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 Lechang lead/zinc (Pb/Zn) mine and Dabao Shan copper (Cu) mine are located at the north of Guangdong Province in southern China. The residual tailings were permanently stored in tailings ponds which required revegetation to reduce their impact on the environment. A greenhouse study was conducted to evaluate the feasibility of using Vetiveria zizanioides (vetiver) and Phragmities australis (...

Background: Vetiver is a key ingredient for the perfume industry nowadays. However, with the constant and rapid changes of personal tastes, this appeal could vanish and this sector could decline quite quickly. New dissemination paths need to be found to tap this valuable resource. Methods: In this way, its potential use in cosmetics either as an active ingredient per se (with cosmeceutical sign...

A series of trials have been conducted to evaluate the efficacy of Vetiver growing under hydroponic conditions to treat motel effluent, which has been primary treated in septic tanks. Water quality results and management issues are of interest. The aim is to surface irrigate the motel gardens with the treated effluent in a sustainable way. This can be accomplished if excessive nitrogen does not...

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...

Vetiver, a native of India is known for its perfumery and medicinal value since ancient times, much before the world became familiar with rose scents. The annual world trade in vetiver oil is estimated to be around 250 tons, with Haiti, Indonesia (Java), China, India, Brazil, Japan being the main producers, and USA, Europe, India, and Japan being the main consumers. It is a gift of India t o mo...

Vetiver grass was harvested at 4, 6 and 8-week regrowth and were ensiled with cassava peels at ratio 60:40 and 100% without cassava peels. The quality and chemical composition of the silages were assessed. The silages along with fresh unensiled re-growths of vetiver grass were fed to WAD goats in a cafeteria method to determine the coefficient of preference of the diets. Results showed that ens...

Vetiver, a perennial C4 grass, has long been known for its multifarious uses in perfumery, medicine and environmental protection. Two distinct vetiver morphotypes have been identified in India, i.e., A. North Indian type characterized by thick and smooth fast growing roots that produce superior quality of laevorotatory oil; and B. South Indian type with more number of thin and hairy roots that ...

Land degradation is becoming one of the severest environmental issues in the world, especially in developing nations. Land degradation, usually accompanied by soil erosion, always results in a decrease or complete loss of land productivity, and produces on-site and off-site pollution to soil and water. The methods for land reclamation are various, including physical, chemical and biological. Th...
