Some Economic Implications Of The Covid-19 Pandemic In Nebraska, 2020 University of Nebraska-Lincoln
Some Economic Implications Of The Covid-19 Pandemic In Nebraska, John C. Beghin
It is now clear that the spread, mortality and morbidity impacts of the coronavirus pandemic are sizeable but extremely heterogeneous across multiple dimensions. Geography shows that places with lower human con-centrations (urban/rural divide) and away from main travel axes, such as major interstate highways and in-ternational airports, have a lower incidence of cases. Large urban centers with high human concentrations have been much disproportionally affected and with much higher mortality rates. Age and health status are equally important. Mortality increases dramatically for people 60 years old and older. People with comorbidi-ties (cardiovascular, obesity, diabetes, and others) are much more ...

Size And Scope Of Carbon County Agriculture 2019, Ryan Feuz, Ryan Larsen, Steven Price
All Current Publications
Carbon County is located south of Duchesne and Wasatch counties in east-central Utah. Along with Emery County to the south, it is often referred to as Utah’s Castle Country. The county became industrialized very early after statehood with the arrival of the railroads and discovery of many coal beds for which the county is named. It is also a large producer of natural gas within the state. Its primary economic base today comes from regional services, retail, tourism, recreation and resource extraction. As of 2017, the population was estimated at 20,295. Price is the largest city and county ...
Reaction Of Tepary Beans To Eight Virulent Races Of The Rust Pathogen That Overcomes All Known Common Bean Rust Resistance Genes, Santos Barrera Lemus, Prabin Tamang, Carlos A. Urrea, Marcial A. Pastor-Corrales
Theses, Dissertations, and Student Research in Agronomy and Horticulture
Bean rust, caused by Uromyces appendiculatus, is a major disease of common and snap bean (Phaseolus vulgaris) worldwide (Stavely, 1984). Although host resistance is an important component of rust management (Mmbaga et al., 1996), populations of the rust pathogen comprise an extensive and shifting virulence diversity that could render susceptible all known rust resistance genes in common bean. Conversely, it has been suggested that certain tepary bean (Phaseolus acutifolius) accessions are broadly resistant to bean rust (Miklas & Stavely, 1998). The objectives of this study were to verify if tepary beans are resistant to eight races of the bean rust pathogen ...
The Growing Threat Of Agroterrorism And Strategies For Agricultural Defense, 2020 Liberty University
The Growing Threat Of Agroterrorism And Strategies For Agricultural Defense, Alyssa Forrest
Senior Honors Theses
Due to the dynamic nature of human conflict, non-traditional terror tactics have evolved to undermine the socioeconomic stability of targeted societies. Considering the landscape in which terrorists operate, emphasis on more subversive methods of biological terror have become prominent in recent decades. Agroterrorism, or the use of plant pathogens to infect a nation’s cultivated crops, is an emerging topic due to its threat to global food security and economic stability. Although emergency preparedness objectives have been enacted at national, state, and even local levels, preemptive measures can no longer remain the sole responsibility of intelligence and law enforcement agencies ...

Covid-19, Farm Survival And Decision Making, 2020 University of Nebraska-Lincoln
Covid-19, Farm Survival And Decision Making, Cory Walters, Jessica Groskopf, Richard Preston
COVID-19 is causing us to experience events that have always been possible, just not yet observed. For farmers these events may have a big negative financial impact, or they may not. The impact on each individual farm has to do with how that individual farm has prepared for rare financially devastating events. Preparing for unseen events represents a logical approach. We call this approach stress testing. Just because you have not seen an event, it does not mean it does not exist. Or said another way, absence of evidence is not evidence of absence. In this article, we discuss how ...

Mechanisms Of Silencing Suppression By A Polerovirus P0 Protein, 2020 University of Nebraska - Lincoln
Mechanisms Of Silencing Suppression By A Polerovirus P0 Protein, Natalie Holste, Hernan Garcia-Ruiz
Posters & Presentations in Biological Sciences
Maize lethal necrosis is an intense viral disease spreading across sub-Saharan Africa. Maize is the staple crop grown in sub-Saharan Africa, but most crops infected with maize lethal necrosis will not survive to harvest. This causes immense economic hardship and starvation within the population. Maize lethal necrosis consists of a combination of two viruses, Maize chlorotic mottle virus (MCMV) and a virus from the genus potyvirus. In a recent study, a Maize yellow dwarf virus-RMV (MYDV-RMV)-like polerovirus, was repeatedly detected in plants with maize lethal necrosis. Poleroviruses have a silencing suppressor, P0 protein, and the mechanism of suppression is ...

UCARE Research Products
The CGIAR reports that around 40% of global crop yield variability is explained by climate. While global food consumption is expected to soar in 2050, the impact of climate change accounts for approximately 5% decrease in crop productivity. FAO estimates a 60% increase in global food demand by 2050, with global population reaching 9.8 billions. Sustainable soil management was also noted to boost agricultural food production by 58%. The evaluation of the impact of different management practices on dynamic soil properties was conducted on Geary silty clay loam, 3 to 7 %, eroded soils, which are mainly used for crop ...

The Effect Of Gap Spacing Between Solar Panel Clusters On Crop Biomass Yields, Nutrients, And The Microenvironment In A Dual-Use Agrivoltaic System, 2020 University of Massachusetts Amherst
The Effect Of Gap Spacing Between Solar Panel Clusters On Crop Biomass Yields, Nutrients, And The Microenvironment In A Dual-Use Agrivoltaic System, Kristen Oleskewicz
Agrivoltaic (AV) systems are dual-use land systems that consist of elevated solar panels with crops grown underneath. They offer a solution to the increasing demand for food production and clean renewable energy. The main concern regarding AV systems is the reduced availability of light to crops below the panels. Research to date shows that AV systems are quite productive with total energy and crop production exceeding the outputs of either solar farms or crop production alone. Research also shows that solar panels affect the microenvironment below the panels. The research on AV systems so far considers altering panel density to ...
Simulating Southern Rust Damage In Corn Through Defoliation, 2020 Louisiana State University and Agricultural and Mechanical College
Simulating Southern Rust Damage In Corn Through Defoliation, Michael Keith Shannon
LSU Master's Theses
The importance of leaf area to corn for grain production beginning at silking is well documented. However, being able to predict yield loss due to defoliators such as foliar plant diseases and insects that progressively increase in defoliation over time has been difficult to quantify. To address this issue, a leaf removal study was conducted at the Dean Lee Research and Extension Center located near Alexandria, Louisiana in 2017 and 2018. Two hybrids, differing in relative maturity were evaluated in this study. An early maturing hybrid (108 days in 2017 and 107 days in 2018) and a later maturing hybrid ...

Preemergence Herbicide Application Timings: Pros And Cons, Robert G. Hartzler, Meaghan J. B. Anderson, Prashant Jha
Integrated Crop Management News
Preemergence herbicides are the foundation of herbicide-based weed management systems, and effective use of these products is essential to protect crop yields and reduce selection pressure for herbicide resistant weeds. In a perfect world, applying preemergence herbicides immediately after planting would provide the greatest likelihood of maximum performance, but equipment and labor availability limit many farms from using this approach. This article will provide a brief overview of the pros and cons of different application strategies
