Hedging Your Average Crop Price Using Seasonals, Cory Walters, Richard K. Preston

Cornhusker Economics

In this article, we connect what the industry says and what producers say to improve the disconnect and the decision-making environment associated with hedging. We accomplish this by inspecting the distribution of producer prices with and without hedging in the fall as the distribution contains both yearly outcomes (producer concern) as well as the average outcome (another point of view). Computer models are used to lift the mystery surrounding the role of hedging. Computer models help understand complex processes, allowing for a better decision environment, leading to improved financial standing and stability. Our model reproduces the risk profile that individual …

Characterization Of Antiviral Immunity, Host Virus Interactions, And Toxicity Of Agrochemical Residues In The Western Honey Bee, Christopher Fellows

LSU Doctoral Dissertations

Honey bee colonies have perished at an alarming rate for over 15 years. Among the multitude of threats to bee health, virus infections and agrochemical exposure appear to be major drivers of colony loss. As virus infection is among the most damaging influences on bee health, we first investigated a putative target for antiviral immunity, termed K_ATP channels. We previously demonstrated that pharmacologically activating K_ATP channels induces the production of reactive oxygen species and increases survival during infection with Israeli Acute Paralysis Virus. Here, we demonstrate that K_ATP modulation and ROS induction reduce virus replication and enhance …

Home Tap Water In Nonmetropolitan Nebraska, Rebecca J. Vogt

Cornhusker Economics

Water is an important resource in Nebraska. Most of the drinking water in the state (85%) comes from groundwater sources. Public water sources are required to test their water to ensure it is safe. However, private wells are not subject to any safety or quality standards. Given that, what are the main sources of home tap water for rural Nebraskans? Do they test or treat their water? The 2022 Nebraska Rural Poll examined these questions.

Role Of Microorganisms In Horticulture To Improve Plant Quality, Domenico Prisa

Karbala International Journal of Modern Science

One of the most anticipated challenges in the field of agriculture is to ensure high production levels while limiting the use of environmentally harmful synthetic chemicals. One of the most interesting strategies to overcome this challenge is the exploitation of the interactions between soil microorganisms and plants which result in stimulating plants’ natural activity. The interactions among mycorrhiza, growth-promoting microorganisms and plants play a crucial role in soil fertility, biocontrol and protection. The use of mixed microbial products can simulate interactions between fungi and bacteria, realising all the benefits that can be obtained from these associations in terms of quantity …

Posters-at-the-Capitol

One of the most important factors regarding soil and plant health is nutrient availability and fertility. Of these two factors that were mentioned available potassium is a key component. With that being said we decided that it would be beneficial to see how potassium can be traced within the soil in various locations after fertilizer is applied. There were two parts to this experiment. Part one was taking soil core samples in order to obtain various soil properties such as soil organic matter, soil water holding capacity and bulk density and observe if these properties have any effect on the …

Seroprevalence And Titer Concentration Testing For Leptospirosis In Equine, Ashley Himmelsbaugh

Posters-at-the-Capitol

The most common best management practice used to combat diseases in horses is vaccination, which can decrease the incidence or severity of illness. However, the duration of immunity will vary for each vaccination and must be considered for revaccination purposes. Titer concentration, which evaluates antibodies in the blood, may be a helpful way of determining how long an animal has immunity to a disease. Leptospirosis, a zoonotic, bacterial disease, can result in uveitis, potentially leading to blindness, and abortion in mares. One serovar, Leptospirosis pomona (L. pomona), is associated with most cases of clinical disease in horses in North America. …

Linking Soil Properties to Originally Wooded and Afforested Areas

Matthew Laun, Ashton Crowe

Mentor: I. P. Handayani

Hutson School of Agriculture Murray State University, KY, USA

Abstract

Afforestation, adding an artificial forest to a piece of land that has been barren of trees for a significant amount of time, has some seriously huge impacts on the environment. These effects can be seen as an increase in the soil organic matter, a decrease in compaction, and enhancement of porosity. Therefore, the soil can support more diverse microbes and fungal communities leading to better micro and macro nutrient transfers between plants. This …

Foliar Application Of Acetic Acid And Effectiveness Against Drought At Different Time Points In Soybean (Glycine Max) Development, Miranda Rudolph, Megan Taylor Phd.

Posters-at-the-Capitol

Drought is arguably the most serious environmental factor affecting crop production today. A plant's response to drought stress is extremely complex, affecting numerous metabolic pathways that are all interconnected in their responses. Due to this complex nature, scientists do not fully understand the implications of different treatments and how they affect these processes. Acetic acid has been shown to improve plant growth and resistance to drought stress, but exactly how it accomplishes this is also unknown. Soybeans (Glycine max) are one of the most important crops worldwide and can suffer significant yield loss due to drought stress. As climate change …

Ecological Complexity And Avoiding Pest Resurgence: Intuitions From Mathematical Ecology, Theresa Ong, John H. Vandermeer

Dartmouth Scholarship

Pest resurgence is defined by a predictable increase in pests following declines resulting from the implementation of pest management practices. This phenomenon is notorious; familiar in biblical references to cyclical plagues of locust and discussions of pesticide treadmills, where pests resurge following the evolution of pesticide resistance. Targeted “silver-bullet” approaches, whether chemical, mechanical, biological, or genetic in nature, apply a reductionist lens toward the removal of a specific target pest, often ignoring ecological context, by application of said silver-bullet. In this review article, we cover how past and recent developments in theoretical ecology and complex systems dynamics provide a general …

Department of Agronomy and Horticulture: Faculty Publications

Environmental stresses such as drought, high salinity, and low temperature can adversely modulate the field crop’s ability by altering the morphological, physiological, and biochemical processes of the plants. It is estimated that about 50% + of the productivity of several crops is limited due to various types of abiotic stresses either presence alone or in combination (s). However, there are two ways plants can survive against these abiotic stresses; a) through management practices and b) through adaptive mechanisms to tolerate plants. These adaptive mechanisms of tolerant plants are mostly linked to their signalling transduction pathway, triggering the action of plant …

The Relation Between Wheat, Soybean, And Hemp Acreage: A Bayesian Time Series Analysis, Joohun Han, John N. Ng'ombe

Agricultural Economics and Agribusiness Faculty Publications and Presentations

The 2018 United States Farm Bill has opened the possibility for farmers to increase their profits through hemp cultivation. The literature suggests hemp has the potential to replace soybeans in soybean–wheat double-cropping because hemp shares key attributes of soybeans as a rotation crop (profitability, potential as an energy crop, and maintenance of soil fertility). Nonetheless, due to a short history of hemp cultivation in the USA, it is difficult to predict a time series relationship between hemp, soybean, and wheat through conventional approaches. In this article, we use Bayesian time series models and data from Statistics Canada and the Alberta …
