    This study aimed to determine the effect of giving the boiler ash on the growth of oil palm seedlings. This research was conducted at the Experimental Farm of the Faculty of Agriculture, University of Riau, Rimbo panjang Village, Kampar regency for 4 months, starting from February 2012 to May 2012. The design used was completely randomized design (CRD) non factorial with 3 replications. As each of these factors is A0 (Without giving boiler ash), A1 (14 g / polybag boiler ash), A2 (19 g / polybag boiler ash), A3 (24 g / polybag boiler ash), A4 (29 g / polybag boiler ash). Then proceed with the trial of Duncan's New Multiple Range Test (DNMRT) at the level of 5%. Parameters observed increase plant height (cm), bulb diameter increment (cm), the number of leaves (pieces), plant dry weight (g) and root volume (ml). Based on the study conducted found that the increase in boiler ash dose given to oil palm plantations showed a significant effect on plant height increment, diameter increment hump, the number of leaves, plant dry weight and did not significantly affect root volume parameters. From this study that gives the best effect at a dose of boiler ash 29 g / polybag.
