Summary: This presentation will help consultants, growers, and other practitioners throughout the Cotton Belt to identify factors contributing to higher cotton leaf grade values. However, most of the data presented will focus on research trials and experiences from Southern Texas. Cotton fiber quality has become much important to the U.S. cotton industry in the past 10-15 years as more and more of our cotton is competing in the export market. Contamination of the cotton lint by leaf and bract material, quantified as leaf grade value by the HVI analysis, is one fiber quality measurement where the U.S. cotton producers are receiving significant price discounts. This presentation will discuss the factors contributing to higher leaf grade values in cotton and recommendations for minimizing cotton leaf grade values.
