ABSTRACT
Application of forestry biotechnology in the field of
microorganism utilization is very necessary in dealing
with the condition of marginal land. This effort is needed in increasing seedling growth rate in the field and improving soil condition. The presence of VA Mycorrhiza and
Rhizobium on the growth of Forestry plant is very important in marginal land.
The main objective of this research was to test of
inoculation effect of VA Mycorrhiza and Rhizobium on the
growth of Acacia mangium, Paraserianthes falcataria in
nursery.
A. mangium,,andP. falcataria seedlings were inoculation with VA Mycorrhiza and Rhizobium. The VA Mycorrhiza
fungi which were used Gigaspora margarita and Glomus
etunicatum, whereas for bacteria of Rhizobium were NA
1533, NA 8 8 1 7 , NA 8 8 1 8 , NA 8 8 7 8 on A. mangium and 1, PFWT
2 on P. Falcataria. As an additional treatment were
giving of TSP fertilizer and wiehout fertilization.
The research was. designed in spl-it-split plot with
completely random design. As main plot was Rhizobium, sub
plot was VA Mycorrhiza and fertilization as sub-sub plot.
The variables on responds which were "measured, height,
diameter, biomass, number of root nodule and percentage of
mycorrhiza infection.
Research result indicates that the best isolate of
Rhizobium and VA mycorrhiza for A. mangium are NA 8 8 7 8 ,
and G . margarita. The best treatment is combination of NA
