Attitudes Toward Transgenic Corn Usage Among Amish & Conservative Mennonite Farmers In Ohio, Scot Long
Journal of Amish and Plain Anabaptist Studies
Mass adoption and planting of genetically modified corn are part of the larger industrialized agricultural production system in the United States. Amish and conservative Mennonite farmers in the Holmes County settlement region offer an alternative production system often characterized by lower usage of chemical inputs, greater implementation of crop rotation, and significantly higher usage of hybrid versus GMO field corn. Moreover, the rationale among Amish/Mennonite farmers toward adoption of GMO (based on “convenience”) or rejection of GMO (based on “too many unknowns”) stems both from cultural diffusion of neighboring farms as well as variable need for nonfarm income. This article …

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Hop (Humulus lupulus L.) is an ingredient in the beer brewing industry that provides beer its flavor and aroma. High demand from the brewing industry has encouraged production outside of the traditional Pacific Northwest, the primary production region. Producers in the Midwest are attempting to grow cultivars adapted to the Pacific Northwest, but environmental differences have caused low yields and changes in secondary metabolite content. To aid producers, a regional breeding program was initiated to develop cultivars adapted to the Midwest. Success of any breeding program relies on the selection of genetically superior parents to generate progeny with the …

Mycorrhizae In Maize (Zea Mays L.) Cropping Systems Respond Differently To Nitrogen Fertilization Under Increasing Crop Rotational Diversity, Morgan R. Mcpherson
Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research
Arbuscular mycorrhizal fungi (AMF) remain a vital obligate symbiont of nearly all plants. It is well established that the symbiosis between AMF and host plant improves plant nutrient acquisition, alleviates abiotic and biotic environmental stressors, defends against plant pathogens, and contributes to overall plant fitness and productivity through modification of the soil habitat. Modifications include increased soil aggregation and stability, carbon sequestration through provision of fungal wall precursors to soil organic matter (SOM) formation, and enhanced nutrient cycling in the mycorrhizosphere. The goal of this dissertation was to assess how AMF respond to nitrogen (N) fertilization regimes in maize cropping …
