Interpretive Summary:

Technical Abstract: This abstract will summarize the methodology used to develop a yield stability map for a field. We proposed that there exist yield stability patters for commercial field crop production which growers can use to optimize crop production while minimizing inputs. The methodology uses multiple years of multi-crop yield monitor data and a high resolution, high density LIDAR digital elevation map of the field together with GIS and image processing and SAS® statistical analysis to produce detailed, multiple component GIS map which shows transitions for low yielding areas of the field through medium yielding areas to the most productive high yielding areas of the field. The statistical procedure makes use of krigging, cluster analysis, and simple quadratic regression to produce a statistically sound three component map showing low-, medium- and high-yield zones in the field.
