Three perennial legumes (Macroptilium atropurpureum, Rhynchosia totta and Rhynchosia minima) were evaluated in a glass?house under uncontrolled environmental conditions for herbage, root and nodule yield on two soils and on river sand under six fertilizer treatments. Phosphorus appeared to be the main nutrient element deficient in the soils. The three legumes responded differently to treatments on the three rooting media and the reaction of species to the soils also varied.
