"Bound Together . . . By Blood And Soul": Donald Davidson's Strategic Retreat Into The Myth Of Life In The Old South, Carol Pigg

Masters Theses & Specialist Projects

Donald Davidson has often been called stubborn because of his refusal to let go of the Southern past and in his insistence that his writings be based on and in the regional concerns that he saw as fundamental to all Southern literature. In many ways, Davidson's loyalty to the Agrarian and Fugitive causes, which are best defined in these groups interest in keeping the South's history alive and maintaining an agrarian lifestyle, is his greatest contribution to the Southern and American literary canon. Despite this fact, though, Davidson is now, as he was during his lifetime, ignored because of the …

Herbicide Evaluation In Arkansas Cotton, 1999, Marilyn Mcclelland, Jim Barrentine, Ken Smith, Nilda Burgos

Arkansas Agricultural Experiment Station Research Series

Herbicidal weed control is economically important for production of cotton. Field experiments are conducted annually in Arkansas to evaluate the activity of developmental and commercial herbicides for selective control of weeds in cotton. These experiments serve both industry and Arkansas agriculture by providing information on the selectivity of herbicides still in the developmental stage and by comparing the activity of these new herbicides with that of recommended herbicides.

Two Large-Insert Soybean Genomic Libraries Constructed In A Binary Vector: Applications In Chromosome Walking And Genome Wide Physical Mapping, K. Meksem, K. Zobrist, E. Ruben, D. L. Hyten, T. Quanzhou, H-B. Zhang, D. A. Lightfoot

Department of Agronomy and Horticulture: Faculty Publications

Large DNA insert libraries in binary T-DNA vectors can assist in the isolation of the gene(s) under-lying a quantitative trait locus (QTL). Binary vectors facilitate the transfer of large-insert DNA fragments containing a QTL from E. coli to Agrobacterium sp. and then to plants. We constructed two soybean large-insert libraries from cv. Forrest in the pCLD04541 (V41) binary vector after partial digestion of genomic high-molecular-weight DNA with BamHI or HindIII. The libraries contain 76,800 clones with an average insert size of 125 kb, and therefore represent 9.5-fold haploid genome equivalents. Colony hybridization using a chloroplast-specific probe infers that …

Reconditioning Corn And Soybeans To Optimal Processing Moisture Contents, Michael D. Montross, Dirk E. Maier

Biosystems and Agricultural Engineering Faculty Publications

Experimental trials were carried out to evaluate the technical feasibility of reconditioning overly dry corn and soybeans to optimal market and processing moisture contents. Data obtained from experimental trials were used to validate an aeration simulation model. This model was used to evaluate the feasibility of reconditioning soybeans and corn. Reconditioning of grain was feasible at low airflow rates (0.11 m³ min^–1 t^–1) over a six-month period when an automatic aeration controller was used. Using downflow aeration and monthly unloading of the bin allowed for the greatest net economic gain. Predicted reconditioning in Des Moines, Iowa, …

Soybean Marketing Methods And Characteristics Of Arkansas Grain Handlers, Patricia A. Sauer, Nathan B. Smith, Andrew M. Mckenzie

Research Reports and Research Bulletins

Arkansas producers should acquaint themselves with all marketing methods available to them. Of particular importance is the pervasiveness of price risk within the current economic climate. This bulletin provides insights into the current structure of the grain marketing industry, soybean handler characteristics, and the availability and use of marketing alternatives in Arkansas. Arkansas soybean handlers were surveyed in 1998 to determine the marketing practices of both handlers and producers for the 1996 crop year. Particular emphasis was placed on the types of contracting methods offered by these handlers. Both facility size and corporate structure were found to play a significant …

Identifying Areas Of Agricultural Significance, Ian Kininmonth

Agriculture reports

The protection of productive agricultural land and the avoidance of land use conflicts in rural areas are important objectives of the Western Australian Government. They are reflected in the State Planning Strategy, Agriculture Western Australia’s strategic plan, ‘Focus on the Future’ and draft Statement of Planning Policy (SPP) No. 11 – Agricultural and Rural Land Use Planning Policy. However, agricultural land is required for a variety of purposes and so it is important that agriculture is able to identify those areas which are irreplaceable in terms of existing and future production and those areas which may be used for other …

Simulated Performance Of Conventional High-Temperature Drying, Dryeration, And Combination Drying Of Shelled Corn With Automatic Conditioning, Michael D. Montross, Dirk E. Maier

Biosystems and Agricultural Engineering Faculty Publications

Combination drying, based on computer simulation, was evaluated as an alternative drying technique to traditional high-temperature drying and dryeration. Simulation models of high-temperature crossflow drying and in-bin drying and conditioning were used to evaluate the performance of conventional crossflow drying and full-heat crossflow drying followed by dryeration or natural-air drying for Indianapolis, Indiana, and Des Moines, Iowa. Energy costs from propane, electricity, moisture shrink below the market moisture content, and dry matter loss were estimated to find the total average drying cost over 29 years. Dryeration and combination drying reduced the total drying cost by approximately 10% compared to conventional …

Arkansas Cotton Variety Test 1999, Fred M. Bourland, N. R. Benson, J. M. Hornbeck, C. D. Capps Jr.

