This study aims to determine the effect of giving empty bunch compost (KOTAKPLUS) on the growth and production of red lettuce (Lactuca sativa Var. Crispa) verticulture. This study used a non-factorial randomized block design (RBD) with 5 levels of treatment, namely the provision of empty bunch compost (KOTAKPLUS) consisting of: A0 = Top soil, A1 = 3: 1 ratio (Top Soil: (KOTAKPLUS), A2 = Comparison 2: 2 (Top Soil: KOTAKPLUS). A3 = Ratio 1: 3 (Top Soil: KOTAKPLUS), and A4 = Box Plus 100%. The parameters observed consisted of Plant Height (cm), Number of Leaves (cm), Leaf Width (cm ), Plant Weight per Plot (kg), and Consumption Weight per Plot (kg). Based on the results of the study, it can be concluded that the provision of empty bunch compost (KOTAKPLUS) has a significant effect on all growth parameters and production of red lettuce (Lactuca sativa Var. Crispa) ) verticulture, with the best treatment found in the A3 (Top Soil 1: 3 Compost KOTAKPLUS) treatment, with an average plant height of 13.40 cm, number of leaves 9.67, leaf width 8.98 cm, plant weight per plot of 3.17 kg, and consumption weight per plot of 2.28 kg .
