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.

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.

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.

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.

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.

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.
