2020 Corn Yield Forecasts: End-of-season Forecasts Suggest Near-average Yields for the Region

September 17, 2020
Our forecasts suggest a near-average year for irrigated corn at most sites. For rainfed corn, the scenario is diverse across regions.

August 27, 2020
Compared with our previous forecasts, there is still a high probability of near-average yields for the majority of the irrigated sites. For rainfed corn, the scenario is diverse across regions.

July 16, 2020
Although it is still too early to make strong inferences about end-of-season yields for irrigated corn, there is a relatively high probability for near-average yields for a majority of sites.

2020 Corn Yield Forecasts: Approach and Interpretation of Results

July 9, 2020
The Yield Forecasting Center (YFC) will provide real-time information on corn phenology and forecasts of corn yield potential every three weeks, starting in mid-July, to aid growers and ag industry in making management, logistics, and marketing decisions through the 2020 season.

2019 Corn Yield Forecasts as of September 17

September 19, 2019
Forecasted end-of-season yields for rainfed corn across the Corn Belt indicate above-average yield at two-thirds of the sites, with yields well above historical averages in Nebraska, Kansas, and Missouri. See data for individual irrigated and rainfed sites.

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).
