This experiment has been added by the GLTEN Curators using existing published sources.
To study conventional and organic cocoa production in monocrop (full sun) and agroforestry (shaded) systems.

Design period: (2008—)

Design Type
Randomized complete block design
Data are collected for cocoa yields and by-crops, labour time, costs of agronomic inputs and income from harvested products, tree growth, pest and diseases, phenology of cacao trees, climate and soil fertility.
Design description
Gross trial plots are 48m x 48m, while net plots are 24m x 24m. The experiment has the following 6 treatments replicated 4 times: i) monoculture, full sun (in the cocoa production phase) with conventional management ii) monoculture, full sun (in the cocoa production phase) with organic management iii) diversified, shaded agroforestry system with conventional management iv) diversified, shaded, agroforestry system with organic management v) diversified, shaded successional agroforestry system with no external inputs, and vi) fallow land (no crops) as a reference for biodiversity and soil fertility studies.
