Origin, Rise And Development Of American Upland Cotton And Their Status At Present. Second Edition, Ed. By F.M. Bourland, J. O. Ware

AAES Research Reports and Research Bulletins

American Upland cotton (Gossypium hirsutum) is a Dixie product. Although the stocks of the species were brought from elsewhere, new types (through series of adaptational changes) formed this distinctive group—the final characteristics of which are a product of the Cotton Belt of the United States. These biological processes were considerably aided by man and the steps of development possibly were about as follows: (a) natural selection took place in the earlier introductions, (b) seed were saved from the more choice stocks, (c) series of subsequent introductions were obtained from the better sources, (d) these were acclimatized and the superior ones …

This study builds upon previous consumer perceptions of GMOs studies. A need existed to determine what, if any, effects social media messages about GMOs had on consumer perceptions in Arkansas. The study utilized a qualitative approach with three focus groups. Data were analyzed using descriptive code. Participants were found to have a general understanding of GMOs, though discussion about what a GMO product was took an uncertain tone. Most participants did not consider GMOs as a factor when purchasing products. Rather participants considered characteristics such as price, quality, and convenience. Participants did not believe the infographics had changed their opinions …

Growing Agriculture Literacy’S Presence In America’S Classrooms, Emily Stone

Journal of Food Law & Policy

“Americans, as a whole, were at least two generations removed from the farm and did not understand even the most rudimentary of processes, challenges, and risks that farmers and the agricultural industry worked with and met head-on every day.” This quote perfectly describes the mindset of agriculture stakeholders in 1981 as they began to realize the drastic steps our education system had taken away from using principles of agriculture in K-12 education. As they saw it, Americans were moving out of rural America, away from farms, and becoming less connected to the food they daily consumed. Simultaneously, the education system …

Utilizing The Genetic Potentials Of Traditional Rice Varieties And Conserving Rice Biodiversity With System Of Rice Intensification Management, Yheni Dwiningsih

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

The genetic potentials of rice cultivars will need to be expressed to their fullest if global rice production is to be expanded enough by 2050 to meet the increased demand of the expanding population while the availability of land and water per capita dwindles. New and ‘improved’ rice varieties have contributed greatly to increased production over the past 50 years, but the rate of rice yield increase based on genetic changes has declined in recent decades compared with the early years of the Green Revolution. In fact, many rice consumers continue to prefer to consume ‘traditional’ rice varieties (referred to …

Adoption And Continued Use Of Irrigation Management Practices In Arkansas, Evelyn Osei

Graduate Theses and Dissertations

The paper assesses row crop producers continued use of irrigation management practices, namely the decision to continue rather than stop the use of irrigation practices, using a probit with a sample selection model. To better explain and increase user acceptance, we must understand why producers adopt and continue using irrigation management practices. Past studies have researched the adoption of management practices. However, it is also essential to consider what factors influence continued use and why producers discontinue irrigation practices after adoption. This is the first study to investigate factors influencing the continued use of irrigation management practices in Arkansas. Producers …

Economic Analysis Of Sod-Seeded Summer Annuals For Forage And Grazing, Ivanelle Meyer

Graduate Theses and Dissertations

Forage and pasture trials were conducted over the summers of 2021 and 2022 to assess how forage production and nutritive value of sorghum sudangrass, cowpea, and sorghum sudangrass-cowpea mixtures, sod-seeded to bermudagrass pasture would impact stocker cattle performance. The forage trials compared forage production and quality when poultry litter was surface or sub-surface applied biennially in comparison to a no poultry litter control. Poultry litter is a nutrient dense fertilizer utilized on pastures in the mid-southern United States to increase forage nutritive value and yield. Broadcasting poultry litter results in more nutrient losses due to runoff and nitrogen volatilization compared …

