Abstract
ABSTRACT Field experiments were conducted to evaluate the performance of palmarosa (Cymbopogon martinii), lemongrass (Cymbopogon flexuosus), and jamrosa (Cymbopogon spp.) in normal soil and sodic soils. Of the species tested, Jamrosa was the most tolerant and lemongrass the least tolerant of the sodic environment. On average, a two to nine percent reduction in palmarosa essential oil yield and a 11 to 20 percent reduction in lemongrass essential oil yield were observed in sodic soils as compared with essential oil yields on normal soil. No significant influence of soil sodicity on herb and essential oil yield of jamrosa was noted. The quality of essential oil was not significantly affected by sodicity stress in any of the tested species.
