PENGARUH BERBAGAI DOSIS PUPUK ORGANIK CAIR URIN SAPI TERHADAP PERTUMBUHAN SEMAI JABON MERAH (Anthocephalus macrophyllus (Roxb.) Havil)
Abstract: Jabon Red
(Anthocephalus macrophyllus Roxb.) Havil.) is a timber species that is
currently intensively planted by people of Indonesia because it has a rapid
growth and multi-function. The aim of this study was to determine the effect of
various doses of liquid organic fertilizer of cow urine on the growth of Jabon
Red seedlings (Anthocephalus macrophyllus Roxb) Havil). The experiment was
conducted at the Green House and Forestry Science Laboratory, Forestry Faculty,
Tadulako University, on March to May 2014. This study employed a completely
randomized design (CRD), which consists of five levels of treatment, they are
M0 = 0 ml / liter of water (control) M1 = 150 ml / liter of water, M2 = 250 ml
/ liter of water, the M3 = 350 ml / liter of water, M4 = 450 ml / liter of
water. On these five treatments, they were replicated in each of four
replications, so that, the total seedlings required were 20 samples. Observed
variables are the increase of plant height, leaf number, diameter, fresh weight
and dry weight of Jabon seedling. To find out the difference between
treatments, then, it was tested Honestly Significant Difference (HSD). The
results of this study addressed that dosing of liquid organic fertilizer of cow
urine, having an extremely significant effects on seedling growth of Jabon Red
(Anthocephalus macrophyllus Roxb) Havil. This was evidenced by the increase in
plant height, leaf number, diameter, fresh weight and dry weight of Jabon
seedling compared to jabon seedling without fertilizer. Dosing 150ml / l of
water gives better Jabon seedling growth, of all treatments were tested with an
average of 6.38 cm increase in plant height, number of leaves strands was 6.50,
diameter of trunk was 1.65 mm, fresh weight of shoots was 5.56 grams and dry
weight of shoots was 0.55 grams.
