Filter cake is one form of the sugar mill waste, however it has an beneficial value as organic fertilizer. Filter cake of canes contains some plant nutrients such as 1.51% N, 5.63% P2O5, 0.26% K2O and 32.38% C-organic elements. The use of filter cake as organic fertilizer is expected to be reduce the use of inorganic fertilizers where excessive usage over a long period that caused the degradation of soil quality if without organic in application. The purpose of this experiment is was to examine the growth of oil palm seedlings by giving filter cakes compost combined with different watering frequencies. The experiment was conducted from December 2017 to April 2018 at the Ciparanje Experimental station, Faculty of Agriculture, Padjadjaran University. A randomized block design (RBD) was used as the experimental design with four levels of fertilizer (without filter cakes (inorganic), 500, 1000, and 1500 g filter cake per plant) and the frequency of watering (every day, every 3 days, and every 5 days). The results of the experiment showed that filter cake compost of 1500 g/plant and watering of every day was the best result on growth of oil palm seedlings, particularly on the parameters of plant height, circumstance stems, number of leaves and fresh weight of plants. Filter cakes compost in this study contains 32.38% C-organic, 1.51% N, 5.63% P2O5, and 0.26% K2O.
