The observed parameters was include: number of leaves, plant height, dry weight biomass, the longest roots, the amount of bulbs, tuber weight per plant, weight per tuber, and diameter of tuber. The result of this research was showed that giving different manure types 120 g/plant on the other hand, no siknifican diffdrent the number of leaves at 3-6 age MST, the long roots in the treatment of A0, and dry weight biomass in the treatment of A2. While, the parameters of production include the diameter of tuber, number tuber, and fresh weight tuber was not siknifican.
