In the peanut basin, a major agricultural region in Senegal, crop yield has gradually declined in relation to soil degradation. Land use for food crops is a big in priority represents a big constraint for the intensive production of Jatropha curcas, a tree planted for biofuel. This study examined the possibility of designing appropriate agroforestry systems combining food crops and J. curcas. It was conducted in Nioro in the sub-humid zone of Senegal. Four treatments in complete randomized block design with three replications: groundnut-only crop, Jatropha curcas-only crop, groundnut-Jatropha curcas in combination at an interval of 6 x 6 m, and a groundnut-Jatropha curcas combination at an interval of 3 x 3 m were compared. The influence of Jatropha curcas-based agroforestry systems on soil water dynamics was similar to that of a groundnut-only cropping system. No depressive effect on yields of groundnut and Jatropha was noticed.
