Micronutrient Concentration Effects On Lettuce Growth And Susceptibility To Pythium, Kalyn M. Helms

Graduate Theses and Dissertations

In hydroponic production waterborne pathogens such as Pythium are ubiquitous and continually threaten a wide range of Controlled Environment Agriculture (CEA) crops in hydroponic production, including but not limited to: lettuce, spinach, basil, arugula, cucumber, tomato, sweet pepper, roses, chrysanthemums, and cannabis (Sutton et al., 2006; Gull, 2002; McGehee and Raudales, 2021; Gillespie, 2020). Despite extensive sanitation measures, disease control in hydroponics is fallible and requires constant surveillance and management to minimize outbreaks (Sutton et al., 2006). A potential disease suppression strategy is to increase micronutrient concentrations within hydroponic systems to naturally strengthen plant defenses against pathogens such as Pythium. …

Evaluating Flavor And Aroma Attributes Of Arkansas-Grown Horticultural Crops, Jordan Chenier

Graduate Theses and Dissertations

Arkansas has a climate and geography that allows for the production of unique horticultural crops, including hops (Humulus lupulus L.), blackberries (Rubus subgenus Rubus), and muscadine grapes (Vitis rotundifolia). These crops not only have potential for growers in Arkansas but have unique flavor and aroma attributes that impact marketability. Volatile compounds present in many different agricultural plants are the primary source of biologically-derived aromas and flavors. Therefore, the volatile and other quality attributes of hops, blackberries, and muscadine grapes were evaluated at the University of Arkansas (UA System) Division of Agriculture. The quality, volatile, and sensory attributes of four hops …

Environmental Weed Risk Assessment Protocol For Growing Non-Indigenous Plants In The Western Australian Rangelands, Geoff A. Moore Mr, Christine Munday Ms, Papori Barua Dr

Bulletins 4000 -

This bulletin is a post-border environmental weed risk assessment (WRA) protocol which is based on the Environmental WRA Protocol developed for the Future Farm Industries Co-operative Research Centre (FFI CRC), but with some changes to reflect the different environment and objectives.

The WRA protocol was developed specifically as a post-border assessment of non-indigenous species that may have agricultural value in the WA rangelands and the risk that they may become environmental weeds. Weeds can occur in many land-use systems including agriculture, horticulture and forestry; however, the focus of this protocol is on the risk that non-indigenous agricultural plants may become …

Helping Utah Landowners Reduce Pesticide Use Through A Statewide Ipm Program, Nick Volesky, Mair Murray

Outcomes and Impact Quarterly

The Utah Integrated Pest Management (IPM) program provides outreach and education to Utahns to reduce pesticide use and ultimately protect human and environmental health. In 2022, the IPM program responded to stakeholders’ needs by partnering with county Extension offices to deliver eight (8) in-person workshops across the state. The workshops connected Extension specialists and county faculty with managers of home landscapes and farms. The objective of the workshops was to provide participants with IPM skills to identify, monitor, and manage pest problems in preparation for the upcoming growing season.

High Tunnel Construction Cost Calculation Workbook, Shannon Rauter, Melanie Stock, Brent Black, Dan Drost

All Current Publications

The cost of building a high tunnel fluctuates over time with supply prices. This Excel workbook accompanies the USU Extension fact sheet, "Constructing a Low-cost High Tunnel" by Black, Drost, Rowley, and Heflebower (2011) and allows users to input local supply costs. The workbook then calculates the cost to build a USU low-cost high tunnel with several design options according to high tunnel length and door structure. It also provides an example calculation based on April 2022 pricing for reference.

Influence Of Fertilizer Rate On Swollen Stem Formation (“Bulbing”) And Vitamin C Content In Different Kohlrabi Cultivars, Mark Iradukunda, Paul E. Read

Honors Theses

Kohlrabi (Brassica oleracea Gongylodes Group) is a vegetable crop found in the Brassicaceae, and it is rich in antioxidants such as vitamin C. Vitamin C helps in oxidative damage repair and strengthens the immune system, so exploring vitamin C sources may contribute to improving human health. The objective of this study was to determine the effect of different fertilizer rates on kohlrabi yield, in terms of the swollen stem and the vitamin C content, and if those effects are similar in different kohlrabi cultivars. In this greenhouse study, we fertilized four potted kohlrabi cultivars with a common water-soluble greenhouse fertilizer …
