Résumé : An experimental station on woody plantations was set at Nianga, near Podor in the Senegal River Valley, in 1981. It permitted to perfect the irrigated intensive forest plantation methods (water quantities, type of irrigation or spray, suitable species in order to provide different products, intensive wood cultivation methods). In the conditions of the irrigated land cultivation in the Senegal Valley, the best species for fire wood are Eucalyptus camaldulensis, E. tereticornis, Prosopis juliflora, Leucaena leucocephala. The trees must be planted at the density of 3300 trees per ha (spacing : 1 x 2 m), stripe irrigated (1 500 cubic meters per ha and per year), harves ting rotations : 3 years (only two years for fire wood production with Eucalyptus) . Three successive harvests by coppicing are possible on an industrial scale, the average yield is about 20 to 25 cubic meters per ha and per year with not much selected trees. With genetic improvement these yields can be raised over 30 cubic meters per ha and per year on an industrial scale. On an experimental scale, a yield of 40 cubic meters per ha and per year has been already obtained. The priority for the application of these technics for development, is to promote them to the farmers, particularly in village scale irrigated lands in the Senegal valley.
