How many bean plants will corn / sunflower support?

I planted a section of my garden three-sisters style this year: corn, squash/pumpkin, and pole beans (for dry harvest).

I also have a 25' row of "Mammoth Gray Stripe" sunflowers (9-12 footers) in the back of the garden where I've planted beans among the sunflowers. I had to saw down a similar variety of sunflower last fall, so I'm pretty sure these are going to be sturdy enough to carry a heavy load.

I started the corn and sunflowers first, thinking that they'd get a head start before the beans start to climb.

My question is:

What's the right ratio of beans to corn/sunflower? I.e. how many vines is each plant capable of supporting?

Yummm...black turtle beans. I'd suggest only 1 to 2 bean plants per sunflower so they don't block out too much sun, and since sweetcorn plants have shallow roots, only 1 bean plant per corn, particularly if you get windy weather in the summer. I remember my parents' sweetcorn crop in SE Pennsylvania - with no beans adding weight to t

I remember my parents' sweetcorn crop in SE Pennsylvania - with no beans adding weight to the corn - suffering damage from windy summer storms on an annual basis. You also don't want to hamper the pollination of your corn crop too much.
