Abstract

  ABSTRAKKubis bunga merupakan sayuran yang digemari masyarakat, karena  rasanya lezat, mengandung antioksidan dan bergizi tinggi. Konsumsi kubis bunga di Indonesia meningkat setiap tahunnya. Pada tahun 2018 permintaan kubis mencapai 1.45 kg/kapita/tahun yang setara dengan  384 250 ton. Sementara itu produksi kubis bunga pada tahun 2018 mencapai 152 122 ton  dan pada tahun 2019 mencapai 183 816 ton. Produksi kubis bunga yang ada belum mampu mencukupi permintaan. Salah satu upaya untuk meningkatkan produksi di antaranya adalah dengan pemupukan. Penelitian ini bertujuan mempelajari pengaruh interaksi pupuk cair D.I. Grow dan macam varietas terhadap pertumbuhan dan hasil kubis bunga.  Penelitian  dilaksanakan  di Dusun Tawangrejo Desa Mukuh Kecamatan Kayenkidul Kabupaten Kediri, dengan tinggi tanah 111 dpl, jenis tanah Regosol, pH tanah 5.5-6.0.  Percobaan dilakukan menggunakan Rancangan Acak Kelompok (RAK) faktorial yang  diulang  3 kali. Faktor pertama adalah konsentrasi pupuk organik cair D.I Grow dengan empat level yaitu (D0=tanpa perlakuan konsentrasi  pupuk cair;  D1= 2.5 ml/l; D2=5.0 ml/l dan D3=7.5ml/l). Faktor kedua adalah varietas kubis bunga (V1=Varietas Kusuma, V2=Cauliflower Spring 46, danV3=PM 126). Hasil  penelitian  adalah terdapat interaksi antara pemberian pupuk cair D.I. Grow  dan varietas kubis bunga. Kombinasi perlakuan D3V2 memberikan pertumbuhan dan hasil kubis bunga yang paling baik.    ABSTRACTCauliflower is a vegetables that is liked by the community, because it tastes delicious, contains antioxidants and highly nutritious. Consumption of flower cabbage in Indonesia is increasing each year. In 2018 the demand for cabbage reached 1.45 kg/capita/year which is equivalent to 384 250 tons. Meanwhile, flower cabbage production in 2018 reached 152 122 tons and in 2019 it reached 183 816 tons. The existing production of flower cabbage has not been able to meet the demand. One of the efforts to increase production is fertilizer application. This study aims to study the effect of the interaction of D.I. Grow liquid fertilizer  and kinds of varieties on the growth and yield of cauliflower. The research was carried out in Tawangrejo Dusun, Mukuh Village, Kayenkidul District, Kediri Regency, with the altitude of 111 above sea level, soil type Regosol, soil pH 5.5-6.0. The experiment was conducted using a factorial Randomized Block Design  which was repeated 3 times. The first factor is the concentration of liquid organic fertilizer D.I Grow with four levels, namely (D0=without liquid fertilizer concentration treatment; D1=2.5 ml/l; D2=5.0 ml/l and D3=7.5ml/l). The second factor was the cauliflower variety (V1=Kusuma variety, V2=Cauliflower Spring 46, and V3=PM 126). The result of the research is that there is an interaction between the application of liquid fertilizer D.I. Grow and cauliflower varieties. The combination of D3V2 treatment gave the best growth and yield of cauliflower.

Abstract

ABSTRAKAnalisis tanah merupakan kegiatan berskala laboratorium yang bertujuan mengetahui serta menetapkan kualitas atau kesuburan tanah. Kualitas dan kesuburan tanah dipengaruhi oleh sifat-sifat fisika, kimia, dan biologi. Penelitian ini menguji beberapa parameter fisika dan kimia, di antaranya adalah kadar air, karbon organik, fosfor, nitrogen, kalium, pH, dan tekstur tanah. Parameter biologi tanah, yaitu jumlah mikroorganisme di dalam tanah, tidak diukur pada penelitian ini. Hal ini dikarenakan berdasarkan hasil penelitian sebelumnya kadar C-organik berbanding lurus dengan jumlah mikroorganisme tanah. Contoh tanah diperoleh dari Kota Batu Jawa Timur pada bulan Februari-Mei 2022. Penelitian dilakukan di Laboratorium Tanah BPTP Jawa Timur dengan menggunakan metode analisis sebagai berikut: gravimetri, spektrofotometri UV-Vis, Kjeldahl, perkolasi, atomic absorption spectroscopy (AAS), dan hydrometer. Hasil analisis contoh tanah dengan kode 66, 67, dan 115, berturut-turut adalah: kadar air 11,65%; 6,62%; dan 8,25%; karbon organik 0,95% (rendah), 1,43% (rendah) dan 0,93% (rendah); fosfor 12,69 ppm (sedang), 6,00 ppm (rendah) dan 34,75 ppm (tinggi); nitrogen 0,15% (rendah), 0,17% (rendah) dan 0,13% (rendah); kalium 0,36 cmol(+)/kg (rendah), 0,54 cmol (+)/kg (sedang), dan 0,66 cmol (+)/kg (tinggi); pH 4,6 (masam), 5,1 (masam), dan 5,5 (masam); tekstur liat, lempung berliat, dan liat. Hasil analisis contoh tanah tidak dikorelasikan dengan pertumbuhan tanaman, karena setiap jenis tanaman memiliki kondisi yang berbeda-beda. Secara umum hasil analisis tanah angka yang rendah, sehingga perlu dilakukan pemupukan secara berkala pada tanah tersebut, baik menggunakan pupuk organik ataupun campuran antara pupuk organik dan pupuk kimia, dengan dosis yang sesuai dengan kebutuhan tanaman. ABSTRACTSoil analysis is a laboratory-scale activity that aims to knows and determine the quality and fertility of soil. Soil quality and fertility are influenced by physical, chemical, and biological properties. This study tested several physical and chemical parameters, including water content, organic carbon, phosphorus, nitrogen, potassium, pH, and soil texture. Soil biological parameters, namely the number of microorganisms in the soil, were not measured in this study, because based on the results of previous studies, the content of organic carbon was directly proportional to the amount of soil microorganisms. Soil samples were taken from Batu Regency, East Java, from February to Mei 2022. This research was conducted at Soil Laboratory – BPTP East Java, using the following analytical methods: gravimetric, UV-Vis spectrophotometry, Kjeldahl, percolation, atomic absorption spectroscopy (AAS), and hydrometer. The results of analysis soil samples in this research with codes 66, 67, and 115, respectively were: water content 11.65%; 6.62%; and 8.25%; organic carbon 0.95% (low), 1.43% (low) and 0.93% (low); phosphorus 12.69 ppm (medium), 6.00 ppm (low) and 34.75 ppm (high); nitrogen 0.15% (low), 0.17% (low) and 0.13% (low); potassium 0.36 cmol(+)/kg (low), 0.54 cmol(+)/kg (moderate), and 0.66 cmol(+)/kg (high); pH 4.6 (sour), 5.1 (sour), and 5.5 (sour); soil textures are clay, loamy clay, and clay. The results of soil sample analysis in this research were not correlated with plant growth, because in every plant had a different conditions.
