Fertilization using organic materials has a double benefit in preserving the environment and plant growth. This study aims to determine the effectiveness of the application method of liquid organic fertilizer (LOF) with various concentrations on lettuce plants’ growth. The research method used was experimental research using a factorial complete randomized design. Factor 1 is the concentration of liquid organic fertilizer (LOF) (10, 15, 20, 25, 30 ml l −1 ), and Factor 2 is the method of applying LOF (spray, watering, and combination spray and watering). Each unit of the experiment was repeated three times. Growth and yield parameters observed in this study: plant height, leaf area, dry weight, and fresh plant weight. The data of growth parameters and lettuce yields were then analyzed using variance analysis at 5% level and Duncan’s test at 5% level. The results showed an interaction between the application method and LOF concentration on leaf area, dry weight, and fresh weight. The independent effect occurs on plant height parameters. The application of LOF concentrations of 15 ml l −1 in lettuce plants using watering and spraying is more effective than the other treatment.
