Structural Change Of The Western United States Alfalfa Hay Market And Its Effect On The Western United States Dairy Industry, Joseph Patrick Cann

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Alfalfa is the fourth largest commodity grown in the Western U.S., representing 20% of the crop acreage over the past twenty years. In the last five years alfalfa hay price has doubled from what it was previously, indicating a possible structural change in the market. This research project was completed to test for this structural change using econometric analysis of the important demand components of alfalfa price. In addition to this, simulations of an average Utah dairy were completed to examine which ratio of forage crops provided the highest economic return to the operation.

To analyze the structural change of …

Delay Of Bud Break On 'Edelweiss' Grapevines With Multiple Applications Of Amigo Oil And Naa, Benjamin A. Loseke

Department of Agronomy and Horticulture: Dissertations, Theses, and Student Research

‘Edelweiss’ is an important grape cultivar grown in the Midwestern part of the USA. This grapevine is tolerant to extreme winter temperatures which can be experienced in the areas where it is most widely grown. ‘Edelweiss’ is one of the earliest cultivars in the vineyard to break bud, making it very susceptible to late spring freezes. The primary buds of ‘Edelweiss’ produce a significant amount of fruit, while unlike many other hybrids, the secondary and tertiary buds will have little to no yields, thus making it important to protect the primary buds from a late freeze. The objective of this …

Monitoring Citrus Nutrition In The Rio Grande Valley For Fertilizer Recommendations, Iram Lopez

Theses and Dissertations - UTB/UTPA

Macronutrients such as the N, P, K, Na, Ca, Mg and some of the micronutrients (Zn, Fe, Mn, and …

Spreading The Char: The Importance Of Local Compatibility In The Diffusion Of Biochar Systems To The Smallholder Agriculture Community Context, Laura C. V. Munoz

Pomona Senior Theses

This thesis enters the context of smallholder agriculture communities in the developing world. It explores the potentials of biochar and what biochar systems could bring to the smallholder communities while simultaneously bringing environmental benefits. It then acknowledges the challenges of diffusion –the spreading of an unfamiliar innovation. It seeks to answer the question of what will make diffusion of biochar systems more successful in the smallholder context, fixating on the characteristic of compatibility as well as the role local community members can play in making a new biochar system more visible to the rest of the communities.

Stacking Of A Stearoyl-Acp Thioesterase With A Dual-Silenced Palmitoyl-Acp Thioesterase And Δ12 Fatty Acid Desaturase In Transgenic Soybean, Hyunwoo Park, George L. Graef, Yixiang Xu, Patrick Tenopir, Thomas E. Clemente

Department of Agronomy and Horticulture: Faculty Publications

Soybean (Glycine max (L.) Merr) is valued for both its protein and oil, whose seed is composed of 40% and 20% of each component, respectively. Given its high percentage of polyunsaturated fatty acids, linoleic acid and linolenic acid, soybean oil oxidative stability is relatively poor. Historically food processors have employed a partial hydrogenation process to soybean oil as a means to improve both the oxidative stability and functionality in end-use applications. However, the hydrogenation process leads to the formation of trans-fats, which are associated with negative cardiovascular health. As a means to circumvent the need for the hydrogenation process, genetic …

Phenological Relationships Of Nesting Barn Swallows In A Swallow-Fly-Cattle System And Their Potential Role In Suppression Of Pest Flies In A Warming Climate, Claire Stuyck

All Theses

Conservation efforts for birds that provide ecosystem services in agricultural systems require management approaches that cross disciplines. This information is communicated through a variety of outlets but rarely in ways that interface effectively with normal management approaches. The disconnect between agriculture and wildlife conservation reduces the likelihood that ecosystem service benefits will be realized. One understudied ecosystem service provided by birds such as barn swallows (Hirundo rustica) is their role in suppression of flies that are pests to livestock. Climate change, however, may differentially affect flies that respond largely to temperature, and swallows that migrate and respond to photoperiod and …

Genome-Wide Analysis Of The Variation In Host Genetics In Response To Experimental Challenges With Porcine Circovirus 2b, Taylor B. Engle

Department of Animal Science: Dissertations, Theses, and Student Research

Porcine circovirus is the primary causative agent responsible for inducing a group of associated diseases known as porcine circovirus associated diseases (PCVAD), which can have detrimental effects on production efficiency as well as lead to mortality. The variation in host genetics plays a role in the ability to initiate an effective immune response. The objective of this research was to identify major genetic variants and genes that influence immune response and PCVAD susceptibility. Commercial crossbred pigs (n=974) were experimentally infected with a PCV2b strain to analyze genetic sources of variation in PCVAD susceptibility. The strain used for experimental infection was …

Biopesticide Use In Ipm For Low Desert Vegetable And Fruit Production, Jeremy Wagnitz

Doctor of Plant Health Program: Dissertations and Student Research

Like most other agricultural areas, the low desert valleys of the southwestern United States experience issues with crop pests. Although the arid environment is not suitable for some pests, others thrive in microclimates that develop in each individual irrigated field. These crop pests whether they are insects or pathogens must be managed in a sustainable and environmentally friendly way. Throughout the past 50 to 60 years there has been an over-reliance on synthetic pesticides to manage these issues in agriculture. This over-reliance has allowed crop pests to develop resistance to many of these control products. Due to the development of …
