Analisis Tumbuh Kenaf (Hibiscus Cannabicus L.) Dengan Pemberian Pupuk Hayati Dibawah Tegakan Kelapa Sawit
ABSTRACT
KHAIRUNNISA. Analysis plants growth of kenaf with biological
fertilizer under of oil palm. Supervised by CHAIRANI HANUM and ROSITA
SIPAYUNG.
The objective of research was to study effect of biological fertilizer under of 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, The design used was a randomized block design with two
factors. The first factor is a biological fertilizer (Without a biological fertilizer,
Mycoriza 5 g / plant and Azotobacter 10 cc / plant), the second factor is the shade
of the oil palm (open land and shade the of the oil palm). The results showed that
kenaf planted under shade of oil palm significantly affected the parameters plant
height, number of leaves, stem diameter, fresh weight of shoot, fresh weight of
roots, dry weight of shoot, root dry weight, total leaf area, the rate of plant growth,
leaf area index and net assimilation rate at 4 weeks after planting, whereas
treatment of biological fertilizer significant effect on root dry weight 12 week
after planting and the number of leaves of plants 4 and 6 week after planting,
There is no interaction between the two treatments on all parameters
Keywords: kenaf, shade, biological fertilizers

KHAIRUNNISA. Analisis tumbuh kenaf dengan pemberian pupuk hayati
dibawah tegakan kelapa sawit oleh CHAIRANI HANUM dan ROSITA
SIPAYUNG.
Penelitian ini bertujuan untuk mengetahui pertumbuhan kenaf dengan
pemberian pupuk hayati dibawah tegakan kelapa sawit. Penelitian dilaksanakan di
PTPN III Desa Silau Dunia, Kecamatan Galang Kabupaten Serdang Bedagai,
Sumatera Utara pada bulan Mei sampai September 2015. Rancangan yang
digunakan adalah rancangan acak kelompok dengan dua faktor. Faktor pertama
yaitu pupuk hayati (Tanpa pupuk hayati, Mikoriza 5 g/tanaman dan Azotobacter
10 cc/tanaman), faktor kedua yaitu naungan kelapa sawit (Lahan terbuka dan
dibawah naungan kelapa sawit menghasilkan). Hasil penelitian menunjukkan
bahwa kenaf yang ditanam dibawah naungan berpengaruh nyata terhadap
parameter tinggi tanaman, jumlah daun, diameter batang, bobot segar tajuk, bobot
segar akar, bobot kering tajuk, bobot kering akar, total luas daun, laju
pertumbuhan tanaman, indeks luas daun dan laju asimilasi bersih pada 4 MST,
sedangkan perlakuan pupuk hayati berpengaruh nyata pada parameter bobot
kering akar umur 12 MST dan jumlah daun tanaman umur 4 dan 6 MST, tidak ada
interaksi antara kedua perlakuan terhadap semua parameter.
Kata kunci: kenaf, naungan, pupuk hayati
