Oil palm is an important plantation commodity that requires proper nutrient management from the nursery stage to support optimal growth. This study aimed to determine the effect of various concentrations of liquid organic fertilizer (LOF) derived from tofu waste on the growth of oil palm seedlings (Elaeis guineensis Jacq.) during the early nursery (pre-nursery) stage. The research was conducted at the Agrotech Training Center (ATC), Faculty of Agriculture, Sriwijaya University, Indralaya Utara District, Ogan Ilir Regency, South Sumatra, from August to October 2025.This study employed a Randomized Block Design (RBD) consisting of seven treatments: P0 (control), P1 (5%), P2 (10%), P3 (15%), P4 (20%), P5 (25%), and P6 (30%) concentrations of tofu waste LOF. The observed data were analyzed using analysis of variance (ANOVA), and if significant effects were found, further testing was carried out using Duncan’s Multiple Range Test (DMRT).The results of the analysis showed that the application of tofu waste LOF had a highly significant effect on seedling height at 12 weeks after planting (WAP) and leaf area at 12 WAP. The variation in LOF concentration had a significant effect on stem diameter at 12 WAP and soil pH. However, it had no significant effect on the number of leaves, leaf thickness, leaf greenness, and root volume at 12 WAP. The application of 20% tofu waste LOF was found to be the optimal concentration for oil palm seedlings during the early nursery stage. Keywords: agro-industrial waste, vegetative growth, organic fertilization
