Freeburg, IL | One nice thing about a corn plant is that when it is planted later than normal, it will make up time. I liken it to waking up late on Sunday morning. If you only have 30 minutes to get ready and get out the door, you can still get a quick shower, shave and get dressed just as you would if you had one hour or 2 hours or whatever.
The corn plant pokes through the ground and goes, "holy crap! I've got to get with it!"
Purdue and Ohio State have done a few tests. To give you a quick summary, their results show that planting to emergence time over a 5 week window is cut in half and emergence to silking was reduced about 9 days for late planted corn. However, silk to blacklayer will be extended a few extra days.
Nielsen and Tominson reported that when planting is delayed after May 1, the number of GDUs from planting to blacklayer decreases 6.8 GDUs per day of delayed planting. | |
