      Abstract
      Brachiaria brizantha memiliki beberapa varietas antara lain B. brizantha var. brauna, B. brizantha var. ecotype b4, B. brizantha var. ecotype eth. 13726, B. brizantha var. ecotype eth. 1377, B. brizantha var. ecotype eth. 13809, B. brizantha var. marandu, B. brizantha var. mg4, B. brizantha var. paiaguas, B. brizantha var. piata, B. brizantha var. toledo dan B. brizantha var. xaraes. Penelitian ini bertujuan untuk menganalisis keragaman produktivitas dan kandungan nutrisi berbagai varietas Brachiaria brizantha, sehingga diketahui varietas yang memiliki pertumbuhan, produksi dan kualitasnya. Pada 30 peneliti dari tahun 2010-2020, terdapat 7 parameter yang diamati dan dicatat di Microsoft Excel 2010. Parameter tersebut meliputi data pertumbuhan, produksi dan kualitas nutrien, yaitu produksi tanaman, bahan kering (BK), protein kasar (PK), total digestible nutrient (TDN), neutral detergent fiber (NDF) dan acid detergent fiber (ADF). Kemudian data dianalisis menggunakan software Rgui. Hasil penelitian menunjukkan bahwa varietas Brachiaria brizantha berpengaruh nyata terhadap tinggi tanaman pada musim hujan (P<0,05) dan musim kemarau (P<0,01), produksi pada musim kemarau (P<0,01), BK pada musim kemarau (P<0,01), PK pada musim kemarau (P<0,01), TDN pada musim hujan (P<0,01), NDF pada musim hujan (P<0,01) dan musim kemarau (P<0,05), serta ADF pada musim hujan (P<0,01) dan musim kemarau (P<0,01). Pertumbuhan, produksi dan kandungan nutrien terbaik pada B. brizantha var. xaraes.
       
      Brachiaria brizantha has several varieties, including B. brizantha var. brauna, B. brizantha var. ecotype b4, B. brizantha var. ecotype eth. 13726, B. brizantha var. ecotype eth. 1377, B. brizantha var. ecotype eth. 13809, B. brizantha var. marandu, B. brizantha var. mg4, B. brizantha var. paiaguas, B. brizantha var. piata, B. brizantha var. toledo dan B. brizantha var. xaraes. This study aims to analyze the productivity and nutrient content of various varieties of Brachiaria brizantha. Within 30 studies from 2010-2020, production and quality parameters were observed and recorded in Microsoft Excel 2010. These parameters include data on growth, production and nutrient quality, namely plant production, dry matter (BK), crude protein (PK), total digestible nutrients (TDN) and neutral detergent fiber (NDF). Then data was analyzed using Rgui software. The results showed that the Brachiaria brizantha varieties had a significant effect on plant height rainy seasons (P<0.05) and dry seasons (P<0.01), production dry seasons (P<0.01), BK dry seasons (P<0.01), PK dry seasons (P<0.01), TDN rainy seasons (P<0.01), NDF rainy seasons (P<0.01) and dry seasons (P<0.05), and ADF rainy seasons (P<0.01) and dry seasons (P<0.01). The best growth, production and nutrient content were obtained by Brachiaria brizantha var. xaraes.
