Abstract
Tanaman bunga kol merupakan salah satu anggota keluarga kubis-kubisan yang banyak digemari oleh masyarakat Indonesia. Kebutuhan bunga kol di Indonesia semakin meningkat setiap tahun. Namun, produksi tanaman bunga kol di Indonesia masih tergolong rendah. Salah satu faktor penting untuk meningkatkan produktivitas tanaman bunga kol adalah pemenuhan unsur hara. Dalam memenuhi kebutuhan hara pada tanaman bunga kol, para petani biasa menggunakan pupuk kimia secara terus menerus karena cenderung mudah di dapat dan memberikan hasil yang cepat. Namun, penggunaan pupuk kimia secara berlebihan dan terus menerus dapat mengancam keseimbangan ekosistem dan menurunkan kesuburan tanah. Penggunaan sumber- sumber organik dapat menjadi salah satu solusi dalam menanam tanaman bunga kol sehingga lebih menguntungkan bagi masyarakat juga bagi petani. Maka dari itu, penelitian ini dilakukan untuk mengetahui pengaruh jenis dan konsentrasi pupuk organik cair (POC) yang yang berbeda terhadap pertumbuhan dan hasil tanaman bunga kol. Penelitian ini dilaksanakan di Lahan Percobaan Fakultas Pertanian Universitas Brawijaya, Kelurahan Jatimulyo, Kecamatan Lowokwaru, Kota Malang, Jawa Timur pada bulan Februari 2022 hingga bulan April 2022. Alat yang digunakan dalam penelitian ini yaitu gunting, kertas label, plastik semai, papan alphaboard, cangkul, cetok, jangka sorong, pisau, ember, gembor 10 liter, kamera, timbangan analitik, dan alat tulis. Bahan yang digunakan berupa pupuk air, benih bunga kol varietas PM 126 F1, pupuk ZA, SP-36 dan KCL, POC Nasa, POC Green Tonik dan POC Bio Sugih. Rancangan penelitian menggunakan Rancangan Acak Kelompok (RAK) yang terdiri dari 9 kombinasi perlakuan dengan 3 kali pengulangan, sehingga diperoleh 27 satuan plot perlakuan. Setiap plot terdiri dari 40 tanaman sehingga total tanaman sebanyak 1.080 tanaman. Kombinasi perlakuan di lapang yaitu 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. Data pengamatan yang telah didapatkan dianalisis menggunakan analisis ragam dengan uji F pada taraf 5% dan dilanjutkan dengan uji Beda Nyata Terkecil (BNT) pada taraf 5%. Hasil penelitian menunjukan bahwa Kombinasi jenis dan konsentrasi pupuk organik cair (POC) yaitu pupuk Nasa, Green Tonik dan Bio Sugih dengan konsentrasi 1 ml/l, 2 ml/l dan 3 ml/l berpengaruh terhadap pertumbuhan dan hasil tanaman bunga kol (Brassica oleracea var. botrytis L.). 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 ton ha-1 atau lebih tinggi 56,7% dibandingkan POC Green Tonik 1 ml/l.
English Abstract
Cauliflower plants are one of the members of the cabbage family that are much favored by the people of Indonesia. The need for cauliflower in Indonesia is increasing every year. However, the production of cauliflower in Indonesia is still relatively low. One of the important factors in increasing the productivity of cauliflower is the fulfillment of nutrients. In meeting the nutrient needs of cauliflower plants, farmers usually use chemical fertilizers continuously because they tend to be easy to obtain and provide fast results. However, excessive and continuous use of chemical fertilizers can threaten the balance of the ecosystem and reduce soil fertility. Organic sources can be one solution to growing cauliflower plants so that it is more profitable for the community as well as for farmers Therefore, this study was conducted to determine the effect of different types and concentrations of liquid organic fertilizer on the growth and yield of cauliflower. The research was carried out at the Experimental Field of the Faculty of Agriculture, Universitas Brawijaya, Jatimulyo Village, Lowokwaru District, Malang City, East Java, from February 2022 to April 2022. The tools used in this study were scissors, label paper, plastic seedlings, alphaboard, hoe, squeegee, caliper, knife, bucket, 10 liter gembor, camera, analitical scales, and stationery. The materials used were water, cauliflower seeds of PM 126 F1 variety, ZA, KCL and SP-36 manure, Nasa POC, Green Tonic POC and Bio Sugih POC. The research design used a Randomized Block Design (RAK) consisting of 9 treatment combinations with 3 repetitions, in order to obtain 27 treatment plot units. Each plot consisted of 40 plants for a total of 1.080 plants. The combination of treatments in the field were 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 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. Observational data that has been obtained was analyzed using analysis of variance with the F test at the 5% level and then it is continued with the Least Significant Difference (LSD) test at the 5% level. The results showed that the combination of types and concentrations of liquid organic fertilizer, namely Nasa, Green Tonik and Bio Sugih fertilizers with concentrations of 1 ml/l, 2 ml/l and 3 ml/l affected the growth and yield of cauliflower (Brassica oleracea). var. botrytis L.). 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 tons ha-1 or 56.7% higher than POC Green Tonic 1 ml/l
