Benefits and costs of intercropping reforestation in the Atlantic lowlands of Costa Rica.

Agroforestry options as a means of promoting reforestation were tested by establishing with 10 farmers simple comparisons between pure plantations and timber trees with annual or perennial intercrops. Two year-old intercropped trees on-farm had 22–48% greater height and 24–38% greater diameter than trees in pure plantations. The exception was Cordia alliodora that did not respond significantly to intercropping with cassava (Manihot esculenta). Only intercrops with the most valuable crops on agricultural soils produced a return to labour above the daily wage rate. On non-agricultural soils, farmers only intercrop a small area of their plantations with subsistence crops to meet home consumption needs. In the context of Costa Rica intercropping appeared to have a limited potential to finance the reforestation costs of farmers.
