Pengaruh Inokulasi Mikoriza Terhadap Pertumbuhan dan Produksi Beberapa Varietas Tanaman Sorgum (Sorghum bicolor (L.) Moench) pada Gawangan Tanaman Karet TBM I
ABSTRACT
RUDI PURNOMO: The Effect of mycorrhizae inoculation for growth and
production of some sorghum varieties under the immatured plants 1 of rubber
land. supervised by JONATAN GINTING and CHARLOQ.
This research was conducted to study effect of some dosage mycorrhrizae
inoculation for growth and production of some sorghum varieties under the
immatured plants 1 of rubber land. This research was conducted at Sungei Putih
Research Center, Galang district, Nort Sumatera Province from October 2014 –
January 2015, using group random design with varieties (numbu and kawali) and
Mycorrhizae inoculation (0 gram, 10 gram, 20 gram and 30 gram) with repeated
three times. Parameters observed were plant height, number of leaves, stem
diameter, flowering time, harvesting time, yield per plant, yield per plot and 1000
grains weight.
The result showed that varieties affected significantly for plant height,
stem diameter, flowering time, harvesting time, yield per plant, yield per plot and
1000 grains weight. Mycorrhizae inoculation affected significantly for plant
height, number of leaves, stem diameter, harvesting time, yield per plant and yield
per plot. There interaction between varieties and mycorrhizae inoculation did not
affected significantly for all parameters.

I, dibimbing oleh JONATAN GINTING dan CHARLOQ.
Penelitian ini dilakukan untuk mengetahuipengaruh beberapa dosis
inokulasi mikoriza terhadap pertumbuhan dan produksi beberapa varietas sorgum
pada gawangan tanaman karet TBM I.Penelitian dilaksanakan di Balai Penelitian
Sungai Putih, Kecamatan Galang, Sumatera Utara pada Oktober 2014 - Januari
2015, menggunakan rancangan acak kelompok dua faktor perlakuan yaitu
varietas (numbu dan kawali) dan inokulasi mikoriza (0 gram,10 gram, 20 gram,
dan 30 gram) dengan 3 ulangan. Parameter yang diamati adalah tinggi tanaman,
jumlah daun, diameter batang, umur berbunga, umur panen, produksi per
tanaman, produksi per plot dan bobot 1000 biji.
Hasil penelitian menunjukkan bahwa perlakuan varietas berpengaruh nyata
terhadap tinggi tanaman, diameter batang, umur berbunga, umur panen, produksi
per tanaman, produksi per plotdan bobot 1000 biji. Perlakuan inokulasi mikoriza
berpengaruh nyata terhadap tinggi tanaman, jumlah daun, diameter batang, umur
panen, produksi per tanaman dan produksi per plot. Interaksi keduanya
berpengaruh tidak nyata terhadap seluruh parameter amatan.
