Addressing The Trade-Offs Of Pest Protective Row Covers For Integrated Pest Management In Vegetable Production, Kathleen Fiske

Theses and Dissertations--Entomology

The success of many integrated pest management (IPM) strategies is limited by trade-offs with economic, cultural, and environmental factors. While some IPM strategies reduce pests, they may harm pollinators, reduce the efficiency of weed or disease management, or may increase costs relative to revenue. Pest protective row covers, in the form of fine-mesh netting (referred to as mesotunnels), are an effective alternative to pesticide use, but they are not without their challenges. While row covers exclude insect pests and the pathogens they vector, it is unknown how well non-vectored diseases can be managed underneath the row cover. The exclusion of …

Which Factors Influence Consumer Organic Specialty Bakery Product Taste Ratings?, Tatiana Drugova, Kynda R. Curtis

All Current Publications

In this fact sheet, we compare consumer taste ratings for organic and conventional specialty bakery products and analyze what factors explain the differences. These products are typically consumed for pleasure and are more expensive than mainstream baked goods. However, consumers have high quality expectations, including taste, which may be an issue if not satisfactory. Understanding factors that impact consumer taste rating for organic specialty bakery products can help identify what might be done to improve taste perceptions/expectations and the success of organic specialty bakery/pastry products.

Vermicompost Versus Traditional Compost Amendments Leads To Different Soil Health Outcomes In A Mediterranean Vineyard, Elizabeth L. Luck

Master of Science in Environmental Sciences and Management Projects

Compost application has become a common practice in vineyard management to increase soil and crop health, however, the environmental externalities such as greenhouse gas emissions (GHG) from cropping systems that utilize organic fertilizers, such as compost, is uncertain. Vermicompost, which is compost created through the digestion of organic matter by earthworms, and its related ‘extract’ are commonly thought to provide more benefits for soil and crop health compared to standard compost. However, organic fertilizers such as vermicompost, vermicompost extract, and compost have not been compared in their effects on soil health in Mediterranean vineyards. In this two-year study, I assessed …

Responses Of Soil Heterotrophic Respiration And Microbial Biomass To Organic And Conventional Production Systems, Kripa Dhakal, Madhav Parajuli, Siyang Jian, Jianwei Li, Dilip Nandwani

Agricultural and Environmental Sciences Faculty Research

The effects of organic and conventional production systems on crop productivity have been greatly explored, but their effects on soil microbial processes were often neglected. A comparative field study of organic and conventional production systems was conducted at the Tennessee State University research farm to determine soil heterotrophic respiration and microbial biomass carbon. Leafy green vegetables were grown in a conventional production system in an open field, and they were grown in an organic production system, using three different row covers (agribon cloth, insect net, and plastic), and in an open field. Soil samples (0-15cm) were collected from the two …

The Relationship Between Food Retailers And Distributors, Madison Seigler, Julia Anderson, Aidan Morton, Cassandra Williams, Victoria Bloomgren, Jacob Tutty

Undergraduate Theses, Professional Papers, and Capstone Artifacts

Our understanding of the science of anthropogenic climate change and its immediate and indirect impacts has grown within the last decade.Alongside anincrease in concern for the inequities within the industrialized food system, climate change is impacting agriculture and the communities that depend on it in myriad ways. These challenges have catalyzed investment in sustainable agriculture, “eat local” food movements, and rethinking of all aspects of food systems, including consumers, producers, retailers, and distributors. The body of literature on food systems primarily focuses on the connection between consumers and retailers; however, there is a notable absence of literature on the relationships …

Comparing Organic And Conventional Yield Responses To Climate Variations, Joost Wilken Meyer

Graduate Theses and Dissertations

This thesis compares the responses of organic yields and conventional yields towards climate variations. To achieve this objective, weather variables such as growing season weather conditions (average temperature, precipitation, cloud cover, relative humidity, drought index), weather anomalies, the occurrence of severe or extreme droughts and excessive rainfalls, are combined with 23 data sets gathered from previous studies that compare organic and conventional yields from the same location and time periods. To narrow the scope, the thesis focuses on soybean, maize, and wheat production in Europe and North America. Study-level fixed-effects models are used to control for any time-invariant factors such …

Is There Room In The United States Diet For Goat Meat? Analysis Of The 2019 National Goat Meat Survey, Everett Marcus Martin

MSU Graduate Theses

Demand for goat meat has steadily increased in the past decade, but few studies have been conducted addressing goat meat attributes and demographic factors on consumers’ willingness to buy goat meat products. Analyzing a national consumer survey on goat meat preference, a logit modeling is used addressing factors affecting willingness to buy three goat meat products: grass-fed, locally grown, and organically raised. Results indicate that quality and freshness attribute characteristics significantly affect consumer willingness to buy grass-fed, organic, and locally grown goat meat.

Mineral Nutrition In Broilers: Where Are We At?, Rick Kleyn, Mariana Ciacciariello

Proceedings of the Arkansas Nutrition Conference

Mineral nutrition remains an essential consideration for broiler nutritionists. The complex interactions between different minerals sources, other ingredients, and the broiler itself, coupled with their relatively low costs, have led to the current status of elevated levels of minerals in broiler diets. New perspectives on sustainability have brought about a rethink of the way we formulate practical diets. There are considerable opportunities for reducing macro minerals such as calcium and phosphorus, particularly for older birds. Our understanding of attaining an ideal dietary cation-anion balance is confused by the lack of clarity in measuring the balance and the bird’s ability to …

Evaluation Of Nutrient Solutions Produced From Aqueous Extracts And Decomposition Products Of Organic Waste Materials On The Plant Growth Performance In Hydroponics, Noura Said Al Nuaimi Said Al Nuaimi

