Iowa corn and soybean yields rebounded in 2013 after the severe drought of 2012, but no counties in the state posted average yields of 200 bushels per acre in corn or above 60 bushels per acre in soybeans, according to a recent report from the U.S. Department of Agriculture’s National Agricultural Statistics Service. The wet, cool spring followed by a hot, dry summer led to very uneven yield patterns, the report showed.
Dubuque County in northeast Iowa posted the highest average corn yield at 196.4 bushels per acre, followed by O’Brien, Sioux and Lyon counties in northwest Iowa. In total corn production, Kossuth County in north-central Iowa topped the list at 50.9 million bushels; Plymouth and Pottawattamie were second and third.
The top average soybean yield was Sioux County, with an average yield of 59.9 bushels per acre, followed closely by Lyon and O’Brien counties, also in northwest Iowa. Four counties, Kossuth, Plymouth, Pottawattamie and Sioux, topped the state with soybean harvests of 9.7 million bushels.
