Abstract
Background and Objective: The productivity of shallots in Indonesia is low. Productivity on average is only 9 t ha-1. That is far from the potential to produce up to 15 t ha-1. The research aims to evaluate the yield potential of planting material in the form of seed tubers, aerial tubers and in vitro culture tubers. Materials and Methods: The study was carried out at experimental field, ecology laboratory and in vitro Culture Laboratory from October, 2018-June, 2019. The study was conducted in two seasons. The first season to produce planting material such as; True Shallot Seed (TSS) tuber seeds, in vitro culture tuber seeds, aerial tubers and consumption tubers. The second season tested with one treatment factor. The experimental design used was complete randomized block design with 3 replications. Results: The results showed that type of planting material that had the highest yield potential was aerial tubers of 17.1 t ha-1, then followed by in vitro culture of 15.3 t ha-1 and TSS of 9.9 t ha-1. Consumption tubers has the lowest yield potential of 7.2 t ha-1. Conclusion: To increase the productivity of shallots, planting material from aerial tubers can be used.
