The Sletr1-2 allele, which reduces ethylene sensitivity in tomatoes, offers a promising approach to extending fruit shelf life by slowing ripening-related metabolism. However, the trait’s success depends on compatibility with the recipient cultivar’s genetic background. This study evaluated fruit characteristics of F1 near-isogenic line (NIL) hybrids carrying Sletr1-2 in the commercial backgrounds ‘Costoluto’, ‘Oxheart’, and ‘Sart Roloise’. The field trial was carried out between May and August 2024 at the Experimental Station of Universitas Padjadjaran, Sumedang, Indonesia, following a randomized complete block design with eight biological replicates for each treatment. The results revealed that fruit characteristics of F1 NIL Sletr1-2 …

Investigating Nutrient Management & The Impacts Of Nitrogen On Blackberries Across Arkansas And The Southeast, Amanda Michelle Lay-Walters
Graduate Theses and Dissertations
Current blackberry (Rubus subgenus Rubus) research on nutrient needs, monitoring practices, and dynamics in the United States has primarily been conducted on cultivars popularly grown in the Pacific Northwest. Thus, regional research is required to understand the needs of blackberry cultivars grown in the southeastern U.S., with southeastern U.S. production practices. In 2022 and 2023, 12 cultivars of blackberry, across seven states, were leaf tissue sampled across multiple phenological stages for nutrient analysis. In Clarksville, AR from 2022 to 2024, six rates of N were applied to established ‘Ouachita’ blackberry plants. During the trial, plant yield, post-harvest fruit quality, fruit …

Patch Mow Grazing: Investigating The Effects Of Mowing On Forage Nutritive Value, The Biomass–Nutritive Value Relationship, And Herbivore Selection, Trace R. Stauble
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Herbivore foraging behavior plays a critical role in shaping grassland structural heterogeneity, with selection often driven by forage biomass and nutritive value. Currently, it is thought that herbivores primarily select areas that are greater in nutritive value, and low in biomass. More specifically, disturbances like fire and grazing have been thoroughly studied showing that recently burned and grazed areas are not only higher in nutritive value but disproportionately selected by herbivores in comparison to undisturbed areas. However, most studies address only narrow ranges of defoliation, comparing intensely defoliated sites (< 10 cm) to those that are either not defoliated or have experienced a much longer time since defoliation, thereby decreasing grazing pressure as biomass increases. However, one of the most widely used methods of defoliation in grasslands, mowing, hasn’t been thoroughly studied for its effects on nutritive value, and how it impacts herbivore selection. Our study aimed to (1) evaluate how mowing treatments—i.e., short (5 cm), medium (18 cm), and tall (>30 cm, unmown)—affect nutritive value and herbivore selection, (2) assess …

Cover Crop Influence On Arthropod Biodiversity And Soil–Water Dynamics In A Semi-Arid Maize–Soybean Sequence Of The Nebraska High Plains, Carlos Eduardo De Oliveira Martins
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
With the expansion of cover crop (CC) use in semi-arid regions, producers in the Nebraska High Plains are increasingly interested in understanding how CCs influence both beneficial arthropods and soil-water within maize-soybean (Zea mays L., Glycine max [L.] Merr.) rotations. Integrating CCs in these systems can enhance soil water availability and beneficial insect activity, but potential trade-offs include higher early-season water use by CCs and the risk of increasing potential pest populations. This thesis addresses these questions through two complementary studies conducted under field conditions near Brule, Nebraska. The first study evaluated the effects of a multi-species CC mixture …

Validation Of Diagnostic Markers And Linkage Mapping In Vitis × Muscadinia Hybrids, Isabella Vaughn
Graduate Theses and Dissertations
The Vitis genus comprises two subgenera, Vitis (2n = 38) and Muscadinia (2n = 40), both cultivated for wine, juice, and fresh-market fruit. Vitis vinifera cultivars produce high-quality fruit but are highly susceptible to diseases endemic to the southeastern United States, while muscadines (Muscadinia rotundifolia) provide exceptional disease resistance, heat tolerance, and environmental adaptability. Hybridizing these subgenera offers a path to combine fruit quality with disease resistance; however, wide Vitis × Muscadinia (V × M) crosses remain difficult due to differences in chromosome number, genetic divergence, and reproductive barriers that reduce fertility and recombination. Recent breeding efforts have introgressed stenospermocarpic …

