Understanding Current Labor Shortage And Mechanization In New Jersey Nursery Crop Operations, Hemant Gohil, Timothy Waller, Raul Cabrera

The Journal of Extension

We conducted a survey of New Jersey’s nursery industry to understand the current levels of labor shortage, how this has affected specific tasks related to the production capacity of the industry, and the actual level of mechanization. Survey results identified priority areas needing mechanization. There is a need for greater mechanization in almost all areas of nursery production to reduce the reliance on labor and or improve the efficiency of labor. Other Implications related to Extension programming on nursery mechanization are also discussed.

Colored Sweet Bell And Tapered Pepper Cultivar Evaluation For High Tunnel Production In West-Central Indiana, 2022, Petrus Langenhoven, Lian Mahorith Duron Alvarado, Eduardo Jose Miranda Oviedo

Midwest Vegetable Trial Reports

Colored sweet bell-shaped and tapered peppers are a staple at the farmers' market. Many small and medium-sized farming operations in Indiana grow this summer crop. High tunnels allow growers to protect their crops and extend their growing season. Sweet peppers, in particular, benefit from the unique growing environment created by the high tunnel. Planting of peppers can start at least 2-4 weeks earlier in the spring, and production can continue into the fall until the first hard freeze. Pepper variety performance data for Indiana is not readily available. We are working hard to change that. Currently, we have evaluated twenty-five …

Oxidation is one of the most critical processes in food systems. It has an impact on a variety of dietary ingredient interactions, resulting in both desired and unwanted results. It was found in many studies that high concentrations of synthetic antioxidants may havesome carcinogenic effects in some animals, thus natural antioxidants would be analternative to synthetic antioxidants in food. These natural antioxidants can be present in any plant part, including grains, fruits, leaves, nuts, seeds, roots and barks. Many studies showed that there is an inverse relationship between the dietary intake of medicinal plants rich in antioxidants and the prevalence …

United We Stand? Investigating The Impact Of Unified Dues Agreements Between State And National Career & Technical Education (Cte) Professional Organizations On Cte Funding In The Southern States, Justin Ryan Hall

Theses and Dissertations

Career and Technical Education (CTE) teachers have long been active in lobbying the federal and state governments in support of CTE through their professional organizations, but these are not traditionally considered interest groups. This study sought to determine if the formal relationships—dues agreements—between the two largest national professional organizations, and their state affiliates had an impact on state funding for CTE. The impacts of professional organization unity, membership rates, and lobbying expenses on state-level CTE funding were analyzed through the lens of interest group theory, a subfield of political science. Within this population (N = 13), 1) a link …


The Effects Of Glyphosate Salts And Volatility-Reducing Agents (Vra) On Dicamba Volatility, Nicole Glenn 2022 Mississippi State University

The Effects Of Glyphosate Salts And Volatility-Reducing Agents (Vra) On Dicamba Volatility, Nicole Glenn

Theses and Dissertations

Dicamba is often tank mixed with glyphosate to increase herbicidal efficacy but may contribute to off-target movement (OTM). In recent years, volatilization has become problematic for dicamba-containing herbicides, resulting in increased regulatory requirements necessitating the use of volatility-reducing agents (VRA) for application. Research was conducted in 2021 and 2022 using low tunnels in a field environment and humidomes in a greenhouse environment to further assess how glyphosate salts and VRAs affect dicamba volatility. Our data indicate that the inclusion of glyphosate to dicamba can increase dicamba volatility, depending on the glyphosate salt used. The inclusion of the evaluated VRAs will …


Biological Remediation Of Fragipan, Corey Hale 2022 Murray State University

Biological Remediation Of Fragipan, Corey Hale

Honors College Theses

The fragipan layer in the soil is a naturally occurring subsurface layer that restricts water percolation as well as inhibits root growth. A fragipan layer can be found almost ubiquitously across Southwestern Kentucky. This limits how agriculturalists manage soils in this area. It has been recently discovered by the University of Kentucky that Annual Ryegrass roots produce 3,4 dihydroxyphenylpropionic acid (DHPPA) that reacts with this hardpan to weaken the layer. Certain bacteria, such as Escherichia coli, Lactobacilli, and Bifidobacteria can also synthesize DHPPA through a breakdown process of chlorogenic acid. This reaction typically happens in the human digestive tract. …


Adapting Network Theory For Spatial Network Externalities In Agriculture: A Case Study On Hemp Cross-Pollination, Jeffrey S. Young, Tanner J. McCarty 2022 Murray State University

Adapting Network Theory For Spatial Network Externalities In Agriculture: A Case Study On Hemp Cross-Pollination, Jeffrey S. Young, Tanner J. Mccarty

Faculty & Staff Research and Creative Activity

Growers have increasingly expressed frustration over the negative externalities created by their neighbor's production practices. These spatial agricultural network problems include issues such as cross-pollination and herbicide drift. We develop novel methods for estimating parameters that allow us to adapt and apply general network diffusion models to these spatial agricultural network problems. Doing so allows us to calculate externality damage within a region and calculate cost-effective policies for alleviating that externality. We empirically illustrate, motivate, and test this approach by applying it to hemp. We find that network structure is an important factor in externality size and cost-effective policy response …

Deciphering The Genetic Architecture Of Key Female Floral Traits For Hybrid Wheat Seed Production, Juan Jimenez 2022 University of Nebraska-Lincoln

Deciphering The Genetic Architecture Of Key Female Floral Traits For Hybrid Wheat Seed Production, Juan Jimenez

Theses, Dissertations, and Student Research in Agronomy and Horticulture

Wheat (Triticum aestivum L.) is a staple cereal that provides 20% of the calories and proteins in human intake (Ray et al., 2013). Global population is projected to increase to 9.7 billion by 2050. Food production must increase by 70% to feed this future population. Wheat production is in crisis due to political and environmental challenges and is projected to decline by 0.8% in 2022 (FAO, 2022). To ensure food security yield genetic gain must increase by around 1.4% annually. Taking advantage of heterosis, hybrid wheat has the potential to boost grain yield. However, hybrid wheat seed production systems …
