Vetiver grass was harvested at 4, 6 and 8-week old re-growth. The chemical composition and quantitative analyses of anti-nutritional components were determined. The result showed that dry matter and fiber content increased with age while crude protein, mineral content and anti-nutritional components reduced with age. It was concluded that age of re-growth significantly affect the nutrient and a...

The lead (Pb)/zinc (Zn) tailings contained high concentrations of heavy metals (total Pb, Zn, Cu and Cd concentrations 4164, 4377, 35 and 32 mg kg(-1), respectively), and low contents of major nutrient elements (N, P, and K) and organic matter. A field trial was conducted to compare growth performance, metal accumulation of Vetiver (Vetiveria zizanioides) and two legume species (Sesbania rostra...

Vetiveria zizanioides and Cyperus alternifolius were measured for their ability to decontaminate pig farm wastewater in 50_38.5_23 cm (L_W_H) plastic boxes. These plants were grown in pig farm wastewater with CODCr at 825 mg/L, BOD5 at 500 mg/L, NH3-N at 130 mg/L and TP 23 at mg/L, C. alternifolius and V. zizanioides could cut down those index to 64%, 68%, 20% and 18% respectively by hydraulic ...

Many studies have documented that patterns of species composition change after gap creation, but few have addressed the processes responsible for this change. The idea of competitive reduction, that disturbance removes biomass, reducing competitive intensity and allowing competitively inferior fugitive species to colonize, has been widely accepted but rarely tested. We suggest an alternative hy...

In order to facilitate transportation and accelerate growth, roots of Vetiveria zizanioides must be pruned before transplanting. The present research is aimed to investigate the best root length for vetiver grown in cadmium (Cd) polluted soil. The results indicated that 6 cm root-length plant (RLP) was the best candidate in phytoremediation of Cd-contaminated soil for its stronger tolerance and...

Vetiver [Chrysopogon zizanioides (L.) Roberty syn. Vetiveria zizanioides (L.) Nash] commonly known as khas-khas, khas, khus-khus or khus grass belongs to the family Poaceae. The roots of this grass on steam distillation yield an essential oil mainly consisting of sesquiterpenes (3-4 %), sesquiterpenols (18-25 %) and sesquiterpenones (7-8 %). Among these, the major economically important active ...

Free radicals induce numerous diseases by lipid peroxidation and DNA damage. It has been reported that some of the extracts from plants possess antioxidant properties capable of scavenging free radicals in vivo. Vetiveria zizanioides belonging to the family Gramineae, is a densely tufted grass which is widely used as a traditional plant for aromatherapy, to relieve stress, anxiety, nervous tens...

Recent studies show that Vetiver grass, (Vetiveria zizanioides (L.) Nash), may have potential as a dead-end trap crop in an overall habitat management strategy for the spotted stem borer, Chilo partellus (Swinhoe) (Lepidoptera: Crambidae). Vetiver grass is highly preferred for oviposition, in spite of the fact that larval survival is extremely low on this grass. The oviposition behaviour of fem...

Vetiveria zizaniodes (vetiver) is commonly known for its effectiveness in soil and sediment erosion control. It can tolerate to extreme soil conditions and produce a high biomass even growing in contaminated areas. Zea mays (maize) can also produce a very high biomass with a fast growth rate and possesses some degree of metal tolerance. A greenhouse study was conducted to investigate the feasib...
