You know I think you are right and that this often repeated answer on the internet may be wrong or maybe the yield you can get using permaculture type methods at home is drastically lower than professional farmers using fertilizer and industrial equipment (very likely).

Let's say a home grower could maybe get 1/4 of a professional farmer's yield. 45/4= 11.25 bushels per acre is 675 lbs per acre, which would be enough for four people for a year.

It makes me feel better about the feasibility of growing my own grains and living on it in an apocalypse. I've always wanted to try growing a field of wheat or something in my backyard. Maybe I'll try it someday. I've often wondered if garden grown grains and bread would have the same massive difference in quality and taste that you get with a homegrown tomato vs. store-bought.
