Advantages, disadvantages and desirable characteristics of shade trees for coffee, cacao and tea

  • John Beer

Abstract

A review is made of the ecological interactions that occur between shade trees and the perennial crops: coffee (Coffee spp. L.), cacao (Theobroma cacao L.) and tea (Camellia sinensis L. Kuntze). These interactions are classified firstly as advantages or disadvantages, and secondly as: effects on crop management; effects on the hydrological cycle; effects on pathogens, insects and climatic conditions; and effects on soils. References are given for the 20 advantageous and 16 disadvantageous consequences of using shade trees, emphasizing publications that provide original data and useful methodologies. Finally a check list of desirable characteristics for perennial crop shade trees is presented.

Resumen

Se hace revisión de las interacciones ecológicas que ocurren entre árboles de sombra y los cultivos perennes: café (Coffee spp. L.), cacao (Theobroma cacao L.) y té (Camellia sinensis L. Kuntze). Estas interacciones fueron clasificadas en primer nivel como ventajas o desventajas, y en segundo nivel como: efectos sobre manejo de los cultivos; efectos sobre el ciclo hidrológico; efectos sobre patógenos, insectos y condiciones climáticas; y afectos sobre los suelos. Se dan referencias para 20 consecuencias ventajosas y 16 consecuencias desventajosas al utilizar árboles de sombra, dando énfasis a publicaciones que proveen datos originales y metodologias útiles. Finalmente se presenta una lista de las características deseables para árboles de sombra para cultivos perennes.
