Extension Cropping Systems Agronomist

Research & Extension Roles

Elmore's vision for his applied crop production research and extension work at the University of Nebraska–Lincoln is to maintain or increase crop production profitability and water use efficiency by seeking and demonstrating environmentally sound production practices. His mission is to research, develop, teach and extend timely and pertinent crop management information for farmers, agribusiness, Extension personnel and graduate and undergraduate students. To that end, his research program focuses on production practices that increase profit through optimizing or maximizing yield and water use. Earlier research projects include: effects of previous hybrid in corn following corn systems; dry matter and nutrient accumulation of modern and historical corn hybrids, effects of corn planting dates, row spacing, plant population responses, as well as the impact of plant to plant variability. A major accomplishment while serving at Iowa State Univ. was the publication of Abendroth et al. 2011, Corn Growth and Development, Iowa State Univ. Extension PMR 1009. At Nebraska, he co-leads with Humberto Blanco and several other colleagues a new cover crop research project supported by the Nebraska Soybean Board and the Nebraska Corn Board.
