Another option would be to have an area layer with the different pivot and dry land maps on one layer. Then display the desired harvest/yield data map. Go to the Layers Tab under the Mapping screen and from the View box, highlight desired attribute, such as Dry Yield. Then click the Add View button. Place dot by Area. Browse to the Area Layer for this field that has the pivot and dry yield polygons and click OK. You can check the box to create a new composite layer. Click OK. Now you will get a new background layer showing the average yield by polygon, that can add labels and print, if need be.
