Efek Inokulasi Cendawan Mikoriza Arbuskular Indigen dan Sistem Olah Tanah Terhadap Keefektifan Mikoriza, Komponen Hasil, dan Hasil Padi Gogo (Oriza sativa L.) pada Ultisols

Abstract

Effect of Inoculation of Indegenous Population of Arbuscular Mycorrhiza Fungi and Tillage Systems of Mycorrhiza Effectiveness, Yield Components, and Yield of Upland Rice (Oryza sativa L.) on Ultisols

ABSTRACT. The field experiment was conducted to study the growth characteristics, agronomy characteristics, and yield of upland rice on ultisols with various dosages of AMF inoculants on three tillage systems. The experiment was carried out Kampung Baru village, Bandar Lampung City from April until August 2005. The experiment used a spilt plot pattern in randomized block design. The main plot was soil tillage systems with consisted of three levels, those were intensive tillage, minimum tillage, and no tillage; and sub plot was AMF inoculants dosages with consisted of four levels, those were 0, 6.0, 13.0, and 19.50 ton ha^-1. The result of experiment showed that tillage systems and AMF inoculants affected produces the highest yield for rice, and this yield depend on tillage systems. The highest yield of rice was 3,559.03 g 8m^-2 obtained of optimum dosage 13 ton ha^-1 AMF inoculants in minimum tillage.
