Zusammenfassung:Agroforestry tree domestication for forest restoration and fruits and nuts production is ongoing in West and central Africa. It is focused among others on vegetative propagation techniques to capture the superior phenotypes of individual trees. Cola anomala which is a priority target for domestication has been reported amenable to vegetative propagation through rooting of leafy stem cutting, but the rooting efficiency of cuttings collected from non-fertilized stockplants was very poor. The present study addressed the effect of a range of granular NPK 20-10-10 doses (0, 0.5, 1, 2, and 5 g/plant applied at 2-month intervals for 8 months) on growth, total nitrogen content, available carbohydrate content and amino acid content of C. anomala stockplants and the subsequent rooting ability of leafy stem cuttings. Results showed that perseverance fertilizer applications significantly affected growth ( p
