Abstrak. Penelitian ini bertujuan untuk mengetahui pengaruh dosis pupuk vermikompos dan pupuk organik cair Agrobost yang tepat serta interaksi keduanya terhadap pertumbuhan dan hasil jagung manis. Penelitian ini dilaksanakan di Kebun Percobaan dan Laboratorium Ilmu Benih Fakultas Pertanian, Universitas Syiah Kuala, Darussalam, Banda Aceh pada bulan Juli sampai dengan Oktober 2021. Penelitian ini menggunakan Rancangan Acak Kelompok pola faktorial dengan 2 faktor dan 3 ulangan. Faktor yang diteliti yaitu dosis vermikompos terdiri dari 4 taraf yaitu 0, 2,5, 5 dan 7,5 ton ha-1 dan konsentrasi pupuk organik cair Agrobost yang terdiri dari 3 taraf yaitu 0, 15 dan 30 ml L-1. Data yang diperoleh dianalisis dengan menggunakan uji F, dilanjutkan dengan uji BNJ pada taraf 5%. Hasil penelitian menunjukkan bahwa dosis pupuk vermikompos berpengaruh sangat nyata terhadap tinggi tanaman 15 HST dan 30 HST dan diameter pangkal batang 15 HST dan 45 HST dan berpengaruh tidak nyata terhadap tinggi tanaman 45 HST, diameter pangkal batang 30 HST, berat berangkasan basah, berat berangkasan kering, berat tongkol berkelobot, berat tongkol tanpa kelobot, diameter tongkol, panjang tongkol dan potensi hasil dengan dosis terbaik dijumpai pada dosis V3 yaitu 7,5 ton ha-1. Konsentrasi pupuk organik cair Agrobost berpengaruh tidak nyata terhadap tinggi tanaman 15, 30, 45 HST, diameter pangkal batang 15, 30, 45 HST, berat berangkasan basah, berat berangkasan kering, berat tongkol berkelobot, berat tongkol tanpa kelobot, diameter tongkol, panjang tongkol dan potensi hasil dengan konsentrasi cenderung terbaik dijumpai pada perlakuan A1 yaitu 15 ml L-1. Tidak terdapat interaksi antara dosis pupuk vermikompos dan konsentrasi pupuk organik cair Agrobost terhadap semua parameter yang diamati.

Abstract. This study aims to determine the effect of the right dose of vermicompost and Agrobost liquid organic fertilizer and their interaction on the growth and yield of sweet corn. This research was conducted at the Experimental Garden and Laboratory of Seed Science, Faculty of Agriculture, Syiah Kuala University, Darussalam, Banda Aceh from July to October 2021. This study used a factorial randomized block design with 2 factors and 3 replications. The factors studied were the dose of vermicompost consisting of 4 levels, namely 0, 2.5, 5 and 7.5 tons ha-1 and the concentration of liquid organic fertilizer Agrobost which consisted of 3 levels, namely 0, 15 and 30 ml L-1. The data obtained were analyzed using the F test, followed by the BNJ test at the 5% level. The results showed that the dose of vermicompost fertilizer had a very significant effect on plant height 15 DAP and 30 DAP and stem diameter at 15 DAP and 45 DAP and had no significant effect on plant height 45 DAP, stem diameter 30 DAP, weight of wet root and dry weight. , weight of cob with cob, weight of cob without cob, diameter of ear, length of cob and yield potential with the best dose found at dose V3 which is 7.5 tons ha-1. The concentration of liquid organic fertilizer Agrobost had no significant effect on plant height 15, 30, 45 DAP, diameter of stem base 15, 30, 45 DAP, weight of wet root, weight of dry root, weight of cob with cob, weight of cob without husk, diameter of ear, length of cob. and the yield potential with the best concentration tended to be found in treatment A1 which was 15 ml L-1. There was no interaction between the dose of vermicompost fertilizer and the concentration of liquid organic fertilizer Agrobost on all parameters observed.
