    Optimal increase in rubber production should start with the selection of superior clones, use of quality seeds and good maintenance. This study aimed to determine the effect of dose on the growth of municipal waste compost seedling clones of rubber tree latex-rubber seedling growth and getting better. Research carried out for 4 months starting from October 2012 to January 2013 in UPT (Technical Implementation Unit), Experimental Farm Faculty of Agriculture, University of Riau Pekanbaru. Research conducted experiments using a completely randomized design (CRD) which are arranged in factorial consisting of two factors: The first factor is the dose that consists of compost composting A1 = 30 g / polybag, composting A2 = 40 g / polybag, A3 composting = 50 g / polybag. Factor II is a rubber seed clones producing latex-timber comprising IRR K1 = 5, K2 = IRR 118. The data obtained were statistically analyzed using analysis of variance and Duncan's test further with the New Multiple Range Test (DNMRT) at the level of 5%. Parameters measured were seedling height (cm), number of leaves (pieces), trunk circumference (cm), seedling dry weight, root crown ratio, and seed quality index. The results showed that the combination treatment of compost 50 g / polybag (20 tons / ha) in clones of IRR 5 that can increase seedling height, number of leaves, stem circumference, seedling dry weight, crown root ratio and seed quality index.
