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.

Q and A: Why is Corn Emergence Uneven This Year?

May 29, 2020
Planting conditions seemed to be “perfect” this year. This allowed a large percent of corn and soybean acres in Nebraska to be planted earlier than in previous years. Because conditions seemed so good, the question is why emergence has been uneven in some fields this year.

Projecting Dates for Ending Reproductive Stages of a Soybean Crop Using SoyWater

October 9, 2019
How did the 2019 growing season affect the date of R7 (PM) in soybean varieties differing in MG (1.1 to 4.1) and planting date in eastern Nebraska? Take a look at graphs showing seasonal vegetative (Vn) and reproductive (Rn) development versus calendar date and compare the data with field photos.

Map showing probability of deviation from normal yields for rainfed sits in Nebraska and Kansas

2019 Corn Yield Forecasts as of September 17

September 19, 2019
Forecasted end-of-season yields for rainfed corn across the Corn Belt indicate above-average yield at two-thirds of the sites, with yields well above historical averages in Nebraska, Kansas, and Missouri. See data for individual irrigated and rainfed sites.

2019 Corn Yield Forecasts as of August 21

August 22, 2019
There is a high probability of near- or above-average yields at all but two of the 37 locations studied. Corn has reached dough stage at most locations, except for irrigated corn in western and north-central Nebraska, northern North Dakota and Minnesota, and the eastern fringe of the region (Indiana, Michigan, and Ohio).
