Abstract:
The research was carried out in the Abi Jarash farm at the Faculty of Agricultural Engineering at Damascus University during the year (2020). The experiment aimed to study the effect of the composition of the growth medium and the concentration of Hoagland’s solution on some growth indicators of rosemary plants. Rosemary cuttings were cultivated in five soil media (witness), peat moss, peat moss: volcanic pumice (1:1), peat moss: perlite (1:1), hydroponic, where deep flow technique was used for hydroponic culture (DFT) and stereo poor boxes were used. For the other media, plants were irrigated with Hoagland’s solution at two concentrations (0.5X, 1X). The experiment was designed according to randomized complete blocks. The mean peat moss gave the best results and values for the vegetative growth parameters. Where the average of plant height values increased when treatment peat moss by (50.65%) compared to the control (15.93), the two treatments peat moss, peat moss: Perlite achieved significant superiority over the rest of the treatments (without recording any differences between them) in the indicator number of leaves, which reached (108.33, 107.05). Respectively. While the results showed that the mixture peat moss: volcanic Pumice recorded the lowest values in the studied indicators compared to the rest of the media. The number of leaves and the number of vegetative branches increased by (46.53, 65.93%), respectively, compared to the control (73.93, 8.76). The hydroponics technique recorded a significant superiority in the length of the main rootstock, achieving an increase of (63.75) % compared to the rest of the treatments. The experiment showed a significant superiority of Hoagland solution at half concentration for all studied indicators (vegetative, root).
Key words: peat moss, mixture, deep flow technique, Hoagland solution, rosemary.