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 in the major cotton growing areas in 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. The 1999 test had 67 entries (including 25 transgenic genotypes and 35 first-year entries), which were evaluated at sixsites in eastern Arkansas. The presence of four transgenic and five first-year entries among the top 10 yielding entries …

Field Evaluation Of Herbicides On Small Fruit, Vegetable, And Ornamental Crops, 1999, Ron E. Talbert, Lance A. Schmidt, Mike L. Lovelance, Eric F. Scherder

Arkansas Agricultural Experiment Station Research Series

Growers generally use herbicides to efficiently produce high-quality fruit and vegetables for processing or fresh market sales. Because of the smaller acreage of these crops compared with major field crops, fewer herbicides are registered for use in fruit and vegetable crops than for field crops. Each year, new herbicides are evaluated under Arkansas growing conditions with the objective of improving the herbicide technology for the grower, processor, and ultimately the consumer. This report includes studies on the control of many of the more serious weed problems in important crops of this region, including snapbeans, spinach and other greens, southernpeas, tomatoes, …

Pb1648-Considering An Agritainment Enterprise In Tennessee, The University Of Tennessee Agricultural Extension Service

Marketing, Finances and Value-Added Agriculture

Agritainment (agritourism and entertainment farming enterprises) has an extensive history in the United States. Farm-related recreation and tourism can be traced back to the late 1800s, when families visited farming relatives in an attempt to escape from the city’s summer heat. Visiting the country became even more popular with the widespread use of the automobile in the 1920s. Rural recreation gained interest again in the 1930s and 1940s by folks seeking an escape from the stresses of the Great Depression and World War II. These demands for rural recreation led to widespread interest in horseback riding, farm petting zoos and …

Efficacy, Phytotoxicity, And Cover Crop Response Of Herbicide Combinations In Dark Fire Cured Tobacco, Tracy Kelley

Masters Theses & Specialist Projects

Field studies were established during the summer of 1999 at the Agricultural Research and Education Complex of Western Kentucky University to evaluate efficacy, phytotoxicity, and cover crop response of herbicide combinations in dark fire cured tobacco. A randomized complete block design was used with nine treatments replicated three times. Hydroponic tobacco transplants (c.v. 'TND950') were established on May 20,1999 in a conventionally tilled system on a Pembroke silt loam (Mollic Palleudalf) with a pH of 5.8 and an organic matter content of 1.2%. The transplants were established at a population of approximately 10,278 plants/ha. Herbicide treatments were applied on May …

Three tests were conducted over a 2-year period in lowland irrigated rice fields on the WARDA Research Station at Bouaké, Côte d’Ivoire, to obtain information on the strepsipteran parasitism of white leafhoppers, Cofana spectra and C. unimaculata. Rice cultivars were sampled with a sweep net to collect leafhoppers for determination of the relative abundance of the two leafhopper species and the effect of rice cultivar and rice crop age on the leafhopper populations and percent strepsipteran parasitism. Dissections of the leafhoppers were made to determine the relative number of the various parasitic stages in the leafhoppers. Cofana unimaculata populations …

Root Growth And Development Of Float Tobacco Transplants Before And After Transplanting, L. V. Caruso, Robert C. Pearce, Lowell P. Bush

Agronomy Notes

In the production of float tobacco transplants, the seedling produces at least two different kinds of roots. The “media” roots are those that grow in the soilless medium within the float tray cell. They have a normal branched appearance similar to roots produced on soil-bed grown transplants. The “water” roots grow through the soilless medium in tray cells and into the nutrient solution below the float tray. They tend to be very fragile and less branched than roots growing in the soilless medium. In removal of seedlings from tray cells during transplanting, “water” roots are usually badly damaged or destroyed, …

Escherichia Coli Pathogen O157:H7 Does Not Survive Longer In Soil Than A Nonpathogenic Fecal Coliform, D. N. Mubiru, Mark S. Coyne, John H. Grove

Agronomy Notes

Survival rates for individual types of fecal organisms are quite different. Although some pathogens may persist as long as 5 years in soil, most fecal pathogens from human and animal waste usually die very quickly. Two to three months is sufficient in most cases to reduce pathogens to negligible numbers once they have been excreted or land-applied in animal wastes.

It is expensive and time- consuming to test for individual pathogens. Consequently, nonpathogenic fecal indicator bacteria, which are easily and inexpensively detected, are often used to study pathogen survival in soil and water. Current methods for rapidly detecting fecal indicator …