Economic Analysis Of Solar Investment In An Agricultural Setting, Morgan King

Graduate Theses and Dissertations

Robust financial modelling is critical for evaluating solar investments in agricultural applications. Agricultural producers with electricity-intensive systems (especially poultry houses but also, for example, irrigation pumps) face monthly electricity bills in the thousands of dollars. Further, volatile electricity bills, because of uncertain electric rate inflation, add to financial risk as utility costs make up a large portion of operating costs. While solar panels reduce input cost risk with certain installation cost up front, producers are hesitant to invest given long payback periods, uncertainty about the future of net metering, and high financial leverage. To enable producers to accurately assess the …

The Alternative Livestock Revolution: Prospects For Consumer Acceptance Of Plant-Based And Cultured Meat In South Africa, Chiedza Tsvakirai, Lawton Nalley, Shelby Rider, Ellen Van Loo, Makgopa Tshehla

Agricultural Economics and Agribusiness Faculty Publications and Presentations

Although South Africa accounts for half of the alternative meat market for the African continent, there remains a lack of information about consumer demand for plant-based and lab-cultured meat and its market potential domestically. This study reports the results of a nationwide survey of 649 South African consumers who completed a choice experiment in which they selected among conventional beef and three alternative burger patties at varying prices. Results indicate that holding prices constant and conditional on choosing a food product, 21% of the market share was estimated for plant-based meat alternatives and 38% for lab-cultured meat.

Using Post-Season Tissue Nitrogen Concentrations To Predict Adequacy Of In-Season Nitrogen Management, Kyle Hoegenauer, Trenton Roberts, Carrie Ortel, Jarrod Hardke, Mike Richardson, Mike Daniels

Crop, Soil and Environmental Sciences Faculty Publications and Presentations

High-yielding mechanized rice production requires large amounts of nitrogen (N) fertilizer, which can be particularly costly to producers when applied in excess. The development of a tissue test to detect overapplication of N to rice is needed. Nitrogen response trials arranged in a randomized complete block design were established to identify a critical concentration threshold for a tissue test to detect excess N availability. Rice stalk samples were collected from 0 to 20 cm above the soil within 5 days of harvest and analyzed for NO₃ −-N concentration. Two models were fit to the data to represent rice grain …

Understanding Functional Benefits Of Isoleucine And Arginine On Poultry Performance And Health., Roshan Adhikari, Jason T. Lee, Keith Haydon

Proceedings of the Arkansas Nutrition Conference

Poultry industry is rapidly moving towards utilizing the best ingredients to precisely feed the birds for better performance, welfare, health, and profitability. One of the practices that evolved over time with research is better optimization of amino acid utilization in the diets thus changing the crude protein landscape. Historically, if we compare the modern diets to diets from 1980, significant changes are visible in the use of unbound or crystalline amino acids leading to reduced levels of CP and reduced unutilized nitrogen in the diets. Multiple feed-grade amino acids are available in a cost-effective manner in poultry diets. Multiple research …

Agricultural Economics and Agribusiness Faculty Publications and Presentations

onservation agriculture, a sustainable farming practice combining no or minimum soil disturbance, crop diversification, and soil cover, can benefit humans and the biophysical environment. However, less than half of Sub-Saharan African countries implement conservation agriculture, and the majority of smallholder farmers are using unsustainable practices. Research and field trials on conservation agriculture adaptation to soil and agroecological conditions are vital for increasing adoption of conservation agriculture in Sub-Saharan Africa. The objectives of this study were to (i) evaluate the change in soil chemical properties and soil biology from implementation of conservation agriculture, (ii) assess cowpea (Vigna unguiculata L. Walp.) …

Feed Formulation: Expanding Our Horizons Beyond The Simple Provision Of Least-Cost Diets, Rick Kleyn, Mariana Ciacciariello

Proceedings of the Arkansas Nutrition Conference

Commercial feed formulation is typically based on linear programming (LP) algorithms that derive a least-cost solution for a blend of ingredients that meet specific nutrient criteria. This methodology has been effectively used for decades, but how we achieve our primary goal, which is sustainable poultry production, needs to be reconsidered in broader terms. Some of the issues that this paper will deal with are: not all parameters that we consider are linear and additive; we are still unsure of how to build the matrix required for feed formulation; dealing with the variability encountered in every batch of ingredient remains a …

