s. Some irrigation can be provided to the plants, but it is important to remove the water through an effective drainage system, as excess water may prove to be detrimental for the growth of the plant. When not grown in adequate shade, the kola nut plant responds well to fertilizers. Usually, the plants need to be provided with windbreaks to protect them from strong gales.
Kola nuts can be harvested mechanically or by hand, by plucking them at the tree branch. Nigeria produces 52.4% of worldwide production followed by the Ivory Coast and Cameroon. When kept in a cool, dry place, kola nuts can be stored for a long time.
