybean yields than other areas.
Within the Corn Belt, the highest corn and soybean yields relative to trend occur in the east. Yields become lower moving west through Iowa. Lower corn yields in the western Corn Belt will push down national yields from levels that could have occurred had the entire Corn Belt had yields at or above trend. The worst relative soybean yields are in Iowa and Missouri.
