Evaluating Economic Impacts Of Switchgrass Harvest Time, Nathanial Elsworth Cahill
Evaluating Economic Impacts Of Switchgrass Harvest Time, Nathanial Elsworth Cahill
Graduate Theses and Dissertations
This thesis deals with cost of production for cellulosic energy crops of switchgrass, miscanthus, and energy sorghum. The first chapter explains the rationale for development of decision support software called Energy Crop Analysis & Planning (ENCAP) and Switchgrass Harvest Date, Yield, Nutrient Removal Estimator (SHYNE). The second chapter examines harvest date implications on yield, nutrient removal, opportunity cost of modified sale dates, and post-harvest storage losses. This harvest date analysis leads to a profit maximizing harvest date from the perspective of the producer. While this harvest date may be optimal for the producer, biorefineries may be interested in sourcing switchgrass …
Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Local Food And Agriculture Awareness: The Literacy Of Local Produce And Agriculture In Northwest Arkansas, Kyle Colton Flynn
Graduate Theses and Dissertations
The Center for Disease Control and Prevention (CDC) suggests that adolescents and children, both male and female, are failing to meet the daily fruit and vegetable consumption requirements (Kim et al., 2011; Upton et al., 2012; Harris et al., 2012). Other studies have shown that with increased exposure and availability of produce, students (K-5) tend to consume more fruits and vegetables (Cullen et al., 2009; Evans et al., 2012). The purpose of this study is to identify whether Northwest Arkansas eleventh grade high school students possess experience and knowledge of local produce and agriculture. Out of 1054 students enrolled at …
Enhancing Soybean Profitability Using Portfolio Theory, Osemenkhian Cynthia Onyechere
Enhancing Soybean Profitability Using Portfolio Theory, Osemenkhian Cynthia Onyechere
Graduate Theses and Dissertations
The purpose of this study was to estimate the effect of utilizing portfolio theory on producers' profitability in the production of soybeans in three test locations - Keiser, Marianna and Rohwer - in Arkansas. The study used empirical yield data, their variances and covariances over a nine year period (2002-2010) in selecting a portfolio of soybean varieties that maintains or increases yield while minimizing the yield risk. Furthermore, carbon emissions associated with soybean production was estimated by modeling the effect of a potential carbon tax as well as the potential benefit of carbon offset payments resulting from carbon sequestration. The …
