USU Student Organic Farm Newsletter

As of now, nearly all of our produce for our shares is coming from one hoop house. We are at the mercy of the weather at this time regarding our field crops. The cold weather of the past week has resulted in much smaller harvest of asparagus than we had hoped. Next week will hopefully see a bundle of asparagus back in each of your shares.

Are Consumers Willing To Pay More For Sustainable Products? A Study Of Eco-Labeled Tuna Steak, Guzhen Zhou, Wuyang Hu, Wenchao Huang

Agricultural Economics Faculty Publications

A high demand for seafood leads to overfishing, harms the long-term health of seafood stocks, and threatens environmental sustainability in oceans. Sustainability certification is one of the major sustainability movements and is known as eco-labeling. For instance, in the tuna industry, leading tuna brands have committed to protecting sea turtles by allowing the tracing of the source of their tuna “from catch to can.” This paper relies on an Internet survey on consumers from Kentucky conducted in July 2010. The survey investigates household-level tuna steak (sashimi grade) consumption and examines consumer preferences for eco-labeling (“Certified Turtle Safe” (CTS) in this …

Behavioral Determinants Of Biofortified Food Acceptance: The Case Of Orange-Fleshed Sweet Potato In Ghana, Chinonso E. Etumnu

Master's Theses

Biofortified foods are being introduced in sub-Saharan Africa as an important strategy to help address micronutrient malnutrition. However, there has been little research on factors that could play decisive roles in their successful introduction. This paper investigates the determinants of consumer acceptance of biofortified orange-fleshed sweet potato (OFSP) using data from a choice experiment conducted in Ghana. I find that OFSP is preferred to traditional white-fleshed and yellow-fleshed sweet potatoes as indicated by consumers' marginal willingness to pay for the three varieties. I also find that respondents' socio-economic characteristics do not have a significant effect on consumer acceptance of OFSP. …

A Multiple‐Scale Assessment Of Long‐Term Aspen Persistence And Elevational Range Shifts In The Colorado Front Range, Mario Bretfeld, Scott B. Franklin, Robert K. Peet

Aspen Bibliography

Aspen forests and woodlands are some of the most species‐rich forest communities in the northern hemisphere. Changing climate, altered disturbance regimes, land use, and increased herbivore pressure threaten these forests both in Eurasia and North America. In addition, rapid mortality dubbed “Sudden Aspen Decline” is a concern for aspen's long‐term presence in the western United States, especially Colorado and Utah. Yet it is still unclear whether aspen is persistent or declining at the landscape scale. We assessed aspen persistence at different spatial scales in the Colorado Front Range by resampling 89 plots containing aspen from among 305 vegetation plots sampled …

North Central Extension Risk Management Education Center, Christine Lockert, Bradley D. Lubben

Cornhusker Economics

After peaking over $120 billion in 2013, U.S. net farm income fell to $56 billion in 2015 with projections of $54 billion for 2016, the lowest level since 2002 (USDA Economic Research Service). The large drop from 2013 to 2016 after nearly a decade of strong growth in agricultural income presents a substantial challenge to agricultural producers and an increased need to carefully manage risk on the farm or ranch.

From Empty Lot To Garden Plot: Urban Agriculture In Chula Vista, Jennifer E. Gutierrez

Undergraduate Honors Theses

This project is an exploration of how agriculture can be incorporated into the fabric of the city of Chula Vista, which has both uniquely urban and suburban areas. The proposal is to integrate agriculture as a design tool to reconnect to the city’s agricultural past and as a model for cities of the future. First, I discuss Chula Vista’s history and contemporary context, including demographics. I review the existing urban agriculture policies Chula Vista has and compare them to other cities in California. The second part of the project is concerned with how to choose and develop a site for …

Impacts From The Use Of Antibiotics In Livestock: Methods Of Transmission Of Antibiotic Resistance From Livestock To Humans, Kristin M. Walden

Biology: Student Scholarship & Creative Works

Antibiotic use in livestock production has been around since the 1950s. Antibiotic feed is used in livestock and other meat producing animals for three reasons: illness prevention, illness treatment, and growth promotion. Unfortunately, since the time that antibiotics were first invented, antibiotic resistant bacteria have become a threat to public health. There are many studies showing methods of transmission of antibiotic resistance from livestock to humans. Antibiotic resistance can spread from livestock to soil, water, insects, and food, which ultimately comes into contact with humans. A proposed study to measure antibiotic resistance when eliminating antibiotic feed will provide a hypothesis …

Determining The Most Efficient Type Of Growth Light For An Aquaponics System Using Yellow Lantern Chilies (Capsicum Chinense), Travis Mceachern

Undergraduate Theses

Abstract

Aquaponics, a type of urban agriculture, shows potential to produce large amounts of food with little water and land requirements. Thus, aquaponics could help address the issue of feeding the growing worldwide population. However, multiple challenges, both technical and economical, are associated with aquaponics, making large-scale implementation of these systems difficult – these systems can require tremendous amounts of energy. This study sought to determine the most efficient types grow lights in aquaponics systems by comparing the growth rates of yellow lantern chilies (Capsicum chinense) when grown under four different types of growth lights: light-emitting diode (LED), …

Large-Plot Field Studies To Assess Impacts Of Newer Insecticides On Non-Target Arthropods In Western U.S. Orchards, Peter W. Shearer, Kaushalya G. Amarasekare, Steven P. Castagnoli, Elizabeth H. Beers, Vincent P. Jones, Nicholas J. Mills

Agricultural and Environmental Sciences Faculty Research

The non-target impacts of two reduced risk insecticides, chlorantraniliprole and spinetoram, were evaluated for two years in Oregon pear and California walnut orchards. Experiments were conducted in large replicated plots (approximately 0.25–0.4ha) to assess the impact of these two insecticides on natural enemies of secondary pests when applied against codling moth, Cydia pomonella. Cumulative insect days (CID) of secondary pests and natural enemies were calculated from leaf samples, plant volatile traps, beat trays or cardboard trunk bands. Ratios of natural enemies and prey were also calculated. Results from these field studies demonstrate that applications of chlorantraniliprole can reduce abundance of …

A Brief History Of Corn: Looking Back To Move Forward, Jon Derek Pruitt

Doctor of Plant Health Program: Dissertations and Student Research

Maize was domesticated from teosinte in Mexico some 7,000 to 10,000 years ago and quickly spread through the Americas. It has become one of the most important crops at a local and global level. Two types, Northern Flint corn and Southern Dent corns provided the basis of the genetic background of modern maize hybrids. The development of hybrids, first double-cross and later single-cross hybrids, along with a transition to high input farming provided huge yield increases, which have continued to improve with improving technology.

Increase in maize production also caused a rise in Western corn Rootworm (Diabrotica virgifera virgifera …

Unemployment In Ag-Dominant States During And After The Great Recession, Anil Giri, Kyle Lovercamp, Sankalp Sharma

Cornhusker Economics

The United States and the world saw a major economic decline at the end of 2007. A recession is defined as two or more consecutive quarters of negative economic growth. This one was so severe that it was given a name -- The Great Recession --and called the worst economic crisis since The Great Depression. In the United States more than 7.5 million jobs were lost, doubling the unemployment rate (Grusky, D. B. et al, 2011). There have been several investigations into the causes of the economic recession. The general conclusion is that there were complex and interlinked factors behind …
