Corn Production
- 2015 Forecasted Corn Yields Based on July 15 Hybrid Maize Model Simulations. Based on yield forecasts made this week, there is a high (>80%) probability of near- or above-average irrigated yields at most locations in Nebraska (7 of 10 sites); however, researchers caution it is still early in the growing season and factors may change. Yield forecasts for dryland corn are also favorable. See specific yield day and long-term yields for selected sites.
