Nothing wrong with OP if that is what you want to do.
As the others say, think it through.
I see on this site a fella has a year old bag of OP for sale for $75.
I can buy some Dekalb older but good corn for $250-275.
Or my small seed breeder I buy most of my corn from at $220-230.
I can get non-traited (non-gmo) hybred corn from them for $90-120 a bag.
All of these corns will get me 175-225 bu an acre depending on my soil and rainfall.
The OP corn will top out at 85-125 bu an acre.
Be sure you get what you pay for. If you are just putting in an acre for the deer to eat, or just planting for fun, or have some ground that probably won't yield any corn but you want to plant it anyhow, then nothing wrong with the OP. Or if you want to save your own seed, or organic heirloom type of stuff, nothing wrong with picking OP to grow. In some cases OP will outyield the hybreds for silage, so another good reason to look at growing them.
But only just, if the cost of the bag of seed is what you are looking at, you might really hurt your yields and income...
That $90 bag of untraited hybred corn is going to yield a lot more than the $75 OP bag of corn....
