Production Potential of Vetiver (Vetiveria zizanioides L.) as Affected by Different Planting Methods and Spacings

Abstract

Present study was undertaken to find out suitable planting method and spacing combination in order to enhance the biomass production, harvestable root yield and oil content of Vetiver. Experiment on production potential of Vetiver (Vetiveria zizanioides L.) under different planting methods was carried out using three different planting methods (Le. ridge and furrow system, planting pits and beds). It was followed a Randomized Complete Block Design with five replicates. Experiment on growth and production potential of Vetiver (Vetiveria zizanioides L.) under different spacing combinations was carried out in Two Way Parallel Row Design using fifteen different spacing combinations and four replicates. Results of these studies revealed that different planting methods as well as spacing combinations had significant impact on biomass production, un-harvestable root yield as well as oil yield of Vetiver. Significantly higher (P<0.05) growth and yield parameters were recorded in both ridge and furrow system followed by bed method with compared to pit method. Spacing of 80 x 60 cm2 resulted in significant (P<0.05) increase in all the growth and yield parameters. Thus, Vetiver planted in ridge and furrow system with 80 x 60 cm2 could be used to enhance biomass production, root oil content as well as harvestable root yield of Vetiver.
