Evaluate A Personal-Sized Seedless Watermelon Grown In High Tunnels, Wenjing Guan

Midwest Vegetable Trial Reports

Growing personal-sized seedless watermelons in high tunnels is not a common practice in the U.S. However, as high tunnel adoption increases and farmers gain experience in using them for specialty crop production, there is a need to evaluate nontraditional crops to improve crop rotation within these structures. In this study, we evaluated the performance of a personal-sized seedless watermelon grown in a high tunnel system. This seedless watermelon cultivar was selected because of its thin rind, tender flesh, and high sugar content. The combination of these fruit traits may make it particularly attractive for local food markets. Additionally, we compared …

Effect Of Buckwheat And Silage Tarps On Sweetpotato Between-Row Weed Control, Emmanuel G. Cooper, Stephen L. Meyers, Katherine Jennings, Ashley Adair, Kevin D. Gibson, William G. Johnson

Department of Horticulture & Landscape Architecture Faculty Publications

Field studies were conducted on certified organic land in Lafayette and Vincennes, IN, in 2023 to determine the impact of different between-row weed control methods on weed suppression and sweetpotato yield. Between-row treatments consisted of organic buckwheat (108 kg ha−1) broadcast seeded immediately after sweetpotato transplanting followed by silage tarping from 3 wk after transplanting (WATr) through harvest, organic buckwheat (108 kg ha−1) broadcast seeded 3 WATr and terminated 7 WATr, and cultivation as a grower standard. Weed density at 6 WATr was 0, 184, and 162 plants m−2 for the silage tarping, living mulch buckwheat, and cultivation treatments, respectively. …

Starter Transplant Solutions Do Not Improve Cabbage Yield In High-Fertility Soil, Charlie Rohwer, Jesen Hosch

Midwest Vegetable Trial Reports

Starter fertilizers, generally high in phosphorus, are often used when transplanting vegetable crops. However, many small-scale vegetable growers have very high soil phosphorus levels, and phosphorus may be unnecessary in such conditions. Alternatively, enhanced soil microbial activity at transplant may help to make the soil phosphorus more available to the transplants. We tested this by using molasses or high-P fertilizer in the transplant solution when planting cabbage into high-fertility soil. Results indicate no benefit to cabbage from any transplant solution in high-fertility conditions, and detrimental effects from the large amount of molasses used.

Evaluation Of Cantaloupes For High Tunnels, Lewis Jett

Midwest Vegetable Trial Reports

Cantaloupes (Cucumis melo) have potential as a double crop for high tunnel in West Virginia Ten cantaloupe cultivars were evaluated in a high tunnel in 2024 at the WVU Organic Horticulture Farm in Morgantown, WV. The cultivars were established as transplants and planted on black plastic mulch on May 10, 2024. Each cultivar was replicated three times in a randomized complete block experimental design. Harvest commenced approximately 60 days after transplanting and fruit weight and quality attributes were measured. ‘Sugar Cube’ and ‘Savor’ were the highest yielding personal-size melons while ‘Athena’ and ‘Ambrosia’ were the highest yielding >1 …

Our focus is mainly starting vegetables. However, the principles discussed apply to starting herbs and other ornamental annuals and perennials. Online propagation protocols, books on plant propagation, and other Utah State University (USU) Extension resources discuss how to start other unique and less common plants.

Starting Vegetable Seeds Indoors: I. Planning, Wesley Crump, Taun Beddes, Michael Caron, Milena Oliveira

All Current Publications

For many Utah gardeners, starting vegetable seeds indoors offers both an exciting opportunity to experiment with new varieties and a practical necessity for ensuring the successful growth and production of certain crops in their unique environmental conditions. Vegetable gardening involves inherent risks, particularly for the plants, with weather being a significant and largely uncontrollable factor. Because of this, many gardeners are unsure about when to start certain crops and whether the crops should be started indoors or sown directly in the garden. This fact sheet, the first in a series of four, discusses planning considerations when starting seeds indoors.

Performance Of Eight Lettuce Cultivars In A Water Culture System, Ricky C. Young, Hudson M. Cox, Jacob D. Frodge, Mollie K. Mayabb, Brycen C. Shephard, Alireza Rahemi

Posters-at-the-Capitol

Lettuce (Lactuca sativa L.) is one of the most well-known vegetables in the world. About 27 million tons of lettuce were produced in the world in 2022 and global demand for lettuce is increasing steadily, driven by the importance of fiber consumption. Lettuce can be grown in multiple media, including hydroponic systems in a controlled environment agriculture (CEA) system. Growing lettuce in hydroponic systems is an alternative to lettuce production optimization. Since little information is available about lettuce cultivar trials in hydroponic systems, a research project was developed and executed to study the ability of different types of lettuce …

Improving Fertilizer Efficiency In Containerized Nursery Production Through Substrate Temperature Management Techniques, Ashley R. Edwards

LSU Master's Theses

Resource efficiency, particularly regarding mineral nutrients, is a critical factor in the long-term success of the nursery industry. Fertilizer release is controlled by water and temperature in container-grown ornamental nursery production systems. Thus, it was hypothesized that pragmatic management of substrate temperature and moisture could extend the longevity of controlled-release fertilizer (CRF) in a container system. This study was conducted to determine the effect of irrigation scheduling, container color, and stratified substrates on substrate temperature and the subsequent use and longevity of CRF in a crop production setting. ‘Limelight’ Hydrangea (Hydrangea paniculata) liners were planted in either black …

Genome-Wide Association Studies In Lettuce Reveal The Interplay Of Seed Age, Color, And Germination Under High Temperatures, Sookyung Oh, Ezekiel Ahn, Ainong Shi, Beiquan Mou, Sunchung Park

Horticulture Faculty Publications and Presentations

Thermoinhibition, the suppression of seed germination by high temperatures, is an adaptive trait that ensures successful seedling establishment in natural environments. While beneficial for wild plants, thermoinhibition can adversely affect crop yields due to uneven and reduced germination rates, particularly in the face of climate change. To understand the genetic basis of thermoinhibition, we conducted a comprehensive genetic analysis of a diverse panel of Lactuca spp. accessions. Our findings revealed that L. serriola, a wild ancestor of cultivated lettuce, showed relaxed thermoinhibition response compared to cultivated lettuce, suggesting that this trait may have been positively selected during early domestication in …
