Addressing Agricultural Mulch Challenges In Specialty Crop Production, Caleb David Wehrbein

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Agricultural mulches are an essential yield-boosting tool in modern specialty crop production that provide weed suppression, temperature modulation, and moisture conservation functions. Polyethylene plastic mulches are the most widely used agricultural mulch but are not sustainable given their pollutive effect on the environment and challenges associated with recycling. In order to move towards a more sustainable industry, plastic mulch use in agriculture should become more efficient or replaced with more environmentally friendly alternatives. Biodegradable mulches may be a suitable alternative to plastic mulch, but they are often less durable and prematurely degrade in field conditions. Considering this, my dissertation research …

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.

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 …

Horticulture Faculty Publications and Presentations

As a prerequisite for sexual reproduction, gametophyte development is an interesting process involving cell proliferation, differentiation and specialization. Gametogenesis has been extensively explored in model plants, but the regulatory mechanism of gametophyte development largely remains unknown in Cucurbitaceae species. In present study, we have shown that watermelon ClBBM and ClPLT2, two AP2/ERF transcription factors, participated in both male and female gametophyte development. Clbbm and Clplt2 single mutants resembled wild-type phenotypes in both vegetative and reproductive development. But Clbbm/Clplt2 double mutant showed partial pollen abortion and bore less seeds comparing to WT. Our results indicated that the abnormal pollen grains were …
