Probability of 2021 yield potential map

2021 Corn Yield Forecasts as of July 14

July 14, 2021
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.

2021 Corn Yield Forecasts: Approach and Interpretation of Results

June 30, 2021
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 2021 season.

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.

2018 Corn Yield Forecasts: Approach and Interpretation of Results

June 29, 2018
Here's how the Yield Forecasting Center will be developing corn yield forecasts for 41 locations across the Corn Belt during the 2018 crop season. Modeling, using Hybrid-Maize, weather data, and on-site verification help researchers estimate yields so growers can adjust management during the season, if necessary.

2017 Corn Yield Forecasts as of September 20

September 21, 2017
Crop modelers wrap up their forecasts of rainfed and irrigated corn yields across the Corn Belt for 2017, noting above-average yields for about 80% of the irrigated sites and more than 60% of the rainfed sites. Irrigated yields ranged from 11%-17% over long-term averages at those sites and rainfed yields at those sites were 13%-40% above average. View data for all the sites.

Forecast of end-of-season irrigated corn yields in Nebraska and Kansas

2017 Corn Yield Forecasts as of August 30

September 1, 2017
Forecasts for end-of-season corn yields improved across much of the Corn Belt since the early August forecast. View crop stage and yield forecasts as well as weather data. In Nebraska predictions are for near to above average corn yields for most sites, except northeast and northwest sites.

Maps showing likelihood of yield deviations for rainfed corn at various sites.

2017 Corn Yield Forecasts as of Aug. 9

August 11, 2017
Corn yield forecasts for Nebraska sites indicate near-average to above average yields for most irrigated sites. There was much more yield variability for rainfed locations where three of the sites were forecast with a 50%-100% chance of below-normal yields and three were forecast for normal yields, while one was near average.
