This study examined the potential to adapt the ley farming system used in Australia to dryland cereal production in Montana. The ley system alternates a grain crop with a self-seeding forage legume. The legumes tested in this study included 5 Australian medics, 7 subclovers, 2 lupins, fababean, and a native Montana black medic. One full cycle of the system was completed. All grain yields (spring wheat) were higher after the legumes than after fallow. Soil water to 120 cm was similar in all plots at wheat planting. The black medic treatment had the highest water use efficiency (100 kg grain/cm) and fallow the lowest (55 kg grain/cm). There were higher levels of soil nitrate after the legumes than after fallow. Re-establishment of the legumes after wheat ranged from 3 to 93% ground cover, with black medic being the highest. Overall, black medic from Montana performed best in this study.
