Penelitian bertujuan untuk mengkaji pengaruh pemberian pupuk organik cair dengan konsentrasi yang berbeda serta menentukan konsentrasi pupuk yang paling optimal terhadap produksi bahan kering dan bahan organik sorgum hidroponik. Materi penelitian menggunakan benih sorgum (Sorghum bicolor) varietas Numbu, sodium hypochlorite, dan pupuk organik cair merk NASA. Metode penelitian yang digunakan adalah metode eksperimental dengan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 5 kali ulangan. Peubah yang diukur adalah produksi bahan kering dan produksi bahan organik. Konsentrasi pupuk organik cair yang diberikan yaitu pupuk organik cair 0% (P0), pupuk organik cair 0,5% (P1), pupuk organik cair 1% (P2), dan  pupuk organik cair 1,5% (P3). Hasil penelitian menunjukkan perlakuan berpengaruh sangat nyata (P<0,01) dalam meningkatkan produksi bahan kering dan bahan organik sorgum hidroponik. Hasil rataan produksi bahan kering berkisar antara 0,73 – 1,05 kg/m2 dan rataan produksi bahan organik berkisar antara 0,69-0,99 kg/m2. Berdasarkan hasil penelitian dapat disimpulkan bahwa pemberian pupuk organik cair dengan konsentrasi 1,5% dapat meningkatkan produksi bahan kering dan bahan organik tanaman sorgum hidroponik.

The aim of the research was to examine the impact of liquid organic fertilizer with various concentration and to determine the optimum concentration of fertilizer on the production of dry matter and organic matter of sorghum hydroponic fodder. Materials used in this research were sorghum seed varieties of Numbu, sodium hypochlorite, and NASA brand liquid organic fertilizer. The method was an experimental using completely randomized design (CRD) with four treatments and five replications. The variables that were measured were the productions of dry matter and organic matter. The treatments were liquid organic fertilizer 0% (P0), liquid organic fertilizer 0.5% (P1), liquid organic fertilizer 1% (P2), and liquid organic fertilizer 1.5% (P3). The results of this research showed that treatments had very significant effect on production of dry matter and organic matter sorghum hydroponic fodder (P<0.01). The average values of dry matter production were between 0.73-1.05 kg/m2 and the average values of organic matter production were between 0.69-0.99 kg/m2. This experiment concludes that the application of liquid organic fertilizer with a concentration of 1.5% can increase the production of dry matter and organic matter of sorghum hydroponic fodder.
