Abstract
In order to combat the adverse effects of water stress on coriander plants grown in a semi-arid region, this study was undertaken during 2020 and 2021 seasons. Field experiments were conducted at the Experimental Farm of South Tahrir Research Station in El-Bustan area, El-Beheira Governorate, Agricultural Research Center, Egypt. The influence of different irrigation levels and boron foliar spray on the vegetative growth, yield and essential oil of coriander plant (Coriandrum sativum L.) grown in a sandy soil were investigated. The treatments comprised of four-drip irrigation levels (60, 80, 100 and 120%) of crop evapotranspiration (ETc) and four boron rates (0, 50, 100 and 150 ppm) in a split plot design with three replicates. The results revealed that both irrigation and boron foliar application significantly affected growth characteristics, yield and essential oil content of coriander plant. Maximum mean values of growth characteristics and fruit yield were achieved with the highest amount of irrigation water (120% ETc) which showed non-significant differences with the lower irrigation level (100% ETc). The least mean values of growth characteristics and yield parameters were obtained at an irrigation level of (60% ETc) in untreated boron application. The results showed that essential oil yield increased at moderate water stress (80% ETc) with boron foliar application at 150 ppm thereby improving fruit quality. The highest values of crop coefficient (Kc) of coriander were obtained in April with a mean value of 0.64 at the experimental site. The mean values of water consumptive use were 1201 m3/feddan during the growing season. Therefore, spraying boron at 150 ppm could serve as a promising approach under moderate water stress (80%) conditions to maximize coriander yield and quality in sandy soils