Evaluating Metamitron Efficacy For Glyphosate-Resistant Palmer Amaranth (Amaranthus Palmeri) Management In Sugarbeet Across The Central High Plains, Abraham Akuoko
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Herbicide-resistant (HR) Palmer amaranth (Amaranthus palmeri S. Watson) is regarded as one of the most prominent weeds within sugarbeet fields across the Central High Plains, with limited chemical control options. Although a few herbicides are available, their use is restrictive due to crop injury concerns and can only be applied at or after the 2–4 true leaf (TL) growth stage, which will provide no control for already emerged weeds. However, Palmer amaranth often emerges between sugarbeet planting and the 2 TL sugarbeet growth stage. Consequently, as of 2023, there were no herbicide options to control Palmer amaranth in sugarbeet …

Horticultural Strategies To Improve Yield And Efficiency For Controlled-Environment Cannabis Production, Michael John Alden
All Dissertations
Controlled-environment cannabis (Cannabis sativa L.) production is a novel horticultural industry due to long-standing federal prohibitions associated with production, distribution, and consumption of this species. Many cannabis production methods are based on legacy knowledge and hypotheses that often contradict standard practices used in the agriculture and floriculture sectors. During this research, several horticultural practices were evaluated, including shoot number manipulation, fertilizer restriction, harvest timing, and photoperiod manipulation. Shoot number manipulation was achieved by repeatedly pinching apical shoots, which reduced reproductive shoot length (cm/shoot) and improved inflorescence:trim ratio, both of which can reduce material cost in production and labor cost …

Citrullus Amarus Drought Tolerance: An Above And Below Ground Analysis, Ben A. Hyland
All Theses
Ever rising environmental temperatures threaten global food security by worsening severity and increasing the occurrence of drought. Commercially cultivated watermelon (Citrullus lanatus), have reduced drought tolerance due to a narrow genetic base caused by breeding for desirable traits such as sweetness, size, and flesh/rind color. Comparatively, the crop wild relative desert watermelon variety (Citrullus amarus), while more drought tolerant than their commercially cultivated relatives (C. lanatus), still require large amounts of water to grow and produce reliable fruit yields. Watermelon root morphology plays a key role in their ability to tolerate drought, with more …

Post-Fire Soil Health Assessment Of The Grasslands And Woodlands In The Semi-Arid Nebraska Sandhills, Stephanie M. Lugo
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Grasslands in the Nebraska Sandhills are shaped by natural wildfires, which help maintain the structure and function of native grasslands. In recent decades, afforestation with ponderosa pine and eastern redcedar has introduced new woodlands that altered the region’s fire dynamics and raised important questions about the effects of wildfire on different vegetation types. As wildfires become more frequent, understanding their impacts on soil health in grasslands and woodlands becomes increasingly important. This study examines the short-term effects of the 2022 Bovee Fire on physical, chemical, and biological soil properties in native grasslands and ponderosa pine and eastern redcedar afforested woodlands. …

Effect Of Microbial Inoculation On Phosphate And Nitrogen Uptake From Dry Soil By Two Grasses With Different Nutrient Acquisition Strategies, Reem Hamdan Alkaabi
Thesis/ Dissertation Defenses
Organic matter and other sources of plant nutritional elements typically enter the soil from its surface, resulting in topsoil having the highest microbial activity, concentration of nutritional elements, and rooting densities. In agricultural systems of the UAE, high ambient temperature triggers rapid evaporation and causes the topsoil to dry. Nutrient uptake from dry soil is very challenging for plants, and topsoil dryness can have a negative impact on plant performance.
Beneficial soil microorganisms mediate plant growth by inducing tolerance against abiotic stresses. Arbuscular mycorrhizal (AM) fungi extend a large network of hyphae that helps the plants to acquire water and …
