Penelitian ini bertujuan untuk mengetahui karakteristik morfologi dan produksi biomassa sistem penanaman intercropping tanaman Brachiaria ruziziensis cv Kennedy dengan legum Centrosema pubescens pada regrowth pertama usia 45 hari. Penelitian ini dilakukan pada bulan Januari hingga Maret 2026 di lahan Hijauan Makanan Ternak dan Pastura dan Laboratorium Hijauan Makan Ternak dan Pastura, Fakultas Peternakan, Universitas Gadjah Mada. Penelitian menggunakan rancangan acak lengkap (RAL). Terdapat 3 ulangan masing-masing perlakuan dengan total plot berjumlah 9. Plot tanah yang digunakan berukuran 1 x 1,5 m². Variabel yang diamati yaitu karakteristik morfologi dan produksi biomassa. Karakteristik morfologi Brachiaria ruziziensis cv Kennedy yang diamati yaitu tinggi tanaman, panjang tanaman, dan jumlah tunas. Produksi biomassa yang diamati terdiri dari produksi segar, produksi bahan kering, dan produksi bahan organik. Data dianalis dengan analisis independent sample T-test. Hasil penelitian menunjukkan bahwa tidak terdapat perbedaan nyata antara Brachiaria ruziziensis cv Kennedy dengan sistem penanaman monocropping dan intercropping pada data tinggi (100,04±11,05 ; 108,33±6,50) cm, panjang (119,85±4,17 ; 120,44±10,86 ) cm, Tunas (60,88±19,59 ; 89,22±9,57) cm, BK (5,41±0,65 ; 5,74±1,55) ton/ha, BO (4,78±0,53 ; 5,01±0,13) ton/ha, Segar (41,69±3,96 ; 44,50±0,50) ton/ha. Berdasarkan hasil penelitian dapat disimpulkan bahwa sistem penanaman intercropping dan monocropping menghasilkan produktivitas yang sama dan memberikan keuntungan terhadap komposisi vegetasi tanaman. 

This study aims to determine the morphological characteristics and biomass production of an intercropping system of Brachiaria ruziziensis cv Kennedy and the legume Centrosema pubescens at the first regrowth phase at 45 days. The study was conducted from January to March 2026 at the Forage and Pasture Research Station and the Forage and Pasture Laboratory, Faculty of Animal Science, Gadjah Mada University. A completely randomized design (CRD) was used. There were 3 replicates for each treatment, resulting in a total of 9 plots. The plots used measured 1 × 1,5 m². The observed variables were morphology characteristics and biomass production. The morphology characteristics of Brachiaria ruziziensis cv Kennedy observed were plant height, plant length, and number of shoots. Biomass production consists of fresh production, dry matter production, and organic matter production. The data were analyzed using an independent samples t-test. The results showed that there were no significant differences between Brachiaria ruziziensis cv Kennedy grown under monocropping and intercropping systems in terms of plant height (100,04 ± 11,05 ; 108,33 ± 6,50) cm, plant length (119,85 ± 4,17 ; 120,44 ± 10,86) cm, shoots (60,88 ± 19,59 ; 89,22 ± 9,57) cm, dry matter yield (5,41 ± 0,65 ; 5,74 ± 1,55) metric tons/ha, fresh matter yield (4,78 ± 0,53 ; 5,01 ± 0,13) metric tons/ha, Fresh (41,69 ± 3,96 ; 44,50 ± 0,50) metric tons/ha. Based on this study, it can be concluded that the intercropping and monocropping systems yield similar productivity and provide benefits in terms of composition.
