Origin, Rise And Development Of American Upland Cotton And Their Status At Present. Second Edition, Ed. By F.M. Bourland, J. O. Ware
Research Reports and Research Bulletins
American Upland cotton (Gossypium hirsutum) is a Dixie product. Although the stocks of the species were brought from elsewhere, new types (through series of adaptational changes) formed this distinctive group—the final characteristics of which are a product of the Cotton Belt of the United States. These biological processes were considerably aided by man and the steps of development possibly were about as follows: (a) natural selection took place in the earlier introductions, (b) seed were saved from the more choice stocks, (c) series of subsequent introductions were obtained from the better sources, (d) these were acclimatized and the superior ones …
Short-Term Soil Organic Matter And Carbon Responses To Contrasting Grazing Intensities In Integrated Crop-Livestock Systems, Erick R. Da Silva Santos, Jose C. B. Dubeux, B. G. C. Homem, Cheryl L. Mackowiak, Lynn E. Sollenberger, D. Wright
Short-Term Soil Organic Matter And Carbon Responses To Contrasting Grazing Intensities In Integrated Crop-Livestock Systems, Erick R. Da Silva Santos, Jose C. B. Dubeux, B. G. C. Homem, Cheryl L. Mackowiak, Lynn E. Sollenberger, D. Wright
IGC Proceedings (1993-2023)
Combining integrated crop-livestock systems under no-till management may improve soil organic matter (SOM) build up and improve soil C sequestration. Grazing cover crops appears as a possibility to combine crops and livestock in a farm system. Further SOM and soil C increase can be achieved by adding perennial grasses into crop rotations. However, the effect of grazing intensity in such systems are not fully understood. This 2-yr study investigated short-term effects of cropping system [winter cover crops-summer cotton (Gossypium hirsutum L.) and winter cover crops-summer bahiagrass (Paspalum notatum Flüggé) rotations], grazing intensity (no grazing, heavy, moderate, and light …

Arkansas Agricultural Experiment Station Research Series
The current economic environment continues to drive the need to produce record or near-record yields to be profitable. Price volatility in 2022 added another level of difficulty in the quest for being profitable. The cotton market saw significant movement after reaching a $1.5802 per pound high in May 2022, cotton prices corrected and more than halved in value at the October 2022 low, and then consolidated around the 80 cents per pound level in December 2022 (Cotton is Consolidating). Great uncertainties still exist for the upcoming season, most of which are outside of our control. These include, but are not …
Survey And Prevalence Of Palmer Amaranth Herbicide Resistance In South Carolina, Mitchell Williams
Survey And Prevalence Of Palmer Amaranth Herbicide Resistance In South Carolina, Mitchell Williams
All Theses
Palmer amaranth is a troublesome weed for growers to control, not only due to its aggressive growth characteristics that limit row-crop production, but because of its resistance to different herbicide modes of action. The first case of herbicide resistance in Palmer amaranth was detected in 1989 and has since grown to nine different herbicide classes throughout the United States. New herbicide modes of action have not been developed since the 1980s, so proper stewardship of the remaining modes of action is important for effective control of Palmer amaranth. Increased herbicide resistance from states bordering South Carolina have been reported; therefore, …
Influence Of Potassium Fertilizer Application Timing On Cotton Production As Related To Soil Potassium On U.S. Coastal Plain Soils, Shruthy Suresh Kumar
Influence Of Potassium Fertilizer Application Timing On Cotton Production As Related To Soil Potassium On U.S. Coastal Plain Soils, Shruthy Suresh Kumar
All Theses
Understanding soil K dynamics is highly significant in cotton production owing to its prominent role in cotton fiber quality. About 31 % of cotton production in the U.S. is concentrated in SE states, with coastal plain soils having low innate K availability. Crop fertilizer-K recommendations are primarily made worldwide and across the U.S. using pre-plant STK concentrations. A literature review on cotton K studies suggests that fertilizer-K recommendations based on pre-plant STK concentrations alone need fine-tuning to meet the increasing K demands in modern cultivars, variations in crop K requirement patterns, and varied soil K supplying capacity. Studies have been …
Precision Management Of Inputs In Cotton And Soybean Production In South Carolina, Kyle Smith
Precision Management Of Inputs In Cotton And Soybean Production In South Carolina, Kyle Smith
All Theses
The adoption of precision agriculture technologies and developing specific product use recommendations in cotton and soybean production could help farmers reduce input costs and optimize overall farm profitability. The objectives of this research were to evaluate whether or not the use of variable rate seeding in cotton could increase profitability and to determine the rainfast interval of commonly used insecticides in cotton and soybean production. The first trial, variable rate seeding in cotton, was implemented at the Edisto Research and Education Center near Blackville, SC across five years to evaluate variable rate seeding in cotton. Results from trials in South …

Arkansas Agricultural Experiment Station Research Series
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 five University of Arkansas System Division of Agriculture research sites (Manila, Keiser, Judd Hill, Marianna, and Rohwer). The 2022 tests at Rohwer were adversely affected …
