7786. Engel, R., L.E. Welty, R. Lockerman, J. Bergman, G. Kushnak, L. Prestbye, and J. Sims. 1987. Annual legumes and cereal grain rotations in Montana.. Montana AgResearch 4(3):1-4.
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.
