Research conducted at the Experiment Berastagi in March - June, 2013, using a factorial randomized
block design with two factors: the concentration of organic manure (0, 5, 10 ml / L) and NPK fertilizer
doses (0, 5, 10 and 15 g / polybag ). The parameters measured were plant height, stem diameter, crown
width, of the number of leaves, number of leaf chlorophyle and total leaf area. The results showed that
the liquid fertilizer oganik significant effect on the amount of leaf chlorophyll but not significant effect
on other parameters. NPK fertilizer significant effect on plant height, stem diameter, crown width, of the
number of leaves, and total leaf area. Their interaction effect was not significant on all variables
