Aplikasi Pupuk Organik terhadap Pertumbuhan Jati Unggul Nusantara (JUN) UBH-KPWN di Kecamatan Rancabungur Kabupaten Bogor

Abstract

Jati Unggul Nusantara (JUN) is the type of teak tree produced by biotechnology through vegetative propagation with cuttings and rooting system modifications done to produce good root compound. The type of this fast-growing teak, sturdy and can be harvested from the age of 5 years and has a good phenotype quality. The purpose of this research is to know the growth rate of JUN with different doses of organic fertilizer treatment. Variable measured of tree are diameter, total height, clear bole height and canopy projection, and made observations on the relative growth rate of them. Organic fertilizer gives a significant influence on the confidence interval of 95% for the diameter at doses of 150 grams and canopy projection JUN at doses of 200 grams. As well as fertilizers dose 150 grams provide a tangible influence on the growth rate of diameter, plant height and canopy projection.
