Greenhouse Aquaponics: Custom Aquaponic Systems At Home, Jesse L. Blanchard, David G. Hyatt, Jennie Popp, Leah English

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Taking advantage of inherent natural systems, aquaponic practices hold the potential to serve as an educational, sustainable, and profitable hobby for home gardeners facing common constraints such as temperature, space, and pests. The goal of this research was to assess the feasibility of implementing a small scale (4,542-liter) home -based aquaponic system in a small (48.768 square meter) greenhouse to produce fresh produce and fish protein. System construction and maintenance costs were compared to the value of crops and fish produced to determine whether this aquaponic system is a feasible option for the home grower. It was hypothesized that this …

Determination Of Optimum Harvest Date For Winter Malting Quality Barley In Northwest Arkansas, Paul Wolf, David Moon, Richard Esten Mason

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Due to the strict quality requirements, only 10% of worldwide barley is used for malting, though malting quality barley comes with a price increase of up to 50% or greater. With the craft brewery industry growing in Northwest Arkansas there is a growing demand for locally sourced malt quality barley. However, data are lacking regarding production practices for barley in Arkansas. The optimal harvest date for malting quality barley is at physiological maturity. This is because many of the malting traits (such as germination energy) decline as harvest is delayed, which make it difficult to meet the criteria for malting …

Consumer Perceptions Of Labeling Claims On Poultry Products, Sarah Townley

Agricultural Education, Communications and Technology Undergraduate Honors Theses

An increasing number of consumers wants more knowledge of how the food they eat is produced, and specifically, how animals used in the production of their food are raised. One method consumers use to become more aware of production practices behind the food they purchase and consume is simply reading food labels. Labeling claims can be defined as textual, pictorial, graphic, or symbolic representation that either explicitly states or implies that a food product has a specific set of properties supported by a certification process. The purpose of this study is to gather data regarding consumer knowledge and understanding of …

Classifying Interdependencies In The Food And Agriculture Critical Infrastructure Sector, John Doerpinghaus

Graduate Theses and Dissertations

This work classifies examples of infrastructure interdependencies found in the food and agriculture critical infrastructure sector. Interdependencies are identified through an examination of rice and poultry agriculture throughout the state of Arkansas. The subtleties of interdependence examples in the food and agriculture sector are inadequately captured by the well-studied interdependence classification taxonomies. Through 39 interviews, we develop an understanding of the subtle temporal, geographic, and productivity scales of interdependence in over 100 examples and present five new, distinct classifications of interdependence: (1) dynamic physical, (2) dynamic geographic, (3) deadline, (4) delay, and (5) human, economic, and natural resource interdependencies. An …

Assessing A Peer Mentor Program In An Honors College Of Agriculture, Isabel Whitehead

Graduate Theses and Dissertations

The purpose of the study was to assess mentees’ experiences in a peer mentor program in an honors college of agriculture and to determine which factors impact mentees’ ability to relate to their peer mentor based on the theory of homophily and interpersonal attraction. Colleges of agriculture are encouraged to examine which determinants impact students’ decisions to enter agri-science programs, what draws students to postsecondary agricultural programs, and to try recruiting underserved individuals into higher education to fulfill open employment opportunities for diverse, skilled, and globally competent individuals (Goeker, et al., 2015; Stripling & Ricketts, 2017). Peer mentoring is often …

Social Interactions Occurring During An Introductory College Of Agriculture Course, Brittany Renea Leek

Graduate Theses and Dissertations

With the development of the internet, today’s students no longer are confined to the resources only found in their classrooms or public libraries and have been given the ability to gain access to virtually unlimited quantities of information on the topics or events they are discussing in their class rooms and with their peers. The use of technology for communication and education is rapidly changing, but the challenges of technology-driven learning opportunities rest on questions of access and use. There is a need to determine whether students use these methods (i.e., technology based) to more prevalently communicate today. The primary …

Preservice Agricultural Education Teachers And Secondary Education Teachers’ Self-Efficacy And Professional Identity, Hailey Gates

Graduate Theses and Dissertations

During the nineteenth century, a decision was made to separate the preparation of agricultural education teachers from their elementary and secondary counterparts (Hearings, 1908; Heren & Hillison, 1996; Hillison, 1986). The majority of land-grant universities and colleges have continued to prepare agricultural education preservice teachers within the college of agriculture, separate from other secondary education preservice teachers in the college of education (Myers & Dyer, 2004). Despite the differences among content disciplines, teachers who possess a strong sense of self-efficacy and professional identity have higher success rates in the classroom when it comes to collaboration, involvement, and student achievement (Ashton …

Evaluating The Impact Of An All-Vegetable Protein Supplement Containing Fat Emulsifiers And Probiotics On Broiler Performance, Jordan Weil

Graduate Theses and Dissertations

Currently, several niche markets, such as organic and “all natural”, are marketed within the poultry industry. However, little research has been undertaken to determine the cost-effectiveness of poultry diets used to produce chicken within these markets. Specifically, the economics and resulting profits associated with raising chicken with antibiotic-free, all-vegetable (AV) diets are not evaluated. As national chain restaurants such as Chick-fil-A and Panera Bread begin to mandate poultry suppliers raise chicken without antibiotics and use AV diets, it becomes increasingly important to evaluate the economics for integrators. Given the rapidly changing feeding strategies necessary to respond to consumers’ and wholesalers’ …

Developing Sustainable Rice Production Through Image Classification, Parker R. Fitzgerald

Industrial Engineering Undergraduate Honors Theses

The agricultural industry’s continued success is critical to our future. However, many agricultural practices—specifically rice farming—are currently based on unsustainable methods. The processes used in rice farming consume water at an unsupportable rate, and, consequently, are serious contributors to rising emission levels. Several alternative growing methods have been introduced, and one of the most promising candidates is Alternative Wetting and Drying (AWD). An obstacle encountered by proponents of these methods comes in implementation. Studies have shown AWD is more successful in fields with higher leveling precision. The research in this study works to create a stepping stone for farmers to …
