. Similarly, Simon et al. (1992) reported that moderate water stress imposed on sweet basil resulted in higher oil content and greater total oil yield. Furthermore, the authors indicated that water stress changed essential oil composition: water stress
( Raymer, 2001 ). Current canola varieties are essentially free of erucic acid and glucosinolates. The consumer demand and consumption of canola oil in the United States are increasing as a result of its lowest content of saturated fatty acids (5% to 8
are partitioned during the olive oil extraction process and removed with the wastewater separated from oil in the mill; since the water content in fruit from irrigated orchards is higher, there is more wastewater washing the PP out and consequently
). In 2002 and 2003, a representative sample of 3.5 kg per plot was taken to the laboratory for oil extraction and chemical analyses. All trees were sampled. Fruit water and oil content. Fruit water content was determined by desiccation at 105 °C
uses ( Eloff, 2001 ), the importance of S. birrea is underpinned by its diverse characteristics such as high levels of vitamin C and protein, quality stable oil, and the novel flavor of its fruit. The vitamin C content of S. birrea fruit juice is
( USDA NOSB, 1995 ). In all of these situations, nutrient availability and water limitation present management challenges and may have complex effects on essential oil production in medicinal plants. Ensuring an adequate N supply is a key challenge to
essential oil production is at flowering, when the oil content and preferred composition are the highest ( Topalov, 1962 ; Zheljazkov, 1998 ). Various basil species and cultivars provide essential oil with different compositions and aroma. The
. Depending on the species, cultivar, and environmental conditions, oil content in seeds of traditional camellia varieties can range between 24% and 50% with an average of ≈30% ( Huang et al., 2013 ). Some of the new Camellia oleifera cultivars can reach 53
harvested area of ≈32,076 ha ( USDA, NASS, Crop Report, 2007 ). The U.S. peppermint oil is considered of high quality and U.S. essential oil broker companies have dominated the peppermint essential oil market. The essential oil content and composition of
availability of the required amount of irrigation water, which is a scarce resource in many areas. In terms of crop management, DI strategies have demonstrated their feasibility for yield improvement in arid and semiarid areas ( Gómez-del-Campo et al., 2014
