Precision agriculture technologies are providing an opportunity to manage fields as separate units instead of one management unit. These technologies are valuable because soil and crop parameters often vary within a field. Relatively little spatial variability data are available for cotton. This experiment was conducted to study the variability of an irrigated cotton field. At 70 points within a field, cotton yield and quality parameters were determined. Yield and yield components were more variable than were quality components. The variability could be even greater in production scale fields. Precision agriculture could provide ways to reduce the amount of variability in production cotton fields while increasing the production efficiency.
