Friend of mine turned me on to this Sat; he talked about harvesting the tops several times a year,and leave the tubers.Compared it with alfalfa, which I want to check out. I'm surprised these guys are taking the tubers, too. Brrr :>)
-------------------------------------------------------

Jerusalem artichokes (sunchokes) have been widely promoted as an energy crop and had the second highest alcohol production potential in this series of experiments. However, the species seems to have several disadvantages which may well outweigh its high-yielding potential. The crop was relatively easy to grow but difficult to harvest and store. The tubers are tightly attached to the crown of the plant and, when dug by machine, come up as a mass of tubers, crown tissue, and soil which does not separate well like potato or sweet potato. Thus, much hand labor was needed for harvest. In addition to that, the tubers do not store well after digging and must be utilized quickly to prevent spoilage and loss. However, the tubers do keep well in the soil and presumably could be stored in the field and dug as needed whenever the soil was not too wet. Another problem is that they may become weedy.
