Abstract
In Misiones, in the northeast of Argentina, agroforestry systems of timber trees and perennial cash crops are becoming increasingly common. We evaluated the productivity of Ilex paraguariensis St Hill (South American holly or yerba mate, Aquifoliaceae) in association with indigenous trees: Enterolobium contortisiliquum (Vellozo) Morong. (timbo, Leguminosae, a N2-fixing tree), and two timber species, Balfourodendron riedelianum (Engler) Engler (guatambu, Rutaceae) and Tabebuia heptaphylla (Vellozo) Toledo (lapacho negro, Bignoniaceae). Five years after planting, the tree species were 2.7 to 5.0 m high and 3 to 7 cm in diameter at breast height, and the yerba mate produced its first harvest. Additionally, the production of associated crops of subsistence covered the annual needs of the farmer. These systems are promising for sustainable use of deforested lands in the region.
