Abstrak

Penelitian ini bertujuan untuk mengetahui respon pertumbuhan tanaman jagung setelah pemberian pupuk Urea, SP-36 dan KCl. Penelitian dilaksanakan pada bulan April-Juni 2015 di rumah kaca dan Laboratorium Ilmu Tanaman Jurusan Budidaya Pertanian, Fakultas Pertanian, Universitas Gadjah Mada Yogyakarta. Penelitian ini menggunakan rancangan acak lengkap (RAL) dengan kombinasi pemupukan yang terdiri atas :kontrol (tidak dipupuk), tanpa N (PK), tanpa P (NK), tanpa K (NP), dan lengkap (NPK). Setiap perlakuan diulang sebanyak 3 kali. Pengamatan tanaman dilakukan pada umur 8 mst yang meliputi tinggi tanaman, klorofil, panjang akar, luas akar, volume akar, berat kering akar
dan bobot kering total tanaman. Hasil penelitian menunjukkan bahwa pemberian pupuk Urea (N) dan Kalium (K2O5) dapat meningkatkan panjang akar dan luas akar jagung sebesar 152, 32 % dan 116,12% terhadap tanaman tanpa diberi pupuk (kontrol). Tinggi tanaman meningkat sebesar 6,43% setelah diberi pupuk NK terhadap tanaman kontrol.
