Shallot is the second major horticultural crop after hot peppers in Indonesia. Demand for shallots continues to increase every year, but until now the increase in demand is not proportional to the level of production. The low national shallot production is caused by the lack of optimal production factors in shallot farming. One way to maximize the production and quality of shallots is by using seed sources from the True Shallot Seed (TSS) and by using organic fertilizers in the form of compost as a substitute for chemical synthetic fertilizers. The purpose of this study was to determine the effect of compost dosage on the growth and yield of shallot tuber Tuk Tuk cultivars from TSS seed and determine the compost dosage that can provide growth and yield of shallot tuber mini Tuk Tuk cultivars from the best TSS seed. This research was conducted at the 1 B screen house in the ITB Jatinangor campus area, Sumedang Regency. Research in the field was carried out for 16 weeks for the cultivation of shallots with a period of observation carried out every 1 week, carried out after seeding or after the plants were 6 weeks old. The research design used was a Completely Randomized Design (CRD). There are four treatments, namely the provision of compost at various doses. Treatment A or control (compost 0 g/plant), treatment B (compost 15 g/plant), treatment C (compost 30 g/plant), and treatment D (compost 45 g/plant). Compost is given at one time when transplanting. Observations were made on the growth and yield of plants in the form of plant height, number of leaves, wet stover weight, dry stover weight, dry protolan weight, and tuber diameter. The results showed that administration of compost significantly affected the growth and yield of shallots (P <0.05). The compost dosage that gives the best results on the growth of shallots is treatment D with a growth rate of 2.22 cm per week and a growth rate of 0.33 leaves per week. While the dosage of compost that gives the best results on the results of shallots is the dose in treatment C with an average weight of wet stover 6.15 g; average dry stover weight 4.15 g; average weight of dried tubers 2.05 g; and the average diameter of the tuber is 1.13 cm.
