Results in most areas confirmed a significant yield hit due to the drought.
USDA, in its September crop report, reduced the Illinois corn yield estimate from 116 bushels per acre to just 110 bushels, down 47 bushels from a year ago.
“That’s a big drop,” said Emerson Nafziger, University of Illinois Extension crop systems specialist. “Especially in Southern Illinois.”
The corn yield averages in crop districts across the state ranged from just 55 bushels per acre in the southeast and 63 bushels in the southwest to 139 bushels in the northwest, the National Agricultural Statistics Service Illinois field office reported.
