| Title : | FIBER YIELD OF TWO KENAF CULTIVARS (HIBISCUS CANNABINUS L.) UNDER DIFFERENT N-FERTILIZATION LEVELS AND DEVELOPMENT STAGES |
| Abstract : | Kenaf (Hibiscus cannabinus L.) is an important fiber crop with applications in textile and composite industries. This study aimed to evaluate the bast fiber and core wood productivity of two kenaf cultivars under different nitrogen fertilization levels at various developmental stages. A split-plot field experiment was conducted in Magnesia, Greece, during the 2023 growing season. Two kenaf cultivars (NH1 and MS8234) were grown under three nitrogen fertilization levels (N0: 0 kg N ha-1, N75: 75 kg N ha-1, N150: 150 kg N ha-1). Destructive sampling was performed at three developmental stages: pre-flowering, flowering, and maturity/harvest. Bast fiber separation was achieved using pectinase enzyme treatment, followed by manual separation and dry weight determination. Bast fiber percentage ranged from 35% at early stages to 30% at maturity, with core wood comprising the remainder. No significant differences in bast fiber-to-core wood ratios were observed between cultivars or fertilization treatments. However, total bast fiber and core wood productivity differed significantly between cultivars, with NH1 producing higher yields (5 Mg ha-1 fibers, 12.3 Mg ha-1 core wood) compared to MS8234 (3.6 Mg ha-1 fibers, 8.4 Mg ha-1 core wood) at harvest. Fertilization significantly increased total biomass production, with fertilized treatments yielding approximately 17.1 Mg ha-1 compared to 11.4 Mg ha-1 for unfertilized controls. The relationship between stem diameter and fiber percentage was weak, (R² = 0.18), and was not statistically significant. |
