Map showing likelihood of yield deviation from the long-term average yield potential for irrigated corn sites in Nebraska and Kansas.

2019 Corn Yield Forecasts as of August 21

August 22, 2019
There is a high probability of near- or above-average yields at all but two of the 37 locations studied. Corn has reached dough stage at most locations, except for irrigated corn in western and north-central Nebraska, northern North Dakota and Minnesota, and the eastern fringe of the region (Indiana, Michigan, and Ohio).

Growth stages of corn at rainfed sites in monitored by Corn Yield Forecast Center

2019 Corn Yield Forecasts as of July 15

July 19, 2019
Corn is still in vegetative stages across much of the Corn Belt. At this point, delayed planting doesn't appear to have affected yields at irrigated sites. Yields for rainfed sites vary considerably, with those on the western edge trending above normal.
