Requirements of Stylosanthes guianensis (Aubl) Sw in lower Ruzizi and Mosso (Burundi). This paper describes the requirements of Stylosanthes guianensis in two ecological regions : Mosso (1 280 m alt.) and lower Ruzizi (800 m alt.). This legume was introduced in 1953 into the grasslands of the east and in 1970 into lower Ruzizi, with the aim of improving the value of the natural pastures using leguminous plants. At Mosso, soil and climatic conditions were favourable for Stylosanthes and it grew well. However, since 1981. Anthracnose has severely reduced its growth and until a solution is found its general introduction will not be possible. In lower Ruzizi plant development was limited by low rainfall (670, 4 mm per year) and soils with a low water retention capacity (sand dunes). For this region, it is necessary to identify cultivars resistant to drought and devise a method of establishing these cultivars on sand dunes.
