Pengaruh Jarak Tanam terhadap Nilai Nutrien Sorgum (Sorghum Bicolor (L.) Moench) sebagai Pakan Ternak di Kabupaten Bondowoso

Abstract

Sorghum is a potential cereal crop as forage. This study aimed to analyze the effect of different row spacing on the nutrient value of sorghum forage as fodder for livestock in Bondowoso District. Complete randomized block design (CRBD) was applied to 4 treatments and 4 replications. The row spacing treatment consisted of 20 x 60 cm (P0), 20 x 45 cm (P1), 20 x 30 cm (P2), and 20 x 15 cm (P3). Sorghum was planted in 4 m square treatment plots and harvested at 60 days. after sowing. Dry matter, crude protein, crude fiber, crude fat, ash content, Nitrogen Free Extract (NFE), and Total Digestible Nutrient (TDN) were the observed nutrient value parameters. Differences in row spacing produced sorghum forage (P<0,05) with dry matter (18%), crude fat (2-3%), ash content (7.5%), and NFE (69%). Increased row spacing density produced sorghum forage with lower crude protein (P<0,05). Furthermore increased row spacing density produced sorghum forage with higher fiber content (P<0,05). The highest TDN (P<0,05) was produced by the P0 treatment (62.77%). Different plant spacing did not immediately affect the nutrient value of sorghum forage. Narrow row spacing are applicable to cultivating sorghum forage as fodder.
