Describes the "new world" and "old world" lupin species and their general characteristics. Lupins are used as a green manure/cover crop, forage, and grain. Some species are similar to soybean in protein. Others still have alkaloids that have to be removed before consumption. Lupins are now grown on 500,000 ha in Australia as a rotational crop. Their use has expanded in Brazil, also, particularly for soil protection and green manure. They can fix 80 kg N/ha.
