Urban Horticulture, From Local Initiatives To Global Success Stories, Roland Ebel, Esmaeil Fallahi, John L. Griffis Jr., Dilip Nandwani, Donielle Nolan, Ross H. Penhallegon, Mary Rogers

Agricultural and Environmental Sciences Faculty Research

Urban horticulture describes economically viable horticultural production activities conducted in a city or suburb. It is a growing segment of horticulture in the United States as well as in developing countries, where the enormous growth of megalopolis is not backed by a simultaneous increase of farmland or agricultural productivity. Today, urban horticulture includes food sovereignty in underprivileged neighborhoods, increased availability of vegetables and fruits in big cities, healthy and diverse diets, improved food safety, low transportation costs, efficient resource use, and the mitigation of environmental impacts of horticultural production such as the emission of greenhouse gases. The workshop “Urban horticulture: …

Compositional Characterization Of Different Industrial White And Red Grape Pomaces In Virginia And The Potential Valorization Of The Major Components, Qing Jin, Joshua O'Hair, Amanda C. Stewart, Sean F. O'Keefe, Andrew P. Neilson, Young-Teck Kim, Megan Mcguire, Andrew Lee, Geoffrey Wilder, Haibo Huang

Biology Faculty Research

To better evaluate potential uses for grape pomace (GP) waste, a comprehensive chemical composition analysis of GP in Virginia was conducted. Eight commercial white and red pomace samples (cv. Viognier, Vidal Blanc, Niagara, Petit Manseng, Petit Verdot, Merlot, Cabernet Franc, and Chambourcin) obtained from different wineries in Virginia, USA were used. For extractives, GPs contained 2.89%–4.66% titratable acids, 4.32%–6.60% ash, 4.62%–12.5% lipids with linoleic acid being the predominant (59.0%–70.9%) fatty acid, 10.4–64.8 g total phenolic content (gallic acid equivalents)/kg GP, 2.09–53.3 g glucose/kg GP, 3.79–52.9 g fructose/kg GP, and trace sucrose. As for non-extractives, GPs contained 25.2%–44.5% lignin, 8.04%–12.7% glucan, …

Diversification Through ‘Fun In The Farm’: Analyzing Structural Factors Affecting Agritourism In Tennessee, Aditya R. Khanal, Ummey Honey, Omobolaji Omobitan

Agricultural and Environmental Sciences Faculty Research

With recent development, agritourism – visiting a working agricultural setting such as farm and ranch for leisure, recreation, or educational purposes – is gaining popularity in the US. Agritourism can be considered as a viable alternative agricultural enterprise to enhance income and sustainability of farms. This study maps agritourism locations and analyzes the structural factors affecting agritourism location and establishments. Using zip-code level location information, county-level data from Tennessee and spatial regression models, we found significant effects of rural factors, demographics, and educational-, economic-, and cultural- capital factors and their interactions on the location and establishment of agritourism farms. The …

Detection Of Salmonella Typhimurium In Romaine Lettuce Using A Surface Plasmon Resonance Biosensor, Devendra Bhandari, Fur-Chi Chen, Roger C. Bridgman

Human Sciences Faculty Research

Leafy vegetables have been associated with high-profile outbreaks causing severe illnesses. Timely and accurate identification of potential contamination is essential to ensure food safety. A surface plasmon resonance (SPR) assay has been developed for the detection of Salmonella Typhimurium in leafy vegetables. The assay utilizes a pair of well characterized monoclonal antibodies specific to the flagellin of S. Typhimurium. Samples of romaine lettuce contaminated with S. Typhimurium at different levels (between 0.9 and 5.9 log cfu/g) were pre-enriched in buffered peptone water. Three SPR assay formats, direct assay, sequential two-step sandwich assay, and pre-incubation one-step sandwich assay were evaluated. All …

Responses Of Soil Carbon Sequestration To Climate-Smart Agriculture Practices: A Meta-Analysis, Xiongxiong Bai, Yawen Huang, Wei Ren, Mark Coyne, Pierre-Andre Jacinthe, Bo Tao, Dafeng Hui, Jian Yang, Chris Matocha

Biology Faculty Research

Climate-smart agriculture (CSA) management practices (e.g., conservation tillage, cover crops, and biochar applications) have been widely adopted to enhance soil organic carbon (SOC) sequestration and to reduce greenhouse gas emissions while ensuring crop productivity. However, current measurements regarding the influences of CSA management practices on SOC sequestration diverge widely, making it difficult to derive conclusions about individual and combined CSA management effects and bringing large uncertainties in quantifying the potential of the agricultural sector to mitigate climate change. We conducted a meta-analysis of 3,049 paired measurements from 417 peer-reviewed articles to examine the effects of three common CSA management practices …

Model Simulation Of Cucumber Yield And Microclimate Analysis In A Semi-Closed Greenhouse In China, Xiaotao Ding, Yuping Jiang, Dafeng Hui, Lizhong He, Danfeng Huang, Jizhu Yu, Qiang Zhou

Biology Faculty Research

Adequate greenhouse environmental management is very important for improving resource use efficiency and increasing vegetable yield. The objective of this study was to explore suitable climate and cultivation management for cucumber to achieve high yield and build optimal yield models in semi-closed greenhouses. A fruit cucumber cultivar Deltastar was grown over 4 years in greenhouse and weekly data of yields (mean, highest and lowest) and environmental variables, including total radiation, air temperature, relative humidity, and carbon dioxide (CO2) concentration were collected. Regression analyses were applied to develop the relationships and build best regression models of yields with environmental variables using …

Trap Tree And Interception Trap Techniques For Management Of Ambrosia Beetles (Coleoptera: Curculionidae: Scolytinae) In Nursery Production Get Access Arrow, Karla M. Addesso, Jason B. Oliver, Nadeer N. Youssef, Paul A. O'Neal, Christopher Ranger, Michael E. Reding, Peter B. Schultz, Christopher T. Werle

Agricultural and Environmental Sciences Faculty Research

The majority of wood-boring ambrosia beetles are strongly attracted to ethanol, a behavior which could be exploited for management within ornamental nurseries. A series of experiments was conducted to determine if ethanol-based interception techniques could reduce ambrosia beetle pest pressure. In two experiments, trap trees injected with a high dose of ethanol were positioned either adjacent or 10–15 m from trees injected with a low dose of ethanol (simulating a mildly stressed tree) to determine if the high-dose trap trees could draw beetle attacks away from immediately adjacent stressed nursery trees. The high-ethanol-dose trees sustained considerably higher attacks than the …

Poultry And Egg Education Project (Peep) Curriculum Resource, Sandria L. Godwin, John Ricketts

Extension Publications

The PEEP Curriculum for youth is one of the major outcomes associated with a USDA-AFRI project to develop a research-based educational program comprised of consumer-focused, impactful messages addressing poultry and egg safety practices. The six peer-reviewed lesson plans and objectives herein were developed directly from the research associated with this project.

The lesson plans are complete with requisite background information, objectives, activities, videos, and evaluation tools. The lessons can be integrated into standing or special 4-H programs related to poultry, STEM, and health and food science. The lessons can also be integrated into school-based agricultural education programs, specifically in pathways …
