“…Th ere has been a report on similar aromatic grass in the region (Igbokwe and Asumeng, 2007), but this report was on Cymbopogon citratus, a diff erent species. Our study demonstrated that lemongrass could be grown as an annual crop in the southeastern United States and may provide biomass yields similar to literature reports (Rao et al, 1998;Singh, 2001;Singh et al, 1997Singh et al, , 2009. Th e latter authors also found that lemongrass biomass yields increased linearly in response to increasing N rates (Singh, 2001;Singh et al, 1996) or reached optimal levels at 100 kg/ha of N (Singh et al, 1997;Rao et al, 1998).…”

Lemongrass [Cymbopogon flexuosus (Steud.) Wats, (syn. Andropogon nardus var. flexuosus Hack; A. flexuosus Nees)] is one of the most widely grown essential oil plants in the world. Field experiments were conducted at Verona and Poplarville, MS, to evaluate the effects of N (0, 40, 80, and 160 kg N/ha) and S (0, 30, 60, and 90 kg S/ha) on lemongrass biomass productivity, essential oil content, yield, and oil composition. Overall, the essential oil content varied within 0.35 to 0.6% of the dried biomass. The major constituents were geranial (25–53%), neral (20–45%), caryophyllene oxide (1.3–7.2%), and t‐caryophyllene (0.3–2.2%). Biomass yields at Verona ranged from 9486 to 19,375 kg/ha, while oil yields ranged from 30 to 139 kg/ha. Overall, dry weight yields increased with the application of 80 kg N/ha relative to the 0 kg N/ha and with 160 kg of N/ha relative to the 0 and 40 kg N/ha treatments. At Poplarville, biomass yields varied from 8036 to 12,593 kg/ha, while oil yields ranged from 23.5 to 89.5 kg/ha. The application of N at 160 kg/ha at Poplarville increased dry weight yields relative to the N at 0 or 40 kg/ha rates, irrespective of the rate used for S. At Verona, within each S application rate, biomass yields were highest in Harvest 2, lower in Harvest 1, and the lowest in Harvest 3 (regrowth). The combined biomass yields of Harvest 1 and Harvest 3 would be lower, but oil yields would be higher compared to Harvest 2 (single‐harvest system). Lemongrass can be grown as an annual essential oil crop in the southeastern United States, with a potential for dual utilization: essential oil and lignocellulosic material for ethanol production.

“…Development of optimal leaf area is important for photosynthesis and production of dry herb yield (Jaleel et al 2009), because when leaf area is lower, the capacity to light trap decreases and this led to reduction in photosynthesis rate (Khalid 2006). Furthermore, the effect of reduced irrigation on growth of plant may be due to the lower availability of sufficient moisture in rhizosphere and the lower absorption of nutrients (Singh et al 1997). Indeed, in order to increase absorption of water, plants in water deficit conditions often reduce their biomass production and contribution more biomass to roots (Albouchi et al 2003).…”

In order to evaluate the effect of irrigation intervals and cattle manure levels on morphological traits, essential oil content and yield of oregano, an experiment was conducted at the experimental Farm of the Faculty of Agriculture, Urmia University, Iran. The experimental design was split-plots, arranged in randomized complete blocks with three replications. Main plots including irrigation intervals (1, 2 and 3 weeks) and four levels of cattle manure at 0, 10, 20 and 30 t ha -1 were allocated to sub plots. Our resultsshowed that increasing irrigation intervals reduced values of all morphological traits except for proportion of stems. Also, values for stems number, plant spread, stem diameter, leaf area, fresh and dry herb yield increased by increasing cattle manure levels. On the other hand, morphological traits not influenced by interaction of treatments except for plant spread and leaf area. The highest essential oil content (2.07%) and yield (66.62 kg ha -1 ) obtained in highest irrigation intervals and cattle manure levels. Whereas, 1 week irrigation interval without use of cattle manure produce lowest essential oil content (1.55%). For essential oil yield, the lowest value (46.37 kg ha -1 ) was found in 2 weeks irrigation interval with application of 20 t ha -1 cattle manure.

“…[29] The clear positive impact of adequate water irrigation amount on herbal fresh yield may be due to the availability of adequate moisture around the root rhizosphere and therefore a greater proliferation of root biomass resulting in the higher absorption of nutrients and water that lead to production of higher vegetative growth. [30] In our study, the reduction in growth and yield with increasing water stress might be related to a reduction in photosynthesis as a result of limitation in stomatal and mesophyll conductance. Drought stress is linked to stomatal closure and therefore low CO 2 fixation and reduction in photosynthetic activities.…”

A greenhouse experiment was conducted to study the effects of four irrigation intervals (4, 8, 12, and 16 days) and six harvests (2, 4, 6, 8, 10, and 12 months after transplanting) on biomass, essential oil content, and composition of Plectranthus amboinicus (Lour.) Spreng. Fresh weight and essential oil yield decreased with increasing irrigation interval; whereas, essential oil content was stimulated by water stress and increased as the irrigation interval increased. Fresh weight of Plectranthus amboinicus irrigated every 4 days peaked when harvested at 6 months, but essential oil content peaked when irrigated every 16 days and harvested at 2 months after transplantation. On the other hand, essential oil yield peaked when irrigated every 8 days and harvested at 6 months. Thymol, p-cymene, γ-terpinene, and β-caryophyllene were the major compounds, and they peaked at different irrigation intervals and harvest times. This study showed biomass, essential oil content, and yield as well as the major and minor constituents of Plectranthus amboinicus are influenced by irrigation interval and the timing of harvest.
