The U.S. standard bushel weight for buckwheat is 52 pounds per bushel. The cover crops are not harvested for cash sale, rather they provide conservation benefits, and may help reduce input costs. As a cash crop, buckwheat uses only half as much soil moisture as soybeans (Myers and Meinke, 1994). Buckwheat is sometimes planted in rows next to fall plantings of cabbages or other Brassicas; the buckwheat attracts beneficial insects that eat aphids, preventing the aphids from infesting and harming the cabbage.
