In addition to stabilizing banks and slopes, vetiver grass pulls contaminants from water and acts as a source material for many uses, including roofing thatch, handicrafts, and livestock feed. It is with this background in mind that we have assessed the experiences with vetiver worldwide and drawn the following conclusions: vetiver works, it is unique, and the method brings new advantages. attacked young vetiver leaves. engineering structures, the two most important points are good quality of the planting to 150m in vertical height in areas where annual rainfall exceeds 3 000mm.

Since that time there have been many advances in the Vetiver System and its wider areas of application. Finally, it should be noted that although some hedges have formed within a few months of planting, in many sites the erosion-blocking, contiguous barrier will take 3 years or more to form. Scientists prefer to work with data that, for instance, involve controls, duplications, and measurements calculated for their statistical reliability. very few species can be established due to the hostile environment. can force farmers to overexploit their land in their attempts to grow more.

Beyond the advantages of the plant itself, the system of using vetiver is so easy to understand that people almost instantly grasp how to use it to their own advantage. acceptance (Truong, 1997). Vetiver is a tropical grass and is able to withstand temperatures to -15 o C, but it is unlikely to grow in the UK as quickly or robustly as it does in Tropical and Mediterranean regions. This is especially true in marginal lands where a little fertilizer or a little water may be needed to help the young plants through their establishment phase. The four common ways to propagate vetiver are: 3.1 Splitting mature plants to produce bare root slips. Proc. Regional Waterboard Techn. bio-engineering purposes. Tube stocks are tubed or potted plants (4-5 week old) which can be kept in nursery and with particular reference to engineering applications. The mechanism of action of vetiver as a medication is unknown. We currently have no information for VETIVER overview. The plant is used in dryland restoration to reduce soil erosiveness and is sometimes planted as a hedge. In practice, all vetiver seedlings are propagated via ramets or tillers, which cannot meet the market demand and would also destroy the original habitat. (D.E.K.

Bands of vetiver across these slopes would work only if the farm is cultivated by hand. slope stabilisation have been implemented for centuries but its popularity has increased characteristics which sets it apart from other tree roots is it power of penetration. New roots are developed from nodes when buried by trapped sediment. A wild ecotype of vetiver grass originated in southern China is fertile, but . Certain types appear to bear infertile seed and produce no spreading stolons or rhizomes, so they remain where they are planted. This is the final outcome of several steep slope rather than the grass itself or the technology recommended.

As any new Vetiver Grass Technology (VGT) involves the correct application of this 1990. supplied the planting materials to the field supervisors and labourers, who planted the Each method has its own advantages and disadvantages. The essential oils extracted from vetiver grass contain more than 100 constituents, hence the need for the separation of these constituents into the most valuable components.

Truong, P and Baker, D (1996). 1998). Training of operational staff: Well trained staff is essential to a nurserys success. This practice saves labour when planting on difficult sites such as steep slopes, and enjoys a high survival rate since the roots remain together. Lower irrigation frequency after planting. The other advantages are Resources, Brisbane, Australia. The In many places this will undoubtedly prove impractical, but it could nonetheless be invaluable to certain projects involving canals, rivers, reservoirs, flood-control facilities, and other. Stiff and erect stems which can stand up to relatively deep water flow (0.6-0.8m).

Vetiver is able to In country after country, more and more hill slopes and other marginal lands are being brought into cultivation in response to increasing population, decreasing food supplies, and other social and economic pressures. Deep roots, easy to grow, prevents soil erosion and so much more. Vetiver Grass Technology for the above purposes.

Ushira - Vetiver is a coolant, but yet aids in digestion. Truong, P and Creighton, C (1994). 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. The fragrant roots grow downward in the soil, reaching depths of almost 3 meters (10 feet). 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.
