There is apparently considerable variation in pole bean dry seed yield. I use wider spacing for most pole beans - 12" between plants is my default. I grow many beans for seed, and (usually) record the results. My over-all average is over 6 ounces per plant, with some varieties more than twice that. A row of "Striped Cornfield" had an average of over 11 ounces per plant, and "Brita's Foot Long" averaged over 10 oz./plant. I've had single plants of several varieties yield nearly a pound of dry seed.

It's worth noting, though, that soil fertility has a major impact. I have 3 plots on two widely separated properties, and the same variety will perform differently in all 3 plots.

I grew a 20-foot row of "True Red Cranberry" (with 12" spacing) and wasn't terribly impressed by its yield either.
