Abstract Shallot production in Indonesia is still relatively low. This is due to the use of shallot bulbs that are not sterile and susceptible to disease. One way to increase the production of shallots is by using botanical seeds (True Shallot Seed). The research aimed to evaluate the growth and yield of two varieties of TSS with the application of NPK and Magnesium fertilizers. The treatment was arranged in a randomized block design with three factors. The first factor was varieties, which consisted of Sanren F1 and Lokananta varieties. The second factor was the application of magnesium, which consisted of without magnesium, 125, and 250 kg Mg ha−1. The third factor was the application of NPK, which consisted without NPK, 83.3, 166.6, and 250 kg NPK ha−1. The results showed that the effect of varieties, NPK fertilizer, and Mg were significant differences in the parameters of the number of leaves 7.0, and the number of bulbs plants 2.7 where sanren showed better results. While the effect of varieties, NPK, and Mg fertilizers was significant differences in the parameters of plant height 41.5 cm, the Lokananta varieties showed better yields.
