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.

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.

Forecast of end-of-season irrigated corn yields in Nebraska and Kansas

2017 Corn Yield Forecasts as of August 30

September 1, 2017
Forecasts for end-of-season corn yields improved across much of the Corn Belt since the early August forecast. View crop stage and yield forecasts as well as weather data. In Nebraska predictions are for near to above average corn yields for most sites, except northeast and northwest sites.

Recap of 2017 Eastern Nebraska Winter Wheat Crop

August 31, 2017
While final USDA yield numbers aren't in yet, it looks like 2017 wheat yields could rival the 2016 yields in portions of eastern Nebraska, based on state variety trials and extension educator reports. See the breakdowns by district.

Why Grow Winter Wheat in Eastern Nebraska?

August 31, 2017
The winter wheat varieties planted in eastern Nebraska today can yield upward of 140 bu/ac under good management and weather. If you haven't planted wheat in several years, consider today's advanced genetics and these other benefits from integrating wheat into your rotation.

Maps showing likelihood of yield deviations for rainfed corn at various sites.

2017 Corn Yield Forecasts as of Aug. 9

August 11, 2017
Corn yield forecasts for Nebraska sites indicate near-average to above average yields for most irrigated sites. There was much more yield variability for rainfed locations where three of the sites were forecast with a 50%-100% chance of below-normal yields and three were forecast for normal yields, while one was near average.

Probability of yield deviation for normal for irrigated corn, model ran July 18, 2017

2017 Corn Yield Forecasts as of July 18

July 19, 2017
Corn growth stages are estimated for 41 sites in 10 states and yields are estimated for select irrigated and rainfed sites, based on the Hybrid-Maize model and input from specialists and educators across a 10-state area as of July 18, 2017. The authors note that these early season yield forecasts vary widely, particularly for rainfed fields, and may change considerably by end of season.
