To add to what RG Martin said.
Yup you can plant the OP corn and get 100 Bushels per acre. At $5 abu. thats $500.
Or you can plant the pioneer at $120 an acre for seed and get 150 bushels an acre. That equates to $750 an acre. $250 more than the OP.
You couldn"t get the op for free and be ahead.
Just making sure you think it all through.
