Historically, the center pivot has been used by a farmer/operator to apply a selected depth of water uniformly across the entire field. Changes in technology have occurred that give growers the ability to apply differing amounts of water and products carried in the water to different zones along the pivot and sectors around the field (Perry 2005). This paper will discuss results from the summer of 2010 of a commercial center pivot equipped with the Valley Variable Rate Zone Control package. The paper will also review potential payback. It will close with a discussion of future needs for variable rate irrigation.
