Keith Glewen is a University of Nebraska faculty member with a 100% Extension appointment in the Southeast Research and Extension Center District. He has regional and in some cases, statewide program responsibilities for agronomic and natural resource/environmental related issues, with particular emphasis in areas of agricultural profitability, on-farm research and soil and water management-stewardship. Recently, Glewen has focused his efforts on developing programs for industry consultants that support farm operators in the Midwest Region. Glewen has worked with faculty and stakeholders to successfully develop a Crop Management and Diagnostic Clinic at the University of Nebraska Eastern Nebraska Research & Development Center. Field based training sessions are offered during the growing season to provide crop consultants and industry agronomists with diagnostic training to enhance the application of best management practices in the production of row crops. In 2018, 242 participants representing 39 Nebraska Counties and 13 States estimated the value of this training to be $43.1 million dollars. In working with commodity boards, Glewen has secured funding to implement research and education programs. They have included, Soybean Management Field Days, Irrigation and Energy Management Field Days, Nebraska Soybean Day & Machinery Expo, Nebraska No-Till Conference and Nebraska Cover Crop Conference.
Early in his career, Glewen developed a very effective program with farm operators focusing on transferring field research to the farm, entitled the Nebraska Soybean and Feed Grains Profitability Project. This project engaged farm operators in eight Nebraska counties conducting on-farm research. Today the project has expanded under the umbrella of the Nebraska On-Farm Research Network.
Many of the above programs are based on partnerships developed through relative and effective programing during his career.
Besides the above, Glewen has been effective in working with area farm operators in developing and growing effective corn and soybean commodity organizations, considered to be among the most active in Nebraska.

Nebraska soybean producers are being asked to answer a survey about their soybean fields and contribute to a benchmark study of current soybean production in Nebraska. Researchers from 10 north central states, including Nebraska, are collecting the data to identify factors that may be impeding growers from reaching full yield. See what they've learned in the first two years of the study and how they hope to use the information.
End-of-season yield forecasts for irrigated and dryland corn across eight states in the Corn Belt indicate above average yields for 2016, but not the record-breaking yields predicted by USDA in their September forecast. While two states are forecast to have yields below the 10-year average (-1% to -4%), the remaining states showed above average yields ranging from 1% to 21% above the 10-year average.
The Sept. 7 corn yield forecasts show a majority of the irrigated sites expected to produce above normal, but not record-breaking yields. Forecasted yields for rainfed sites are more variable, although most are expected to be near normal. Above average yields are expected for 11 of the 37 sites studied and below-normal yields are forecast for five sites.
August 24 corn yield forecasts for 41 sites across the Corn Belt showed many near or above average. At Nebraska rainfed corn sites there is a high probability (>75%) of above-average yield at the North Platte and central east sites and a high probability (>75%) of below-average yield at the southwestern and southeastern Nebraska sites (McCook, Clay Center, and Beatrice). In irrigated corn there was a high probability of near or above average yields for all except the Beatrice site. See the story for data tables and discussion.
Simulations of 2016 end-of-season corn yield potential for 41 sites indicate high probability of near or above-average yields in irrigated fields, but much more variability across the Corn Belt for rainfed fields. Several sites in southern and northeast Nebraska and in Iowa show a higher probability of below average yields. The article includes yield forecasts for each site, along with conditions for the period contributing to the forecasts.
Corn yield forecasts, based on Hybrid-Maize simulations and input from crop experts in 10 states, were developed for 41 sites across the Corn Belt on July 27. For irrigated corn, based on this conditions at this point in the season, there is only a low probability of below average yields. For rainfed corn, the majority of the sites studied, the results are more variable across locations. The article includes yield forecasts for each site, along with conditions for the period contributing to the forecasts.
Based on modeling corn growth stage and end-of-season yield for 41 sites in 10 Corn Belt states, researchers are forecasting potential end-of-season yield in "real time" to aid in decision-making thoughout the season. On July 14 they reported that corn has already reached or is approaching silking throughout most of Nebraska and the Corn Belt, except for corn in the northern and eastern states, where growth is running behind the rest of the region.based on modeling end-of-season corn yield for 41 sites. There is a low (<20%) probability of below-average yields at all irrigated locations, except for two sites in southeastern Nebraska. The range of forecast yields at the rainfed sites is wider. There is a relatively high probability (>75%) of above-average yield at two locations in the northern states and below-average yield at three locations. See story for predicted yields and probabilities for all the sites.
The Yield Forecasting Center will be providing in-season corn yield forecasts every two weeks starting in mid-July to aid growers and the ag industry in making management, logistics, and marketing decisions through the season. The Center consists of a core team at UNL in collaboration with agronomists and extension educators from universities throughout the Corn Belt.
