A comparison of agrisilvicultural systems with plantation forestry in the Atlantic lowlands of Costa Rica, 1: Tree survival and growth
Survival and growth data (ages 0-5 years) are presented for two timber species (Acacia mangium, Cordia alliodora) planted in monocultures or in association with a sequence of agricultural crops Zea mays, Zingiber officinale and Eugenia stipitata (a fruit shrub) in the tropical humid Caribbean lowlands of Costa Rica. Average annual height and diameter growth rates were 3.2 m and 4.0 cm (C. alliodora), 3.5 m and 3.8 cm (A. mangium). C. alliodora associated with crops gave the greatest productivity with an average total stem volume increment of 19 m3 ha exponent -1 yr exponent -1. Root rot of A. mangium (aminly Rosellinia sp.), leading to tree mortality, was greater in pure plots compared to associated plots. A. mangium can not be recommended for similar sites because of this problem.
