Edamame plants are one of the food crops that have long been cultivated by the Indonesian farmers for their dietary needs as a source of plant-based protein. The beneficial content of edamame in improving nutrition has led to an increase in demand for edamame both domestically and internationally (exports). The high export demand is not matched by edamame production. One of the efforts to increase edamame plant production is the application of natural plant growth regulators (PGRs). Plant Growth Regulators (PGRs) are organic compounds that are not plant nutrients, active at low concentrations, capable of stimulating, inhibiting, or altering plant growth and development. This research was conducted to determine the effect of types of natural PGRs on the growth and production of edamame. This research method uses a Complete Randommized Blok Design (CRBD) with one factor, which is the type of natural PGR with 4 levels consisting of no PGR (control), 10% red onion extract, 10% coconut water extract, and 10% bean sprout extract, and was repeated 6 times. The parameters observed in this study were plant height, number of leaves, root length, plant wet weight, number of pods and chlorophyll content. The results of the study indicateshowed that the treatment of natural plant growth regulators has an effect on the vegetative growth parameters of edamame. The study concludes that the treatment of 10% onion extract gives the best effect on the growth of edamame
