Abstract

Adverse environmental circumstances in the Sistan plain, such as poor vegetation cover and dust, is common to the region. The aim of this study was to measure the growth parameters of Vetiver zizanioides in five different regions in Sistan plain in Iran. The plant variables of height and number of shoots were measured weekly as the plants were watered for all plant bases. The depth of rooting and increase in biomass were measured at the end of the study period. A total of 30 plant bases of V. zizanioides with three replications per treatment were planted at the beginning of March 2014 in the hyper arid region of Sistan plain. The establishment and development of the plant bases were monitored for six months. The data was analyzed in SPSS software using Duncan's test and one-way ANOVA in a completely randomized design. The results showed compatibility of planting V. zizanioides with the climatic conditions along the banks of Sistan river, along the drainage areas of the wastewater treat

Conclusion

The results of this study show optimal performance of the growth variables of Vetiveria zizonioides on agricultural land, along river banks and wastewater drainage margins. It was shown to be very effective for stabilization of soil and dust, fodder production and removal of drainage and wastewater treatment. The compatibility of Vetiver with specific climate of Sistan is a major finding of this research. This compatibility has not been previously been reported and provides a wider potential for growth in hyperarid areas.

Climatic characteristics of arid and semi-arid areas create delicate and fragile conditions along with the threat of erosion and desertification. Sistan has a hyperarid climate, lacks vegetation, and has been affected by drought and destructive climatic factors such as wind erosion. Restoration of vegetation can strongly reduce erosion and desertification in such an area.The selection of compatible plant species that are tolerant of desert conditions is essential to restore and create vegetation. Vetiver (Vetiver zizanioides L. Nash) has been newly classified as Chryspogon zizanioides L. Nash. It has been used for bioengineering for soil stabilization and other environmental protection purposes in recent years (Truong et al., 2010). It was originally developed by the World Bank for soil and water conservation in India in the mid-1980s (Truong et al., 2008). The World Bank promoted Vetiver grass technology as a type of environmental protection (Sabetan Fadaii et al., 2011). It has be
