The effects of sole and mixed cropping of different annual medic cultivars on biomass and seed bank reservinvestigated in Climatic Research Station of Khoramabad during 2001 and 2002. The treatments were statistically evaluated in a Randomized Complete Block Design with three replications. The treatments consisted of sole and different paired combinations (50:50) of 6 annual medic species in mixed cropping system. Mixed cropping was superior to sole cropping because of better biomass production and stronger seed bank leading to a better re-establishment of annual medic pasture in a ley-farming system. Mixed cropping of Medicago truncatulla cv. Caliph with Medicago scutellata cv. Robison was the most successful treatment in regard to biomass as well as seed production. However, Medicago truncatulla cv. Caliph produced the highest seed yield in sole cropping among the other cultivars.
