Sustainable production of Garcinia kola can be achieved through the establishment of its plantation with the right silvicultural requirements. The growth response of Garcinia kola (Heckel) plant under a Tectona grandis L. plantation and open field was studied for three years. The experiment was laid out in a Randomized Complete Block Design (RCBD) involving three replicates per treatment. The treatments were shade from Tectona grandis (Teak) and control (open field without shade where fresh clear-felling/harvesting of Tectona grandis (Teak) has just been carried out). Measurement of treatment effects on growth of Garcinia kola commenced six months after planting and was repeated at six-month intervals, while soil temperature was measured at two week intervals. Significantly (P ≤ 0.05) higher differences were observed after the first year in height, collar diameter, and crown width on the shaded plant. The soil temperature for the shaded field was significantly (P ≤ 0.05) lower than the control field. Hence it is recommended that sustainable production of Garcinia kola through plantation establishment should be done under the shade of older trees.
