This is an upright-growing annual legume reaching to 8 feet, grown only for turning under as a soil-improving crop. It produces a heavy tonnage for this purpose. On irrigated lands in the Southwest it is extensively grown as a summer crop and turned under prior to planting winter vegetables. It is grown mainly in areas of high summer temperatures.
