NEREC Research Project List and Summaries Resident Research and Extension Programs:
The primary goal 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 companies establish marketing strategies and assists producers in choosing varieties to plant. These annual evaluations will then facilitate the inclusion of new, improved genetic material in Arkansas cotton production. Adaptation of varieties is determined by evaluating the lines at four University of Arkansas research sites: Northeast Research and Extension Center at Keiser, Judd Hill Foundation Cooperative Research Station near Trumann, the Lon Mann Cotton Research Station at Marianna, and the Southeast Branch Station at Rohwer. Data are reported at www.ArkansasVarietyTesting.org and in hard copy. The data include yield, lint percentage, plant height, open bolls, yield component variables, fiber properties, Verticillium wilt, leaf pubescence, and bract parameters. Entries are also evaluated for response to tarnished plant bug in a separate test at Keiser. All handling of seed, data and samples are done at Keiser.
The University of Arkansas Cotton Breeding Program attempts to develop cotton genotypes that are improved with respect to yield, host plant resistance, fiber quality, and adaptation to Arkansas environments. Such genotypes would be expected to provide higher, more consistent yields with fewer inputs. To maintain a strong breeding program, continued research is needed to develop techniques, which will identify genotypes with favorable genes, combine those genes into adapted lines, then select and test derived lines. The Program is headquartered at Keiser, where laboratory (ginning, seed and fiber sampling, delinting, seed quality evaluation, seed storage, and seed packaging), greenhouse (evaluation and screens for disease resistance), early-generation population development (crossing, generation advance), field tests (progeny and strain evaluation) and seed increases are conducted. Addition evaluation of progeny and strains are routinely conducted at Judd Hill, Marianna (Lon Mann Cotton Research Station) and Rohwer (Southeast Branch Station). Advanced strains are also evaluated in various regional tests and are released to all public and private breeders as appropriate. Dr. Robert Hogan (Agricultural Economics) The agricultural economics program at the Northeast Research and Extension Center is comprised of three parts: 1) farm management and production economics, 2) agricultural markets and marketing, and 3) public policy analysis. The program examines issues of concern to Delta producers concerning the production and marketing of cotton, soybean, rice, wheat, feed grains, beef cattle, irrigation management, and capital investments in equipment and machinery. Specific objectives include:
Dr. Daniel Stephenson (Cropping Systems Agronomy and Weed Science)
The University of Arkansas Cropping Systems Research Program attempts to improve current crop production systems and to investigate the feasibility of new and innovative crop production practices. The program is headquartered at the Keiser location with additional testing sites at Marianna, Judd Hill, and cooperator locations throughout Northeast Arkansas. Primary objectives include research into corn, cotton, grain sorghum, rice, soybean, wheat, and potential alternative crop production systems and to evaluate systems to reduce management inputs, stabilize yields, and maximize economic returns. Dr. Glenn Studebaker (Entomology)
The University of Arkansas Pest Management Program focuses on improving management of insect pests through studies conducted at Keiser, Marianna, Judd Hill and various producer farms in NE Arkansas. Studies focus on evaluating the efficacy of experimental as well as currently labeled insecticides. The efficacy and economic returns of gmo's such as Bt crops are also evaluated. Results are used to enhance University recommendations.
The hub of the commercial beekeeping industry in Arkansas is located in the NE delta. Issues concerning pests of honey bees such as the varroa mite and small hive beetle are addressed through section 18's for products that are effective in managing these pests.
