The objective of this study was to evaluate the growth response of oil palm seedlings to the application of Sugarcane Filter Cake (blotong) and PGPR at the pre-nursery stage. The research was conducted at the Research and Educational Garden ( Experimental farm) in Maguwohardjo Village, Depok Sub-district, Sleman Regency, Special Region of Yogyakarta. This study took place from December 2024 to March 2025. The research method used was a factorial experiment arranged in a Completely Randomized Design (CRD) with two factors. The first factor was the dosage of Sugarcane Filter Cake, with four treatment levels: control (NPK 3 gram), 100 g, 150 g, and 200 g per seedling. The second factor was the application of PGPR, with four concentration levels: control (0 ml), 5 ml, 10 ml, and 15 ml per polybag. The data were analysed using Analysis of Variance (ANOVA), and the results were further tested using Duncan’s Multiple Range Test (DMRT) at a 5% significance level. The observed parameters included plant height, number of leaves, stem diameter, shoot fresh weight, shoot dry weight, root fresh weight, root dry weight, root volume, and leaf area. The results showed no interaction between the Sugarcane Filter Cake dosage and PGPR concentration in influencing the growth of oil palm seedlings. The application of a 100 g dose of Sugarcane Filter Cake per seedling showed optimal growth for the parameters of plant height and number of leaves.The application of sugarcane filter cake can replace in the NPK fertilizer. The application of PGPR up to a concentration of 15 ml did not have a significant effect on any of the observed parameters for the oil palm seedlings in the pre-nursery.
