Dr. Joe Lauer, University of Wisconsin Corn Agronomist, takes you into the field to show you how to determine if pollination has occurred using the ear shake test. By knowing if pollination has been successful or not, a grower can better choose when to harvest for maximum forage yield during a drought or otherwise stressful season.
Typical management options and uses are available for corn that has successfully pollinated. If pollination is unsuccessful, we are usually left trying to make the best of a bad situation. For corn growing in Wisconsin, Dr. Lauer discusses pollination typically occurring before August 1 and why that is key during this dry season.
