Lemongrass (Cymbopogon flexuosus) agronomic traits, oil yield and oil quality under different agro-ecological zones

Lemongrass (Cymbopogon flexuosus) growth rate, essential oil yield and composition as influenced by different soil conditioners under two watering regimes

“…For plants grown under rain-fed conditions, herbage yield was a high of 14,280 kg ha −1 in T4 and a low of 12,000 kg ha −1 in T3, while the plants grown under irrigated conditions had the highest yields of 12,120 kg ha −1 in T4 and the lowest yield of 9960 kg ha −1 in T2. These values are comparable to previously reported figures by Mwithiga et al [ 57 ] and Singh et al [ 40 ].…”

“…The major components of the C. flexuosus oil in the two harvests in this study included citral (75.97–87.70 %), geranyl acetate (0.8–4.91 %), geraniol (0.8–4.26 %), isogeranial (1.83–3.45 %) and isoneral (1.29–2.78 %), which is in line with previously published papers [ 11 , 14 , 57 , 59 , 62 ]. Other compounds were recorded in minimal quantity accounting for less than 0.8 %.…”

“…Oil content of plants grown under rain-fed conditions and harvested at 120 DAT varied markedly ( P = 0.006) from a low of 0.17 % in T3 treatments to a high of 0.23 % in T4 treatments. This is comparable to oil values of C. flexuosus ranging from 0.05 to 1.70 % and from 0.17 to 0.24 % reported in India [ 4 ] and in Kenya [ 57 ], respectively. Conversely, relatively higher values of C. flexuosus essential oil content under various soil nutrient management have been documented when compared to values of this study (0.17–0.23 %).…”

“…Cymbopogon species EO are used commercially in cosmetics, pharmaceuticals, aromatherapy, food, flavors, fragrances, perfumery, detergents, tobacco products (Mwithiga et al, 2022;Dangol et al, 2023) and insecticidal products (Zhang et al, 2011;Moustafa et al, 2021). The Cymbopogon genus is native to Asia, Africa, Australia and tropical islands and comprises 144 species.…”

“…The temporal and spatial variations in total content of secondary metabolites in plants occur due to alterations in gene expression and modifications resulted from the interaction of physiological, biochemical and environmental conditions (Li et al, 2020). Essential oil composition and concentration are influenced by genetic and environmental factors (Aboukhalid et al, 2017;Verma et al, 2020;Kaur et al, 2021;Mwithiga et al, 2022). Therefore, according to species, genotype, cultivation environment (Aboukhalid et al, 2017;Verma et al, 2020;Kaur et al, 2021;Mwithiga et al, 2022) and seasonality (Pinheiro et al, 2016), EO have a specific composition and concentration.…”
