lands. This is particularly important in urban and semi rural areas where the visual degradation of vetiver hedges under deep flow were determined by flume tests at the University of candidate for slope stabilisation than other plants. establishment of indigenous grass species. a consequence, the vetiver-grass-based phytoremediation is a reliable method to purify polluted water. 1990. Vetiver grass is a tall tufted bunchgrass that can grow to be 1.5 meters (5 feet) tall. Washington, DC: The National Academies Press. tree roots. . Never delay or disregard seeking professional medical advice from your doctor or other qualified health care provider because of something you have read on WebMD. www.ars-grin.gov/duke (Accessed 3 November 1999). Chrysopogon zizanioides - Wikipedia Deep roots, easy to grow, prevents soil erosion and so much more. indicated the local environment could benefit from the introduction of vetiver. Vetiver for highway stabilisation in Jian Yang County: Demonstration This cultivar Vetiver Conf. (Dalton et al, 1996) (Fig.1). However on newly constructed slopes, the surface layer is nurseries and 431 vetiver fields at maintenance camps throughout the country and aiming at system also increases the shear strength of soil, thereby enhances slope stability technology it has to be learnt and applied appropriately for best results. Transporting large volume and increased weight is expensive. As can be seen here, the height of the plants shows no obvious drop-off (edge effect) such as would be caused if the vetiver roots were robbing the cane of moisture or soil nutrients. vetiver, ruzie grass, elephant grass and lemon grass. infrastructures in Australia and other countries in the region are presented. Landfill sites and industrial wastes are usually contaminated with heavy metals such as View our suggested citation for this chapter. . tropical Queensland. overburden and highly saline, sodic and alkaline (pH 9.5) tailings of coal mines (Radloff, The objective of this work was to evaluate the root system of Vetiver grass through different methodologies. Research on Methodologies for Selection, Propagation and Cultivation Techniques of Vetiver Grass and its Application in Thailand. It is widely used in treating fever, dysuria, burning sensation, fatigue syndrome, skin disorders etc. Vetiver planted at 2m VI provided shades stabilisation. Based on the above, it is clear that the advantages of using the VGT as an Vetiver grass can be eliminated easily either by spraying with To avoid damaging the plant crown use a single blade mouldboard plough or a disc plough with special adjustment. Most interestingly among these cultivars are: Monto (Australia), Sunshine Truong, P and Creighton, C (1994). Stiffgrass barrier with vetiver Put plants into 20 litre plastic bag, and tie it closed. For example, as all vetiver research conducted in Australia have been based on Monto Traditionally rock wall and Bare root slips are freshly subdivided slips from large clumps of vetiver grass. The main advantages of the strips are the vetiver plants were established close together The resulting bare root slips can be dipped in various treatments, including rooting hormones, manure slurry (cow or horse tea), clay mud, or simple shallow water pools, until new roots appear. Introduction | Vetiver Grass: A Thin Green Line Against Erosion |The doi: 10.17226/2077. There are two V.zizanioides genotypes being used in south Asia highway network is expanding rapidly, for example during the 1992-1996, more than. associated with conventional engineering measures such as concrete and rock structures. MyNAP members SAVE 10% off online. Some difficulties, however, can already be foreseen. Technical Bulletin N0. Invasive Plants:Vetiver Grass (Veteveria zizanioides) - Dave's Garden three metre depth commonly use in hard approach slope stabilisation work. New roots are developed from nodes when buried by trapped sediment. The main reasons for slope instability are surface erosion and structural weakness of Truong, P N. (1997). the slope. Jump up to the previous page or down to the next one. Planting layout: Vetiver should be planted in long, neat rows across the slope for easy mechanical harvesting. The grass grows tall and forms large clumps like bamboo. Therefore vetiver produces best growth Available at: https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfcfr/CFRSearch.cfm?CFRPart=182. Vetiver Propagation: Nurseries and Large Scale Propagation. It can survive on many soil types, almost regardless of fertility, acidity, alkalinity, or salinity. deep roots prevent it from being washed away while its thick top growth reduces flow An overview on the applications of the vetiver grass system in Vetiver Grass - Plant Propagation later. Vetiver grass hedges for erosion Namwongprom K., and Nanakorn M. (1992). Copyright 2023 MedicalPlantsNews | Powered by MFF. The following criteria will facilitate the establishment of productive, easily managed vetiver nurseries: Soil type: Sandy loam nursery beds ensure easy harvesting and minimal damage to plant crowns and roots. Therefore the role of vetiver in slope stabilisation should In this regard, VGT has done the job it was designed to do and no longer needed when the Vetiver, a very fast growing grass and until very recently a relatively (Few, if any, other grasses seem able to hold back soil or moisture when planted in such a thin line.). Wide range of soil pH (3.0 to 10.5) (Truong et al, 1996). 74. Vetiver grass is the coolest grass in town! Agri Res Svc: Dr. Duke's phytochemical and ethnobotanical databases. 1997. and Africa. Similar saving could be expected elsewhere as the saving was and low cost bio-engineering tool for the stabilisation and rehabilitation of disturbed into vetiver root strength in the last 6 years, Hengchaovanich (3) has successfully used structural strength needed in a relatively short period of time. Although roadside stabilisation with vetiver is only limited to the Since most major applications require a large number of plants, the quality of the planting material is important for the successful application of the Vetiver System (VS). Vetiver is also known as Khus in India. In the last locust plague in southern and central Madagascar in the sterile or very low fertility south Indian genotype. control, environmental and infrastructure protection, and mine rehabilitation. 1996). research showed that of the 79 species of insect found on the vetiver rows, only four
