Roger Elmore, is an University of Nebraska–Lincoln agronomy and horticulture professor, Heuermann Chair and interim associate department head. Elmore, a Nebraska Extension cropping systems specialist and Water for Food Daugherty Global Institute Faculty Fellow, has spent his entire career addressing agronomic issues relevant to the immediate needs of crop producers. He provides research information that is science-based, timely, and relevant to a diverse audience. Elmore has a long history of applied crop production research and extension programs focused on maintaining or increasing crop production, profitability, and water use efficiency by seeking and demonstrating environmentally sound production practices. His focus is on research and developing, teaching and extending timely and pertinent crop management information for farmers, agribusiness, extension personnel and students. His most significant research contributions have centered on evaluating corn growth and yield response to extreme weather events. He has been able to engage diverse groups based on this research with high-impact extension programming. He co-leads a cover crop research project supported by the Nebraska Soybean Board and the Nebraska Corn Board. He has served as a consultant for various organizations across the globe and he was worked on projects in Ghana, China, Argentina and Puerto Rico. He was employed with the University of Nebraska–Lincoln for 24 years before spending nearly nine years as a corn extension specialist at Iowa State University where he lead development of the “Corn growth and development” extension publication — one of his most important extension contributions to date. He returned to Nebraska in 2014 as a cropping systems agronomist. Having a successful career as a cropping systems agronomist focusing primarily on corn and soybean production, Elmore believes in the synergism of effective teams and has been able to develop and deliver effective state, regional, national and international programs.

Stalk Quality Concerns Widespread in Areas of Nebraska

September 27, 2019
The effects of late planting and stressful growing conditions throughout much of the season are showing up now in poor stalk quality in corn. Growers are encouraged to scout fields and harvest those most at risk of lodging first. Here's why and what to look for.

How Does Cool Cloudy Weather Affect Corn During Grain Fill?

September 20, 2019
Cool or cloudy weather in late August during the grain-fill period can enhance or reduce yield, often depending on whether there's an early frost.

The Big Unknown in Corn Yield Forecasts

June 27, 2019
Each year surveys and models are used to forecast final corn yields as the crop progresses through the season. Cropping Systems Specialist Roger Elmore looks at two forecast systems and examines 10 years of USDA National Agricultural Statistics Data to see how forecasts deviated from actual yields.

Looking Back at Corn Planting Progress and Fieldwork Day Records: 1996 -2019

June 21, 2019
How do this year's corn planting delays compare with other years here and those in Illinois. After observing fields from Nebraska to Illinois on a recent trip, agronomist Roger Elmore digs into agricultural statistics dating back to 1996 to see just how this planting season and fieldwork days compare with previous ones.

Part of a row of corn struggling to survive
These plants, in a Clay County corn field, are in deep water and deep trouble! The bright vibrant greens of typical V2 to V3 seedlings are replaced with sickly yellows, indicating plummeting chlorophyll readings and photosynthesis. Roots of these oxygen-starved plants are no longer growing and are likely dying. The soil to which they are anchored has changed dramatically and full plant recovery is likely not possible.
