Cotton (Gossypium hirsutum L.) is as famous as “White Gold” due to its high quality fiber. Boron (B) is one of essential micronutrients involved directly or indirectly in many plant processes. Cotton growth, yield and quality are intensely influenced with B application. A 2 years field based study was conducted to explore the impact of foliar applied B (0.0, 0.5, 1.0, 1.5, 2.0, and 2.5 kg ha^-1) on productivity and quality of cotton cultivars (FH-113, MNH-786, and CIM-496). Outcomes of the experiment reflected that application of various levels of B significantly influences the growth and quality attributes …

The Soil Management Assessment Framework (SMAF) is a quantitative soil quality (SQ) evaluation tool that is widely applied to assess soil response to specific agricultural management practices over time. Considering the reported SQ benefits of agroforestry (AF) systems and the potential usefulness of SMAF, the objective of this study was to evaluate the effects of tree species (pecan [Carya illinoinensis (Wangenh.) K. Koch] and northern red oak [Quercus rubra L.]), soil fertility source (poultry litter [PL] and inorganic N fertilizer [control]), and soil depth (0–15 and 15–30 cm) on SMAF-derived SQ indices after 17 yr of management at an AF …

Identification And Management Of Scotch Thistle (Onopordum Acanthium L.) In Pastures, Rangelands, And Non-Crop Settings, Cody Zesiger, Jacob Hadfield, Kalen Taylor, Corey Ransom

All Current Publications

Scotch thistle (Onopordum acanthium) is an invasive species native to Eurasia. It was likely introduced into North America during the late 19th century (Young & Evans, 1969). Due to the plant’s size and prickles, a stand can damage pasture productivity, ruin campsites, or make trails nearly impassable. The thistle also outcompetes desirable plants and greatly reduces forage use by large animals. Since not all thistles are related or alike, it is essential to correctly identify Scotch thistle before making management decisions. This fact sheet provides information about identification, lifecycle and distribution, and management.

What Makes A Small Farm Successful? A Review Of Success Factors, Needs, And Challenges, Katie Tritsch, Ken Mix, Michelle L. Edwards, Manuel Piña Jr.

Journal of Extension

Small-scale farmers face unique challenges. In this review, we conceptualize small farm success by aggregating and categorizing results from recent (post-2000) literature on small farm success factors and producer needs assessments. Our findings suggest that small farm success is multifaceted and not limited to profitability. We find that small farms have a diverse range of needs, though little has been done to rank their importance. We conclude that future research would benefit from increased methodological transparency and a systematic approach to needs evaluation. We consider the role of Extension professionals regarding the continued success of small farms.

Digital Urban Agriculture As Disparate Development: The Future Of Food In Three U.S. Cities Through The Lens Of Stakeholder Perceptions, Networks, And Resource Flows, Michael Carolan

William & Mary Environmental Law and Policy Review

Urban agriculture takes many forms. Often, the term elicits images of raised beds, hoop houses, and, in those instances where topsoil is both present and non-contaminated, in-ground gardens—what I call traditional urban agriculture (“TUA”). But that imagery is changing, especially in some parts of the country where vacant space is scarce and land prices dear. In those instances, cities are seeing growth in digital urban agriculture (“DUA”). DUA, as defined here, refers to farming within urban and peri-urban areas that incorporates elements of automation, software, and/or silicon-based hardware into their operations. While this definition is not meant to draw a …

Cattle Producer Motivations And Willingness To Participate In Industry Animal Welfare Program Verification, Chase Decoite

Master's Theses

As consumers have become increasingly interested in where their food comes from and how it is grown, the cattle and beef industry is without exception. Many consumers are beginning to question traditional animal husbandry practices and on-farm animal welfare protocol. It is essential that the food system meets new demands and understands consumer views. In order to address these concerns, the industry has rallied around the Beef Quality Assurance (BQA) program to set the standard for cattle welfare and beef quality, with the explicit goal of improving consumer confidence. The goal of this research is to determine if cattle producers …

