Field experiments were conducted in 1999 and 2000 to evaluate and adapt the Herbicide Application Decision Support System (HADSS®) program for Texas Southern High Plains cotton production. Weed management systems (in glyphosate-resistant, bromoxynil-resistant, and nontransgenic cotton varieties) included trifluralin preplant incorporated (PPI) followed by (fb) HADSS postemergence-topical (POST) recommendations (PPI fb POST HADSS), HADSS recommendations alone (POST HADSS), and Texas Agricultural Experiment Station (TAES) recommendations for the Texas Southern High Plains. In both years, effective season-long weed control was achieved with all weed management systems in the glyphosate-resistant variety, but only the PPI fb POST HADSS and TAES weed management systems controlled Palmer amaranth and devil's-claw in the bromoxynil-resistant and nontransgenic varieties, compared with POST HADSS alone. No differences in cotton lint yield or net returns over weed control costs were observed with weed management systems across variety in 1999; however, in general, the glyphosate-resistant and nontransgenic varieties produced higher yields and net returns than the bromoxynil-resistant variety. In 2000, plots from the TAES weed management system produced higher lint yields than the plots of PPI fb POST HADSS recommendations in the glyphosate- and bromoxynil-resistant varieties, but plots of all management systems yielded similarly in the nontransgenic variety. In 2000, plots from the TAES system produced the highest net returns in the glyphosate- and bromoxynil-resistant varieties. In the nontransgenic variety, the PPI fb POST HADSS and TAES weed management systems produced higher net returns over weed control costs than the POST HADSS system.

The Impact

The impact of the harvesting method, as well as the ginning method (saw or high-speed roller ginning), on textile quality was studied over three years of cotton production in the Southern High Plains. The Southern High Plains region is the largest cotton production area of the USA. The Southern High Plains and the Texas Gulf Coast are the only areas of the USA where brush-roll stripper harvesting is common, alongside traditional spindle picker machine harvesting. Different harvesting methods lead to differences in micronaire, maturity, length distribution, color and non-lint content within the bale. Ginning differences were primarily found to be length and length distribution related. Lint was processed into rotor-spun, carded ring-spun and combed ring-spun medium count yarns to determine the impacts of harvesting and ginning methods on textile product quality. Rotor spinning produced comparable quality yarns regardless of harvest or ginning method, while carded ring-spun yarns showed statistical differences in quality, with spindle-picked cottons having greater uniformity and higher tenacity. Combing was able to eliminate any functional differences in quality due to the pre-mill handling of the cottons at the expense of increased noil levels for stripper-harvested cottons. There were no differences in ends-down during ring spinning, regardless of harvest and ginning method, although cottons produced with high-speed roller ginning were able to be spun at higher spindle speeds, which equates to higher production speeds.

System A

Field trials were established in 2005 and continued in 2006 to evaluate a conventional broadcast herbicide sprayer compared to a variable spray (sensor-activated) weed-sensing sprayer (WSS). The computer-based Herbicide Application Decision Support System (WebHADSS™) was used to determine a portion of the herbicides applied (based on herbicide efficacy and economics). Weed control, herbicide usage, crop yield, and net returns were compared across treatments. The broadcast applications were usually the most effective at controlling weeds. A PPI herbicide did not always improve weed control compared to treatments in which no PPI herbicide was applied. Variable treatments used less herbicide than the broadcast system in both years. Cotton lint yields in broadcast applications were similar to the weed-free check in both years of the study. Variable treatments often provided equivalent net returns (gross yield revenue less weed control cost) to the broadcast treatments. Although herbicide savings were observed in the variable treatments when compared to a broadcast system, a reduction in weed control was observed, indicating the need for future improvements of this system. A site-specific weed management program used in conjunction with WebHADSS™ may have potential in cotton production systems in the Texas Southern High Plains where weed densities are low.
