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.

Crop modelers wrap up their forecasts of rainfed and irrigated corn yields across the Corn Belt for 2017, noting above-average yields for about 80% of the irrigated sites and more than 60% of the rainfed sites. Irrigated yields ranged from 11%-17% over long-term averages at those sites and rainfed yields at those sites were 13%-40% above average. View data for all the sites.
Forecasts for end-of-season corn yields improved across much of the Corn Belt since the early August forecast. View crop stage and yield forecasts as well as weather data. In Nebraska predictions are for near to above average corn yields for most sites, except northeast and northwest sites.
Interested in estimating your corn or soybean yields? Most of the components for corn yields—except seed weight—are set. Check out these Nebraska Extension videos and guides from Kansas and Iowa Extension for photos and how-to's on assessing your crop and estimating yield.
Corn yield forecasts for Nebraska sites indicate near-average to above average yields for most irrigated sites. There was much more yield variability for rainfed locations where three of the sites were forecast with a 50%-100% chance of below-normal yields and three were forecast for normal yields, while one was near average.
Considering the day to day and week to week variability in weather we’ve experienced and the wide range of regional conditions across Nebraska this year, scouting fields for kernel set and overall condition may be more important than ever. Check out these corn reports from across the state.
Corn growth stages are estimated for 41 sites in 10 states and yields are estimated for select irrigated and rainfed sites, based on the Hybrid-Maize model and input from specialists and educators across a 10-state area as of July 18, 2017. The authors note that these early season yield forecasts vary widely, particularly for rainfed fields, and may change considerably by end of season.
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.
