Lobak putih (Raphanus sativus) merupakan sayuran kaya nutrisi yang berpotensi meningkatkan kesehatan masyarakat. Namun, produktivitasnya di Kabupaten Sintang masih rendah, salah satunya akibat kesuburan tanah yang kurang optimal karena dominasi tanah Podsolik Merah Kuning (PMK). Penelitian ini bertujuan untuk mengetahui pengaruh kombinasi pupuk hayati dan pupuk organik terhadap produktivitas tanaman lobak. Penelitian dilakukan secara eksperimen menggunakan Rancangan Kelompok Lengkap Teracak (RKLT) faktorial dengan dua faktor: pupuk hayati (0, 5, dan 10 g/m²) dan pupuk organik kompos kulit buah (1, 2, dan 3 kg/m²), masing-masing dengan tiga ulangan. Variabel terukur meliputi tinggi tanaman, bobot daun, panjang dan diameter umbi, serta bobot umbi. Hasil penelitian menunjukkan bahwa kombinasi aplikasi 10 g pupuk hayati dan 2 kg pupuk organik per meter persegi (H2P2) memberikan hasil terbaik pada sebagian besar parameter: tinggi tanaman, bobot daun, diameter umbi, dan bobot umbi tanaman-1. Sementara kombinasi 5 g pupuk hayati dan 2 kg pupuk organik (H1P2) menghasilkan panjang umbi tertinggi. Temuan ini menunjukkan bahwa integrasi pupuk hayati dan organik secara signifikan meningkatkan pertumbuhan dan hasil tanaman lobak. Strategi ini direkomendasikan sebagai solusi untuk meningkatkan produktivitas sayuran secara berkelanjutan di lahan marginal.
