This research was carried out at Al Sanoubar Station, Scientific Agricultural Research Center in Lattakia, in order to study the effect of organic fertilizers in productivity of “Thymus vulgaris“, during the seasons 2016-2019. The experiment was designed in randomized block design at a rate of seven treatments and three replicates/ treatment; the treatments are : the control (T0), the farmer (T1),cattle manure fertilization (T2), poultry fertilization (T3), Mixed fertilizing (T4), faba bean (T5),vetch plant (T6). The results showed variability at the level (5%) and the superiority of the treatment (T4) in term of the average of plant length , the average number of branches/ plant, wet weight of plant (28cm, 15 branch/ plant 109 g) except (T6) with respect to number of branches plant(14) branch. The percentage of essential oil content was significantly increased in response to the use of poultry fertilization (T3) which realized higher percentage than the rest of the treatments by 8.4% followed by(T1) by 3.737%
Key words: Thymus vulgaris, organic fertilization, green fertilization, poultry, cattle manure.
