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.

Yield losses from hail storms will depend on the timing and severity of the hail, and subsequent environmental conditions. Regardless of the level of damage, farmers should be patient when evaluating early-season hail damage in corn and wait 7–10 days after a hail event to allow for crop regrowth. See more on replant decision, yield potential of surviving plants, hail and bacterial plant pathogens.
While corn planting has been delayed in areas of the state due to recent rains, it's too early to consider switching hybrids or switching to soybeans. The author addresses some key points to consider for those waiting to plant and those who planted early and may need to assess stand viability.
With dry conditions the last week and a forecast for rain this weekend, corn planting is progressing rapidly in Nebraska. While warm conditions may persist through April, the potential for freeze risk can still be high when early-planted corn emerges.
Several factors affect corn and soybean survival in flooded soils at early season growth stages. The oxygen supply in saturated soils becomes depleted within about 48 hours. Cool air temperatures will help increase the possibility of survival, but germinating seed and plants would not be expected to survive more than four days.
