I spent about four hours searching for answers to my original question early this morning. So far, it looks like dry bush beans yield about 1500 lbs of shelled beans per acre. For dry pole beans, one Brittish gardener got 700grams (about 1.5 lbs) of beans from six Cherokee Trail of Tears pole bean plants during a good growing year in 2012.

Considering this would mean he got about 117 grams (4 oz) of beans per plant, this yield seems reasonable compared to the 2.25-3 oz of beans I got per wooly bean plant (Strophostyles helvola) this year. The problem with these calculated yields is that when they are scaled up, assuming a planting rate of 86,388 plants per acre and the yield remains constant per plant, I would get 21,266 lbs of Cherokee Trail of Tears beans per acre and about 15,000 lbs of wooly beans per acre. Such yields seem to fall on the lower end of potato yields per acre. I must be getting something wrong when I made the calculations.
