The Impacts Of Management Practices On Industrial Hemp Chemistry, Physiology, And Microbiome Ecology., Allison Marie Rietman

Electronic Theses and Dissertations

Agroecology incorporates ecology and agronomy to inform crop management. Industrial hemp (Cannabis sativa L.) is a prime system to investigate agroecological questions because it has only recently been authorized for commercial cultivation and its sensitivity to biotic and abiotic stressors is unresolved. Here, I investigate how some conventional management choices, including the application of fungicide, plastic mulch, and irrigation, impact the physiology, chemistry, and microbial ecology of industrial hemp. Overall, I found that industrial hemp can be both resilient and resistant to these stressors, an important development for the industry. In Chapter II, I tested the impacts of fungicide application …

Empowering Diversity: A Comprehensvie Approach To Minority Risk Management Education, Jahqethea Johnson

Applied Science Program: Theses

Federal programs are pivotal to the foundation of the United States agricultural sector. Program payments impact the economic well-being of agricultural producers, yet accessibility, outreach and education disparities remain prevalent among socially disadvantaged producer and agriculturists. From 2020-2024, an average of $21.7 billion dollars in federal agricultural payments have been paid to producers. Although federal funding historically supports commodity crops, livestock producers also depend on a distinct set of federal risk management programs, which are often less visible but pertinent for operational sustainability. There is a growing focus on the need for addressing disparities faced by socially disadvantaged producers and …

Assessing The Implicit Prices Of Health And Wellness Product Attributes In Pet Food: A Hedonic Analysis Approach, Lonnie Hobbs Jr., Andrew Anderson

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Here we examine product attributes present in dry dog food to show there exist potential price premiums and discounts associated with health and wellness attributes in dry dog food. The findings indicate price premiums are associated with attributes related to digestion and allergy care. Pricing discounts are found to be associated with immune support and dental attributes. The results of this study are anticipated to be a starting point for more sophisticated and dynamic analysis of pricing and willingness-to-pay studies in the pet food industry.

Maximizing Crop Production And Profitability Through Double Cropping Corn And Soybean Systems In South Carolina, Bennett Harrelson

All Dissertations

Profitability is critical for farm sustainability, efficiency, and longevity. Over the last decade, corn and soybean commodity prices have fluctuated considerably, and more recently, extreme increases in input prices have narrowed profit margins. Non-traditional cropping systems that can boost profit are becoming of interest to farmers in South Carolina, specifically double cropping soybean behind corn. In this scenario, corn is harvested at high moisture contents and followed by ultra-late planted soybean. However, prior research related to the agronomic production practices of double cropping corn and soybean is minimal. To develop best management practices for growers interested in double cropping corn …

Evaluating The Effects Of Co₂ And Uv-B On Sporobolus Virginicus (L.) Kunth Growth Under Open Top Chamber: A Comparison Of Silicon Nanoparticle-Treated And Untreated Plants, Suhaila Humaid Ablooshi

Theses

The study focused at how silicon nanoparticles (SiNPs; 50 mg/L) affected the growth, photosynthetic efficiency, and biochemical responses of the salt-tolerant halophyte Sporobolus virginicus in four different environments. They are control, high CO₂, UV-B radiation, and a mix of high CO₂ and UV-B. Plants that were treated with SiNPs showed big changes in their shape, such as more biomass, bigger leaf area, and better root systems in all conditions. The use of combined stress treatments caused a big increase in the levels of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids. As a result, that the plants were better at …

Sustainable Smart Farming Device With Leafit Adaptive Growth Technology, Saville Atkins, Anthony Iwejuo, Julian Pitts, Luis Mercado, Rachnicha Rojjhanarittikorn, Sandip Das, Hai Ho

Symposium of Student Scholars

For farmers, gardeners, and horticulture enthusiasts worldwide, one immutable reality is that maintaining a consistent physical presence to care for plants is not always feasible. In addition, different plants have unique needs for watering, nutrients, and environmental conditions to thrive. Failing to meet these specific needs can result in poor plant health, reduced yields, and inefficient resource usage. In this research project, we have designed and developed ‘LeaFit’ – a cutting-edge Internet of Things (IoT) device that offers a sophisticated and sustainable smart farming and gardening solution. Equipped with intelligent soil moisture, ambient temperature, humidity, and light sensors, LeaFit autonomously …

Where Is Your Crop Insurance Agent? Understanding The Geographical Distribution Of Agents, Cory Walters, Nathan Delay

Cornhusker Economics

Following the modifications to the Standard Reinsurance Agreement (SRA) in 2010, there was limited understanding of the impact of policy changes on agent availability. Our objective is to construct a model of the equilibrium supply of crop insurance agents and to test hypotheses regarding the factors influencing agent concentration, such as commissions, competition, and risk. We developed a theoretical equilibrium model of the federal crop insurance market, which encompasses three tiers: insurance companies, agents, and farmers. The model incorporates key features of the federal program, including government-set premiums and the stipulation that agents cannot refuse coverage or modify premiums for …

Responsiveness Of Desert Plant Dehydrin Genes In The Alleviation Of Abiotic Stresses, Mughair Abdul Aziz

Thesis/ Dissertation Defenses

Dehydrins (DHNs) are hydrophilic, glycine-rich proteins that accumulate in vegetative tissues of plants in response to abiotic stress and during the late stages of seed maturation. In desert plants, these proteins likely contribute to their specialized adaptation under extreme environmental conditions. To examine the genetic mechanisms underlying DHN associated abiotic stress tolerance in desert plants, this study aimed to isolate them and investigate the architectural features and functional mechanisms related to them. It involved cloning of full-length cDNA sequences of DHN encoding genes, PcDHN1, CcDHN1, PdDHN1, and PdDHN2, from three desert plants Prosopis cineraria, Citrulus colocynthis, and Phoenix datcylifera, followed …

Below-Ground Carbon Gradients Surrounding Saskatchewan's Native Agricultural Copses, Andrea V. Cline, Colin P. Laroque

Aspen Bibliography

As carbon markets develop, understanding the carbon storage capabilities of agricultural land is imperative to maximizing carbon storage. Ecosystems store two-thirds of their carbon below ground. Shrubland and shelterbelt carbon storage have been well documented in agricultural settings, yet little is known about the carbon stored under the native woody vegetation scattered across the Prairies. This study aims to be the first to quantify the below-ground carbon under and around these native trembling aspen (Populus tremuloides) copses in the Canadian Prairies. For this study, the leaf, fibric, humic layer (LFH) and soil samples up to 60cm were collected …

Floral Cues And Foraging Preferences In Various Species Of Wild Bumblebees, Olivia A. Dahl

The International Journal of Ecopsychology (IJE)

There are costs and benefits for plants and their pollinators. Bumblebees play a crucial role in the dynamic plant-pollinator system. Flowers co-evolved with insects, birds, and mammals toward mechanisms that benefited, described from a human perspective, both host and forager. Characteristics such color, olfactory cues, and temperature attract pollinators, with bumblebees showing preferences for blue and yellow flowers, as well as flowers that are warmer. This study aims to answer three questions: 1) How does floral temperature at different times of day predict visit length in bumblebees? 2) Does bumblebee size affect visit length? 3) Is there an interaction between …
