I usually have 2 bines per rope and train 4 bines per plant. Production will depend on variety, soil fertility and your ability to combat weeds, insects and fungus/mold. 1 bines per plant will lead to less production of cones. I'd run at least 2 bines per plant, test your soil, fertilize per recommendations per the soil test, learn about insects, and the rest. Walk your hop yard weekly looking for problems.
