Abstract
Objectives:The research aimed to study the effect of three irrigation intervals (7, 15 and 21 days) and different levels foliar sprays of micronutrients individual also mixture and their interaction on vegetative growth, yield, essential oil production of Rosmarinus officinalis, L.Methods & Results: This current experiment was carried out during the Mansoura Horticulture Research Station.That planted seedlings of the plant in bags with a diameter of 50 cm and weighs 15 kg with a mixture of soil and the use of irrigation intervals and foliar sprays of micronutrients.1.Irrigation plants every 7 days significantly increased growth parameters in all vegetative growth characteristics and increased essential oil content / plant while Irrigation interval every 21 days increased essential oil percentage.2.Spraying rosemary herb with micronutrients mixture or individual at 150mixture increased significantly the measurements of vegetative growth characters, essential oil production.3.Irrigation plants every 7 days and Spraying rosemary herb with micronutrients mixture or individual at 150 ppm gave the highest values of measurement of vegetative growth and increased essential oil content / plant.Conclusion:It could be concluded that the best vegetative growth and the highest essential oil productivity were obtained from the interaction between irrigation every 7 days and foliar spraying with mixture or individual at 150 ppm of each.
