PEMANFAATAN RHIZOBIUM UNTUK MENINGKATKAN PERTUMBUHAN SEMAI SENGON (Paraserianthes falcataria) PADA MEDIA TANAH BEKAS TAMBANG SEMEN
Abstract: Ex-mining land use
of cement was an alternative medium or planting medium, but this alternative
was to meet the constraints of low soil fertility levels. Therefore, one way
that could be attempted is creating suppressive soil in the form of applying
biofertilizer such as rhizobium (Nitrogen Fixing Bakteria). Research methods
used a complete randomized design. The first factor was the type of Rhizobium
(control, Shinorhizobium sp (S8.4), Rhizobium sp (S10.3.1) which was inoculated
on the plant Paraserianthes falcataria. Planting medium used was sterilized
soil from ex-cement mining land. The results of rhizobium inoculation on plants
showed different effectiveness in enhancing the growth of seedlings. Duncan
test results of the influence of a single factor BFN showed Shinorhizobium sp
(S8.4) could be associated with P. falcataria, to improved seedling growth and
able to gave growth response better when compared with treatment of Rhizobium
sp (S10.3.1) and control at variable observations on seedling diameters (1.65
mm), number of leaves (10.9 pieces), N absorption (2.10 g/plant) and P
absorption (0.16 g/plant).
