ABSTRACT

The mitigation of CO₂ emission through high-productivity systems associated with restoration of degraded sites have been increasingly common, highlighting the importance of estimates of the amount and distribution of plant biomass in different ecosystems and under different management systems. The aim of this study was to investigate the influence of planting and soil characteristics and the type of management performed over the aboveground biomass accumulation in two reforestation projects with native species, implanted through Taungya agroforestry system. The differences in aboveground biomass accumulation were probably influenced by agroforestry management, since these variations showed to be independent of age (considered within the age range in this study), the spacing, the species composition, and soil fertility. The values of aboveground biomass are similar to those reported in the literature for other reforestation projects with native species of similar ages.

	R1 (2004)	R2 (2006)
Talhão 1	Cidinho (18 months) - Planted Castor beans together with maize and, after harvest, planted cassavas.	Zulmira - Planted maize. After the harvest planted common beans.
Talhão 2	Betão (6 months) - Planted maize. After the harvest followed with weed control in the reforestation, but give up with further crops.	Afonso - Planted maize. After the harvest planted common beans.
Talhão 3	Adão (12 meses) - Planted cassavas together with maize.	Pacheco - Planted maize, common beans, pumpkins, okra and maxixe, in random blocks.
Talhão 4	Cícero (36 months) - Planted cassavas once.	Zé Buriti - Planted maize. After the harvest planted common beans.
