Abstract
Weather, varietal, harvesting, and ginning effects on seed-coat fragment count and weight in ginned lint cotton were evaluated in a 2-year study in the Mississippi Delta. In this study, harvest and lint cleaner treatments had almost no effect on fragment count, while year and variety had strong influences. Based on 3 grams of lint, the fragment count averaged 51 and the total fragment weight averaged 46 mg. Weight was reduced from 83 to 24 mg as lint cleaning stages increased from 0 to 3, but the number of fragments was reduced only slightly. In this study, which included varieties of moderate seed-coat fragment producing potential, weather (year) influences were more important than harvest or varietal factors.
