Our corn crop on the farm here in northern Ohio has consistently exceeded 200 bushel per acre.20 years ago this was unachievable here.Some of the gains are from genetics but I think CO2 levels play a part too.

Of course it does.
I used own and operate a greenhouse, and had a CO2 emitter. Ran on propane, plants loved it, co2 levels were about triple what is in the atmosphere currently.
Doubled my turnover. Not profitable without it.
Atmospheric Co2 is free fertilizer.
Boy 20 bushels per acre is amazing. Not too long ago that type of yield would have won a national prize.
My great uncle, who started corn ng in the 1920s, said that his yield had increased 16 times by 1990.
make that 200 bushels. ....sheesh
