Agroforestry education for high school agriculture science : a case study of novel content implementation
(University of Missouri--Columbia, 2017)High school agriculture science programs are recognized as meaningful arenas to reach young agriculture professionals as they gain a foundational understanding of their field. While sustainability is at the forefront of ... -
Biochar and compost application effects on grapevine growth and physiology
(University of Missouri--Columbia, 2017)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Biochar has the potential to be a local and renewable resource produced from waste byproducts that can replenish soils and build fertility. The objective ... -
Canopy recruitment dynamics in naturally regenerated longleaf pine (pinus palustris) woodlands
(University of Missouri--Columbia, 2017)The ecological and cultural values of the longleaf pine (Pinus palustris) ecosystem, in combination with an approximately 97 percent loss in historic range, has led to increasing interest in ecosystem restoration and ... -
Effects of fire and thinning on Kansas oak woodlands
(University of Missouri--Columbia, 2017)Prior to Euro-American settlement, a mosaic of prairie, savanna, woodland, and forest existed within the Forest-Prairie Transition Region of the United States, with anthropogenic fire acting as an important driver in the ... -
Elucidating the role of jasmonate metabolites in jasmonic acid signaling
(University of Missouri--Columbia, 2017)The plant hormone jasmonic acid controls immune responses against insect herbivory and regulates plant development. Jasmonic acid is synthesized upon wounding and herbivory and is converted to many derivatives collectively ... -
Field pennycress management in upstate Missouri
(University of Missouri--Columbia, 2017)Field pennycress has the potential to serve as a cover and oilseed crop. A seed oil content of 25 to 36 percent has created interest in pennycress domestication. This research evaluated management strategies for growing ... -
Flower production and effect of flower harvest on berry yields within six American elderberry genotypes
(University of Missouri--Columbia, 2017)Cultivation of American elderberry (Sambucus canadensis) is increasing in North America for its use in dietary supplements. While the flowers of European elderberry (S. nigra) are commonly consumed as an anti-viral in ... -
High density mapping and quantitative trait loci analysis for fungal diseases in vitis aestivalis-derived 'Norton' and breeding for low palmitic acid in glycine max
(University of Missouri--Columbia, 2017)Vitis aestivalis-derived 'Norton', the official grape of the State of Missouri, is grown in many U.S. regions where V. vinifera production requires extensive pesticide use for fungal disease management. To identify genetic ... -
Identifying bioactive phytochemicals in spent coffee grounds for cosmetic application through global metabolite analysis
(University of Missouri--Columbia, 2017)Annually, more than 6 million tons of spent coffee grounds (SCG) are generated worldwide. The present study explores the possible use of spent coffee grounds as the raw materials for cosmetics industry. The main objective ... -
Integrating nitrogen source and application timing into the management of large patch on zoysiagrass
(University of Missouri--Columbia, 2017)Large patch is the most limiting disease that affects zoysiagrass in the upper transition zone of the United States. Management of this disease requires two to four fungicide applications split between the fall and spring ... -
Mechanical and thermal weed control in organic crops
(University of Missouri--Columbia, 2017)Effective weed control is one of the most yield-limiting factors in organic corn and soybean production. Additionally, the amount of tillage needed to control weeds in organic practice is often criticized for its negative ... -
Multispectral canopy reflectance and digital imaging to determine maturity
(University of Missouri--Columbia, 2017)Soybean breeders and producers may benefit from approaches that can quickly and quantitatively measure soybean developmental stages. To better predict developmental stages, seasonal dynamics of soybean canopies were ... -
Use of non-lethal endpoints to establish water quality requirements and optima of the Topeka Shiner (notropis topeka)
(University of Missouri--Columbia, 2017)Water quality influences growth, development, and physiology of aquatic vertebrates. Current criteria on water quality assessments are primarily based on lethal level experiments (e.g. LC50 tests), which are poorly suited ...
