Aplikasi Pengurangan Pupuk Anorganik Melalui Penggunaan Mikoriza Pada Tanaman Kedelai Edamame Di Fase Vegetatif (Glycine Max (L.) Merrill)

Abstrak

Edamame soybean plants (Glycine max (L.) Merrill) are native to Japan and are known as a source of high vegetable protein. Edamame has great potential to be developed because it has quite high productivity. One effort to maximize productivity is through balanced fertilization. Currently, the continuous use of inorganic fertilizers by farmers is still common, which can cause soil hardening and environmental damage. One alternative to reduce the use of inorganic fertilizers is to utilize mycorrhizal biofertilizers. The purpose of this study was to determine the role of mycorrhizal biofertilizers in reducing the use of inorganic fertilizers on edamame soybean plants. This research was conducted from July to October 2024, located in the Kebonsari agricultural land, Sumbersari District, Jember Regency, East Java Province. This study used a non-factorial Randomized Block Design (RAK) method. The treatments used were 6 treatments. With treatment M0: Without mycorrhiza + 100% NPK (Control), M1: 5 grams of mycorrhiza fertilizer/plant + 50% NPK (1 gram/plant), M2: 10 grams of mycorrhiza fertilizer/plant + 50% NPK (1 gram/plant), M3: 15 grams of mycorrhiza fertilizer/plant + 50% NPK (1 gram/plant), M4: 20 grams of mycorrhiza fertilizer/plant + 50% NPK (1 gram/plant), M5: 25 grams of mycorrhiza fertilizer/plant + 50% NPK (1 gram/plant). The results of this study indicate that the use of mycorrhiza fertilizer in the treatment M1: 5 grams of mycorrhiza fertilizer/plant + 50% NPK (1 gram/plant) affects the parameters of plant height, and number of branches
