Soybean Response to Micro-Rates of Dicamba and 2,4-D
STEVAN KNEZEVIC
Professor of Integrated Weed Management, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Off-target movement of dicamba and 2,4-D, a concern with the introduction of dicamba-tolerant (DT) and 2,4-D-tolerant (Enlist) soybeans in North America and elsewhere. Therefore, field studies were being conducted in Nebraska to evaluate glyphosate-tolerant (GT) soybean response to micro-rates (0, 1/1000th, 1/500th, 1/100th, 1/50th, 1/10th) of the label rates of dicamba and 2,4-D applied at V2, V7/R1 and R2 soybean growth stages. Both herbicides negatively influenced multiple growth parameters of GT soybeans including visual injury, plant height, physiological maturity as well as yield and yield components. In all cases injuries and yield reductions from dicamba were significantly higher than those from 2,4-D for the same rate.
Applications of Remote Sensing in Monitoring Ecosystem Function and Biodiversity
RAN WANG
Research Assistant Professor and Image Processing Specialist, School of Natural Resources, University of Nebraska–Lincoln
Remote sensing offers novel approaches to investigating terrestrial ecosystem responses to the changing environment. Wang will discuss how we can use the cutting-edge technologies on campus, including imaging spectrometry and fluorometry, to monitor plant photosynthesis, biodiversity and ecosystem function.
Industrial Hemp Research at West Central Research, Extension and Education Center
MILOS ZARIC
Graduate Research Assistant, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Understanding the potential pros and cons of industrial hemp production can reduce the risk for local growers interested in starting or expanding their production efforts. This seminar will provide insights into industrial hemp research about (1) the sensitivity to the physical drift of herbicides registered for use in corn and/or soybean and (2) the evaluation of crop tolerance and the possibilities for diversification of Group 1 herbicides.
National and International Agricultural Genome-to-Phenome
JENNIFER CLARKE
Professor of Statistics and Food Science and Technology; Director, Quantitative Life Sciences Initiative, University of Nebraska–Lincoln
Clarke will cover several national and international projects to advance genome-to-phenome research in agricultural contexts. These projects include the plant, animal and data sciences. The presentation will focus on USDA Agricultural Genome-to-Phenome Initiative (AG2PI), the National and International Plant Phenotyping Networks, and the USDA National Agricultural Producers Data Cooperative (NAPDC).
Interseeding Cover Crops into Corn and Soybeans: What We’ve Learned
JENNY REES
Nebraska Extension Educator, University of Nebraska–Lincoln
More farmers are seeking alternative ways to reduce inputs such as nitrogen and herbicides. Sixteen site-years of data will be shared where cover crops were interseeded into V3-5 corn and VC-V2 soybean. Future directions will also be shared.
Soybean Tolerance to Off-Target Dicamba
CAIO CANELLA VIEIRA
Assistant Professor of Soybean Breeding, Department of Crop, Soil and Environmental Sciences, University of Arkansas
The development of dicamba-tolerant soybean and cotton was followed by massive reports of off-target damage across the United States. This research aimed to estimate yield losses associated with off-target damage in over 550 soybean breeding lines, as well as identify genomic regions regulating tolerance in genetically diverse accessions.
Experimentation on Nebraska Farms for Sustaining Soil Health Management
FERNANDA KRUPEK
Graduate Research Assistant and Ph.D. Candidate, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
Cover crops have been promoted in Midwestern U.S. agroecosystems as a way to meet several soil health goals. Using a range of scientific methods, from lab-based experiments to on-farm research to interviews, Fernanda will discuss her doctoral studies exploring soil, crop and human dimension considerations to design farming systems in Nebraska for improved soil health.
Novel Technologies for Monitoring Field and Farm-scale Greenhouse Gas Emissions
EDUARDO SANTOS
Associate Professor of Micrometeorology, Department of Agronomy, Kansas State University
The most critical agricultural challenge is to feed a growing population while minimizing the environmental footprint of crop and livestock production. The creation of a new generation of agricultural sensors will provide accurate gas emission data at relevant times and space to identify practices to reduce greenhouse gas emissions.
Keeping Extension Relevant: What Might the Future of Extension Look Like?
CHRIS PROCTOR
Weed Science Extension Educator, Department of Agronomy and Horticulture, University of Nebraska–Lincoln
As extension audiences change how can we continue to help provide relevant solutions to stakeholder challenge? This seminar will explore things we are doing well in extension and how we may need to adapt to meet stakeholder needs both now and in the future.
The ‘omics of Organic Matter – Using Molecular Tools to Decipher SOC Persistence in a Changing World
A. PEYTON SMITH
Assistant Professor of Soil Carbon Dynamics, Department of Soil and Crop Sciences, College of Agriculture and Life Sciences, Texas A&M University
Uncertainties in predicting the soil’s response to global change arise from the often complex and dynamic interactions between biological, geochemical and physical processes occurring below ground. This talk will explore how microbial and molecular tools can reveal fundamental mechanisms that regulate the persistence of organic matter in soils.
Robotic Tools for Climate-Smart Agriculture
SANTOSH PITLA
Associate Professor of Advanced Machinery Systems, Biological Systems Engineering, University of Nebraska–Lincoln
Transitioning to climate-smart agriculture requires a paradigm shift in how we manage crop inputs and natural resources. Robotics, automation and AI-enabled autonomous systems offer promise for improving productivity of field operations. This talk focuses on the development of multi-robot ground and aerial robotic systems and their potential use cases for deploying climate-smart agricultural practices.
Debugging Misconceptions about Arthropods
DOUG GOLICK
Associate Professor, Department of Entomology, University of Nebraska–Lincoln
The United States public has profound misconceptions about insects and terrestrial arthropods. These misconceptions are often learned at an early age and may be linked to poor practices like the overuse of pesticides and unnecessary fear and disgust of insects. Golick will share some of his lab’s research on arthropod misconceptions and share teaching and interventions that have been developed to improve knowledge and conservation practices about insects. He will also share how you can scale up learners’ understanding of larger complex issues through “tiny” misunderstandings about arthropods.
