ABSTRACT The study on the efficacy of glyphosate on the growth and yield of genetically modified corn varieties. The study aims to determine the efficacy of glyphosate on the growth and yield two varieties of genetically modified corn. The study was carried out at “Balai Benih Induk”, Tanjung Selamat, Medan from March to June 2012. Four treatments namely stacked genetically modified corn “X” x genetically modified corn “Y” (sprayed with glyphosate), genetically modified corn “X” (no glyphosate application, manual weeding), genetically modified corn “Y” (sprayed with glyphosate), hybrid DK979 (no glyphosate application, manual weeding). The result showed that glyphosate did not affect genetically modified corn. Keywords: glyphosate, varieties, corn, tolerant ABSTRAK Uji efikasi herbisida glifosat terhadap pertumbuhan dan produksi beberapa varietas jagung produk rekayasa genetika. Penelitian ini bertujuan untuk mengetahui efikasi herbisida glifosat terhadap pertumbuhan dan produksi dua varietas jagung produk rekayasa genetika. Penelitian dilaksanakan di Balai Benih Induk Tanaman Palawija, Tanjung Selamat, Medan pada bulan Maret sampai dengan Juni 2012. Empat perlakuan yaitu Jagung stacked PRG ”X” x PRG ”Y” (disemprot dengan glifosat), Jagung PRG ”X” (tanpa glifosat, disiang manual), Jagung PRG ”Y” (disemprot dengan glifosat), Jagung hibrida DK979 (tanpa glifosat, disiang manual). Hasil penelitian menunjukkan bahwa herbisida glifosat tidak berpengaruh nyata terhadap keracunan jagung produk rekayasa genetika. Kata kunci: glifosat, varietas, jagung, toleran herbisida.

Penelitian ini bertujuan untuk mengetahui pengaruh pemberian vermikompos dan pupuk P terhadap pertumbuhan tanaman kedelai. Penelitian ini dilaksanakan di lahan percobaan Fakultas Pertanian USU (± 25 m dpl) pada Maret – Juni 2015 menggunakan Rancangan Acak Kelompok faktorial 2 faktor yaitu pemberian vermikompos (0, 0,25, 0,5 dan 0,75 kg/polibag) dan pemberian pupuk P (0, 0,625, 1,25 dan 1,825 g/polibag). Parameter yang diamati antara lain tinggi tanaman (cm), diameter batang (mm), umur berbunga (hari), bobot basah akar (g), bobot kering akar (g), bobot basah tajuk (g), bobot kering tajuk (g), volume akar (ml), jumlah cabang produktif, jumlah polong per tanaman, jumlah polong berisi, bobot 100 biji kering (g) dan umur panen (hari). Hasil penelitian menunjukkan bahwa pemberian vermikompos dan pupuk P berpengaruh nyata terhadap semua parameter kecuali umur panen (hari) dan bobot 100 biji kering. Interaksi antara vermikompos dan pupuk P berpengaruh nyata terhadap umur berbunga tanaman kedelai. Hasil yang terbaik diperoleh pada dosis vermikompos 0,75 kg/polibag dan pupuk P 0,625 g/polibag.Kata kunci : vermikompos, Pupuk P, kedelai

The research was carried out at public land Desa Namo Gajah, Kecamatan Medan Tuntungan(±25 m dpl) on April to November 2015. The research used factorial Randomized Block Design (RBD) with two factors and three replications.The first factor was sweet potato varietieswith 3 kinds (Antin-1; Beta-1; and Sari)and the second factorwas rice straw compost with 4 levels(0; 5; 10; and 15 ton/ha). Data were analized with Analysis of Variance and continued with Duncan’s Multiple Range Test (DMRT). The variables observed weight biomass of plant, tuber weight per plot, and harvest index. The result of research showed that the best interaction of sweet potato varieties and rice straw compost was combination of Sari and rice straw compost 2 kg on weight biomass, tuber weight per plot, and harvest index.

The experiment was conducted in Desa Pasar Kawat District of Beringin Kabupaten DeliSerdang on Juny to November 2015, using a factorial randomized block design with two factors, the first factor is varieties (Antin 1, Antin 2, Antin 3) and the second factor is doses Bokashi (0, 5, 10, 15 ton/ha).Data were analized with Analysis of Variance and continued with Duncan’s Multiple Range Test (DMRT). Observed were increase height of plant, weight tuber per plot and index of yield.The results showed that application of varieties increased weight tuber per plot, index of yield.Doses Bokashi increasing the height of plant,weight tuber per plot.Interaction of varieties and giving multiple doses bokashi source were significantly effect to average weight tuber.
