Resumo
"Pequizeiro" (Caryocar brasiliense Camb.) is a species with great economic potential in the Brazilian savannah (cerra-do). The objective of this study was to characterize 20 cerrado areas with natural high density of pequizeiros in the southeast of Goiás, which area comprise 1 ha. The study showed that the "pequizeiro" is present in soils which would be considered of low fertility for most cultivated crops. A larger amount of this species is present in Inceptisol and Entisol than in Oxisol. Tree density is positively correlated with P and Zn soil content and total CTC. Average basal tree area is positively correlated to K and base saturation, and negatively correlated to H+Al and total CTC. Average height and yield are positively correlated to soil potassium content and base saturation. Fruit yield per plant is low and is directly related to tree height and canopy diameter. The number of trees with fruit is larger than that of trees without fruit in those trees with a diameter larger than 10 cm. This ratio increased as the diameter increased.
