Figure 3. The Planting Date Planner tool (http://agroclimate.org/tools/yieldRisk/) helps producers determine which dates carry more or less yield risk depending on the location, crop, soil type, and ENSO phase. This tool is based on the results of numerous crop growth simulations. Crop choices include varieties of corn, cotton, peanut, potato, and fall, spring, and winter tomatoes. Counties in Florida, Georgia, or Alabama can be selected. Three county-specific soil choices are available. The figure above shows the results of selecting three planting date options as indicated by the check marks next to the dates in the upper right portion of the figure. Notice that the earliest planting date (April 16) gives the greatest likelihood for high yields.
