Scheduling Irrigation on Cotton using Internet-Based Woodruff Irrigation Charts

J.C. Henggeler

ABSTRACT

Irrigation scheduling is important to insure yield loss is minimized and profit maximized. Some methods of scheduling can be time consuming or require expensive sensor systems. A simple scheduling approach developed for Missouri based on historic weather records is referred to as the “Woodruff Chart”. Originally this was a paper-based chart, and now this method is available to producers over the Internet. Initial results indicate users of the Woodruff method are not obtaining yields as high as those using another irrigation scheduling program, the Arkansas Scheduler; however, these results are based on a very limited number of producers (two over a four year period) using the Woodruff method.
