Reading in the local Ag newspaper, Illinois Agrinews, average corn yields in McLean County Illinois (prime corn land) are expected to average 233 bushels/acre (15.7 tonnes/hectare). That's simply amazing.
Me, with my organic methods, no chemical weed, insect or fungal controls and using open-pollinated seed, hope to get 60 bushels/acre (4 tonnes/hectare). The last two years I got 59 both years.
By historical averages I am doing much better than pre-modern standards. Averages across the US before modern agriculture started in the 1930s was 30 bushels/acre, but I am in the corn belt and that number was nation-wide including much poorer land and climate areas.
I would dearly love to do a side-by-side comparison of my corn and modern hybrid seed under equal conditions, both in a high-input field and also in my organic plot. Maybe next spring...
