APLIKASI BEBERAPA DOSIS ABU SERBUK GERGAJI DAN PUPUK HIJAU JENIS LEGUMINOCEAE TERFORMULASI SEBAGAI PEMACU PERTUMBUHAN SEMAI Eucalyptus pellita F. MUELL PADA MEDIUM GAMBUT
Abstract: Eucalyptus pellita
is one of plants that was developved as industrial timber plantations (ITP) and
has entered third rotations in Riau. Overlay peat medium is handicap ITP
business in Riau. Therefore it is urgent to determine treatment for the
improvement of the peat medium. This research aims to determine influence of
ash saw dust and green fertilizer type leguminoceae formulated to Eucalyptus
pellita seedlings in peat medium and the best dosage to growth of Eucalyptus
pellita seedlings. Research using randomized complete design (RCD) consist of
five treatments and four replications and five units trial. T0 = No provision
of ash saw dust and green fertilizer
type leguminoceae formulated ; T1 = 125 gr/polybag, T2 = 225 gr/polybag, T3 =
325 gr/polybag,and T4 = 425 gr/polybag. Research proved that the aplication in
peat medium can increase the quality of Eucalyptus pellita seedlings. The
aplication with a dosages 425 gr/polybag in peat medium is the best
treatment to percent of live (100,00%),
the height growth (23,44 cm) and top root/ratio (2,00).
