Summaries Of Arkansas Cotton Research 2002, Derrick M. Oosterhuis
Arkansas Agricultural Experiment Station Research Series
The average yield in Arkansas in 2002 was 871 lb lint/acre from 920,000 harvested acres (960,000 planted) for a total of 1.67 million bales at a value of$336.5 million. This yield was second only to the record 877 lb lint/acre achieved in 1994. Last year's crop yield, and the five-year average, on a per acre basis are exceeded in the U.S. Cotton Belt only by California and Arizona. Cotton yields in Arkansas increased steadily during the eighties, but in the last decade yields have leveled off. Furthermore, the last five years have had extreme year-to-year variability in yields, which is …

Arkansas Agriculture Situation And Outlook 2003, Bruce L. Ahrendsen, Eric J. Wailes, Bruce L. Dixon, Michael Popp, Pat Manning, Tony E. Windham
Arkansas Agriculture Situation And Outlook 2003, Bruce L. Ahrendsen, Eric J. Wailes, Bruce L. Dixon, Michael Popp, Pat Manning, Tony E. Windham
Arkansas Agricultural Experiment Station Research Series
The purpose of this research series is to highlight the situation of Arkansas farmers and to offer an outlook for 2003. The research emphasizes the production, price, income, policy, financial, farmland value, and interest rate outlook for Arkansas farmers and considers the impact of the macro economy on agriculture. In addition, the advantages and disadvantages of biodiesel as an alternative to petroleum diesel are discussed.

B.R. Wells Rice Research Studies 2002, R. J. Norman, J.-F. Meullenet
Arkansas Agricultural Experiment Station Research Series
Arkansas is the leading rice producing state in the U .S .. representing almost 46% of the total U .S. production and almost 47% of the total acres planted to rice . Rice cultural practices vary across the state and across the U.S. However, due to changing political, environmental, and economic times, the practices arc dynamic. This survey was initiated in 2002 to monitor how the changing times reflect the changes in the way Arkansas rice producers approach their livelihood. The survey was conducted by polling county Extension agents in each of the counties in Arkansas that produce rice. Questions …
Arkansas Small-Grain Cultivar Performance Tests 2002-2003, J. T. Kelly, C. E. Parsons, R. K. Bacon
Arkansas Small-Grain Cultivar Performance Tests 2002-2003, J. T. Kelly, C. E. Parsons, R. K. Bacon
Arkansas Agricultural Experiment Station Research Series
Small-grain cultivar performance tests are conducted each year in Arkansas by the Arkansas Agricultural Experiment Station, Department of Crop, Soil and Environmental Sciences. The tests provide information to companies developing cultivars and/or marketing seed within the state and aid the Arkansas Cooperative Extension Service in formulating cultivar recommendations for smallgrain producers.
Arkansas Cotton Variety Test 2002, E. M. Bourland, J. T. Johnson, S. B. Jackson, M. W. Duren, J. M. Hornbeck, F. E. Groves, W. C. Robertson
Arkansas Cotton Variety Test 2002, E. M. Bourland, J. T. Johnson, S. B. Jackson, M. W. Duren, J. M. Hornbeck, F. E. Groves, W. C. Robertson
Arkansas Agricultural Experiment Station Research Series
The primary aim of the Arkansas Cotton Variety Test is to provide unbiased data regarding the agronomic performance of cotton varieties and advanced breeding lines in the major cotton-growing areas of Arkansas. This information helps seed dealers establish marketing strategies and assists producers in choosing varieties to plant. In this way, the annual test facilitates the inclusion of new, improved genetic material into Arkansas cotton production. Variety adaptation is determined by evaluation of the varieties and lines at four University of Arkansas research stations located near Keiser, Clarkedale, Marianna, and Rohwer. Tests are duplicated in irrigated and non-irrigated culture at …

Chitosanase May Enhance Anti-Fungal Defense Responses In Transgenic Tobacco, Bill L. Hendrix, James Mcd. Stewart
Chitosanase May Enhance Anti-Fungal Defense Responses In Transgenic Tobacco, Bill L. Hendrix, James Mcd. Stewart
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Chitosanase is an enzyme, similar to chitinase, capable of hydrolyzing the β-1,4-linkages between N-acetyl-D-glucosamine and D-glucosamine residues in partially acetylated chitosan polymers found in fungal cell walls. When attacked by pathogenic fungi, many plants exploit this hydrolytic action as a component of a larger post-attack defense response, but these enzymes may also play a role in the initial plant-pathogen interaction via the generation of elicitors resulting from the hydrolysis of fungal cell walls. To gain insight into these mechanisms, a Paenbacillus chitosanase was cloned, sequenced, and modified for plant expression. The modified gene was delivered to tobacco (Nicotiana tabacum L. …

Effect Of Triticum Turgidum Cytoplasm On Test Weight Of Soft Red Winter Wheat, Juan Mayta, Robert Bacon, John Kelly, Edward Gbur
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The effect of Triticum turgidum cytoplasm on soft red winter wheat (T. aestivum) was studied relative to test weight (bushel weight) and agronomic traits such as heading date, resistance to leaf rust, and plant color. The cytoplasmic effects were studied in three genetic backgrounds by crossing the cultivars Jackson, Pioneer 2684, and Wakefield with a plant introduction PI590277 that carried T. turgidum cytoplasm. Twelve alloplasmic and euplasmic populations were developed through a backcrossing procedure. The study used a micro test weight procedure to compare F4 lines within the populations for test weight. The data for other agronomic traits were taken …

Focus Group Survey Results: Typical Arkansas Crop Producer Production And Marketing Practices, Jason Hill, Michael Popp, Patrick Manning
Focus Group Survey Results: Typical Arkansas Crop Producer Production And Marketing Practices, Jason Hill, Michael Popp, Patrick Manning
Research Reports and Research Bulletins
This report contains information from a 2001 focus group survey of production practices and marketing decisions of ‘typical’ representative Arkansas farms from selected counties in eastern Arkansas. While the National Agricultural Statistical Service (NASS) publishes similar information through the Arkansas Agricultural Statistics Service, reporting of these statistics is often not differentiated across crops or specific farm type. Therefore, one of the major objectives of this survey was to ascertain production practices for specific crops and farm types typical of row crop farms in eastern Arkansas. Responses were categorized into production regions dominated by either rice or cotton production. The results …

Response Of Blackberry Cultivars To Nematode Transmission Of Tobacco Ringspot Virus, Alisha Sanny
Response Of Blackberry Cultivars To Nematode Transmission Of Tobacco Ringspot Virus, Alisha Sanny
Inquiry: The University of Arkansas Undergraduate Research Journal
A study was conducted on eight cultivars of blackberry ('Apache', 'Arapaho', 'Chester', 'Chickasaw', 'Kiowa', 'Navaho', 'Shawnee', and 'Triple Crown'), of which four plants of each were previously determined in the fall of 2001 to have root, but not leaf, infection with Tobacco ringspot virus (TRSV). The objective of our study was to determine virus effects on plant vigor, and the spread of virus infection in the plants. Eight plants of each cultivar, four infected and four free of infection, were grown in pots on a gravel pad for the 2002 growing season, and samples of primocane and floricane leaves were …
