Assessing the Growth of Local Sengon and Solomon Sengon in Agroforestry System

Abstract

Development of timber industry and demand for wood in Indonesia must be balanced with an enhancement of timber production. Utilization of fast growing species such as sengon (Falcataria moluccana) may be done to increase the timber production. The optimal use of the land will be achieved by applying agroforestry system. This research aims to compare the growth between local sengon and solomon sengon in agroforestry system. The research showed that provenance is significantly influence the diameter. The interaction between provenance and planting technique do not affect the height, diameter, canopy area, depth of rooting system, root lenght, and root diameter horizontally. Solomon sengon F1 with opened polybag treatment revealed the highest average in diameter. The best average of depth and root diameter was found in closed polybag treatment, whereas the best average of root lenght was found in opened polybag treatment.
