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.

This article discusses data and data collection for the Yield Forecasting Center forecasts of crop phenology and yield for 2017, including a map of the site locations and specific data on crop management and soil types for each site.
Have you ever wondered how fast corn roots grow? Colleagues at Iowa State University have a number: more than 2 ¾ inches per leaf stage. That's about one inch per day! Soil cores were taken in the row and in the center between two rows. They used the cores to identify the presence of roots (depth and lateral growth).
Widespread yellowish corn seedlings this spring may be due to the slightly sun- and heat-starved seedlings running out of the seed’s stored energy before the main nodal roots take over. A little sun and heat should green them up without affecting yield.
Nebraska soybean and corn yields steadily increased from 1971 to 2016, in both irrigated and rainfed production fields. Charts based on USDA National Agricultural Statistics Service numbers track these changes.
Heavy rains of 2 to more than 4 inches in south central Nebraska May 15-19 have led to ponding or flooding in many fields. Survival of young corn plants under these conditions depends on several factors, described here.
A gallery of photos showing decreased effect of yellow cross-banding in corn leaves in south central Nebraska one week after initial report in CropWatch. This effect was due to pre-emergent cold temperatures and is not expected to affect yield.
