Abstract: Most landrace legumes originated in Africa and Asia and their cultivation is as old as the existence of man`s discovery of farming. Landrace legumes found in the humid and sub humid tropics with diverse climatic differences come from different groups and are found among wide range of species. Depending on the species, some are food/grain legumes, shrub or tree legumes. The major ones include mucuna pruriens, Phaseolus lunatus, Sphenostylis stenocarpa, Mucuna sloanei, Pentaclethra macrophylla, Tetrapleura tetraptera and Anthonata microphylla. They have potentials for man in his food and nutrition, soil fertility improvement through nitrogen fixation and mineralization of the decayed shoots and roots in the soil. They are important in soil conservation, farming systems and in medicine, agro forestry, for erosion control purposes and in culture of the people. Legumes are important crops and their nodules interact with rhizobia species of bacteria to fix nitrogen in the soil. They have high economic potentials when intercropped with yam/maize/cassava and as sole crops.
