You’ve all heard the saying “knee-high by the fourth of July” to describe the progress of a corn crop. It’s a phrase many folks still refer to today. But as the photo below shows, that saying is now laughable. In fact, if you’re a Midwest farmer and your corn is now knee high, it’s probably in big trouble. So where did the adage come from? It likely started before hybrid seed corn was invented, when planting dates occurred in late May/early June and when mature corn plants were much shorter. With the advent of hybrid seed corn, and adoption of synthetic nitrogen, there was a meteoric rise in yields and corn growth. My corn was planted on May 4th, and on July 4th it was tasseled and twice as high as my son’s girlfriend!
