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.

From the 1960s to the 2000s corn hybrids have changed dramatically in appearance and yield. Nutrient content, concentrations and partitioning also have changed and are the focus of this article for the Nebraska Crop Management Conference Jan. 28-29.
Researchers report their findings from a one-year cover crop study at two sites in western Nebraska to study the impact of planting and termination dates and cover crop species selection. This article is part of the Crop Production Clinic Proceedings 2019.
Across Nebraska, the use of cover crops is increasing. Most commonly, winter cover crops are planted during the fallow period between corn or soybean harvest and the next crop. However, other windows for cover cropping exist in Nebraska.
For successful marestail management in the fall, apply herbicides after harvest while weather conditions remain favorable (air temperature above 50°F). Effective control now may negate the need for an early spring burndown application.
In trials conducted at three research stations in eastern, northeastern and south-central Nebraska, researchers investigated rye productivity and its ability to scavenge N when grown as a cover crop between full-season corn and soybeans.
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.
