The objective of the present paper was to evaluate the survival of planted leguminous trees to restore degraded areas and yields of maize and cassava in traditional farming system. The trees species Acacia angustissima, Clitoria racemosa, Inga edulis, and Acacia mangium were planted at spacing of 1 m x 1 m, 2 m x 1 m and 2 m x 2 m. Sclerolobium paniculatum was planted only at spacing of 2 m x 1 m. The maize, remained in the cropping system during the first four months, and it was considered as monocropping phase and, yielded 1,890 +/- 32 kg ha-1. The survival of planted trees was not negatively impacted by the presence of agricultural crops. Regardless of the spacing, the planted trees did not cause a negative impact on dry weight of cassava root. There...
