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.

The end-of-season corn yield report finds that high temperatures during vegetative stages had little impact on forecasted yield potential. This is the final article in the series looking at simulated crop stages and yield forecasts for 41 locations across the US Corn Belt.
A research project in eastern Nebraska is evaluating a double crop production system as a potential alternative to the traditional corn/soybean rotation. Following an early season crop of yellow field peas, short-season crops (corn, soybean, grain sorghum, millet and sunflower) and annual forages (forage sorghum and sorghum-Sudangrass) were planted.
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.
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.
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.
There are now five structurally different growth regulator herbicides, each of which affects plant growth differently. Understanding the differences can help you better identify the cause when you find damage in your field.
