Oct. 16 Corn Yield Forecast - End of Season Report

October 19, 2018
The end-of-season corn yield report finds that high temperatures during vegetative stages had little impact on forecasted yield potential. This is the final article in the series looking at simulated crop stages and yield forecasts for 41 locations across the US Corn Belt.

Aug. 22 Corn Yield Forecast: Shorter Crop Cycle Did Not Lead to Below-Average Yield

August 23, 2018
Corn progress and yield forecasts for 41 sites across the Corn Belt indicate near- or above-average yields for most sites. High temperatures early in the season increased the rate of corn development and led to a shorter crop cycle, but do not appear to have diminished yields.
