In order to know the effect of organic-mineral fertilization on the productive performance of drumstick tree, on a euthric lixiviated Ferralitic Red soil, the following treatments were evaluated: T₀ = absolute control; T₁ = 0,6 t ha^-1 of fertilizer 9:9:12 (54 kg N, 54 kg P₂O₅ and 72 kg K₂O) at planting and 130 kg ha^-1 of urea (61 kg N) per forage cutting; T₂ = mixture of 0,3 t ha^-1 of the formula 9:9:12 (27 kg N, 27 kg P₂O₅ and 36 kg K₂O) with 4 t ha^-1 of cattle manure at planting and mixture of 65 kg of urea (30 kg N) with 2 t ha^-1 of cattle manure per cutting; and T₃ = 8 t ha^-1 of cattle manure at planting and 4 t ha^-1 of cattle manure per cutting. The design was randomized blocks with five replications. The results of the five cuttings indicated response to the three fertilization variants; the organic-mineral combination (T₂) stood out, producing the highest yield of total dry matter (20,11 t ha^-1), followed by the mineral variant (14,29 t ha^-1) and the organic one (13,46 t ha^-1 año^-1). The control only yielded 10,57 t ha^-1. The annual dry matter yield of leaves had a similar performance, with the best value in T₂ (11,34 t ha^-1). It is concluded that under similar edaphoclimatic conditions variants of organic-mineral fertilization can be used to improve the forage yield and quality of this plant
