Aversion Properties Of Retrorsine, Retrorsine Nitrogen Oxide And Frosted Senecio Latifolius, Leendert D. Snyman

Poisonous Plant Research (PPR)

Two pilot trials, investigating the aversive properties of retrorsine and retrorsine nitrogen oxide and that of frosted Senecio latifolius, were executed. Retrorsine and retrorsine-NO (the toxic principles of Senecio retrorsus), unlke sceleratine-NO (the toxic principle of another hepatotoxic pyrrolizidine alkaloid containing plant, namely S. latifolius), were not capable of establishing aversion when given to a sheep. Frosted S. latifolius given to a sheep also did not induce aversion. However, a sheep averted to S. latifolius (non-frosted) refused eating frosted S. latifolius.

Sceleratin Nitrogen Oxide As Aversive Agent In Conditioning Livestock To Avoid Senecio Latifolius, Leendert D. Snyman

Poisonous Plant Research (PPR)

Sceleratine nitrogen oxide, when administered together with a dichloromethane extract of Senecio latifolius, successfully conditioned cattle and sheep to avoid milled freeze dried S. latifolius mixed with maize meal. This treatment was effectively applied in conditioning steers to refuse eating S. latifolius grown in pots.

Isolation Of The Toxic Principle Of Senecio Latifolius By Means Of The Sensory Receptors Of Sheep, Leendert D. Snyman

Poisonous Plant Research (PPR)

The aversive substance of Senecio latifolius was isolated by means of the sensory receptors of sheep averted to S. latifolius. Chemical fractions refused due to the presence of the aversive substance sensed by the sheep were fractionated until a purified substance had been isolated. Nuclear magnetic resonance (NMR) analysis of the purified substance showed it to be sceleratine nitrogen oxide, the toxic principle of S. latifolius.

Civil and Environmental Engineering Faculty Publications

Numerous strategies have been suggested to reduce dependence on synthetic products, such as physical, microbial, and natural methods. Among the natural remedies, plant extracts have emerged as a popular option owing to their eco-friendly character, ease of degradation, and harmless nature to humans. In our study, we used the acetone and hexane extracts of Rhaphiolepis indica fruit to combat two fungal pathogens that were isolated from infected bean plants and showed root rot symptoms. The two pathogens were confirmed to be pathogenic by pathogenicity assays conducted in vivo. The morphological and molecular identification by ITS-region sequencing revealed that the two …

Association Between Financial Education, Affective And Cognitive Financial Knowledge, And Financial Behaviors, Lucy M. Delgadillo, Yoon Lee

Applied Sciences, Technology and Education Faculty Publications

Using data from the 2018 National Financial Capability Study, this paper examined the relationship between financial education participation and affective and cognitive financial knowledge. Involvement in financial education yielded statistically significant associations between affective and cognitive domains. The results showed that participation in financial education was associated with both cognitive and affective financial knowledge as well as long-term financial behaviors. The findings supported the case for life-long learning of financial education for young adults, Blacks and Hispanics, and women. One important implication was the need to include both the affective and cognitive domains when teaching or researching financial education.

Balancing Food Security And Environmental Sustainability By Optimizing Seasonal-Spatial Crop Production In Bangladesh, Man Li, Zhe Guo, Wei Zhang

Applied Economics Faculty Publications

The intensification of crop production has been identified as one of the major drivers of environmental degradation. While significant advances could still be made with more widespread adoption of sustainable intensification technologies that address the agronomic efficiency of nitrogen fertilizers, the dynamic use of agricultural land across seasons and associated crop-specific responses to fertilizer applications have so far been largely overlooked. This paper explores the potential for improving the economic-environmental performance of crop production through spatially integrated modeling and optimization, as applied to Bangladesh. Results show that per-billion-Taka nitrogen loss from soil would decline by 83% from the baseline level …

Supporting Farmer Adoption Of Sustainable Bird Management Strategies, Catherine A. Lindell

Human–Wildlife Interactions

Pest birds cause substantial and costly damage to crops. Managing birds is complex because (1) they are highly mobile, (2) they habituate quickly to many deterrents, (3) some species provide benefits to farmers by deterring and consuming pest insects, rodents, and other birds, and (4) birds are highly valued by many people. Thus, farmers have many issues to consider when developing bird management strategies. Here I discuss recent work indicating that farmer adoption of sustainable agricultural practices is more likely when practices are effective, clear guidelines for implementation are available, implementation is relatively easy, and when practices are linked, in …

