EFEKTIVITAS TRICHODERMA DAN PUPUK KANDANG TERHADAP PERTUMBUHAN TINGGI DAN DIAMETER SEMAI ACACIA MANGIUM PADA TANAH ULTISOL
Abstract: This research aimed
to obtain a dose of Trichoderma sp. and manure that effective on the growth of Acacia
seedlings in Ultisol soil. The research design was a Factorial Complete Random
Designthat is consisting of 2 (two) factors which are dose of Trichoderma sp.
and dose of cow manure.Dosage of Trichoderma sp. consisting of: 0 gr/polybag
(T0), 5 gr/polybag (T1), 10 gr/polybag (T2),and 15 gr/polybag (T3). Dosage of
cow manure consisting of: 0 gr/polybag (K0), 50 gr/polybag(K1), 100 gr/polybag
(K2), and 150 gr/polybag (K3). Each treatment was repeated 3 (three) timesso
that the total amount of treatment was 48 seedlings. The parameters observed
were the heightand diameter of the seedlings carried out for 2 (two) months at
the Silviculture Laboratory of Forestry Faculty, Tanjungpura University. The
result showed the dose of Trichoderma sp., manureand its interaction had no
significant effect on the growth of seedlings height. Dose of Trichodermasp.
was very significant effect on the growth of seedlings diameter, while manure
and its interactionhave no real effect. The best dose for seedlings diameter
growth is T3K2 treatment (dosage 45 gram Trichoderma sp. and 100-gram cow
manure).
