In this research there are 16 combinations treatment with 3 replications thus obtained 48 experimental units. Each experimental unit consisted of two seedling so total number are 96 seedlings. Observation were carried out are increase of plant height, increase of leaf number, increase of diameter hump and leaf wide. The result showed that the interaction composted contents cow rumen and NPK fertilizer gave unreal effect. Composted contents cow rumen treatment and NPK fertilizer treatment were gave unreal effect. To get maximum result need continuous research with increasing dose of composted content cow rumen and NPK fertilizer.
