Background and Objective: The use of shallot varieties and sources of the eco enzyme as organic fertilizer is an alternative effort to increase the productivity of shallot bulbs. The study aims to determine the growth and production response of shallot varieties on the application of potassium sources from the eco enzyme. Materials and Methods: This research was conducted in the experimental land of the Faculty of Agriculture, Universitas Sumatera Utara from February-April, 2021, used a factorial randomized block design. The first factor is the variety of shallots from the bulb (Lokananta and Sanren F1) and the second factor is the potassium source from the eco enzyme (control, orange peel 20 ml L^–1, chicory 15 ml L^–1 and pineapple skin 20 ml L^–1). Result: The results showed that the Lokananta variety has a plant height of 3-7 weeks after planting, wet weight of the bulb and dry weight of bulb higher compared to Sanren F1. The treatment without eco enzyme (control), chicory and orange peel eco enzymes produced a wet weight of shoot, bulb wet weight and bulb dry weight higher compared to pineapple skin eco enzyme. The interaction between Lokananta variety with eco enzyme chicory orange peel and control resulted in bulb wet weight and bulb dry weight higher compared to pineapple skin treatment. Conclusion: The use of eco-enzyme chicory in Lokananta increased bulb dry weight by 20.47% compared to control. In the Sanren variety, the application of eco-enzyme chicory orange peel and pineapple skin reduced the bulb dry weight by, respectively 18.41, 37.78 and 26.29%.
