2020 Corn Yield Forecasts as of August 4

August 6, 2020
Similarly to our previous forecast, there is a high probability of near-average yields for the majority of the irrigated sites. For rainfed corn, the scenario is diverse across regions.

2020 Corn Yield Forecasts as of July 14

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.

Corn and Clouds: “…from both sides now…”

November 6, 2019
Solar radiation and temperature data for the third week of August in central Nebraska indicates it likely contributed to the lower-than-expected yields being reported by many growers this year.

Map showing probability of deviation from normal yields for rainfed sits in Nebraska and Kansas

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).

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.
