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.

Corn leaves can turn red when the sugars from the photosynthesis process build up in leaves and stalks when there aren't enough kernels to store the sugar. (Photos by Megan Taylor)
Corn leaves and stalks can take on a red appearance now due to stresses earlier in the season that affected plant photosynthetic processes.

Red Corn Q & A August 24, 2018

Are you seeing red (in your corn)? Corn leaves and stalks can take on a red appearance now due to stresses earlier in the season that affected plant photosynthetic processes. Here's why.

Aug. 22 Corn Yield Forecast: Shorter Crop Cycle Did Not Lead to Below-Average Yield August 23, 2018

Corn progress and yield forecasts for 41 sites across the Corn Belt indicate near- or above-average yields for most sites. High temperatures early in the season increased the rate of corn development and led to a shorter crop cycle, but do not appear to have diminished yields.

Soybean and Corn Yield and Acreage Trends August 15, 2018

Nebraska soybean and corn yields have steadily increased from 1971 to 2017 in both irrigated and rainfed production systems. Nebraska irrigated soybean increased at a linear linear rate of 0.68 bu/ac, and irrigated corn increased at a rate of 2.17 bu/ac.

2018 Corn Yield Forecasts: Physiological Maturity Expected Before Historical Averages August 2, 2018

Corn growth simulations across the Corn Belt indicate early corn maturity of one to two weeks for most sites. Simulated corn yields for rainfed and irrigated sites across the region near or above normal at most sites.

2018 Corn Yield Forecasts as of July 11: Higher Temperature Led To Faster Corn Development July 13, 2018

Corn yield forecasts and crop growth stage estimates for the US Corn Belt, based on crop modeling and local input, start up this week for 2018. Corn development is well ahead of normal, with most sites in the central and southern fringes of the Corn Belt in the silking or grain-filling stages.

2018 Corn Yield Forecasts: Approach and Interpretation of Results June 29, 2018

Here's how the Yield Forecasting Center will be developing corn yield forecasts for 41 locations across the Corn Belt during the 2018 crop season. Modeling, using Hybrid-Maize, weather data, and on-site verification help researchers estimate yields so growers can adjust management during the season, if necessary.

Flooding and Ponding in Corn June 22, 2018

Ponding or flooding of fields affects corn differently at different stages, depending on duration of flooding and other factors. Growers should assess the potential for nitrogen loss and increase scouting for corn disease in these fields.

Figure 1. The degree of damage from standing water in this field will depend on several factors and likely will lead to direct yield losses or indirect losses from increased disease pressure.

Flooding and Ponding in Soybeans June 22, 2018

Soybean plants are generally able to withstand a fair amount of flooding in the short term; however, diseases favored by wet conditions may become a problem for the rest of the season. Research shows the length of time the soil is wet and the type of soil will affect plant injury and survival.
