Arkansas is the leading rice producer in the United States. The state represents 49.0% of total U.S. rice production and 49.6% of the total acres planted to rice in 2023. Rice cultural practices vary across the state and across the U.S. However, these practices are also dynamic and continue to evolve in response to changing political, environmental, and economic times. This survey was initiated in 2002 to monitor and record 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 …
Summaries Of Arkansas Cotton Research 2023, Fred Bourland
Summaries Of Arkansas Cotton Research 2023, Fred Bourland
Arkansas Agricultural Experiment Station Research Series
With current production costs and cotton prices, either record or near-record yields are needed for profitable cotton production in Arkansas. As usual, price volatility in 2023 added another level of difficulty in the quest for being profitable. Cotton futures traded between 80 and 90 cents per pound in 2023, with brief times below 80 cents and above 90 cents. In April, cotton futures dropped below 80 cents per pound, the lowest level in almost four months. This was due to an increase in certificated stocks, declining demand, and a growing world carryover. The average cotton price received by U.S. growers …
Near-Surface Soil Property Change Over Time In Two Native Tallgrass Prairies In The Arkansas River Valley, Katie Jansson
Near-Surface Soil Property Change Over Time In Two Native Tallgrass Prairies In The Arkansas River Valley, Katie Jansson
Crop, Soil and Environmental Sciences Undergraduate Honors Theses
One climate-change mitigation pathway is soil carbon (C) sequestration, which removes carbon dioxide from the atmosphere and stores C in various forms in the soil. Native prairie soils have long been known for their soil C sequestration abilities, but the full extent of their sequestration capacity is not completely understood. This study evaluated the effect of soil depth and soil map unit/prairie combination on changes in various soil properties over time from 2018 to 2022 in the top 20 cm of two native tallgrass prairie soils in the Arkansas River Valley in west-central Arkansas. Soil samples were collected from the …
Evaluation Of Late Season Potassium Applications To Arkansas Soybean, Carrie Ortel
Evaluation Of Late Season Potassium Applications To Arkansas Soybean, Carrie Ortel
Graduate Theses and Dissertations
Potassium (K) deficiency is one of the most important yield limiting factors in Arkansas soybean (Glycine max (L.) Merr.) production, although there are recently improved diagnostic and management opportunities available. However, several questions regarding the successful implementation of in-season K management in soybean production remain. Therefore, the research objectives were to (a) delineate the relationship between drought stress and K deficiency on soybean vigor, (b) identify the spatial dependencies of leaf-K concentrations at the production scale, (c) develop a leaf sampling protocol, (d) calibrate the fertilizer-K rate needed to correct varying levels of K deficiency at 15, 30, and 45 …

he primary goal of the Arkansas Cotton Variety Tests 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 five University of Arkansas System Division of Agriculture research sites (Manila, Keiser, Judd Hill, Marianna, and Rohwer). The 2023 tests at Keiser were adversely affected …

Wayne E. Sabbe Arkansas Soil Fertility Studies 2023, Nathan A. Slaton
Arkansas Agricultural Experiment Station Research Series
Rapid technological changes in crop management and production require that the research efforts 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. Additionally, soil-test data and fertilizer sales are presented to allow comparisons among years, crops, and other areas within Arkansas.
