The role of shade tree pruning in cocoa agroforestry systems: agronomic and economic benefits

Abstract Cocoa-based agroforests are promoted to replace monocultures for the provision of ecosystem services. However, shade tree pruning, an important tool sustain cocoa yields, is not commonly implemented. This study investigates effect pruning on both agronomic and economic performance. In Bolivia, four famers’ sites were divided in half, trees pruned one two plots. Pruning resulted a significant increase yield, from average 430 710 kg ha ?1 by boosting flowering pod production, but reducing proportion damaged pods, those lost cherelle wilt. Additionally, scenario calculations using international organic premium prices conducted evaluate feasibility pruning. The minimum, mean maximum yield 22 local cocoa-based agroforestry farms used as reference 25, 50 75% scenarios. Offsetting costs highly depended initial levels. Using minimum all scenarios led lower net income compared with no For level, was equal that obtained without when above 51%. At higher income. Our results prove importance yields. current farm-gate cocoa, farmers alone cannot cover extra management costs. sector should discuss different strategies support broader adoption agroforests.
