Abstract:
The research was carried out in Abi Jarash farm at the Faculty of Agricultural Engineering at Damascus University during the year (2020/2021), the experiment aimed to study the effect of the composition of the growth medium and the concentration of the nutrient solution on some indicators of vegetative and root growth and the productivity of the essential oil of rosemary. Rosemary cuttings were grown in five soil media (witness), Peat moosine, Peat moosine: pumice (1:1) volume, Peat moosine: perlite (1:1) volume, hydroponic by deep flow technique (DFT), the plants were irrigated with Hoagland solution at two concentrations (0.5 X, 1X). The experiment was designed according to randomized complete blocks. The mean PEAT MOOS gave the best results and values for the vegetative growth parameters. Where the average vegetative fresh weight of the plant, when treated with Peat moos, increased by (106.57%) compared to the control (8.21 g), the water factor, Peat moos: pumice, achieved a significant superiority over the rest of the treatments (without recording any differences between them) in the indicator A roots that reached Where they reached (28.22, 31.36), respectively, then, when you earn, his assets, his profits, his profits. The productivity of the essential oil in the Peat moos medium increased by (76.39) compared to the control (4.66). The hydroponics technique recorded a significant superiority with respect to root wet weight, achieving an increase of (771.02) % compared to the rest of the treatments. Focus on concentration for all key indicators (vegetative, root, productivity).
Keywords: Peat moos, mixture, deep flow technique, Hoagland solution, essential oil.
