ABDUL BASIT, SYAHRUL and Prof. Dr. Ir. Ellis Nihayati, MS and Dr. Mochammad Roviq, S.P., M.P. (2023) Respon Pertumbuhan Dan Hasil Tanaman Kailan (Brassica Oleracea Var. Achepala) Pada Penambahan Pupuk Organik Cair. Sarjana thesis, Universitas Brawijaya.
Abstract
Kailan (Brassica oleracea var. achepala) adalah sayuran yang termasuk golongan tanaman Brassica. Kailan memiliki kandungan gizi tinggi sehingga menjadi salah satu produk pertanian yang populer dan memiliki potensi serta nilai komersial tinggi di masyarakat. Menurut BPS (2019), produksi kailan mengalami fluktuasi dari tahun 2014-2019. Upaya peningkatan produksi tanaman kailan dapat dilakukan dengan teknologi budidaya dan pemilihan varietas unggul yang tepat. Teknologi budidaya dengan pemupukan menggukan pupuk organik cair menjadi solusi dalam mengurangi penggunaan pupuk anorganik yang berlebihan karena bahan organik mampu memperbaiki sifat fisika, kimia, dan biologi tanah. Pemilihan dosis pupuk organik cair yang tepat perlu diketahui melalui pengujian di lapangan. Hasil penelitian ini diharapkan dapat memberikan informasi yang tepat mengenai dosis POC yang lebih sesuai bagi pertumbuhan dan hasil beberapa varietas kailan Nemo F1, Nita, dan Winsa. Penelitian dilaksanakan di Desa Pujon Kidul, Kab. Malang, Jawa Timur, 65391 pada bulan Desember 2022 – Januari 2023. Alat yang digunakan dalam penelitian ini adalah sprayer, tray, meteran, timbangan digital, gelas ukur, volumetric, plastik uv, dan LAM. Bahan yang digunakan dalam penelitian ini adalah benih kailan sub varietas Nemo F1, Nita, Winsa, pupuk kandang ayam, pupuk NPK 16:16:16, POC Nasa, pestisida, dan media semai. Penelitian faktorial dengan menggunakan metode Rancangan Acak Kelompok (RAK) yang terdiri dari 2 faktor yaitu Konsentrasi POC (0, 3, 6, dan 9 ml/l air) dan varietas kailan (Varietas Nemo F1 , Nita, dan Winsa) serta 3 ulangan sehingga memiliki 36 satuan percobaan. Variabel pengamatan meliputi pengamatan pertumbuhan (panjang tanaman, jumlah daun, dan diameter batang) dan hasil (berat segar total dan berat segar konsumsi). Data hasil pengamatan dianalisis dengan menggunakan analisis ragam ANOVA pada taraf 5% dan diuji lanjut dengan uji BNT taraf 5% jika berpengaruh nyata. Terdapat interaksi antara penambahan konsentrasi POC Nasa dengan sub varietas tanaman kailan pada peubah tinggi tanaman umur 14 HST, jumlah daun umur 28 HST, diameter batang umur 28-35 HST, luas daun umur 7, 21, 28 HST, bobot total, dan bobot konsumsi kailan. Penambahan konsentrasi POC 3 ml.l-1 mampu meningkatkan hasil pada sub varietas Nemo F1, sedangkan pada penambahan konsentrasi POC 9 ml.l-1 mampu meningkatkan hasil pada sub varietas Nita dan Winsa. Sub varietas Nemo F1 dan Nita menghasilkan rerata pertumbuhan dan hasil lebih tinggi dibandingkan Winsa pada peubah tinggi tanaman, jumlah daun, luas daun, bobot total, dan bobot konsumsi kailan. Konsentrasi POC 3 ml.l-1 menghasilkan rerata pertumbuhan lebih tinggi pada tinggi tanaman 28 HST dan diameter batang 7 HST. Konsentrasi POC 6 ml.l-1 menghasilkan rerata pertumbuhan lebih tinggi pada tinggi tanaman 14 dan 21ii HST, jumlah daun 21, 28, dan 35 HST, diameter batang 14, 21, dan 28 HST. Konsentrasi POC 9 ml.l-1 menghasilkan rerata pertumbuhan lebih tinggi pada tinggi tanaman 35 HST, jumlah daun 14 HST, luas daun 7, 14, 21, 28, dan 35 HST, berat segar total, dan berat segar konsumsi.
English Abstract
Kailan (Brassica oleracea var. achepala) is a vegetable belonging to the Brassica group. Kale has a high nutritional content so that it is one of the popular agricultural products and has high commercial potential and value in the community. According to Central Agency on Statistics (2019), kale’s production fluctuated from 2014 to 2019. Efforts to increase the production of kale can be done with cultivation technology and the selection of the right superior varieties. Cultivation technology with fertilization using liquid organic fertilizer is a solution in reducing the excessive use of inorganic fertilizers because organic matter can improve the physical, chemical, and biological properties of the soil. Selection of the right dose of liquid organic fertilizer needs to be known through field testing. The results of this study are expected to provide accurate information regarding the most suitable liquid organic fertilizer dose for the growth and yield of kale varieties, Nemo F1, Nita, and Winsa. The research was carried out at Pujon Kidul Village, Malang District, East Java Province, 65391 in December 2022 – January 2023. The tools used in this study were sprayers, trays, ruler, digital scales, measuring cups, volumetric flask, UV plastic, and LAM. The materials used in this study were kailan seeds of the Nemo F1, Nita, Winsa sub-varieties, chicken manure, NPK 16:16:16 fertilizer, LOF Nasa, pesticides, and seedling media. The experimental design that used was Factorial RBD (Randomized Block Design) which consists of 2 factors, namely LOF doses (0, 3, 6, and 9 ml/l water) and varieties (Nemo F1, Nita, and Winsa sub-varieties) and 3 replications so that it consist 36 units experiment. Observation variables included observations of growth (plant length, number of leaves, stem diameter, and leaf area) and yield (total fresh weight and consumption fresh weight). Observational data were analyzed using ANOVA analysis of variance at 5% level and further tested with LSD test at 5% level if it had a significant effect. There was an interaction between the addition of Nasa LOF concentration and kailan plant sub-varieties on the variables of plant height at 14 HST, number of leaves at 28 HST, stem diameter at 28-35 HST, leaf area at 7, 21, 28 HST, total weight, and consumption weight kailan. The addition of 3 ml.l-1 LOF concentration was able to increase yields on the Nemo F1 sub-variety, while the addition of 9 ml.l-1 LOF concentration was able to increase yields on the Nita and Winsa sub-varieties. Nemo F1 and Nita sub-varieties produced higher growth and yield averages than Winsa on the variables of plant height, number of leaves, leaf area, total weight, and weight of kailan consumption. LOF concentration of 3 ml.l- 1 resulted in a higher average growth in plant height 28 DAP and stem diameter 7 DAP. LOF concentration of 6 ml.l-1 resulted in higher growth rates at plant heights of 14 and 21 DAP, number of leaves 21, 28, and 35 DAP, stem diameters of 14, 21, and 28 DAP. LOF concentration of 9 ml.l-1 resulted in higher growthiv rates at plant height 35 DAP, number of leaves 14 DAP, leaf area of 7, 14, 21, 28, and 35 DAP, total fresh weight, and fresh consumption weight.
