It does look a little bit short. On the other hand some varieties of corn are short. Once the tassle begins to open the corn will get noticably taller.

You may have an issue with pollenation. Corn pollenates best from having a block of several corn plants vs indivdual ones... because there is more pollen dust to blow across and onto the silks. (However, I can't see the area nearby.)

Agree with Grandad.

grandad i plan on doing the hand pollination thing because i don't have very much corn growing. Thank you for the reply

You can hand pollinate the corn. Rub the tassles on the new silk. Search the forum for more details...

Mine are growing and maturing very short this year too. They are both supposed to be tall varieties. It's said this is a cultural phenomenon. The good news is, short as they are, they pollinated fine, the ears are completely filled and the corn is maturing normally.

They will grow quite a bit after they tassle. I've had mine do that some years - I'm not exactly sure why. But it always ends up approximately the right height at maturity, and the corn itself is mighty fine eatin'!
