Abstract

Ubi Alabio (Dioscorea alata L.) memiliki potensi sebagai pangan fungsional di Kalimantan Selatan namun belum optimal dari segi budidaya. Aplikasi pupuk hijau dari gulma air menjadi altenatif pemupukan ramah lingkungan. Pendekatan karakter morfologi dan fisiologi kaitannya dengan fotosintesis dapat dilakukan untuk melihat efektivitas pemupukan. Penelitian ini bertujuan mempelajari karakter morfologi dan fisiologi daun ubi alabio perbedaan aplikasi pupuk hijau di lahan rawa lebak. Pemberian berbagai jenis pupuk hijau tidak berpengaruh terhadap karakter morfologi daun ubi alabio yang meliputi panjang, lebar dan luas daun. Karakter fisiologi daun yaitu berat kering daun dan kandungan klorofil b serta klorofil total juga tidak menunjukkan perbedaan pada aplikasi berbagai jenis pupuk hijau, akan tetapi tren data menunjukkan pupuk hijau kayu apu memebrikan karakter cukup baik dibanding pupuk lain. Aplikasi pupuk kayu apu 35 ton ha^-1 menghasilkan kandungan klorofil a paling tinggi pada daun ubi alabio yaitu berkisar antara 4,556-6,900
