Typically greater ear height and total plant height of the same hybrid can be indicator of higher yield because the plant has produced more vegetative material in order to photosynthesize more resulting in more seed production. These physiological measurements are not always perfect indicators of yield but are generally considered as a fairly reliable method for indicating yield differences during the growing season. Trials were weighed at the time of combining. The results matched what we were seeing in our in-season measurements.
