PAST SEMINARS

Sept. 12, 2024

Pollen-mediated Gene Flow and Transfer of Herbicide Resistance Alleles

AMIT JHALA
Associate Department Head, Professor and Extension Weed Management Specialist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Managing herbicide-resistant weeds is a challenge for growers. Once herbicide-resistant weeds evolve, it can be spread by pollen, known as pollen-mediated gene flow. Reproductive biology differs markedly among weed species, as does the potential for gene flow. Pollen-mediated gene flow at a distance could allow the spread of rare herbicide resistance alleles and favor the evolution of multiple herbicide-resistant biotypes through the accumulation of resistance genes in an individual weed or weed population. Amit Jhala will discuss examples of economically important weeds such as waterhemp, palmer amaranth, and giant ragweed and crops such as corn and popcorn to demonstrate the role of pollen-mediated gene flow in transfer of herbicide-resistance alleles.

Cultivating Collaboration: Incorporating Social Science for Innovative Approaches to Agriculture and Wildlife Research

BROOKE MCWHERTER
Research Assistant Professor and Natural Resource Social Scientist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Wicked challenges in natural resource management demand more than just traditional solutions — they require a collaborative, multi-disciplinary approach. This presentation will showcase how integrating social science with environmental and agricultural research enhances our ability to address these complex issues. Through current and ongoing projects, Brooke McWherter will discuss the development of collaborative research, share key social science findings, and outline her vision for future work at the University of Nebraska–Lincoln.

Sept. 26, 2024

Genetic Basis of Grain Yield and Quality under Heat Stress in Rice

ANIL CHANDRAN
Ph.D., Research Technologist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Heat stress during the grain-filling period has a detrimental effect on rice yield and quality. The development of heat-resilient cultivars could help address this issue if tolerant alleles can be identified and incorporated into the germplasm. This presentation will focus on the research conducted to understand the genetic basis of grain yield and quality under heat stress in rice.

Oct. 3, 2024

Design Thinking for Specialty Crop Innovations in the Field and Classroom

SAM WORTMAN
Associate Professor and Environmental Horticulturist, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Design thinking for innovation is a systematic, iterative, and creative process for solving problems and developing new products, practices, and services in plant and landscape systems. In this seminar, Sam Wortman will share an example of design thinking for innovation in his research, leading to commercialization of the RootThru Weed Barrier. He will also discuss classroom strategies for engaging students in design thinking through the creation of their own innovations.

Making the Case for Manure to Improve and Enhance Natural Resources

AMY SCHMIDT
Professor and Livestock Bioenvironmental Engineer, Department of Biological Systems Engineering, University of Nebraska–Lincoln

Using manure to fertilize crops is a practice as old as time. However, as agricultural production systems have become more specialized (e.g., less integrated), reliance on inorganic fertilizers has increased while manure has increasingly become viewed as an environmental pollutant and nuisance. When properly managed, though, manure serves as a valuable fertilizer and soil amendment to provide essential crop nutrients and support the living ecosystem in soil. This presentation will explore the role of soil health in achieving food security, natural resource protection, and resilience to climate change, and the value of recycling locally available manure as a cropping system input prior to importing inorganic fertilizers.

Oct. 17, 2024
 

JESSE BELL seminar

Droughts, Agriculture, and Public Health

JESSE BELL
Claire M. Hubbard Professor of Water, Climate and Health, Department of Environmental, Agricultural, and Occupational Health, University of Nebraska Medical Center, School of Natural Resources, University of Nebraska–Lincoln; Director of Water, Climate, and Health Program at UNMC; Director of Water, Climate and Health at the Daugherty Water for Food Global Institute at the University of Nebraska
 

The mission of the Water, Climate and Health programs at the University of Nebraska is to develop interdisciplinary research, education and collaborative solutions to public health challenges associated with environmental issues in Nebraska and around the world. As the founding director, Jesse Bell has helped grow these programs to over 25 faculty, staff, and students. In this seminar, Bell will discuss how human and natural processes are connected to changes in the environment and climate.

Oct. 24, 2024
 

VLADIMIR TORRES-RODRIGUEZ seminar

The Use of Gene Expression to Predict Gene Function in Maize and Sorghum

VLADIMIR TORRES-RODRIGUEZ
Research Assistant Professor, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
 

Vladimir Torres-Rodrigues joined the James Schnable lab in October 2021 as a postdoctoral scholar, since then he has been working with quantitative genetic techniques to predict genes associated with a phenotype. He became a Research Assistant Professor this July.

Oct. 31, 2024
 

GUILLERMO BALBOA seminar

Assessing and Advancing Digital Agriculture in Nebraska

GUILLERMO BALBOA
Research Assistant Professor in Nutrient Management and Digital Agriculture, Department of Agronomy and Horticulture, University of Nebraska–Lincoln

Nebraska is a leader in adopting Digital Agriculture (DA) tools across the U.S. This seminar will assess the state of DA in Nebraska and highlight ongoing efforts to develop, evaluate, and promote tools and technologies that address the state’s agricultural challenges.

Nov. 7, 2024
 

DESMOND LAYNE seminar

The FoodU Program at Auburn University

DESMOND LAYNE
Department Head and Professor, Department of Horticulture, Auburn University

FoodU provides Auburn University students with transformational food system learning experiences as they grow hyperlocal fruits, vegetables, herbs and flowers to support consumption and utilization in Campus Dining, the Culinary Sciences program and in two on-campus restaurants. Produce is grown outdoors in raised beds, in greenhouses, vertical farms and on a rooftop. Desmond Layne will discuss program highlights, best practices and challenges.

Nov. 14, 2024
 

MITCH STEPHENSON seminar

Cattle Grazing and Conservation: Rangeland Research at the Gudmundsen Sandhills Lab and Barta Brothers Ranch

MITCH STEPHENSON
Associate Professor and Rangeland Management Specialist, Department of Agronomy and Horticulture, Associate Director of the Panhandle Research, Extension and Education Center, University of Nebraska–Lincoln

The Gudmundsen Sandhills Laboratory and Barta Brothers Ranch have provided the University of Nebraska–Lincoln a valuable working landscape in the Sandhills to conduct rangeland research. This presentation will highlight past and present rangeland research at these locations.

Nov. 21, 2024
 

KYLE KOCAK seminar

Technology Application in Soybean Breeding

KYLE KOCAK
Research Scientist, Corteva Agriscience

New technology has fundamentally changed plant breeding programs inside Corteva. Identifying and leveraging technology is a key component of running a modern soybean breeding program. Kyle Kocak will discuss some examples of how genetic gain can be accelerated by successfully applying new technology to plant breeding.
