Tanaman bunga kol banyak digemari oleh masyarakat Indonesia. Penggunaan pupuk kimia dapat mengancam keseimbangan ekosistem dan menurunkan kesuburan tanah. Upaya dalam mengurangi penggunaan pupuk kimia yaitu dengan menggunakan pupuk organik cair. Penelitian ini untuk mengetahui, mengukur dan menganalisis pemberian jenis dan konsentrasi pupuk organik cair yang berbeda untuk meningkatkan pertumbuhan dan hasil bunga kol. Bahan yang digunakan yaitu pupuk ZA, pupuk SP-36, pupuk KCl, air, benih bunga kol varietas PM 126 F1, pupuk kandang kambing, POC Nasa, POC Green Tonik dan POC Bio Sugih. Penelitian ini menggunakan rancangan acak kelompok (RAK) dengan kombinasi perlakuan P1: POC Nasa 1 ml/l Air, P2: POC Nasa 2 ml/l Air, P3: POC Nasa 3 ml/l Air, P4: POC Green Tonik 1 ml/l Air, P5: POC Green Tonik 2 ml/l Air, P6: POC Green Tonik 3 ml/l Air, P7: POC Bio Sugih 1 ml/l Air, P8: POC Bio Sugih 2 ml/l Air, P9: POC Bio Sugih 3 ml/l Air. Penelitian dilaksanakan pada bulan Februari hingga April 2022 di Lahan Percobaan Fakultas Pertanian Universitas Brawijaya, Kelurahan Jatimulyo, Jawa Timur. Hasil penelitian menunjukkan bahwa Jenis dan konsentrasi POC Green Tonik 3 ml/l memberikan hasil terbaik terhadap pertumbuhan dan hasil tanaman bunga kol. Pemberian POC Green Tonik 3 ml/l menghasilkan panen bunga kol per hektar sebesar 15,67 t ha-1 atau lebih tinggi 56,7% dibandingkan POC Green Tonik 1 ml/l. Kata kunci: Bio Sugih, Bunga Kol, Green Tonik, Nasa. Cauliflower plants are much favored by the people of Indonesia. The use of chemical fertilizers can threaten the balance of the ecosystem and reduce soil fertility. Efforts to reduce the use of chemical fertilizers are by using liquid organic fertilizers. This study was to determine, measure and analyze the application of different types and concentrations of liquid organic fertilizer to increase the growth and yield of cauliflower. The materials used were ZA fertilizer, SP-36 fertilizer, KCl fertilizer, water, cauliflower seeds of PM 126 F1 variety, goat manure, Nasa POC, Green Tonic POC and Bio Sugih POC. This study used a randomized block design (RAK) with a combination of treatments P1: POC Nasa 1 ml/l Water, P2: POC Nasa 2 ml/l Water, P3: POC Nasa 3 ml/l Water, P4: POC Green Tonic 1 ml/l l Water, P5: POC Green Tonic 2 ml/l Water, P6: POC Green Tonic 3 ml/l Water, P7: POC Bio Sugih 1 ml/l Water, P8: POC Bio Sugih 2 ml/l Water, P9: POC Bio Sugih 3 ml/l Water. The research was carried out from February to April 2022 at the Experimental Field of the Faculty of Agriculture, Universitas Brawijaya, Jatimulyo Village, East Java. The results showed that the type and concentration of POC Green Tonic 3 ml/l gave the best results on the growth and yield of cauliflower plants. Giving POC Green Tonic 3 ml/l resulted in cauliflower harvest per hectare of 15.67 t ha-1 or 56.7% higher than POC Green Tonic 1 ml/l. Keywords: Bio Sugih, Cauliflower, Green Tonic, Nasa.
