Picked mine a couple weeks back, 2, 2nd year Chinook plants gave me an oz combined, and my 2nd year Fuggles and Golding gave me an oz combined also. Wasn't much for the Golding, so just threw what little there was of it, in with the Fuggles, figured I would use them in the same recipe anyway.
Friend of mine had a Cascade plant that she was using to make soap, but she found another source for her hops, so she had it pulled out. I fortunately got there in time to grab the bines, which gave me about 4.5oz of hops after drying, unfortunately, I didn't get there in time to grab the roots, as it was probably a 4-5yr old plant....would have been nice to have!
Our oven worked well for drying them, set on convection bake at about 150F, and dried them out nicely.
