Pola VESICULAR ARBUSCULAR MICORRHIZAE , Batu Posfat dan Sumber-sumber Aplikasi Untuk Meningkatkan Pertumbuhan dan Panen Dari Jahe dalam TYPIC PALEUDULT

Typic Paleudult belongs to Ultisol, that has acidity and
some problems of fertilities. Another problem of it was Al-dd and Al saturation highly and to be toxic to crop. Rock phosphate application was important to be rise the soil fertility. The goal of the study was to know the role of vesicular-arbuscular Mycorrhiza, rock phosphate and N resources to raise the yield of ginger on Typic Paleudult.
