Corn grows on "bushes" - you heard it here!

Apparently, corn grows on "bushes." If you don't believe me, take a look at this:

"Mr. Coxe said crop yields around the world need to increase to something close to what is achieved in the state of Illinois, which produces over 200 corn bushes an acre compared with an average 30 bushes an acre in the rest of the world."

Once, I can pass off as a simple typo. But twice in the same sentence? I think that's a bit more like some kind of cluelessness at work.
