This research was conducted with the aim of determining the effect of several mixtures of liquid compost with the addition of banana peel and sweet potato peel on the growth, productivity, and quantity of red ruble kale (Brassica napus var. pabularia), as well as identifying the treatment that can produce red ruble kale with the highest productivity and plant quality. The research method used was a randomized block design (RBD) with 4 treatments of mixed compost materials, namely urine+cow milk+free-range chicken egg (UST), urine+cow milk+free-range chicken egg+banana peel (UST+BP), urine+cow milk+free-range chicken egg+banana peel (UST+KP), urine+cow milk+free-range chicken egg+banana peel+sweet potato peel (UST+BP+SP), repeated six times and multiplied by two for quantity and quality testing, resulting in 48 experimental units. Vitamin C test was used as a quality parameter, productivity parameters included wet weight harvest index and R/S ratio, and growth parameters included leaf number, plant height, and stem diameter. Data were analyzed using Anova variance test. Based on the results of the variance test, the mixture of several compost materials had a significant effect on growth parameters, and then had a significant effect on productivity parameters such as wet weight harvest index, but did not show a significant difference for harvest index, R/S ratio. In terms of vitamin C content, it showed significant results, while for anthocyanin parameters, the best results were obtained from the treatment of urine+cow milk+free-range chicken egg+sweet potato peel (UST+KU).
