Rizobakteri penghasil Indole-3-Acetic Acid (IAA) berpotensi digunakan sebagai agen biostimulan tanaman padi untuk mendukung pertanian berkelanjutan. Penelitian ini bertujuan untuk menganalisis pengaruh rizobakteri penghasil IAA terhadap perkecambahan tanaman padi (Oryza sativa L.). Isolat rizobakteri penghasil IAA yang digunakan dalam penelitian ini telah diisolasi sebelumnya dengan kode KP2, KP6, KP9 dan KP14. Biji padi IR64 disterilisasi permukaannya dengan menggunakan larutan NaOCl 5%. Biji kemudian direndam dalam suspensi isolat dan dikecambahkan dalam petri dish steril. Analisis hasil penelitian dilakukan dengan menggunakan metode one-way analysis of variance (ANOVA) dan uji lanjut yaitu duncan’s multiple range test (DMRT). Hasil penelitian menunjukkan bahwa prosentase perkecambahan tertinggi adalah kelompok perlakuan KP6 yaitu 98,67 ± 1,15 %. Perlakuan dengan isolat KP2 memiliki pengaruh terbesar terhadap panjang tunas yaitu 5,76 ± 0,77 cm. Panjang tunas kecambah dengan perlakuan KP2 dan KP6 berbeda nyata terhadap kontrol. Ukuran panjang akar tertinggi adalah 9,49 ± 0,41 cm dengan perlakuan isolat KP9. Panjang total kecambah dan indeks vigor pada semua perlakuan berbeda nyata dibandingkan kontrol dengan nilai tertinggi berturut-turut yaitu 9,48 ± 0,33 cm dan 935 ± 74 pada kelompok perlakuan KP2. Kesimpulan penelitian ini adalah bahwa isolat rizobakteri penghasil IAA pada penelitian ini berpengaruh positif secara signifikan terhadap perkecambahan tanaman padi pada parameter panjang total dan indeks vigor kecambah padi.
