本研究は、成長培地組成とNPK施肥が斜面安定化のためのベチバー（Chrysopogon zizanioides）の根系機械的性質、バイオマス蓄積、及び栄養成長に及ぼす影響を調査した。結果は、生育培地と施肥がバイオマス生産、根径、引張強度に有意に影響することを示した。最高バイオマス（178.33g）はT80P20N7.5で記録され、最大根径（1.47mm）と引張強度（21.9MPa）はT100P0N0で観察された。これらの結果は、バイオマス生産と機械的補強の間にトレードオフがあることを示唆する。

📄 Abstract（原文）
Landslides pose a significant natural hazard requiring cost-effective, sustainable mitigation strategies. Nature-based solutions utilizing vetiver (Chrysopogon zizanioides) demonstrate considerable potential due to its deep, dense root system, which enhances soil reinforcement. This study examines the effects of growth medium composition and NPK fertilization on the root mechanical properties, biomass accumulation, and vegetative growth of vetiver under controlled greenhouse conditions. The planting medium comprised landslide-affected soil mixed with compost in varying proportions, combined with different NPK fertilizer levels. Root tensile strength was measured to assess mechanical performance, while biomass and vegetative parameters were evaluated to determine growth responses. Results indicate that both growth medium composition and fertilization significantly influence biomass production, root diameter, and tensile strength. The highest biomass (178.33 g) was recorded under T80P20N7.5, while the greatest root diameter (1.47 mm) and tensile strength (21.9 MPa) were observed under T100P0N0. These outcomes suggest a trade-off between biomass production and mechanical reinforcement. Overall, optimizing soil amendments and nutrient inputs enhances vetiver’s bio-reinforcement capacity, supporting its application in sustainable slope stabilization and landslide mitigation.
