Yield And Size Of Direct-Seeded Onions In Southern Minnesota With Three Row Arrangements, Charlie Rohwer, Jesen Hosch

Midwest Vegetable Trial Reports

Dry bulb onions are a minor crop in Minnesota, grown mostly by small-scale market farmers. Most onions are grown as transplants, likely due to the shorter growing season and easier weed control. We undertook a study to understand yield potential of four direct-seeded (unpelleted) onion varieties, and the impacts of between-plant spacing at a single population on onion yield, size, and size variability. Four onion varieties were seeded on 9 April using a Jang JP6 push seeder in one of three row arrangements: four evenly-spaced rows, two double-rows, or three rows with seeds scattered in the middle row. All were …

Evaluation Of Eight Parthenocarpic Slicing Cucumber Cultivars And Four Production Systems In Southwest Michigan In 2025, Ben Phillips

Midwest Vegetable Trial Reports

In the machine-harvested pickling cucumber system, parthenocarpic (parth) varieties make up about 50% of the market, and is growing. The seed cost is higher, but this is offset by not needing to contract or truck bees and an increased yield when planted at half the population of standard varieties. Additionally, they hold their shape and size better when moisture and temperatures fluctuate, reducing docked payments from graders. In pickling cucumbers, a breakeven yield is approximately 250 bushels per acre with a plant population of 30,000 plants per acre. Plant populations can play a strong role in economic viability, as demonstrated …

Insecticide Resistance Testing In Cluster Caterpillar (Spodoptera Litura) From Population Across Wa, Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

A study by the Department of Primary Industries and Regional Development (DPIRD) was undertaken with the aim to better manage insecticide resistance in the cluster caterpillar (Spodoptera litura). Cluster caterpillar is an endemic armyworm species in WA, particularly in the State’s north, which affects a wide range of host plants including table grapes, capsicums, aubergine, cow peas, mung beans, maize, cotton and asparagus. The work was undertaken in response to field reports, from northern Western Australian horticultural regions, that some commonly used insecticides no longer provide adequate control, raising concerns that resistance has developed to some insecticides.

Root-Knot Nematodes In Western Australian Horticulture, Department Of Primary Industries And Regional Development, Western Australia

Horticulture factsheets

Root-knot nematodes (Meloidogyne species, RKN) are unsegmented round worms which are usually invisible to the naked eye, but the galls they produce in infested plant roots are often easy to spot. RKNs are plant-parasitic with a broad host range, which includes vegetables, field crops, tree and vine fruits, ornamentals, pastures and some weed species.

Root-knot nematodes reduce yields of many horticulture crops, including carrot, potato, sweet potato, tomato, capsicum, pumpkin, zucchini, avocado, grapes and lettuce. RKNs favour the sandy soils common throughout the south-west of Western Australia’s (WA’s) horticultural area.

Factors Affecting Diet Selection In Sheep Fed Endophyte-Infected Toxic Fescue, Jordan Thomas, Ronelson Stinfil, Kenneth P. Coffey, Christine C. Nieman, Derico Setyabrata, Shawna Weimer

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Tall fescue (Lolium arundinaceum (Schreb.) S.J. Darbyshire) infected with toxin‑producing fungi can induce fescue toxicosis in grazing ruminants, reducing performance and altering forage intake. Chemical compounds in red clover (Trifolium pratense), such as biochanin A, have been proposed to mitigate these effects by improving palatability and blood vessel relaxation. This study examined whether the inclusion of ground red clover (GRC), either alone or in combination with hydroxypropyl methylcellulose (HPMC) and polyethylene glycol (PEG), affected voluntary diet selection in lambs offered toxic fescue. Thirty‑three lambs were housed individually and assigned randomly to one of four diets: (1) toxic …

Carbon Source-Induced Changes In The Transcriptional Landscape Of Novacetimonas Hansenii, Bashir A. Akhoon, Jordan Corley, Jia W. Tan, Roberta Magnani, Rachel R. Schendel, Andrew Lipton, Carlos M. Rodriguez Lopez, Kendall R. Corbin

