Respons Pertumbuhan dan Produksi Dua Varietas Sorgum (Sorghum bicolor (L.) Moench) Terhadap Mulsa Organik di Lahan Sawah
ABSTRACT
IVAN MANONGGOTUA UJUNG: Response of growth and production of two
varieties sorghum (Sorghum bicolor(L.) Moench) with various of organic
mulching in paddy soil. Supervised by LISA MAWARNI and T. IRMANSYAH
This research examined the influence of organic mulching and its
interaction with two varieties of sorghum (Sorghum bicolor (L.) Moench) growth
and production. This research was conducted at Jl. Setiabudi Psr V, Sub District
Tanjung Sari, Medan with altitude 25 meter above sea level with 2 factor namely
varieties (Kawali, Numbu) and various of organic mulch (without mulch, hay
mulch, grass mulch). Observed paramaterers were plant height, number of leaves,
days of flowering, harvesting time, weight of seed per tassel per sample, weight of
seed per tessel per plot, sample production, plot production, weight of 1000 seed.
This research showed the treatment of varieties had a significant effect against
height of plant at 7,8 and 9 week after plant, weight of seed per sample,
production per sample, weight of 1000 seed. Kind of organic mulch had a
significant effect against number of leaves at 8 and 9 week after plant, weight of
1000 seed. This research showed the interaction between varieties and kind of
mulch had asignificant effect with height of plant at 4-9 week after plant, number
of leaves at 8 and 9 week after plant, weight of seed per tassel per sample, plot
production, production per sample, weight of 1000 seed and harvesting time.

Lahan Sawah. Dibimbing oleh LISA MAWARNI dan T. IRMANSYAH.
Tujuan penelitian untuk melihat respons pertumbuhan dan produksi dua
varietas sorgum (Sorghum bicolor (L.) Moench) terhadap mulsa organik di lahan
sawah. Penelitian dilaksanakan di Jl. Setia Budi Pasar 5, kelurahan Tanjung Sari,
Medan dengan ketinggian 25 meter di atas permukaan laut mulai dari bulan Juli
hingga November 2014, menggunakan rancangan acak kelompok dengan dua
faktor yaitu varietas (kawali, numbu) dan mulsa organik (tanpa mulsa, mulsa
jerami, mulsa alang- alang). Parameter yang diamati tinggi tanaman, jumlah daun,
umur berbunga, umur panen, berat biji malai per sampel, berat biji malai per plot,
produksi per sampel, produksi per plot, bobot 1000 biji. Hasil penelitian
menunjukkan perlakuan varietas berpengaruh nyata terhadap tinggi tanaman pada
umur 7, 8 dan 9 MST, berat biji malai per sampel, produksi per sampel, bobot
1000 biji. mulsa organik berpengaruh nyata pada jumlah daun umur 8 dan 9 MST,
bobot 1000 biji. Hasil penelitian menunjukkan interaksi antara varietas dengan
mulsa berpengaruh nyata terhadap tinggi tanaman umur 4-9 MST, jumlah daun
umur 8 dan 9 MST, berat biji malai per sampel, produksi per plot, produksi per
sampel, bobot 1000 biji, umur panen.
