Impacts Of Cover Crop, Soil Steaming, And Plastic Mulch On Field-Grown Tomato Production And Virus-Induced Gene Silencing In Antirrhinum, Penstemon, Petunia, Rosa, And Rudbeckia, Brenton Andrew Earl Breland

Theses and Dissertations

Weeds and soil-borne diseases can cause large yield losses in field-grown tomato (Solanum lycopersicum) production. Techniques have been developed to reduce soil-based problems. In this study, we evaluated the impacts of cover crops, soil steaming, and plastic mulch to reduce weed and disease pressure in field-grown tomatoes. Four cover crop treatments were grown in the fall and winter before spring planting. Soils were steamed to a target temperature of 71.1 °C for 0, 5, or 20 minutes. Plastic mulch was also used on half of the rows. Yield, weed densities, and disease incidence were recorded.

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. …

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

Effect Of Harvest Time On The Incidence Of Red Drupelet Reversion And Development Of Tetraploid Linkage Maps In Blackberry, Mitchell E. Armour

Graduate Theses and Dissertations

The cultivated eastern U.S. blackberry (Rubus L. subgenus Rubus Watson) has gone through tremendous strides in both trait improvement and market outreach at the University of Arkansas System Division of Agriculture (UA System). What began as primarily a pick-your-own local fruit found mostly in the wild, has become a commercialized year-round product in most major U.S. grocery retailers. This could not have been achieved without decades of diligent breeding efforts. Although the genetic improvement of fresh-market blackberries has advanced, there are still issues that need to be addressed. One issue is the prevalence of red drupelet reversion (RDR), a physiological …

Efficacy Of Antimicrobial Mitigation On Escherichia Coli Cfu And Growth And Development Of Hydroponic Leafy Greens, Nathan J. Eylands

Graduate Theses and Dissertations

The Food and Drug Administration (FDA) have set new standards that apply to agriculturalists producing crops eaten fresh and/or raw by consumers. This new produce safety rule, known as the Food Safety Modernization Act (FSMA), has established science-based standards for all areas of production in agriculture with regards to microbial contamination. Escherichia coli (E. coli) O157:H7 is a particular bacterium of concern under FSMA guidelines. Grower compliance is mandatory and therefore vital to the continuation of any farm. Greenhouse hydroponic growers have shown advantages in efficiency when compared to conventional farming methodology. Those, however, with recirculating hydroponic systems face unique …

Horticulture For Pollinator Conservation, Carter M. Westerhold

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

Pollinators worldwide are declining. Consequently, the agricultural and ecological services these insects provide are in danger of being lost. Land use intensification, via urbanization, has greatly influenced this decline in pollinators. Luckily, through targeted horticultural practices, stable populations of pollinators can be sustained within urban areas. The horticultural practices of planting diverse floral resources and managing pollinator habitat in urban areas can sustain these populations. Two studies were conducted with the intent to identify horticultural knowledge gaps that could be reduced to aid in pollinator conservation efforts. First, a study to compare Nebraska native and non-native ornamental plants was conducted. …

Optimization Of Overhead Irrigation In Relation To Irrigation Water Use Efficiency In The Louisiana Nursery Industry, Mark A. Wilson

LSU Master's Theses

Irrigation efficiency is an essential component of nursery production in the United States. To increase productivity of Louisiana growers, a series of studies were conducted to evaluate current nursery water practices. The objectives were to determine current irrigation practices; evaluate actual water usage; and compare nursery media for water utilization. A mailed survey determined that the majority of growers used can yard production (63%), overhead irrigation (79%), had no irrigation manager (82%) and did not collect/reuse water(61%); 50% do not test/calibrate their irrigation system. Based on this information, five nurseries using overhead irrigation were selected to determine water application and …

Improving Wildflower Longevity In Roadside Seeding Areas, Walter Schacht, Jonathan M. Soper, Carol Wienhold

Nebraska Department of Transportation: Research Reports

Re-vegetation efforts on bare roadsides of newly-constructed highways are primarily focused on the stabilization of soil to reduce rates of erosion. The Nebraska Department of Transportation (NDOT) seeds roadsides with a diverse mixture of grasses and wildflowers for site stabilization as well as to enhance the visual quality of roadsides. Although grasses dominate roadside plantings in terms of cover and density, wildflowers are largely responsible for the visual enhancement of recently-seeded roadsides. In addition to the visual component, wildflowers provide essential ecological functions on roadsides. Wildflowers improve water and nutrient cycling in the compacted roadside soils by increasing water infiltration …

In Conclusion, Something To Chew On: Native Plant Foods Of The Gold Coast, Simon Grigalius, Daryl Mcphee

Daryl McPhee

Extract: Ask most people what Gold Coast food is and you may hear answers like the ubiquitous prawn cocktail with avocado, a burger with ' fresh' pineapple available at the local surf club, or fish and chips (eaten on the beach to give it the seaside connection), with the fish often imported from New Zealand or Vietnam. None of this is the true food of the Gold Coast.
