Abstract

The current research was carried out at the Hort. Dept., Fac. of Agric., Benha Univ., Egypt, throughout the 2019/2020 and 2020/2021 seasons. To investigate the impact of water regime i.e. (100, 70 and 50% of field capacity) on growth of Rosmarinus officinalisL. plant in the two seasons. The results revealed that differences treatments of field capacity increased the growth parameters of rosemary plant in the two seasons. The use of field capacity at 100% achieved the highest values on all studied parameters of vegetative growth and some chemical composition, except the total carbohydrates % in both seasons. On contrary, the use of 50% FC scored the best values for total carbohydrates % and essential oil productivity in both seasons. Consequently, it is preferable to treat rosemary plants with FC at 100% in order to achieve the highest levels of vegetative growth parameters. On the other hand, it is possible to treat rosemary plant with 50% FC to obtain the highest essential oil productivity.
