Technical Abstract: This study examines trends in United States upland cotton yield productivity since 1980. The overall objective of the study was to document changes in productivity over this time period with a special emphasis to measure and examine changes in genetic gain. To meet this objective, on-farm and replicated variety trial yield datasets were analyzed and interpreted. Clearly, these analyses suggest that yield productivity and genetic gain have occurred since 1980. Trends and factors will be discussed that are associated with increased yield over this time period.
