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.

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.

How Row Spacng Affects Irrigated Soybean in Southwest Nebraska

April 27, 2018
While continuous corn is the most common cropping sequence in southwest Nebraska, adding soybeans to a rotation could help break pest cycles. On-farm research comparing 15- and 30-inch soybean row spacing found increased yields of 4-12 bu/ac with an average 7 bu/ac increase with 15-inch rows.

Nebraska Cover Crop Conference Feb. 15 for Corn, Soybean Growers

January 26, 2018
Cover crops offer many benefits, such as improved soil heath and reduced erosion. The challenges lie in the details, including what cover crops to use and how to use them. The Feb. 15 Nebraska Cover Crop Conference tackles these topics for growers using a corn/soybean rotation.

2017 Corn Yield Forecasts as of September 20

September 21, 2017
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.
