Penelitian ini bertujuan untuk menganalisis sinergisme antara inokulasi B japonicum  dan mikroba dan pelarut fosfat dan dosis optimum pada pertumbuhan dan hasil tanaman kedelai. Percobaan dilakukan di lahan Balai Penyuluhan Pertanian (BPP) Kecamatan Majalengka Kabupaten Majalengka Jawa Barat pada bulan Maret sampai dengan Juni 2021. Rancangan yang digunakan dalam Percobaan ini adalah Rancangan Acak Kelompok (RAK) dengan Pola Faktorial. Faktor pertama dosis inokulan B. japonicum (R) dan faktor kedua dosis Mikroba Pelarut Fosfat (P). Hasil penelitian menunjukkan bahwa Secara sinergis Inokulasi B. japonicum pada dosis 5 g kg-1 benih dan mikroba pelarut fosfat 50 kg ha-1 dapat meningkatkan jumlah nodula efektif sebesar 110,48% dan nisbah pupus akar sebesar 13,83%. Dosis Inokulasi B. japonicum 5 g kg-1 benih menurunkan jumlah nodula tidak efektif sebesar 46,54%, meningkatkan diameter nodula efektif sebesar 1,75%, meningkatkan indek luas daun sebesar 14,69%, meningkatkan jumlah polong sebesar 16,04%, menurunkan jumlah polong hampa sebesar 3,62%, meningkatkan bobot polong per tanaman sebesar 17,20%, meningkatkan bobot 100 biji sebesar 1,55%, meningkatkan bobot biji per tanaman sebesar 17,20%, dan meningkatkan bobot bibi per petak sebesar 16,99%. Dosis 150 kg ha-1 dapat meningkatkan diameter nodula efektif hingga 0,98%, menurunkan jumlah polong hampa 29,82%.
