CASE2: A physiological production model for cocoa

Submitted by Mink.Zijlstra on
    Cacao Simulation Engine (CASE)2
    Program type
    FSE simulation model
    Available since

    The CASE2 simulation model uses information on daily weather (radiation, rain, vapour pressure and temperature), soil characteristics (texture classes of different soil layers), plant characteristics (physiological and morphological characteristics) and cropping systems (tree density, tree age and shade regime) to estimate growth and yield of cacao trees in a plantation.

    Applications & Use

    This model is produced within the framework of a research programme on modelling of growth, yield and quality of cocoa. The overall objective of this programme is to increase the understanding of cocoa production in relation to environmental conditions and cropping systems. A better understanding of cocoa production systems may assist to improve cocoa production systems in producing countries.
