Learning from the 2025 Corn Season

By Scout Nelson

The latest episode of Minnesota CropCast takes a deep look at the 2025 Minnesota corn season and how its challenges can guide better decision-making for 2026. Hosted by Dave Nicolai and Seth Naeve, the episode features University of Minnesota Extension Corn Agronomist Dr. Jeff Coulter, who helps explain the major events that shaped this year’s crop.

The 2025 season was unusual from the start. It began with a very early and rapid planting window, followed by several weeks of moderate weather that supported strong early growth. However, conditions changed when August brought unseasonably cool temperatures.

This shift slowed development and affected yield potential in many areas. Late-season drought in West Central Minnesota added stress, reducing grain fill and contributing to uneven performance across the state.

The conversation also highlights the notable disease pressure experienced this season. While Minnesota growers are familiar with common corn diseases, this year brought an unusually heavy outbreak of Southern Rust. Its fast spread and impact on plant health created new challenges and emphasized the importance of strong disease resistance in future hybrid choices.

Looking toward 2026, Dr. Coulter discusses the evolving traits available in corn hybrids. Insect and disease resistance packages continue to expand, offering more targeted protection. He also notes the growing interest in “short stature” corn hybrids, which are designed to stand better in strong winds, allow easier management and reduce lodging risk.

The episode encourages listeners to use the lessons of 2025 as a guide when preparing for the next season. Understanding how weather patterns, disease outbreaks, and crop genetics interact can help producers make informed and resilient decisions.

Minnesota CropCast offers weekly discussions about agronomic issues and research affecting the state’s crops. The hosts are joined by experts across disciplines who share insights that help strengthen future production.
