Abstract

We investigated the kenaf plants (Hibiscus cannabinus. L) on the 50th day after planting. The experiments were carried out on a 200 m2 area in the hilly area of ​​Huong Tho commune, Hue City. The plants grew well, reaching a height of 118.41 cm. The fresh biomass and dry matter were 40.16 and 7.6 kg. The yield of fresh biomass and dry matter were 2.01 and 0.38 kg·m–2. The dry matter in stems and leaves was 18.93 and 18.07%. Crude protein, lipids, and minerals of dried leaves were higher than that of stems. Crude fibre, ADF, and NDF of stems were higher than that of leaves. Crude protein, lipids, and minerals in the dried stems and leaves were 8.81–28.03, 1.03–4.28, and 6.37–8.42%, respectively, whereas the percentage in the fresh was 1.66–5.07, 0.19–0.77, and 1.18–1.52%, respectively. Crude fibre, ADF, and NDF in stems and leaves by dry matter were 47.64–12.89, 51.49–16.36, and 65.55–23.91%, respectively, whereas the percentage of these components in the fresh matter was 9.04–2.32, 9.75–2.95, and 12.41–4.31%, respectively.
