Fanani, Ahmad Rizal (2019) Pengaruh Penggunaan Macam Mulsa Dan Pupuk Nitrogen Terhadap Tanaman Cauliflower (Brassica Oleraceal.). Sarjana thesis, Universitas Brawijaya.
Abstract
Cauliflower atau sering juga disebut sebagai kembang kol (Brassica oleracea var.botritys L.) merupakan tanaman sayuran famili Brassicaceae jenis kol dengan bunga putih, berupa tumbuhan berbatang lunak yang berasal dari Eropa sub tropik.(Cahyono, 2001). Cauliflower banyak di budidayakan di daerah dataran tinggi, namun beberapa kultivar dapat membentuk bunga didaerah dataran rendah khatulistiwa. Brassicaoleracea varietas botritys terdiri atas dua subvarietas yaitu cauliflora DC dengan bunga berwarna putih yang dikenal dengan kubis bunga dan cymosa Lamn dengan bunga berwarna hijau yang dikenal dengan Brokoli (Rukmana, 1994). Pemupukan menggunakan pupuk anorganik dapat memberikan hasil yang baik bagi tanaman. Unsur hara makro khususnya N, P dan K merupakan unsur hara yang penting bagi pertumbuhan tanaman pada berbagai fase yang terjadi pada tanaman.Pupuk organik cair yang diberikan terhadap tanaman kubis bunga merangsang perkembangan luas daun. Meningkatnya perkembangan luas daun berarti kemampuan daun untuk menerima dan menyerap cahaya matahari akan lebih tinggi sehingga fotosintat dan akomodasi bahan kering akan lebih tinggi pula.Pemberian berbagai dosis kompos pada Cauliflower dapat memberikan pengaruh yang berbeda terhadap pertumbuhan tanaman Cauliflower. Pupuk kompos yang diberikan pada dosis kompos 20 ton/ha menghasilkan tanaman dan jumlah daun kubis bunga yang paling tinggi. Penelitian dilaksanakan di lahan percoban Universitas Brawijaya Kampus III, Kecamatan Mojoroto, Kota Kediri, Provinsi Jawa Timur. Ketinggian tempat penelitian yaitu 74 meter diatas permukaan laut, suhu rata-rata 20oC - 30oC, dengan kelmbaban rata-rata 82%. Curah hujan rata-rata berkisar 1000 – 2000 mm pertahun. Jenis tanah pada tempat penelitian yaitu Litosol coklat kemerahan. Penelitian dilaksanakan bulan Mei - Juli 2019. Alat yang digunakan adalah cangkul, sekop, penggaris, kamera, oven, timbangan Bahan-bahan yang digunakan yaitu bibit cauliflower, mulsa jerami, mulsa hitam perak, pupuk kandang, pupuk nitrogen, papan nama, dan bambu.disusun dalam rancang acak kelompok yang mengkombinasikan antara mulsa dan pupuk Nitrogen. Kombinasi perlakuan yang akan dilakukan yaitu sebagai berikut:P1 :Tanpa mulsa + pupuk N 100 kg/ha, P2 :Tanpa mulsa + pupuk N 125 kg/ha, P3 :Tanpa mulsa + pupuk N 150 kg/ha, P4 :Mulsa jerami + pupuk N 100 kg/ha, P5 :Mulsa jerami + pupuk N 125 kg/ha, P6 :Mulsa jerami + pupuk N 150 kg/ha, P7 :Mulsa hitam perak + pupuk N 100 kg/ha, P8 :Mulsa hitam perak + pupuk N 125 kg/ha, P9 :Mulsa hitam perak + pupuk N 150 kg/ha, yang terdiri dari 9 perlakuan yang diulang sebanyak 3 kali. Metode pengamatan meliputi persiapan bibit cauliflower, persemaian benih cauliflower, persiapan lahan, pemasangan mulsa dan penanaman. Dengan menggunakan parameter pengamatan yaitu tinggi tanaman dan jumlah daun, yang dilakukan setelah tanaman berumur 20 hari. Data yang diperoleh dari hasil pengamatan dianalisis keragamannya dan diuji berdasarkan uji F dengan taraf 5%ii sesuai dengan rancangan percobaan, dan apabila terjadi perbedaan perlakuan akan dilanjutkan dengan uji BNT dengan taraf 5%.Hasil penelitian perlakuan berbagai macam mulsa dan pupuk N didapatkan interaksi pada parameter pengamatan pertumbuhan tanaman yaitu luas daun. Perlakuan terbaik rata – rata yaitu pada perlakuan mulsa hitam perak + pupuk N 150 kg/ha (P8).
English Abstract
Cauliflower or often also referred to as cauliflower (Brassica oleracea var. Botritys L.) is a vegetable plant family of Brassicaceae type of cabbage with white flowers, in the form of soft-stemmed plants originating from sub-tropical Europe (Cahyono, 2001). Cauliflowers are widely cultivated in the highlands, but some cultivars can form flowers in the equatorial lowlands. Brassica oleracea botritys variety consists of two subvarietas namely DC cauliflora with white flowers known as cabbage flowers and Lamym cymosa with green berwarba flowers known as Broccoli (Rukmana, 1994).Fertilization using inorganic fertilizers can provide good results for plants. Macro nutrients, especially N, P and K, are important nutrients for plant growth in various phases that occur in plants. Liquid organic fertilizers applied to flower cabbage plants stimulate the development of leaf area. Increased leaf area development means that the ability of leaves to receive and absorb sunlight will be higher so that photosynthate and dry matter accommodation will be higher as well. Giving various doses of compost on Cauliflowers can have different effects on the growth of Cauliflower plants. Compost given at compost dose of 20 tons / ha produces the highest number of plants and leaves of cabbage flowers. The study was conducted in the experimental area of Brawijaya University Campus III, Mojoroto District, Kediri City, East Java Province. The height of the research site is 74 meters above sea level, the average temperature is 20oC - 30oC, with an average humidity of 82%. Average rainfall ranges from 1000 - 2000 mm per year. The type of soil at the study site is reddish brown Litosol. The study was conducted in May - July 2019. Tools used were hoes, shovels, rulers, cameras, ovens, scales. Materials used were cauliflower seeds, straw mulch, black silver mulch, manure, nitrogen fertilizer, nameplate, and bamboo. arranged in a randomized block design that combines mulch and nitrogen fertilizer. The treatment combinations that will be carried out are as follows: P1: No mulch + N fertilizer 100 kg / ha, P2: No mulch + N 125 kg / ha fertilizer, P3: Without mulch + N fertilizer 150 kg / ha, P4: Straw mulch + fertilizer N 100 kg / ha, P5: mulch straw + fertilizer N 125 kg / ha, P6: straw mulch + fertilizer N 150 kg / ha, P7: silver black mulch + fertilizer N 100 kg / ha, P8: silver black mulch + N 125 kg / ha fertilizer, P9: Silver black mulch + N 150 kg / ha fertilizer, which consists of 9 treatments repeated 3 times. Observation methods include preparation of cauliflower seeds, cauliflower seedbed, soil preparation, mulching and planting. By using observational parameters namely plant height and number of leaves, which is carried out after the plant is 20 days old. Data obtained from observations were analyzed for diversity and tested based on the F test with a level of 5% in accordance with the design of the experiment, and if there is a difference in treatment will be followed by a LSD test with a level of 5%. Observation of plant growth, namely leaf area. The best treatment on average was in the treatment of black silver mulch + N fertilizer 150 kg / ha (P8).