No Antibiotic Ever (Nae) Versus Conventional Broiler Production: It’S Complicated, Marcos H. Rostagno

Proceedings of the Arkansas Nutrition Conference

Broiler production has evolved significantly over the years to meet a constant growing demand for animal protein. Rooted on major advances in genetics, facilities and environmental conditions, management, and specially, in nutrition and health, the U.S. broiler industry improved tremendously in productivity and efficiency, clearly demonstrated by a marked reduction of the average market age (i.e., days to market), while significantly increasing average market weight, breast meat yield and feed efficiency (National Chicken Council, 2023). For decades, conventional broiler production was dominant, with extensive use of antibiotics to promote growth and manage disease challenges (prevention and control). However, concerns over …

Organic Trace Minerals In Environmentally Sustainable Systems, Sergio L. Vieira, Julmar C. Feijó, André Favero

Proceedings of the Arkansas Nutrition Conference

Essential trace minerals (Zn, Cu, Fe, Mn, Se and I) are traditionally included as supplements through mineral premixes in poultry feeds. In comparison to other essential nutrients, as well as energy, they are scarcely studied. The essentiality of a nutrient, by definition, refers to the nutrient role in normal body function, such as growth or egg production, and considers that they cannot be synthesized by the body and, therefore, must be supplied from the feed.

Application Of New Molecular Tools To Assess Virus Viability In Production Animals, Declan C. Schroeder

Proceedings of the Arkansas Nutrition Conference

Persistent viral infections routinely impose an inconvenient, always costly but thankfully not all too often catastrophic outcome on our modern food system. Managing viruses is key for all concerned if our objective is to meet the ever-growing demand to high-value animal protein. Whether it’s the impact influenza A virus (IAV) has on the avian or swine industries, Porcine reproductive and respiratory virus (PRRSV) on the swine or Deformed wing virus (DWV) on honey bees in both the honey and pollinator sectors - the negative impact and damaging cost to the individual producer, country and global economy cannot be overstated.

Proceedings of the Arkansas Nutrition Conference

The primary goal of the presentation is to share a long-term overview of how broiler production has changed over the last 35 years in areas of bird performance, production costs, particularly in the area of feed ingredient cost per lb. and illustrating how poultry nutritionists have adapted feed formulations to meet the changes in performance and cost.

Agricultural Pesticide Regulatory Environment For Pollinator Protection Across Geographical Regions, Ngoc T. Phan, Edwin G. Rajotte, Guy Smagghe, Zong-Xin Ren, David J. Biddinger, Neelendra K. Joshi

Entomology and Plant Pathology Faculty Publications and Presentations

The alarming decline of pollinator populations has raised significant concerns worldwide and prompted the need for effective pesticide risk assessment within the Integrated Pest and Pollinator Management (IPPM) framework. This paper examines the diverse approaches to pollinator protection within the pesticide regulatory environments of the United States (US), the European Union (EU), and selected Asian countries. The US adopts a reactive approach, regulating pesticides only after evidence of harm emerges, while the EU embraces a proactive stance under the precautionary principle. The EU has implemented stringent regulations, including neonicotinoid bans, and conducts coordinated research on pesticide impacts. In contrast, some …

Summaries Of Arkansas Cotton Research 2022, Fred Bourland

Arkansas Agricultural Experiment Station Research Series

The current economic environment continues to drive the need to produce record or near-record yields to be profitable. Price volatility in 2022 added another level of difficulty in the quest for being profitable. The cotton market saw significant movement after reaching a $1.5802 per pound high in May 2022, cotton prices corrected and more than halved in value at the October 2022 low, and then consolidated around the 80 cents per pound level in December 2022 (Cotton is Consolidating). Great uncertainties still exist for the upcoming season, most of which are outside of our control. These include, but are not …
