ABSTRACT

Species trial of native fast growing tree species were carried out at Trat agroforestry
research and training station, Mueang district, Tr at province. The objectives of the study were
to assess growth performances and biomass production of native fast growing tree species and to
select suitable tree species for planting at the site by using Randomized Complete Block Design
(RCBD) with four tree species, four replications, thirty six trees/treatment and 2 m x 2 m spacing.
The results showed that survival and growth rate of 4 species were highly significant
differences. Survival percentage of Anthocephalus chinensis Rich. Ex Walp, Pterocymbium
javanicum R.Br. and Artocarpus rididus Blume. were 16.67%, 63.20% and 63.89%, respectively.
Means of diameter at breast height (DBH) were 17.47, 9.80 and 9.46 cm., respectively. Mean of
total height (H) of those were 16.23, 10.86 and 9.67 m., respectively. Means of annual increment
-1
of DBH of those were 2.18, 1.23 and 1.18 cm.yr , respectively. Means of annual increment of
1
height of those were 2.03, 1.36 and 1.21 m.yr , respectively. For total above ground biomass of
-1
those were 8.25, 6.75 and 4.41 ton.rai , respectively. Means of annual increment of total above
-1
-1
biomass of those were 1.03, 0.85 and 0.55 ton.rai .yr , respectively. However, those native fast
growing tree species had lower survival rate and growth rate than Acacia mangium willd.
Hence, the results of the study, could conclude that suitable tree species for planting at
the site were A. chinensis because they showed better growth and biomass production than other
native fast growing tree species. Higher survival percentage of A. chinensis should be promoted.
