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.

Probability of yield deviation for normal for irrigated corn, model ran July 18, 2017

2017 Corn Yield Forecasts as of July 18 July 19, 2017

Corn growth stages are estimated for 41 sites in 10 states and yields are estimated for select irrigated and rainfed sites, based on the Hybrid-Maize model and input from specialists and educators across a 10-state area as of July 18, 2017. The authors note that these early season yield forecasts vary widely, particularly for rainfed fields, and may change considerably by end of season.
