The stem-nodulating tropical legume, Sesbania rostrata, was grown for seven consecutive years for 35-42 days in the pre-rice niche of traditional Casamance (south Senegal) rainfed lowland fields under the management of both researchers and farmers. The incorporation of about 25-35 Mg/ha of fresh green manure (GM) biomass resulted in an average N accumulation of 90-150 kg N/ha. Lowland rice-grain yields increased from 2 Mg/ha in weedy fallow control plots to about 4 Mg/ha where seed-inoculated S. rostrata was incorporated. Sesbania rostrata GM technology may contribute to increase rice production in casamance and warrants to be extended to regions with similar conditions. (Résumé d'auteur)
