Daftar Isi:
- Penelitian ini bertujuan untuk menganalisis peran abu sekam dan tingkat ketersediaan air dalam peningkatan pertumbuhan, hasil dan kandungan flavonoid bawang dayak. Penelitian dilaksanakan pada bulan Mei sampai dengan Oktober 2022 di Rumah Kaca Fakultas Pertanian Universitas Lambung Mangkurat. Rancangan yang digunakan adalah rancangan acak kelompok (RAK) dua faktor berulangan 3, faktor pertama dosis abu sekam terdiri dari 4 taraf: 0 ton ha-1, 2.5 ton ha-1, 5 ton ha-1, dan 7.5 ton ha-1, dan faktor kedua adalah tingkat ketersediaan air terdiri dari 4 taraf: 100% kapasitas lapang, 75% kapasitas lapang, 50% kapasitas lapang dan 25% kapasitas lapang. Hasil penelitian menunjukkan bahwa aplikasi abu sekam dapat meningkatkan jumlah daun, jumlah anakan, berat umbi dan kandungan flavonoid pada umbi bawang dayak. Kandungan flavonoid tertinggi sebesar 0.101% diperoleh pada dosis abu sekam 7.5 ton ha-1. Perlakuan ketersediaan air di bawah kapasitas lapang cenderung menurunkan pertumbuhan, hasil, dan kandungan flavonoid bawang dayak. Berat kering umbi lebih memberikan pengaruh terhadap kandungan flavonoid umbi bawang dayak dibandingkan jumlah umbi. Kata kunci: amelioran, kapasitas lapang, metabolit sekunder, tanaman obat
- The study aimed to analyze the role of rice husk ash dose and water availability in increasing growth, yield and flavonoid content of Dayak onions. The research was carried out from May to October 2022 in the Greenhouse at Faculty of Agriculture, Lambung Mangkurat University. The design used was a two-factor randomized block design with 3 repetitions, the first factor of rice husk ash dosage consisted of 4 levels: 0 ton ha-1, 2.5 ton ha-1, 5 ton ha-1, dan 7.5 ton ha-1, and the second factor was the level of water availability consisting of 4 levels: 100% field capacity, 75% field capacity, 50% field capacity and 25% field capacity. The results showed that application of rice husk ash might increase the number of leaves, number of tillers, weight of bulbs, and flavonoid content in Dayak onion bulbs. The highest flavonoid content of 0.101%, was obtained at a dose of 7.5 ton ha-1. The treatment of water availability below field capacity tended to reduce the growth, yield and flavonoid content of Dayak onions. The dry weight of the bulbs has more influence on the flavonoid content of Dayak onion bulbs rather than the number of bulbs.
