This research was conducted from October until December 2014 located in the agricultural experimental station, Riau University. The design that used in this research was completely randomized design (CRD) consisted of 2 factors and 3 replications. The first factor waspalm oil empty fruit bunches (K) consisted of 4 levels, were: 0 g (K0), 20 g (K1), 40 g (K2) and 60 g/2 kg soil (K3). The second factor was a complementary organic liquid fertilizer (P) consisted of 4 levels, were: 0 ml (P0), 1 ml (P1), 2 ml (P2) and 3 ml/l water (P3). The result of the research showed that the interaction of palm oil empty fruit bunches and complementary organic liquid fertilizer significantly affected on the cocoa seedling’s growth. Application of  60 g/2 kg soil of palm oil empty fruit bunches and 2 ml/l water complementary organic liquid fertilizer, gave the highest result on plant height, leaf number, steam diameter, leaf area, seedling fresh  weight, crown fresh weight, root fresh weight, crown dry weight, root dry weight, crown root ratio, and cocoa seedling dry weight.
