Land that is still stretching and enough potential to be developed into plantation land is peat land. One of the alternatives in the utilization of peat land is to utilize the soil microorganisms which cellulolitic microorganisms is one type of soil microorganisms that play a role in the reform process of organic materials through enzymatic hydrolysis with cellulase enzymes as catalysts. The research was conducted at an area with peat soil as growth media was taken from desa Rimbo Panjang Kab. Kampar Province of Riau by Factorial Completely Randomized Design with three replication. The first factor consist of: 0, 10, 20 and 30 (ml/polybag) of cellulolytic mikrorganism. The second factor consist of: 2, 3 and 4 (times/day) watering.. The parameters observed were plant height, leaf number, and wrap bulbs. The results showed that the ideal number of leaves occurred on providing MOS 10 ml/polybag with watering 3x a day, and the best stump diameter on treatment provision MOS 20 ml/polybag with watering 3x a day.enCellulolytic MicroorganismsWateringOil PalmPeat SoiLPre nurseryUR-Scientific Work Lecturer