Horticulture Faculty Publications

Novacetimonas hansenii is a model organism for bacterial cellulose (BC) production, a biopolymer with broad industrial applications. To better understand its carbon source-dependent metabolism, we conducted the first time-resolved transcriptomic analysis of N. hansenii ATCC 23769 grown on five carbon sources (glucose, fructose, mannitol, galactose, and sucrose) across five time points (24–120 h). Glucose, fructose, and mannitol supported growth and efficient BC production, whereas galactose and sucrose resulted in poor yields, likely due to limited transport and enzymatic capacity. Solid-state NMR revealed that cellulose crystallinity and polymorphism were carbon source-dependent, with reduced bcsD expression correlating with lower crystallinity. Transcriptomic profiling …

Horticulture Faculty Publications

Eggplant exhibits a diverse range of fruit colors, making it an excellent model for studying fruit pigmentation and its genetic regulation. While genes responsible for green and photosensitive purple fruit have been identified, the genetic basis of the nonphotosensitive (NPS) fruit trait in eggplant has remained elusive. In this study, we characterized a major quantitative trait locus (QTL), SmNPS10.1, on chromosome 10 using QTL-seq. By combining linkage-based gene mapping with progeny testing, we fine-mapped SmNPS10.1 to a 33.58-kb interval, within which we identified SmMYB113, an R2R3-MYB transcription factor that regulates anthocyanin biosynthesis, as the candidate gene. Sequence analysis …

Extending The Fruiting Season With Container Grown Primocane-Fruiting Blackberries Grown In A High-Tunnel, Edwin James Tucker Iii

Graduate Theses/Dissertations

Blackberry production has become an important part of many small fruit orchard operations because they’re easy to grow, produce a large crop, and sell well at market. The current blackberry season in Missouri extends from mid-June to mid-August, depending on the cultivar chosen. This fruiting season is common for floricane-fruiting blackberry cultivars (cultivars that fruit on one-year old canes). Primocane-fruiting blackberry, or blackberries that fruit on current season growth, have the potential to further extend the harvest season of blackberry into September and October especially if grown in a high-tunnel. This study had two objectives. The first objective was to …

Soil Solarization As A Sustainable Approach To Manage Weeds And Arthropod Pests, And Its Effects On Soil Nitrate And Lettuce (Lactuca Sativa L.) Yield In Kentucky And Tennessee High Tunnels, Paula Luize Lessmann

Theses and Dissertations--Plant and Soil Sciences

The use of high tunnels (HTs) has increased over the past 15 years, with more than 1,700 and 700 structures currently in Kentucky and Tennessee, respectively. High tunnels are widely used to extend the growing season and protect specialty crops from adverse weather conditions. However, continuous production and limited crop rotation within HTs can lead to the accumulation of soilborne pathogens, plant-parasitic nematodes, arthropod pests, and weeds, ultimately reducing crop yield and quality. Management of these biotic issues is particularly challenging in HTs due to limited pesticide options compared to open field production. Soil solarization, a non-chemical method that uses …

A Novel 3d Imaging Approach To Study Evolutionary Innovations In Solanaceae Inflorescences, Devin L. Jackson, Joonseog Kim, Wenheng Zhang Dr.

UROP Posters

Understanding the relatedness of angiosperms and the evolution of their inflorescence remains challenging, as these structures are highly modified and prone to convergent evolution. The current research describing inflorescence architecture, whether genetically or morphologically focused, typically relies on text based explanations, 2D images, or 3D based models created with CAD modeling software. This creates a disparity in the reader's understanding of these models since descriptions rely heavily on the author's interpretation of the inflorescence. The goal of our study is to bridge this disconnection by producing anatomically and color-correct 3D inflorescence models using Solanaceae flowers that readers can explore directly, …
