Seven legume species were subjected to evaluation of their adaptability to surface-sowing such as broadcasting and pellet-sowing in the burnt savanna in Colombia. Suitable legume species and sowing methods were identified in each of the three experimental sites, which varied in soil types. The findings obtained are as follows: (1) Stylosanthes guianensis was suited for both broadcasting and pellet-sowing: (2) Under the infertile condition of soil such as sandy clay loam, broadcasting was not suited, pellet-sowing of S. guianensis might be recommendable; (3) Under such fertile soil condition as light clay or silty clay soils, broadcasting of S. guianensis well fitted; (4) Stylosanthes capitata and Desmodium ovalifolium would have possible suitability for broadcasting in fertile soil, although some problems caused by microelement deficiency for S. capitata and insect damages for D. ovalifolium should be overcome; (5) Centrosema acutifolium could be properly sown with pellets, although some microelements had to be added to pellets; (6) Flemingia macrophylla, Purearia phaseoloides and Stylosanthes macrocephala were not suited for surface-sowing; and (7) Broadcasting produced more legume plants in number than the pellet-sowing did, while the size of individual plants with the former was smaller than that with the latter, showing efficiency of fertilizing by pellet.