Untangling The Economic And Social Impediments To Producer Adoption Of Organic Wheat, Donya L. Ralph-Quarnstrom

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Consumer demand for organic products has shown double-digit growth in recent years encouraging the development of a wider range of goods (Greene, 2017). Americans with an annual household income under $30,000 actively purchase organic foods at nearly the same rate as households with over $75,000 in annual incomes, 42% versus 49% (Greene et al., 2017). Previous research observed the adoption of organic farming practices on a combination of different grains, fruits and vegetables, meat, and dairy products from across the globe. However, this is the first study to examine the adoption of organic wheat in the Western U.S. By addressing …

Entrepreneurs' Perceived Factors Of Success And Barriers-To-Entry For Small Business And Farm Operations In Rural Paraguay, Braden J. Jensen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Both agriculture and nonagriculture activities are important for Paraguay's economy and its rural development plan. Ensuring opportunity for successful enterprise creation and expansion will facilitate new business entrance, while also growing rural economies. Past research has identified many factors that contribute highly to business and farm operation success, though little information exists about the perceptions of would-be entrepreneurs.

This study analyzes perceptions and characteristics of young, would-be entrepreneurs and agriculture producers in rural Paraguay to better understand their views of business/farm success and hurdle factors. Results suggest that increased experience, education and business exposure will decrease perceptions of many barrier …

Nutritional And Economic Analysis Of Small-Scale Agriculture In Imbabura, Ecuador, Jake Erickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Intervention projects in the developing world normally aim to satisfy either the nutritional needs of a group, or advancing the economic stability, but not both. One of the many issues that may arise by narrowly focusing and creating an aid program is that although a group may be fed, they are not equipped to mitigate risks that will arise after project completion and thus continue or revert back to a malnourished state. A bridge is required to join the economic and nutritional programs to create aid interventions that are sustainable past the point of donor separation.

This paper proposes the …

Can Pastoral Linkages To Livestock Markets Be Sustained In Southern Ethiopia?, D. Layne Coppock

D. Layne Coppock

The PARIMA project has facilitated collective action, empowerment of women, and increased involvement in livestock marketing among pastoralists on the Borana Plateau since 2001. Fifty-nine collective-action groups formed by PARIMA and her partners have been recently merged into market-oriented cooperatives, consistent with government policy. We used focus groups and participatory appraisals to assess the extent that market linkages have been sustained since previously reported in 2006. The markets have been growing, but are volatile. Members report they need access to early warning and livestock market-information systems, as well as more capital, to promote trade. Export firms have imposed added conditions …

Consumer Surplus And Economic Rent Estimates Of Recreation Value: An Empirical And Theoretical Comparison, Eric R. Meale

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The consumer surplus and economic rent methods of resource valuation were applied to boating recreation in Utah. Total consumer surplus and economic rent values were estimated for twenty-four boating sites. These values incorporate the relationship existing between the variable use cost and the units of activity associated with the site.

Data were collected by a mail survey directed to boaters during the 1973 boating season. Approximately 1,408 questionnaires were analyzed. Additional data were collected from the Utah Division of Parks and Recreation.

Economic rent and consumer surplus were compared by using a common mathematical model and empirical observation. The concepts …

Economic (Linear Programming) Model Of The Farming Region Served By The D.M.D.A. Irrigation Company, Delta, Utah, Francisco Zarzalejo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objectives of the study are to create a linear programming model of the study area in order to estimate changes in benefits when water delivery system losses are assumed to be affected by shifting between rotation, demand and continuous flow management systems,

Approximately 7,000 acres are included in the program model and the estimated potential "gains" or benefits from distribution system loss "savings" due to more efficient delivery range from $6,000 to _ $12,000 per season. This result is influenced by the facts that the - loss estimates are hypothetical and the system studied is in an area …

A History Of The Utah Extension Service, 1888-1950, Karen Juchau

The program began with college instructors holding Farmers' Institutes and schools and expanded into a state-wide system of agricultural and home extension work carried on by specially appointed county agents in each county. The purpose …

Economics Of Wool Marketing In Utah, E. Jay Berry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Since the beginning of history the wool of sheep has been used by the human race. Its chief use has been and still is for clothing. Also, it is widely used for blankets, upholstery, carpets, and numerous other products.

The wool industry is important to the state of Utah, which was the sixth largest producing state in the United States in 1958. Wool growers in Utah received approximately $7,897,000 in sales proceeds and government payments for wool sold during the 1958 marketing year (12).¹
