Abstract

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.

用于可可作物叶面营养诊断的 Wymore 标准化评分函数

摘要

由于这种商品的全球高消费量,可可作物面临压力,这一事实暴露了种植园对营养诊断和肥料推荐的技术精度的巨大需求。这项工作的目的是审查和使用文献中的可用信息和可可作物专家的意见,为可可叶中的主要宏量和微量营养素建立 Wymore 的标准化评分函数 (SSF)。对矿质养分 N、K、P、Ca、Mg、S、Fe、Zn、Cu、B 和 Mo 定义了最佳类型 SFF 的临界限值,并应用 SFF“越多越好”类型锰 该 SFF 可用于了解每种营养素的个体状态,或将线性组合模型应用于可可作物的叶面营养诊断系统。
