Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2007 And Revised Estimates For 2006, Nathan Kemper, Jennie Popp, Wayne Miller Dec 2009

Economic Contribution Of The Agricultural Sector To The Arkansas Economy In 2007 And Revised Estimates For 2006, Nathan Kemper, Jennie Popp, Wayne Miller

Research Reports and Research Bulletins

This report is the fourth in a series of reports examining agriculture’s economic contribution on the Arkansas economy. Utilizing data from the United States Bureau of Economic Analysis, USDA Economics Research Service, USDA National Agricultural Statistics Service, and Minnesota IMPLAN Group, Inc., the economic contribution of agriculture on the Arkansas economy was estimated for the most recent year available, 2007. Gross Domestic Product (GDP) by State information for Arkansas was compared with those of other states in the southeast U.S. to give a measure of the relative importance of agriculture in Arkansas. The total economic contribution of agriculture (direct, indirect, …

Wayne E. Sabbe Arkansas Soil Fertility Studies 2008, Nathan A. Slaton

Arkansas Agricultural Experiment Station Research Series

Rapid technological changes in crop management and production require that the research efforts also be presented in an expeditious manner. The contributions of soil fertility and fertilizers are major production factors in all Arkansas crops. The studies described within will allow producers to compare their practices with the university’s research efforts.

Good Agricultural And Handling Practices For Grapes And Other Fresh Produce, Pamela L. Brady, Justin R. Morris Jan 2009

Good Agricultural And Handling Practices For Grapes And Other Fresh Produce, Pamela L. Brady, Justin R. Morris

Research Reports and Research Bulletins

In recent years consumption of fresh fruits and vegetables has increased dramatically. This trend has increased the amount of produce being purchased at farmer’s markets, road-side stands, and neighborhood markets since consumers say they feel that the direct contact with growers at these markets makes them better able to assess the quality and safety of the produce. This buying trend has opened new markets to small- and medium-sized farms, which sell at these local outlets.


Analysis Of The Accase Mutation Profile Of Italian Ryegrass (Lolium Perenne Ssp. Multiflorum) Accessions Resistant To Accase Inhibitors, Thomas Stark Jan 2009

Analysis Of The Accase Mutation Profile Of Italian Ryegrass (Lolium Perenne Ssp. Multiflorum) Accessions Resistant To Accase Inhibitors, Thomas Stark

Inquiry: The University of Arkansas Undergraduate Research Journal

Lolium perenne ssp. multiflorum (Italian ryegrass) resistant to ACCase inhibiting herbicides has been reported in many wheat producing counties across Arkansas. Resistance is believed to be the result of point mutations creating amino acid substitutions in the CT domain of the plastidic ACCase gene. This study explores the occurrence of mutations in the ACCase gene of ryegrass populations. Plant material was collected and DNA was extracted from 10 Arkansas ryegrass populations. Six of the populations were known to be resistant to the ACCase inhibitor diclofop-methyl, while the remaining four populations were known to be susceptible to diclofop-methyl. Two highly conserved …


History Of Development And Characterization Of The U.S. Blackberry Market, Thais F. Carvalho, John R. Clark, Michael R. Thomsen Jan 2009

History Of Development And Characterization Of The U.S. Blackberry Market, Thais F. Carvalho, John R. Clark, Michael R. Thomsen

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

The fresh blackberry market within the United States has expanded significantly in the past 10 years based on the development of new cultivars with improved firmness and longer shelf life, permitting their shipment over long distances. Currently, blackberries maintain a nearly continuous presence on the shelves of grocery stores across the U.S., which was uncommon a decade ago. Increased consumption of blackberries is due to increased consumer desire for improved nutrition and diet along with expanded availability. Worldwide, producers have increased production with a 45% increase in area planted from 1995 to 2005. Further expansion has occurred since then. This …


Characterizing The Variability Of Physical And Chemical Properties Across The Soil Individuals Mapped As Amy Silt Loam Soils In Southeastern Arkansas, B. Bhandari, Robert L. Ficklin Jan 2009

Characterizing The Variability Of Physical And Chemical Properties Across The Soil Individuals Mapped As Amy Silt Loam Soils In Southeastern Arkansas, B. Bhandari, Robert L. Ficklin

Journal of the Arkansas Academy of Science

Knowledge of physical and chemical properties of soil is relevant for landowners, researchers, and foresters, so that appropriate crop species and management practices to maximize site productivity can be selected. In addition to issues of plant productivity, the need for assessing soil properties has been expanded due to public interest in determining the consequences of management practices on soil quality relative to sustainability of crop ecosystem functions. The USDA-Natural Resources Conservation Service (NRCS) delineated soil mapping units to provide information about physical and chemical properties of soil in each soil series. However, soil mapping units do not provide details about …

Establishing A Rapid And Effective Method For Screening Salt Tolerance In Soybean, Mioko Tamura, Pengyin Chen Jan 2009

Establishing A Rapid And Effective Method For Screening Salt Tolerance In Soybean, Mioko Tamura, Pengyin Chen

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

Chlorine (Cl) toxicity has been recognized as a constraint for soybean production. Although the use of a Cl-tolerant crop easily solves the problem, current screening methodologies for Cl tolerance are often ineffective because of inadequate means of detecting and measuring plant response to salinity. In order to facilitate the evaluation process and selection of Cl-tolerant genotypes, a study was conducted to develop a rapid and effective method for screening Cl tolerance in soybean. Seeds of five soybean cultivars, each representing either the includer or excluder genotype to salt stress, were grown in a greenhouse in two different growing media (potting …


Processing And Storage Effects On The Polyphenolic Content And Antioxidant Capacity Of Conventional And Sugar-Free Blueberry Jams, Chelsea Castrodale, Luke Howard, Cindi Brownmiller Jan 2009

Processing And Storage Effects On The Polyphenolic Content And Antioxidant Capacity Of Conventional And Sugar-Free Blueberry Jams, Chelsea Castrodale, Luke Howard, Cindi Brownmiller

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

Fresh blueberries have received much attention due to their positive role in human health and disease prevention. The abundance of polyphenolics, namely anthocyanins and procyanidins, is thought to play an important role in health promotion. Due to seasonal availability and limited shelf-life, blueberries are commonly preserved and consumed in various thermally processed forms (jams, juices, canned whole fruit, and purées). Both conventional high sugar and sugar-free blueberry jams are available on the market, but no information is available on how different formulations, processing conditions, and storage of processed jams affect the retention of polyphenolics and antioxidant capacity found in fresh …


Developing Enterprise Budgets For Sustainable School Gardens: Service Learning In A Global Context, Ashley D. Jones, Jennie S. Popp Jan 2009

Developing Enterprise Budgets For Sustainable School Gardens: Service Learning In A Global Context, Ashley D. Jones, Jennie S. Popp

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

Service learning programs are becoming a part of curricula in universities throughout the United States. The University of Arkansas, Fayetteville, (UAF) established a service learning program that targeted the educational, health, social, and agricultural needs of a community. The focus of this research aimed to provide students, faculty, community members, school officials, and students with a template for crop budgets. These crop budgets are used to evaluate the costs and returns of producing multiple crops at a school. Crops produced in a sustainable garden must meet three criteria: 1) have minimal negative environmental impact, 2) provide just-in-time production of quality …