Understanding Producers’ Perspectives On Rotational Grazing Benefits Across Us Great Plains, Tong Wang, Hailong Jin, Urs Kreuter, Richard Teague

Economics Faculty Publications

Experimental findings on rotational grazing (RG) trials have generally differed from producer observations of RG outcomes on commercial scale ranches. Factors such as small plot size, short duration trials and relatively rigid grazing management that lacks responsiveness to the dynamic and complex social-ecological systems in grazing trials could all contribute to this disparity in outcomes. These differences call for a better understanding of producer perceptions of RG benefits. To fill this knowledge gap, we surveyed 4500 producers from the Northern and Southern Great Plains of the USA. Among the 875 respondents, 40.5% reported that they used continuous grazing (CG), 52.7% …

Research Note: Modified Serum Fluorescein Isothiocyanate Dextran (Fitc-D) Assay Procedure To Determine Intestinal Permeability In Poultry Fed Diets High In Natural Or Synthetic Pigments, Christine N. Vuong, Garrett J. Mullenix, Michael T. Kidd, Walter G. Bottje, Billy M. Hargis, Guillermo Tellez-Isaias

Poultry Science Faculty Publications and Presentations

Oral administration of fluorescein isothiocyanate dextran (FITC-d) has been used as an indicator for intestinal permeability in poultry research for several years. Under healthy conditions, tight junctions in the intestinal wall will not allow the 4-6kDa FITC-d to enter the bloodstream. Detection of FITC-d in serum (1-hour post-oral administration of FITC-d) has proven to be a reliable indicator of leaky gut syndrome (increased intestinal inflammation and disruption of tight junctions). Administration of supplementary phytobiotics in feed, particularly products with high beta-carotene levels or other pigments, has resulted in strong serum background fluorescence, which can render this assay unreliable. …

Poultry Science Faculty Publications and Presentations

Water scarcity is a global reality and with the anticipated population growth, freshwater resources will be further strained to meet both human and agriculture applications. To ensure a water sustainable and food secure future, all aspects of agriculture must become more efficient. Two strategies were explored. The first strategy was to develop a more efficient and accurate method for measuring water consumption/inputs in agriculture. To date, water measuring technology has lacked the necessary sophistication to assure accuracy and repeatability of low flow water usage. The second strategy utilized the improved water measuring technology, to develop water-efficient genetics in agricultural populations …

Real-Life Conundrums In The Struggle For Institutional Transformation, Julia Mcquillan, Nestor Hernandez

Department of Sociology: Faculty Publications

Intersecting systems of inequality (i.e., gender and race/ethnicity) are remarkably resistant to change. Many universities, however, seek National Science Foundation Institutional Transformation awards to change processes, procedures, and cultures to make science, technology, engineering, and mathematics (STEM) departments more inclusive. In this article we describe a case study with observations for eight years of before (2000–2007), five during (2008–2013), and seven after (2014–2020) intensive efforts to increase women through reducing barriers and increasing access to women. Finally, we reflect on flawed assumptions built into the proposal, the slow and uneven change in the proportion of women over time, the strengths …

Can Date Palms Planted For Urban Landscaping Purposes Serve In The Production Of Edible Fruits? An Evaluation Of Tissue Element Concentrations, Fruits Quality And Health Risks, Khattab Omar Adam Al Nidawi

Theses

More than 80.000 date palms are grown for ornamental purposes as part of public urban greenery in the city of Al Ain. The fruits that these palms produce, are often not valorized as food for humans, due to the fear that they might contain potentially hazardous pollutants, such as heavy metals. When palms are grown near roads or in urban environments, pollution might arise from the exhaust and dust produced by vehicles, industrial activities, as well as through urban waste material deposition, including irrigation with treated sewage effluent. On the other hand, many date palms grown for landscaping purposes might …
