So...this year I planted a patch of soil out by the street with wheat and helianthus tuberosus. Only 5 helianthus came up, but most of the wheat did. The bare patch that didn't come up was planted with torpedo (red) onions, which are only now giving me some good onion-leaf cuttings.
This is my best-sun-exposure ground, but since it lies between the street and the sidewalk, I didn't want to plant anything "sexy" that would be picked by passersby, of whom we have a good number! So...wheat, onions, etc.
I was successful in this very limited experiment in growing wheat. I planted it on 5-inch spacings (intensive method), with HT randomly interplanted. (Next year, 2-inch spacings for the wheat; too much dirt was unproductive, and I have only 24 + 15 + 20 square feet, or just under 60 sq.ft. of available "land.")
But...how do I separate the wheat grains from their "ears" (awns, bearding)? I've read and read on the 'net about threshing with flails, having animals tread on grain on hard earth, stomping it on concrete, even found plans to convert a leaf/branch chipper into a thresher. However...
I have less than 2 lb (est.) net grain, so a small, hand- or foot-powered method is all I need.
Any ideas as to whether using a marble rolling pin on the grains would help? You know: place the plant heads between two lint-free kitchen towels and mash 'em with the rolling pin? (Bear in mind that I can't do this for very long at one time; carpal tunnel and other tendon problems are always lurking in the background, just waiting for me to get *real involved* in something interesting....)
