Lemon grass (Cymbopogon flexuosus (Steud.) Wats. = Andropogon
nardus var. flexuosus Hack = Andropogon flexuosus Nees) is a
perennial grass, cultivated as an essential oil crop in Southern India,
Indonesia, and Madagascar. Two field
experiments were conducted in 2006 in Mississippi to evaluate lemon grass as an
essential oil crop for Mississippi. The
first experiment studied the effect of location (Poplarville, Stoneville, and
Verona), N (0, 80, 160, and 320 kg/ha) and S (0, 30, 60, and 90 kg/ha) on lemon
grass productivity and oil content and composition. The second experiment studied the effect of harvesting time and
soil type on oil productivity and quality.
Overall, lemon grass grew well in all three locations, but highest
yields were achieved in the most northern part of Mississippi (Verona). N fertilization increased yields, although
not linearly, while S application did not significantly increased yields. Oil content and composition varied depending
on location and N application. Although
the 2006 results are encouraging, more research is needed to complete the
evaluation of lemon grass as a new essential oil crop for Mississippi and
possibly other part of the Southern US.
