Shallots (Allium ascalonicum L.) are a strategic horticultural commodity in Indonesia that has high economic value and stable market demand. However, the decline in productivity in some areas, such as Gorontalo, is still a challenge due to soil degradation and improper fertilization. Environmentally friendly cultivation approaches such as the use of kasgot organic fertilizers and Plant Growth Promoting Rhizobacteria (PGPR) are potential alternative solutions. Kasgot, the result of bioconversion of organic waste by Black Soldier Fly (BSF) larvae, is rich in macro and micro nutrients that are able to improve soil structure and increase fertility. Meanwhile, PGPR is a rhizosphere bacteria that is able to fix nitrogen, dissolve phosphate, and produce growth hormones such as IAA that support optimal plant growth. This study aims to analyze the effectiveness of the combination of kasgot and PGPR on the growth and production of shallots based on the latest literature. The results of the study show that the integration of the two has the potential to improve input efficiency, improve soil quality, and increase crop yields sustainably, especially on marginal land such as Inceptisol soils.
