Cacao crop is under pressure due to the high global consumption of this commodity, a fact that exposes the great need of technical precision for nutritional diagnosis and fertilizer recommendation in the plantations. The objective of this work is to review and to use the available information in the literature and the opinion of the cacao crop experts to establish the Wymore's standardized scoring functions (SSFs) for the main macro and micronutrients in cacao leaves. The critical limits of the SFF of the optimum type were defined for the mineral nutrients N, K, P, Ca, Mg, S, Fe, Zn, Cu, B and Mo, and the SFF "more is better" type was applied for Mn. This SFFs can be used to know the individual status of each nutrient or incorporate linear combination models applied to a system for foliar nutritional diagnosis of the cacao crop.
