Effect of vermicompost, worm-bed leachate and arbuscular mycorrizal fungi on lemongrass ( Cymbopogon citratus (DC) Stapf.) growth and composition of its essential oil
The objective of this study was to investigate the effect of
vermicompost, worm-bed leachate (WBL) and Glomus mosseae , an
arbuscular mycorrhizal fungi (AMF), on growth of lemongrass (
Cymbopogon citratus (DC.) Stapf). A response surface methodology,
i.e. a three-level Box Benhen design with three repetitions and three
blocks, was applied to optimize biomass production, essential oil yield
and its composition. Application rates of Glomus mosseae were 0, 1 or 2
g plant-1, vermicompost 0, 5 or 10 g plant-1 and WBL 0, 10 and 20%. The
AMF had no significant effect on the variables tested, but vermicompost
had a significant effect on essential oil yield and WBL on essential
oil yield, myercene concentration and shoot dry weigh (p < 0.05). It
was found that lemongrass fertilized with 2.0 g G. mosseae, 5.0 g
vermicompost and 20% worm-bed leachate would yield 0.797% essential oil
of which 62.6% was citral
