PAST SEMINARS

The Use of Novel, Reversed Physiological Phenotyping Methods in a Continuous High-Throughput Crop–Environment Characterization (Continuous G × E)

MENACHEM MOSHELION
Associate Professor, Plant Sciences and Genetics in Agriculture, The Robert H. Smith Faculty of Agriculture, Food and Environment, The Hebrew University of Jerusalem, Rehovot, Israel

Moshelion will discuss how this study demonstrates that continuous quantitative measurements of whole-plant (tomato) physiological traits can explain functional differences in their stomatal density and diurnal aperture, as well as their yield under field conditions. Idiotype lines have highly plastic stomatal-conductance, high ratio of abaxial-adaxial stomatal density and early daily aperture.

Collaborative Efforts to Diversify Nebraska Cropping Systems

ANDREA BASCHE
Assistant Professor of Cropping Systems, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Increasing diversity in Nebraska’s cropping systems can regenerate soil and improve profitability, critical goals for farmers and communities given market volatility and climate risks. This presentation will describe several collaborative projects underway to implement diversified management, as well as how such collaborative efforts are critical for the many goals we hope to achieve in our scientific fields and broader society.

Climate-smart Agriculture: Engaging One Health, Insects, Food and Water Security

GEORGINA BINGHAM
Research Associate Professor and Daugherty Water for Food Institute Faculty Fellow, Department of Entomology, University of Nebraska–Lincoln

Climate-related risks to health, livelihoods, food security, water supply, human security, and economic growth are projected to increase. In relation to entomology, this poses threats in the form of expansion of suitable habitats for many economically damaging insect pests’ species, particularly insects with vectoral capacity. This presentation will describe examples where the appearance and increase in abundance of these insects pose a threat to the US and global economy, agriculture, public and animal health.

From Discovery to Application in Ag Biotech: Lessons Learned Over 14+ Years in Industry

JASON NICHOLS
Principal Scientist, Syngenta Crop Protection, LLC

Translating discoveries into commercial products requires balancing business drivers with scientific possibilities. This presentation will provide an overview of the path from discovery to application for biotech trait development in the Ag industry and – with a focus on complex traits – highlight some of the challenges faced along the way and opportunities provided by the emergence of new technologies.

The Human Dimensions of Manureshed Management

GWENDWR MEREDITH
Assistant Professor and Social-Ecological Rangeland Scientist, School of Natural Resources, Department of Agronomy and Horticulture, Center for Resilience in Agricultural Working Landscapes, University of Nebraska–Lincoln

Manuresheds prioritize nutrient recycling between livestock and cropping systems but are dependent on collaboration of many actors. This seminar presents the current state of manureshed management, how can it be improved upon, and what social relationships need to be in place to facilitate this aspirational vision.

Interference Between Kentucky Bluegrass (Poa pratensis) and Yellow Nutsedge (Cyperus esculentus) in a Home Lawn Setting

LUQI LI
Lecturer, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

The presence of yellow nutsedge reduces turfgrass uniformity and visual quality in home lawns and playability on golf courses and athletic fields. Li found that an actively growing Kentucky bluegrass stand impedes tuber and shoot production of yellow nutsedge from 65% to 99% without using herbicide.

Weed Control in High Plains: Current Challenges and Future Outlook

VIPAN KUMAR
Assistant Professor of Weed Science, Agricultural Research Center, Kansas State University, Hays

The use of herbicides and herbicide-resistant (HR) crops have allowed to reduce or eliminate tillage for weed management, thereby benefitting soil and water conservation in the semi-arid High Plains. However, the widespread adoption of glyphosate-resistant crops, repetitive use of herbicides with the same mechanisms of action, and lack of diversity in production practices resulted in evolved resistance to herbicides in major cropland weed species, including horseweed, kochia, Palmer amaranth, common waterhemp, and Russian thistle. Managing HR weeds is complex and varies both within and between regions. Further complicating management is lack of community-wide concern and unified approach to management, lack of flexibility in government programs, and current commodity prices makes it difficult to change. This seminar will illustrate some of these challenges and will also highlight novel weed control strategies that may fit well in the no-till cropping systems of the High Plains for controlling HR weeds.

From World Cup Soccer to the Environment and Back Again: A Journey of Turfgrass Science

JOHN STIER
Associate Dean for Academic Programs and Professor, Herbert College of Agriculture, Department of Plant Sciences, University of Tennessee, Knoxville

Stier will present a story of how creating a unique playing field for World Cup soccer led to development of research and Extension programs to study grasses for sports and environmental stewardship, with impacts ranging from fertilizer rules to the 2026 World Cup.

Sustainability of Rice Production – Integrated Frameworks to Capture Synergies and Tradeoffs

CAMERON PITTELKOW
Associate Professor of Agronomy and Agroecosystems, Department of Plant Sciences, University of California, Davis

A major question facing global rice systems is the extent to which yield, resource use efficiency, and environmental footprint indicators can be simultaneously optimized to meet future food demand. This presentation will discuss recent advances in evaluating synergies and tradeoffs among multiple indicators to identify pathways for sustainability improvement in different rice production contexts.

A Coherent Measurement-Modeling Approach to Assess Soil Organic Matter Accrual in Agricultural Land

M. FRANCESCA COTRUFO
Professor of Soil and Crop Sciences, Department of Soil and Crop Sciences, Colorado State University, Fort Collins

Soil organic matter (SOM) provides many ecosystem services. Cotrufo will present her latest framework to conceptualize SOM structure, formation, and persistence, and a coherent measurement-modeling approach we implemented and use. She will provide examples of applications of our approach to quantify and forecast SOM changes under regenerative agriculture.

Is Site-Specific Management Leading Nebraska Growers Towards Higher Nitrogen Use Efficiency? 

LAILA PUNTEL
Assistant Professor of Soil Fertility and Precision Ag Specialist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

This seminar presents results about how different precision ag technologies for site-specific nitrogen management perform in corn and wheat cropping systems in Nebraska.
