​This presentation will help consultants, growers, and other practitioners throughout the Cotton Belt to identify factors contributing to higher cotton leaf grade values. Cotton fiber quality has become much important over the past 10-15 years with over 85% of the U.S. cotton being exported. 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 cotton producers are receiving significant price discounts in some years. Previous research has shown that numerous factors contribute to the leaf grade values; however, it is difficult to link anyone specific factor directly to higher leaf grade values. The cotton plant characteristics, different harvest-aid scenarios, and environmental factors are discussed in the presentation.
