The research variable is percent of life tree, high tree, number of lieves, and diameter stem after that Data analysis using analysis of varian (Anova).Analysis results shows that giving oil palm buncis effect to percent of life tree, high tree, number of lieves, and diameter stem. Combinasitreathment of growing media C,D and E getting the best does to percent of life tree, as well as combination of growing media the effective to respon growth sengon is combination D for growthofhigt tree, and combinasi of growing media E for number of lieves and diameter stem.
