Overview

To palliate the problems of energy and service woods shortage and decrease of soils fertility, studies are taken up in forest transition zone of Côte d'Ivoire on 20 species of dry zones arborescent leguminous. Two important objectives were defined. It is to first, identify leguminous adapted to dry areas of Côte d'Ivoire; then set pulses management technics for their use in reforestation. To do this, plants from nurseries were planted and monitored by periodic inventories. The survival, the adaptability, the vigor and the volume of wood leguminous species were evaluated. A coppice was made after coppicing trees at 30 cm from the ground at the beginning of the rainy season. Seven years after planting, 18 species have survived. Leucaena leucocephala, Leucaena shannonii, Albizia guachepele and Enterolobium cyclocarpum present high potentialities for reafforestation with a plantation strike root rate superior to 65 p. c., a middle diameter between 9.7 and 16.3 cm and woods productivity superior to 10 m^sup 3^.ha^sup -1^.year^sup -1^. Cubage equations have been established for 11 arborescent leguminous species to estimate the production of wood in the transition zone. The wood technical exploitability ages of species plants are situated between 4 and 7 years. Some species react favorably to the treatment of coppicing.
