Interpretive Summary: Cotton varieties respond differently to gin cleaning machinery, making it difficult to optimize cleaning for each variety. This study evaluated the impact of one and two stages of saw-type lint cleaning on the market grade and monetary value of 44 cotton varieties grown in different locations near Stoneville, MS. The leaf grade was improved on 33 of the varieties, and one stage of lint cleaning was the most profitable. Results of other studies suggest that two stages of saw-type lint cleaning is sometimes the more profitable for these same varieties. Thus, each cotton must be "prescription" ginned based on its merit, and likely must be accomplished with an automated system.

Technical Abstract: Comparisons of the ginning performance of cotton varieties are normally done with two lint cleaners; however, many varieties respond very favorably to only one stage of saw-type lint cleaning. This study compared fiber properties of cotton processed with one and two stages of saw-type lint cleaning. Evaluation of 44 varieties grown near Stoneville, MS, on two soil types indicated significant differences between the varieties for mos properties measured by the High Volume Instrument (HVI) classing system. Significant differences also occurred between fields (growth locations). One stage of saw-type lint cleaning was the most profitable for the farmer. These results indicate the potential for improving cotton fiber quality parameters based upon the option to use fewer than the current stages of saw-type lint cleaning.
