The development of the shallot commodity in Indonesia is excelent. This can be monitored by the consumption of shallots which continues to increase in line with the increase in population. Cultivation of shallots usually utilizes bulbs for planting material. This is because the use of bulbs is easier and more practical. Besides that, the success rate is high. This study aimed to (1) identify the best formula/dose of organic matter and mycorrhiza and the interactions between the two treatments in increasing shallot production on ultisols, (2) analyze the improvement of chemical properties of ultisols using soil enhancers, and (3) analyzing the increase in the production of mini bulb shallots using soil amendments. The study used several levels of factorial randomized block design (RBD) with mycorrhiza and organic fertilizer. Treatment 1 (Mycorrhiza), M0 = Control, M1 = 10 g/polybag, M2 = 20 g/polybag, M3 = 30 g/polybag, M4 = 40 g/polybag, and Treatment 2 (Organic Fertilizer), P0 = Control, P1 = organic fertilizer (0.6 kg/polybag), P2 = organic fertilizer (1.2 kg/polybag), P3 = organic fertilizer (1.8 kg/polybag), P4 = organic fertilizer (2.4 kg/polybag). The results showed that the interaction between mycorrhizal treatment and organic fertilizers had a significant effect. The highest yield on shallot plant height was in the M4P4 treatment, while the lowest was in the M3P0 treatment. The interaction between mycorrhizal treatment and organic fertilizers had a significant effect. The highest yield on the number of shallot leaves was in the M1P3 treatment, while the lowest was in the M3P0 treatment.
