You live in Texas and corn production there is poor compared to the Midwest. We had a very dry year but yields in this area were around 150Bu/acre. 300 Bu corn has been raised in parts of Iowa and Illinois for several years now. The goal now is to break 400 Bu/acre. Corn and bean yields continue their upward trend. There was a guy in SW Missouri that raised 154Bu/acre soybeans on a small irrigated plot this past year. Ethanol is the not the total solution to foreign dependency but it does have a viable role to play.
I noticed that U of Illionis has a 44,000 plant per acre project that should be nearly finished. Could be an interesting yield in raw bushels.
