      Abstract
      Sorgum (Sorghum bicolor L.) memiliki potensi besar sebagai sumber pakan karena mampu tumbuh pada lahan marginal dan memiliki kemampuan ratun. Namun, rendahnya kesuburan tanah menjadi kendala dalam meningkatkan produksi tanaman. Penelitian ini bertujuan mengevaluasi penggunaan pupuk organik granul berbasis mikoriza dan lamtoro terhadap produksi biji sorgum varietas Samurai 1 ratun 1. Penelitian menggunakan Rancangan Acak Kelompok (RAK) pola faktorial dengan dua faktor, yaitu jenis pupuk (G: pupuk organik granul, GM: pupuk organik granul + mikoriza, GLM: pupuk organik granul + mikoriza + lamtoro) dan dosis pupuk (2; 3; dan 4 ton ha?¹) dengan empat ulangan. Parameter yang diamati meliputi kolonisasi akar, produksi malai, dan produksi biji. Hasil penelitian menunjukkan bahwa jenis pupuk maupun dosis berpengaruh sangat nyata (P<0,01) terhadap kolonisasi akar. Perlakuan terbaik ditunjukkan oleh GLM dengan hasil kolonisasi akar tertinggi sebesar 48,66% dan produksi biji tertinggi sebesar 1224 kg ha?¹. Peningkatan hasil tersebut didukung oleh peran mikoriza dalam meningkatkan penyerapan unsur hara dan penambahan lamtoro sebagai sumber bahan organik serta nitrogen yang mendukung fase generatif tanaman. Dapat disimpulkan perlakuan terbaik diperoleh pada pupuk organik granul yang diperkaya mikoriza dan lamtoro yang menghasilkan produksi malai dan biji tertinggi.
       
      Sorghum (Sorghum bicolor L.) has great potential as a feed resource due to its ability to grow on marginal lands and its ratooning capacity. However, low soil fertility remains a major constraint to productivity. This study evaluated the application of granular organic fertilizer enriched with mycorrhiza and leucaena on the grain yield of first-ratoon Samurai 1 sorghum. The experiment used a factorial Randomized Complete Block Design (RCBD) with two factors: fertilizer type (G: granular organic fertilizer, GM: granular organic fertilizer + mycorrhiza, and GLM: granular organic fertilizer + mycorrhiza + leucaena) and fertilizer dose (2, 3, and 4 t ha?¹), with four replications. Root colonization, panicle yield, and grain yield were measured. Fertilizer type and dose significantly affected (P<0.01) root colonization. The GLM treatment produced the highest root colonization (48.66%) and grain yield (1224 kg ha?¹). The yield increase was attributed to improved nutrient uptake by mycorrhiza and the addition of leucaena as a source of organic matter and nitrogen. In conclusion, the application of granular organic fertilizer enriched with mycorrhiza and leucaena was the best treatment, producing the highest panicle and grain yields.
