Abstract

Kedelai (Glycine max L.) merupakan komoditas strategis penghasil protein nabati, namun produktivitasnya sering terhambat oleh defisiensi nitrogen. Penelitian ini bertujuan mengevaluasi pengaruh pemberian Rhizobium sp. terhadap pertumbuhan dan produktivitas kedelai varietas Dering. Percobaan menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan tiga perlakuan dosis Rhizobium (0 mg, 5 mg, dan 10 mg per tanaman) dan lima ulangan. Hasil menunjukkan bahwa dosis 5 mg meningkatkan tinggi tanaman secara signifikan (81,28 cm), sedangkan dosis 10 mg meningkatkan jumlah daun (23,8 helai), cabang (2,8 cabang), dan polong (38 polong per tanaman). Analisis statistik (ANOVA pada taraf signifikansi 5%) mengonfirmasi perbedaan nyata antar perlakuan. Simbiosis Rhizobium-kedelai efektif mendukung fiksasi nitrogen dan mengurangi ketergantungan pada pupuk anorganik. Dosis 10 mg direkomendasikan untuk produktivitas optimal.
