Abstract

Initial development of tree species in crop-livestock-forest integration.

Abstract

The trees may improve the productivity of an agroecosystem, influencing the characteristics of soil, microclimate, hydrology and biological components associated. However, there is little information on the tree species most suitable for use in the system of integration crop-livestock-forest (SiLPF). In this context, the objective of this work was to evaluate the initial growth and survival of tree species native and exotic in different space arrangements and plant density in SiLPF in Planaltina, DF. The planting of seedling trees was conducted between January and March 2009. O design of treatments was randomized blocks with three replications of five treatments: control (tillage/grazing), native (two rows of trees and spacing between alleys of 12 m), Eucalyptus cloeziana (7 rows of trees and spacing between alleys of 22 m), Eucalyptus urograndis (2 rows of trees and spacing between alleys of 12 m) and Eucalyptus urograndis (2 rows of trees and spacing between alleys of 22 m). Among the alleys of forest species was planted sorghum in March 2009 and soybeans in December 2009 in no-tillage system with recommended fertilizer for the crop. There was no significant difference in survival between the treatments. Among the species studied native cedar species was less growth in height, while the guapuruvu, angico red mahogany and had the highest growth. Guanandi registered the worst performance and is not recommended in areas with high water deficit.
