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.

Wind-Damage to Corn

July 16, 2020
Prior to storms July 8-9, plants were nearing tassel, a critical time for photosynthesis and pollination. These storms resulted in “flattened” corn from lodging/leaning in addition to bent and snapped plants. "Recovery" depends on a variety of factors.

Corn Ear Development Impacts from Post-emergence Pesticide Applications

June 4, 2020
Corn ear abnormalities have been noted the past few years. Tracing back the information on various field calls often pointed to a misunderstanding of proper growth stages when making post-emergence herbicide applications in addition to pre-tassel fungicide and insecticide applications.

Planting Date Impact on Corn Growth and Ear Issues

May 14, 2020
Despite the above-average yields in recent years, there has been reports of ear formation issues in corn that ranged from sites in the Texas Panhandle, Colorado, Nebraska, Iowa, and Illinois. Does planting date play a role?

Spring-planted Cover Crops for Weed Control in Organic Soybean

March 25, 2020
Weed control in organic soybean usually includes frequent pre-plant tillage operations but spring rains often make it difficult to get into the fields for timely tillage. As a result, weed pressure can be high. Cover crops can help suppress weeds, but after corn harvest it is often too late to establish cover crops. Spring-planting cover crops may be an alternative to fall-planting.

Corn and Clouds: “…from both sides now…”

November 6, 2019
Solar radiation and temperature data for the third week of August in central Nebraska indicates it likely contributed to the lower-than-expected yields being reported by many growers this year.
