WIKA SIMANJUNTAK:ResponsPertumbuhandan Hasil Sorgum
(Sorghum
bicolor(L.) Moench) Terhadap Jarak Tanam dan Waktu Penyiangan Gulma.
Dibimbing oleh EDISON PURBA dan T. IRMANSYAH.
Tujuan penelitian untuk melihat respons pertumbuhan dan hasil sorgum
(Sorghum bicolor (L.) Moench) terhadap jarak tanam dan waktu penyiangan
gulma.Penelitian dilaksanakan di Jl. Tri Darma Fakultas Pertanian Universitas
Sumatera Utara, Medan dengan ketinggian25 meter di atas permukaan laut mulai
dari bulan Desember2014 hingga April 2015, menggunakan rancangan petak
terbagi dengan dua faktor yaitu jarak tanam (70x30, 70x20, 70x10) dan waktu
penyiangan gulma (tanpa penyiangan, disiangi 2 MST, disiangi 4 MST, disiangi 6
MST, disiangi 8 MST, bebas gulma).
Parameter yang diamati tinggi tanaman, jumlah daun, diameter batang,
umur berbunga, berat basah malai per sampel, berat basah malai per plot, produksi
biji per sampel, produksi biji per plot, bobot 1000 biji. Hasil penelitian
menunjukkan perlakuan jarak tanam berpengaruh nyata terhadap tinggi tanaman
pada umur 6 dan 8 MST berat basah malai per sampel. Waktu penyiangan gulma
berpengaruh nyata pada tinggi tanaman 6 dan 8 MST, jumlah daun umur 4, 6 dan
8 MST, diameter batang 4,5,6,7 dan 8 MST, berat basah malai per sampel, berat
basah malai per plot, produksi biji per sampel, produksi biji per plot, dan bobot
1000 biji.
Kata Kunci: Jarak Tanam, Waktu Penyiangan Gulma, Sorgum

sorghum (Sorghum bicolor (L.) Moench) with spacing and weeding time.
Supervised by EDISON PURBA and T. IRMANSYAH.
The aim of this research was to observe the response growth and result
sorghum (Sorghum bicolor (L.) Moench) with spacing and weeding time. This
research was conducted at Jl. Tri Darma Fakultas Pertanian Universitas
Sumatera Utara, Medanwith altitude 25meter above sea level with 2 factor
namely spacing (70x30, 70x20, 70x10) and weeding time (without weeding, 2
weeks after planting, 4 weeks after planting, 6 weeks after planting, 8 weeks after
planting, clean weeding).
Observed paramaters were plant height, number of leaves, diameter of
stem, days of flowering, wet weight of tassel per sample, wet weight of tessel per
plot, sample seed production, plot seed production, weight of 1000 seed. This
research showed the treatment of spacing had a significant effect against height of
plant at 6 and 8 week after plant and wet weight of tassel per sample.Weeding
time had a significant effect against plant height 6 and 8 after planting, number of
leaves 4 6 and 8 after planting, diameter of stem 4, 5, 6, 7 and 8 weeks after
planting, days of flowering, wet weight of tassel per sample, wet weight of tessel
per plot, sample seed production, plot seed production, weight of 1000 seed.
