Merbau darat (Intsia palembanica) merupakan tumbuhan hutan yang memiliki
kayu dengan kelas awet I, II dan kelas kuat I, II. Kayu ini dikenal memiliki serat
yang lurus, dapat dijadikan bahan kayu lapis, panel, meubel, ukiran, alat-alat
musik dan permukaan kayu mengkilap indah. Beberapa faktor yang
mempengaruhi pertumbuhan tanaman adalah naungan dan unsur hara. Penelitian
ini bertujuan untuk mengetahui pengaruh pemberian naungan dan pupuk terhadap
pertumbuhan bibit merbau darat. Penelitian ini disusun dalam rancangan acak
kelompok (RAK) dengan 4 kelompok dan 3 perlakuan. Kelompok pada
penelitian ini adalah intensitas naungan 0\%, 55\%, 65\%, dan 75\%, sedangkan
perlakuan dalam penelitian ini adalah pemberian pupuk majemuk NPK dengan
konsentrasi 0 g (kontrol), 2 g/polybag, dan 4 g/polybag. Besarnya satuan
percobaan yang digunakan sebanyak 1 bibit. Variabel pengamatan adalah
pertambahan tinggi, pertambahan diameter, panjang akar, jumlah daun, nisbah
tajuk dan akar, berat kering pucuk, berat kering akar, berat kering total dan indeks
ii
mutu bibit. Setelah data homogen, dilakukan analisis sidik ragam. Analisis
lanjutan dilakukan dengan uji beda nyata terkecil. Seluruh pengujian dilakukan
pada taraf nyata 5\%. Hasil penelitian menunjukkan bahwa pemberian naungan
55\% meningkatkan berat kering pucuk bibit merbau darat, tetapi pemberian
naungan diatas 65\% atau lebih justru menurunkan berat kering pucuk dan berat
kering total bibit. Sementara pemberian pupuk majemuk NPK dengan dosis 4
g/polybag memberikan pengaruh terbaik terhadap jumlah daun, nisbah tajuk akar,
berat kering pucuk dan berat kering total bibit merbau darat.
Kata kunci : merbau darat, naungan, pupuk.
ABSTRAK INGGRIS
Mirabow (Intsia palembanica) is one of high quality tropical wood. The wood of
mirabow is categorized in durable class I, II and strong class I, II. Mirabow has
the straight wood fiber, can be used as plywood, panels, furniture, musical
instrument and beautiful shiny wood surface. Among the factors that affect plant
growth were shading intensity and nutrients. The purpose of the research were to
figure out the effect of shading intensity and fertilization to the growth of
mirabow. The Block Randomized Design (BRD) of 4 groups and 3 treatment was
employed as research design. Group of the reseach was the provision of no
shading (0\%), shading intensity 55\%, shading intensity 65\%, and shading
intensity 75\%, meanwhile the dose of NPK fertilizer of 0 g/polybag, 2 g/polybag,
and 4 g/polybag were employed as the treatments. The large of experimental unit
were used 1 seedling. The variable that was observed were high accretion,
diameter accretion, root length, number of leaves, crown root ratio, dry weight of
crown, dry weight of root, total dry weight and quality index of seedling. Bartlett
test was employed to figure out the homogenity of datas. Then, analysis of
iv
variance was used to the least significant difference. The entire data tested on 5\%
significant level. The results showed that 55\% shading intensity, obviously
increase the dry weight of crown, however the shading intensity more than 65\% in
fact, evidently decrease the dry weight crown and total dry weight of mirabow
seedling. The dose of 4 g/polybag of NPK fertilizer, evidently the number of
leaves, crown root ratio, dry weight of crown and total dry weight of mirabow
seedling.
Keywords : mirabow, seed fertilisation, shading intensity.}
