PENGARUH FREKUENSI PEMBERIAN DAN DOSIS PUPUK ORGANIK AIR TERHADAP PERTUMBUHAN DAN INDEKS MUTU BIBIT GAHARU (AQUILARIA MALACCENSIS LAMK) DI PERSEMAIAN
Abstract: Aquilaria
malaccensis Lamk is one of the agarwood-producing plants have high economic
value and low populations in the natural forest. Since 2004 CITES sets of this
type in Appendix II and the needed multiplication of the species. This study
aimed to obtain information about the frequency and dosage which was optimum
for the growth of seedlings of A. malaccensis. Giving of liquid organic
fertilizer is expected to increase the growth and Seedling Quality Index (SQI)
A. malaccensis. This research was conducted using a Completely Randomized
Design (CRD) with two factors, namely the frequency of fertilizer (a1: 10 days,
a2: 15 days and a3: 20 days) and dozis of fertilizers (b0: 0 cc / l of water,
b1: 2.5 cc / l of water, b2: 5 cc / l of water and b3: 7.5 cc / l of water).
Parameters measured were height, leaf number, diameter, fresh weight and dry
weight of seedlings. The results showed that the frequency and dosage of
fertilizers provide a good influence on the growth of seedlings of A.
malaccensis and same with the seed quality index. The frequency of the best
fertilizer is 10 days (a1) with a dose of fertilizer 2.5-5 cc / l of water (b1
and b2).
