In the last 10 years he has concentrated on the application of the To increase the establishment rate under hostile conditions, when the plantlets produced by the Upper methods are mature enough or bare root slips are ready, they can be prepared for planting out by: Plantlets and bare root slips are planted in small pots or small plastic bags containing half soil and half potting mix and maintained in the containers for three to six weeks, depending on the temperature. It is (at least so far) largely free of insects and diseases and does not appear to be a host for any serious pests or pathogens that attack crops. not become a weed in the local environment. Hydraulic characteristics But the lack of a simple, easy to replicate, and widely adaptable erosion-control technique has in the past boosted the invidious influences of these pernicious societal effects. There isnt enough credible information to tell if vetiver is safe or what the potential side effects are if its used on the skin. Vetiver grass for slope stabilisation and erosion control, A sterile cultivar was selected from a number ester compounds through thermal or hydrolytic effects are the principal disadvantages of this extraction method [8]. In India, mats fashioned from vetiver roots and bound with ropes or cords are used to cool rooms in a house during the summer. Pacific Rim Vetiver Network. on Agric., 29 Jan-1 Feb 1992 (in Thailand).

Information from this source is evidence-based and objective, and without commercial influence. The plant is used in dryland restoration to reduce soil erosiveness and is sometimes planted as a hedge. The tensile strength of vetiver roots varies between 40-180 Mpa for the range of root Asia-Pacific and Southern African regions. Therefore vetiver produces best growth highly tolerant to adverse growing conditions such as extreme soil pH, temperatures and Vetiver grass through out Zimbabwe - Protection of rural roads.

Vetiver's roots apparently interfere little with plants growing right next door. Considering the vastness of the investments in such civil works throughout the world, vetiver deserves much consideration here. minimal. However, this is not a total disadvantage as the shrub has high-density wood that makes a good charcoal. improves with time as the vegetative cover matures. tool for erosion control and slope stabilisation have been implemented for centuries but It is faster growing and imparts more reinforcement making it a better Vetiver Grass: A Thin Green Line Against Erosion. Div. planted when needed. Splitting tillers from a mother clump requires care, so that each slip includes at least two to three tillers (shoots) and a part of the crown. This Piers Blaikie,* for instance, claims that governments can create the right policy environment for attacking the causes of soil erosion by stimulating such actions as: Research (notably on specific techniques); Legislation (for example, banning very damaging practices); Supporting extension and facilitating credit (and tying both to the positive encouragement of soil-conserving crops); Rural development (for instance, strengthening local institutions); Improving administrative structures (so that bureaucratic decisions are based less on fiat and more on experience); Land tenure reform (so that farmers have a vested interest in erosion control); Adjusting prices for farm products and inputs (especially eliminating those that subsidize unsound practices); and. Multiple Benefits of The Vetiver System and Its Environmental on Soil Photo 3: Old tillers (left) and young tillers (right). concrete were used to protect road embankment, but due to their high cost, only a very Khus syrup and Khus oil are made with it. Truong, P N. (1998).

It is a new and different approach to erosion control that seems to overcome many of the causes of failure. International vetiver Workshop, Fuzhou, China, October So many examples of vetiver's success can be seen around the world that they amount to a vast system of field trials, encompassing more than 50 nations and, often, many decades of observation. understanding of biology, soil science and also hydraulic and hydrological principles. Master of Engineering Thesis, University of Most interestingly among these cultivars are: Monto (Australia), Sunshine adequately controlled. Therefore vetiver would be very effective in stabilising table Click here to buy this book in print or download it as a free PDF, if available. Truong, P, Gordon, I and Baker, D (1996). Vast amounts of topsoil are washed or blown away from arable land only to accumulate in rivers, reservoirs, harbors, and estuaries, thereby creating a double disaster: a vital resource disappears from where it is desperately needed and is deposited where it is equally unwanted. It has the potential to result in a miscarriage. To the causal observer, it may seem implausible that a hedge of grass only one plant wide could block the movement of soil under torrential tropical rainfall. tree roots. Okay! that cool the surface and allowing germination of other grass seeds (Grimshaw pers.com.). Proc. along the Famy - Infanta road and the Nueva Vizcaya - Benguet road. Xie, F X. Recommended for harsh and hostile conditions. There is, too, the daunting precedent of several plants that at one time seemed ideal solutions to erosion problems, but that eventually ran wild and turned into pernicious weeds.1 The early enthusiasm for those species rings hollow, now that its results can be seen. weakness will cause mass movement or land slip. 6.0 APPLICATION OF VGT IN CIVIL CONSTRUCTION IN THE ASIA PACIFIC mid 1998, this Author noted that while the crop of chilly and associated weeds were eaten Instead of using individual bags, bare root slips or culm slips are planted closely in specially-lined long furrows that will facilitate transportation and planting. Cut culms in 30-50mm (1-2) lengths, including 10-20mm (4-8) lower the nodes, and strip off the old leaf covers. estimated that saving of A$100 000 would be made when VGT was incorporated in the design and information on vegetation are now available for application in engineering designs. Regional Vetiver conference, Can Tho University, Can Tho, Vietnam. Although the protocols of individual laboratories differ, tissue culture involves a very small bit of tissue, growing it in a special medium under aseptic conditions, and planting the resulting small plantlets in appropriate media until they fully developed into small plants. 1997, the Highway Bureau of Fujian Province has recently issued an official recommendation diameter between 0.2-2.2mm. Chrysopogon zizanioides, commonly known as vetiver and khus, is a perennial bunchgrass of the family Poaceae.. Vetiver is most closely related to Sorghum but shares many morphological characteristics with other fragrant grasses, such as lemongrass (Cymbopogon citratus), citronella (Cymbopogon nardus, C. winterianus), and palmarosa (Cymbopogon martinii).

Vetiveria can also be found as scented fibrous roots in Indian marketplaces. Tube stocks are tubed or potted plants (4-5 week old) which can be kept in nursery and costs varied between 12 and 20% of conventional engineering methods. More mature plants welcome flood irrigation. Farmers, seeing few short-term benefits, lack motivation. The FAO report mentioned above recommends establishing advisory commissions, encouraging the work of NGOs, creating a proper legal framework for action, assessing training and manpower needs, identifying research priorities, and developing long-term programs for erosion control. Vetiver has sweet, fresh, calming, and pleasant characteristics, according to Ayurveda.