Theses

Hydroponic plant production involves the cultivation of plants in absence of soil. In this system, the supply of the plant root with water and nutritional elements occurs via a nutrient solution made of inorganic salts. Hydroponic plant cultivation often achieves higher yields, water use efficiencies and quality of crops compared with soil production. In addition, it renders the farming system independent from soil properties. However, the currently available systems rely on the steady input of non-renewable inorganic salts. Unlike soil-based systems, hydroponics, so far, do not offer feasible opportunities for recycling nutritional elements from within crop residues or organic waste …

Forage Species Selection For Transitional Organic Production In The Southeastern United States, Jonathan Kubesch

Masters Theses

Despite the vast production markets for forage and organic products nationally, so far limited work has been done to develop organic forages specifically for Middle Tennessee or the mid-South in general. The present organic research field focuses on vegetable and grain production; however, forage production offers an easier transition for producers moving into certified organic agriculture. The present study seeks to evaluate several forage blends for optimizing forage production under low-input transitional organic conditions. Ideally a forage system could be tailored to the beef cattle operations of Middle Tennessee, the dominant forage consumption market in this region of the mid-South. …

Alternative Production Practices And The Role Of Consumer Choice: Willingness-To-Pay Analyses, Amanda P. Wecker

MSU Graduate Theses

Production choice is often viewed as driven by the resources and methods known to the producers. However, recent discussions focus on the other factors leading to production choice such as consumer preference, measured by factors such as willingness to pay (Tait, Saunders, Guenther, and Rutherford, 2016). This study evaluates the role of diet preference and age in driving a consumer’s willingness to pay for food produced with specific method. The data analyzed are from the 2016 U.S. Lifestyles of Health and Sustainability (LOHAS) Consumer survey. A total of 1042 individuals were asked whether they were willing to pay 10% more …

Changes Of Some Horticultural Characteristics In Jujube (Ziziphus Jujube Mill.) Fruit At Different Ripening Stages, Hakan Keles

Turkish Journal of Agriculture and Forestry

In this study, changes in some horticultural characteristics of jujube fruits at two ripening stages were investigated. The ripening stages were determined by reference degree (%) of the red zone on the surface of the fruit: white ripening stage (WR), 5-15%; red ripening stage (RR), 95-100%. Fruit weight, length, width, color, and firmness were examined as morphological characteristics; phenolics, organic acids, fatty acids, and sugars were evaluated as biochemical characteristics. Fruit weight was 22.63 g in the WR stage and 28.42 g in the RR stage. The dominant phenolic acid was p-hydroxybenzoic acid in both ripening stages (623 mg 100 …

Comparing Resource Use For Tomato Production On Urban, Peri-Urban And Rural Farms In Georgia, Usa, Nicole Kennard

Urban Food Systems Symposium

The large-scale urbanization of the global population has created convoluted and often inefficient food supply chains, where food is brought from rural areas across the world into cities. These food supply chains are vulnerable to shocks and stresses, as seen with the COVID-19 pandemic. These stresses are only expected to increase with the effects of climate change. Farmers are being pressured to grow more food for a growing global population whilst conserving natural resources. Thus, there has been increased effort to promote local agriculture to build food self-sufficiency in cities. However, the sustainability of different scales of local agriculture, such …

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U.S. By addressing …

Consumer Perceptions Of Organic, Natural, And Conventional Products When Provided At The Same Price., Kylee Sigmon

Agricultural Education, Communications and Technology Undergraduate Honors Theses

Today’s grocery stores are filled aisle to aisle with an overwhelming variety of options for the consumer. In a consumer-driven market structure, the food industry has grown to encompass many niche markets which meet the ever changing demands of consumers. From organically produced food to more modern agriculture practices and even to finding non-meat protein alternatives, the options are endless. However, in the United States (a country with a higher level of disposable income compared to others), the question arises are customers educated about what the products truly are that they are spending a price premium on?

Organic Dairy Profitability In Vermont: Measuring The Impacts Of Management And Market Forces On Farm Financial Performance, Jonathan Patrick Walsh

Graduate College Dissertations and Theses

The total number of operating dairy farms in the US has decreased by 74.1% over the past 25 years, dropping from 155,339 in 1992 to just 40,219 in 2017. As milk prices have fallen and become more volatile, profit margins have tightened, causing farmers to leave the business due to low profitability. Some Vermont farmers are currently looking for new economic strategies. One approach has been to transition from conventional to organic production in order to take advantage of better prices and new market opportunities. In order to make production decisions, farmers need accurate financial information on the costs and …

Fall crops are coming up, and they’re amazing. We started digging up the potatoes today and it is so crazy to see how many potatoes can grow from planting a chunk of potato with a couple of eyes on it! Some of these plants have two pounds of potatoes growing off of them. The pumpkins are already enormous, and the butternut squash are still ripening but are really good-sized already. The melons are taking longer than expected, but look great. Our one warm-season failure seems to be the eggplant- but watch them produce like crazy now that I’ve said that. …

Point-Of-Sale Specific Willingness To Pay For Quality-Differentiated Beef, Kar Ho Lim, Michael Vassalos, Michael R. Reed

Agricultural Economics Faculty Publications

Despite the growing interest of producers and consumers toward grass-fed, local, and organic beef, the supply chain for these products to reach consumers is not always clear-cut. Among the available options are direct-to-consumers and the conventional food supply chain. Although consumers may pay a premium for beef differentiated by quality attributes, the willingness to pay (WTP) difference across point-of-sales is unclear. In this study, we contrast the WTPs for conventional, grass-fed, local, and organic beef by brick-and-mortar supermarkets (B&Ms), farmers’ markets, and via online stores. We conduct a choice experiment with a nationwide online sample of American consumers. The findings …
