Aktivitas Mikroba Tanah, Pertumbuhan dan Rendemen Nilam (Pogostemon Cablin Benth.) pada Berbagai Aras Bahan Organik Serta Lengas Tanah di Ultisols
Abstract: This experiment has
been conducted to study the effect of organic matter levels and soil water content levels of Ultisols on soil
microbe activity, growth and patchouli oil content of Pogostemon cablin. Experiment was carried out
under green house condition and was arranged in completely randomized blocks
with factorial design, consisted of two factors and tree replications. First
factor was levels of organic matter (5, 7.5, and 15 ton hectare-1), and second
factor were levels of soil water content (100 %, 80 %, 60 % and 40 % of field capacity). The yield of experiment
showed that there were interaction between organic matter levels and soil water content levels on dry weight, wet weight of Pogostemon cablin and CO2
releasing but there were no interaction on dry weight and wet weight of root of
Pogostemon cablin. The highest patchouli oil content (i.e. 1.35 %) are found on
100 % level of soil water content, but on lower levels of soil water content,
patchouli oil content were decrease.
