Legume biomass and seed yield were best for fababean, fieldpea, and chickpea. Potential for use of legumes for hay or silage. Barley yield after legumes was comparable to barley after fallow, and better than barley after barley or wheat. N contributions to the cropping system, except for field bean, were greater for legumes than for fallow. High N fertility levels from legume N plus fertilizer N resulted in premature soil moisture depletion. Optimum rotation performance will depend on balancing nitrogen fertility with expected available moisture.

Montana researchers examined the performance of several grain legumes (dry pea, chickpea, lentil) and their effect on a subsequent barley crop. Dry pea production was the highest. A subsequent barley crop rsponded to added N fertilizer at three out of six sites. Barley yields following legumes were generally equal to or greater than yields following fallow. The annual legumes contributed to soil N and reduced the fertilizer N needed to reach maximum yield by 40-55 lb N/ac when compared to recrop barley. This translated into savings of $10-14/ac for fertilizer N.
