The LTE was established on land which was under fallow for 20 years, covered with a secondary forest.
Design period: (2008—)
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.
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.
