Professor, UNL Agronomy and Horticulture
Conjugating amino acids to jasmonic and indole-3-acetic acids is critical for proper regulation of plant growth, development and defense response. Recent study of the enzyme family responsible for conjugation will be highlighted to illustrate their surprisingly diverse roles in activating, inactivating and changing the biological function of these signal molecules.
Assistant Professor, UNL Statistics
Response Surface Methodology (RSM) is a strategy to aid accurate predictions for genomic prediction (GP) methods and will be described in this seminar. RSM will be illustrated with a simulated example on double haploid lines with factors such as the number of progeny, markers, QTLs, genetic architecture of the population, and heritability.
Associate Professor, UNL Agronomy and Horticulture
The identification, development, and evaluation of agronomically sound, environmentally acceptable and economically viable forage-crop-livestock systems is fundamental to agricultural diversification. Our efforts towards developing such systems will be described.

Assistant Director, Innovative Instructional Design, UNL Online & Distance Education
Faculty know writing improves critical thinking and that writing skills are essential for future success, but find giving feedback on and grading long written work, such as term papers, to be prohibitively time consumptive. In this seminar session, we will look at four assessment techniques making use of short written work that improve high-level learning such as analytic thinking and synthesis, but which also improve writing skills and give faculty keen insight into students’ understanding of course concepts.
Dean and Director, Nebraska Extension
Advancement in teaching and learning methods for Extension professionals is evolving the way we engage Nebraskans. Also, the roles of Extension Educators and Specialists are evolving as we think about collaboration and accomplishment. Our opportunity in this age of digital engagement can strengthen our relationships with learners in ways that enhance outcomes. This will be an interactive seminar on modern Extension methods and applications.
Science Literacy Specialist and Assistant Professor, UNL Biological Systems Engineering
The IANR Science Literacy Initiative fosters a society with an enhanced capacity, for both individuals and groups to make effective decisions grounded in STEM-informed analyses of complex, real-world challenges. In this presentation Jenny Keshwani will describe several projects that use the engineering design process to promote science literacy.
Associate Professor, UNL Agronomy and Horticulture and Center for Plant Science Innovation
This seminar will describe the generation and characterization of mutants for identification of modifier genes in the high-lysine Quality Protein Maize variant. David Holding will also describe our mutagenesis, mapping and candidate gene pipeline for general functional genomics of seed development and mineral homeostasis in maize. Finally, he will describe a gene editing approach for improving sorghum digestibility.
Professor, UNL Agronomy and Horticulture, Visiting Professor of Agroecology, Norwegian University Life Sciences
Agroecology has emerged as an alternative and holistic approach to systems thinking in education, applying phenomenology and practical experience along with science as valuable foundations for learning. Working with farmers and food system professionals, student teams use open-ended case studies to pursue education for responsible action. Agroecology explores production, economic, environmental, and social dimensions of food systems, with innovative programs in Norway, U.S. Midwest, Sweden, Uganda, Ethiopia, and India, as well as many countries in Latin America.
Assistant Extension Educator, Weed Management, UNL Agronomy and Horticulture
The importance of research data to inform extension outreach is widely recognized. Nevertheless, one of the challenges facing extension professionals is effectively translating research data into impactful information. While this challenge is not new, this seminar will consider how we might continue to make progress on enhancing the impact of extension related research outcomes.
Research Agronomist, USDA-ARS
Corn residue or stover has been used for decades for grazing, livestock bedding, or harvested as supplemental feed for beef and non-lactating dairy cattle. There are multiple advantages to utilizing corn residue, including managing residue quantity in high production fields, supplemental revenue, and a simple, cost-effective method of integrating crop-livestock systems. In addition to its use for the livestock industry, corn residue is the primary feedstock for a fledgling cellulosic bioenergy industry. This seminar will look at current USDA-ARS research on corn residue utilization in Nebraska and in the Corn Belt Region.

Professor & Charles R. Parencia Chair in Cotton Entomology, Department of Entomology, Texas A&M University
Beneficial fungal endophytes can confer protection to plants from a variety of stressors and improve yields in major agricultural crops. This talk will highlight progress in the targeted application of fungal endophytes in cultivated cotton (Gossypium hirsutum) to mediate resistance to multiple stressors including insects, nematodes and drought, with significant positive impacts on plant performance and yields in the field.
Crop Biomechanics Laboratory, Assistant Professor of Engineering, New York University Abu Dhabi
Douglas Cook’s research focuses on crop biomechanics. The aim of his research is to quantify factors than are predictive of crop stalk strength. To accomplish this goal, he has worked closely with academic and industry scientists to characterize stalk failure, design stalk testing protocols, perform stalk strength experiments, assess stalk geometry, design devices for measuring stalk strength and record the sounds produced by growing corn. His research has been supported by grants from the U.S. National Science Foundation, the U.S. Department of Agriculture and industry. His research findings have been published in fields as diverse as acoustics, biomechanics, biomedical engineering, agronomy, medicine and botany. Cook earned a bachelor’s degree in mechanical engineering from Utah State along with minors in mathematics and Mandarin Chinese. He also received a master’s and doctoral degree in mechanical engineering from Purdue University.
Assembling soil microbiomes that modify plant traits
Assistant Professor, Cornell University
The soil surrounding roots holds a diverse array of microorganisms that can influence plant development. Microbial experimental systems can be used to tease apart components of the microbiome responsible for trait development in plants. I will be discussing the concept of assembling microbiomes that alter specific plant traits, in hopes of developing microbial technologies that enhance agricultural sustainability.
Professor, Weed Management – Field Crops, University of Guelph Ridgetown Campus, Ontario
Peter Sikkema’s research focuses on the development of precision weed management programs in corn, soybean, edible bean and cereals to improve the level of weed control, reduce crop injury, increase crop yield and maximize net returns to Ontario producers. Recent or current projects include crop tolerance and weed management in corn; soybean, edible beans and cereals; benefits of two-pass weed management strategies in Roundup Ready corn and soybean; control of problem weeds in corn, soybean and wheat; surveys on the distribution of glyphosate-resistant (GR) weeds in Ontario; and development of strategies for the control of GR weeds in Ontario. There are four weed species with confirmed resistance to glyphosate in Ontario, among the 37 globally known GR weeds. These include giant ragweed (seed collected in 2008), Canada fleabane (seed collected in 2010), common ragweed (seed collected in 2011) and waterhemp (seed collected in 2014). Surveys show that over time the number of locations is increasing and GR weeds are found over a wider geographical area. Field trials were established at various sites with GR giant ragweed, Canada fleabane, common ragweed and waterhemp in 2010–2016 to evaluate control options in corn, soybean and wheat. Sikkema will speak about the importance of implementing weed management practices that limit the selection of additional GR weeds. Long-term approaches to weed management will be presented.
