This research has been conducted in the field of Agriculture Faculty of the Islamic University of Riau. The parameters observed in this study were the increase of plant height cm , the increase of the number of stem strands , the length of the longest stem length cm , the increase of girth cm , the number of root root root and root length cm.
The result of the research showed that the interaction of TKKS compost and NPK fertilizer gave a significant effect on the plant height increase, the increase of midrib, the length of the longest bark and the increase of girth. The main effect of TKKS compost and NPK fertilizer gave a significant effect on all parameters in the range of plant height, the increase of midrib, the length of the longest stem, the increase of girth, the number of root roots and the longest root length.
