2016 Corn Yield Forecasts as of July 27

July 28, 2016
Corn yield forecasts, based on Hybrid-Maize simulations and input from crop experts in 10 states, were developed for 41 sites across the Corn Belt on July 27. For irrigated corn, based on this conditions at this point in the season, there is only a low probability of below average yields. For rainfed corn, the majority of the sites studied, the results are more variable across locations. The article includes yield forecasts for each site, along with conditions for the period contributing to the forecasts.

2016 Corn Yield Forecasts as of July 13

July 14, 2016
Based on modeling corn growth stage and end-of-season yield for 41 sites in 10 Corn Belt states, researchers are forecasting potential end-of-season yield in "real time" to aid in decision-making thoughout the season. On July 14 they reported that corn has already reached or is approaching silking throughout most of Nebraska and the Corn Belt, except for corn in the northern and eastern states, where growth is running behind the rest of the region.based on modeling end-of-season corn yield for 41 sites. There is a low (<20%) probability of below-average yields at all irrigated locations, except for two sites in southeastern Nebraska. The range of forecast yields at the rainfed sites is wider. There is a relatively high probability (>75%) of above-average yield at two locations in the northern states and below-average yield at three locations. See story for predicted yields and probabilities for all the sites.

2016 Corn Yield Forecasts: Approach and Interpretation of Results

June 30, 2016

The Yield Forecasting Center will be providing in-season corn yield forecasts every two weeks starting in mid-July to aid growers and the ag industry in making management, logistics, and marketing decisions through the season. The Center consists of a core team at UNL in collaboration with agronomists and extension educators from universities throughout the Corn Belt.
