3. UNIQUE CHARACTERISTICS OF VETIVER GRASS
(Paul Truong; Tran Tan Van; Elise Pinners, 2008)
a. Morphological characteristics:
• Dense and finely structured root system
• These roots have a mean tested tensile
strength of about 75 Mega Pascal (MPa),
which is equivalent to 1/6 of similar mild steel
reinforcement. It also offers a shear strength
increment of 39% at a depth of 0.5m (1.5 feet).
• Roots grow very fast
• Some varieties (like VS1) have a rooting depth
of 3-4 m, which can be achieved in the first year
itself
• Stiff and erect stems that can stand relatively
deep water flows
• Tenaciously binds the soil and is difficult to
dislodge
• Highly resistance to pests, diseases
• A dense hedge is formed when planted close
together acting as a very effective sediment
filter and water spreader.
• New shoots develop from the underground crown making vetiver resistant to
fire, frosts, traffic and heavy grazing pressure.
• New roots grow from nodes when buried by trapped sediment. Vetiver will
continue to grow up with the deposited silt eventually forming terraces, if
