Tested tangier flatpea, indianhead lentil, fababean, field pea, and Austrain winter pea at several locations. Data suggest that annual legume green manures contributed about 40 lb N/ac, and increased wheat yields more than the addition of 54 lb N fertilizer on wheat stubble. Moisture greatly affected yield after legumes. Choice of annual legume depends on relative seed cost. Suggest indianhead lentil as most promising species. The value of the N it fixes comes close to the seed cost. Three management systems are proposed.
