Penelitian ini bertujuan untuk: 1) mengetahui pengaruh konsentrasi pupuk organik cair yang berbeda terhadap pertumbuhan dan hasil tanaman kubis bunga, 2) mengetahui pengaruh interval pemberian pupuk organik cair yang berbeda terhadap pertumbuhan dan hasil tanaman kubis bunga, 3) mengetahui kombinasi perlakuan konsentrasi dan interval pemberian pupuk organik cair yang terbaik bagi pertumbuhan dan hasil tanaman kubis bunga. Penelitian dilaksanakan pada bulan Oktober sampai Desember 2018 di lahan pasir pantai Desa Banjarsari, Kecamatan Nusawungu, Kabupaten Cilacap. Penelitian menggunakan Rancangan Acak Kelompok Lengkap (RAKL) faktorial yang terdiri dari 2 faktor dan 3 ulangan. Faktor pertama yaitu konsentrasi pupuk organik cair yang terdiri dari 3 taraf yaitu 0 ml liter-1, 5 ml liter-1 dan 10 ml liter-1. Faktor kedua yaitu interval pemberian pupuk organik cair yang terdiri dari 3 taraf yaitu 5 hari sekali, 10 hari sekali dan 15 hari sekali. Data dianalisis menggunakan uji F, apabila berbeda nyata dilanjutkan dengan DMRT 5%. Variabel yang diamati yaitu tinggi tanaman, jumlah daun, panjang akar, luas daun, volume akar, kadar kehijauan daun, bobot akar segar, bobot akar kering, bobot batang segar, bobot batang kering, bobot daun segar, bobot daun kering, bobot tanaman segar, bobot tanaman kering, bobot bunga segar, bobot bunga kering, umur pembentukan bunga, diameter bunga, dan hasil bunga segar. Hasil penelitian menunjukkan bahwa pupuk organik cair konsentrasi 10 ml liter-1 dengan dosis 25 ml/tan meningkatkan variabel hasil dibanding perlakuan kontrol 0 ml liter-1 pada diameter bunga 2,71 cm atau 32,93%, bobot bunga segar 40,09 gr/tan atau 56,09%, hasil bunga segar 1,6 t/ha atau 55,94%, dan umur pembentukan bunga lebih cepat 4 hari atau 10%. Interval pemberian pupuk organik cair 5 hari sekali, 10 hari sekali, dan 15 hari sekali belum mampu meningkatkan pertumbuhan dan hasil tanaman kubis bunga. Kombinasi perlakuan konsentrasi pada berbagai interval pemberian pupuk organik cair memberikan respon yang sama pada pertumbuhan dan hasil tanaman.

The purpose of this research is to:¬¬ 1) determine the effect of different liquid organic fertilizer concentrations on growth and yield of cauliflower, 2) determine the effect of different intervals of liquid organic fertilizer on growth and yield of cauliflower, 3) determine the best combination of concentration and interval providing liquid organic fertilizer for the growth and yield of cauliflower. The research was conducted in October until December 2018, at coastal sandy land of Banjarsari Village, Nusawungu Sub-district, Cilacap Regency. The research was used Randomized Complete Block Design (RCBD) factorial with 2 factors and 3 replications. The first factor is the concentration of liquid organic fertilizer which consists of 3 levels, there are 0 ml liter-1, 5 ml liter-1 dan 10 ml liter-1. The second factor is the interval of giving liquid organic fertilizer which consists of 3 levels, there are 5 days, once every 10 days and 15 days. Data were analyzed by F test, tested further by DMRT 5% if significantly different. Observed variables are plant height, number of leaves, root length, leaf area, root volume, greenish leaves, fresh root weight, dry root weight, fresh stem weight, dry stem weight, fresh leaf weight, dry leaf weight, fresh plant weight, dry plant weight, fresh flower weight, dry flower weight, the age of flower formation, flower diameter, and fresh flower yields. The results showed that the liquid concentration of 10 ml liter-1 with a dose of 25 ml / tan increased the yield variable compared to the control treatment of 0 ml liter-1 at flower diameter of 2,71 cm or 32,93%, fresh flowers weight of 40,09 gr/tan or 56,09%, fresh flower yield of 1,6 t/ha or 55.94%, and the age of flower formation is 4 days or 10% faster. The interval of giving liquid organic fertilizer 5 days, once every 10 days and 15 days has not been able to increase the growth and yield of flower cabbage plants. The combination of treatment concentrations at various intervals of giving liquid organic fertilizer gives the same response to plant growth and yield.
