Palmer Amaranth (Amaranthus palmeri) Impacts on Yield, Harvesting, and Ginning in Dryland Cotton (Gossypium hirsutum)

Abstract

The impact of Palmer amaranth on mechanical harvesting, ginning, and fiber quality in dryland cotton was documented. Only the highest Palmer amaranth density (3,260 weeds/ha) reduced lint and seed yields. However, all weed densities increased harvesting time 2- to 3.5-fold. Two factors increased the time required for stripper harvesting: slower ground speeds due to large weeds and work stoppages that required hand removal of weed stems lodged in the harvester. Ninety-eight percent of the weedy plant material was discarded in the field by the harvester, and the remaining 2% was successfully removed in ginning and lint-cleaning processes. Weed infestations did not result in any differences in moisture content of seed cotton, ginning time, fiber quality, or the percentage of cleaned lint.
