The value of rotations of 'Florunner' peanut (Arachis hypogaea) with American jointvetch (Aeschynomene americana) and southern blight (Sclerotium rolfsii) was studied for 3 years in an experiment in southeastern Alabama. Peanut yields following 1 or 2 years of partridge pea were equal to yields obtained from peanut monoculture with aldicarb application at planting and were higher than yields of peanut monoculture without aldicarb. Peanut yields after 2 years of jointvetch also were higher than those from monocultured peanut without aldicarb. Jointvetch and partridge pea both suppressed development of M. arenaria when either was grown for 2 years instead of peanut without aldicarb, but partridge pea was more effective. Suppression of M. arenaria populations by growing partridge pea or jointvetch instead of peanut for 2 years was measurable after a subsequent peanut crop was grown. Partridge pea reduced populations more than jointvetch. Partridge pea and jointvetch rotations had no ind
