jenis ubi jalar, klon lokal Saree, varietas CilembuAbstract
Tanaman ubi jalar merupakan tanaman umbi-umbian yang dapat ditingkatkan hasilnya dengan pemberian dosis pupuk kalium pada klon lokal Saree yang sudah beradaptasi di daerah asalnya. Tujuan dari penelitian ini yaitu untuk mengetahui dosis pupuk KCl dan jenis ubi jalar yang sesuai serta interaksi antara keduanya terhadap hasil ubi jalar. Penelitian ini dilaksanakan di dataran menegah Saree, Kabupaten Aceh Besar dan Laboratorium Fisiologi Tumbuhan Fakultas Pertanian Universitas Syiah Kuala dari April hingga Agustus 2023. Penelitian ini menggunakan Rancangan Acak Kelompok pola faktorial 4 x 2 dengan 3 ulangan yang terdiri dari dua faktor. Faktor pertama adalah dosis pupuk KCl (0, 100, 200, dan 300 kg ha-1). Faktor kedua adalah jenis ubi jalar (klon lokal Saree dan varietas Cilembu). Hasil penelitian menunjukan bahwa dosis pupuk kalium 300 kg ha-1 terbaik untuk parameter hasil umbi ubi jalar, sedangkan varietas Cilembu cenderung lebih baik untuk parameter hasil umbi ubi jalar.
