This study aims to obtain the silica fertilizer dosage and application time for growth and production sorghum (Sorghum bicolor (L) Moench.). This research was conducted at Faculty of Agriculture Universitas Sumatera Utara began from March until August 2018, This research used factorial randomized block design with two factors. The first factor was silica fertilizer dosage with four levels are 0 , 0.5, 1, and 1.5 gram/plot and the second factor was application time with four application time are: 10, 20, 30, and 40 Day After Planting. Parameter observed were plant's length, stem diameter, weight of 1000 seeds, weight of seed per sample and weight of seed per plot. Silica fertilizer and application time can improve growth and production of sorgum variety Super 2. The highest production percentage of sorgum reach 55.27% compared with control, the production reach 4.30 tons/hectare.
Penelitian ini bertujuan untuk mendapatkan dosis dan waktu aplikasi pupuk silika terbaik untuk pertumbuhan dan produksi sorgum (Sorghum bicolor (L) Moench.). Penelitian ini dilaksanakan di lahan Fakultas Pertanian Universitas Sumatera Utara pada bulan Maret sampai Agustus 2018, menggunakan Rancangan Acak Kelompok dengan 2 faktor perlakuan. Faktor pertama adalah dosis pupuk silika dengan 4 taraf perlakuan yaitu: 0, 0.5, 1, dan 1.5 gram/plot dan faktor kedua yaitu waktu aplikasi dengan 4 waktu pemberian yaitu: 10, 20, 30, 40 HST. Parameter yang diamati adalah panjang tanaman, diameter batang, bobot 1000 biji, bobot biji/tanaman, dan bobot biji/plot. Pemberian pupuk silika dan waktu aplikasi dapat meningkatkan pertumbuhan dan produksi sorgum varietas Super 2. Persentase produksi sorgum tertinggi mencapai 55.27% dibandingkan dengan kontrol dengan hasil produksi yang dicapai adalah 4.30 ton/ha.
