Pertumbuhan Beberapa Varietas Kenaf (Hibiscus cannabinus L.) Dengan Pemberian Kompos Tandan Kosong Kelapa Sawit (TKKS) Di Bawah Tegakan Kelapa Sawit
ABSTRACT
JOSAFAT PASARIBU. Growth of some varieties of kenaf with
composting under oil palm empty fruit bunches of oil palm. Supervised by
CHAIRANI HANUM and RATNA ROSANTY LAHAY.
The objective of research to determine the growth varieties of kenaf with
composts bunches oil palm. The research has been conducted at PT. Perkebunan
Nusantara III silau dunia village, district galang serdang bedagai, north sumatera
from may to september 2015, using a randomized block design with two factors.
The first factor is varieties kenaf (KR 11, KR 12 and KR 14) the second factor is
with composts bunches oil palm (0, 50, 100 and 150 g/ plant) The results showed
that treatment of several varieties of kenaf under stands of oil palm (shade)
significantly affect root dry weight, while treatment compost empty fruit bunches
of oil palm real effect on the parameters plant height, number of leaves, stem
diameter, as well as the interaction of both real effect on the amount of leaf age
11-12 period after planting and plant stem diameter ages 4-9 times after planting.

JOSAFAT PASARIBU. Pertumbuhan beberapa varietas kenaf dengan
pemberian kompos tandan kosong kelapa sawit dibawah tegakan kelapa sawit
oleh CHAIRANI HANUM dan RATNA ROSANTY LAHAY.
Penelitian ini bertujuan untuk mengetahui pertumbuhan varietas kenaf
dengan pemberian kompos tandan kelapa sawit. Penelitian dilaksanakan di PTPN
III Desa Silau Dunia, Kecamatan Galang Kabupaten Serdang Bedagai, Sumatera
Utara pada bulan Mei sampai September 2015, menggunakan rancangan acak
kelompok dengan dua faktor. Faktor pertama yaitu varietas (KR 11, KR 12 dan
KR 14), faktor kedua yaitu kompos tandan kelapa sawit (0, 50, 100 dan 150
g/tanaman). Hasil penelitian menunjukkan bahwa perlakuan beberapa varietas
kenaf dibawah tegakan kelapa sawit (naungan) berpengaruh nyata terhadap bobot
kering akar, sedangkan perlakuan kompos tandan kosong kelapa sawit
berpengaruh nyata pada parameter
tinggi tanaman, jumlah daun, diameter
batang,serta interaksi kedua berpengaruh nyata pada jumlah daun umur 11-12
MST dan diameter batang tanaman umur 4 – 9 MST.
