Abstract: 

The experimental was carried out in (2019-2020) at three research stastions ( Barsheen, Zahid and Almokhtarya) to identify the influence of environmental regions and different growing stages ( green grow – flowering – fruit formation- full maturity ) on the essential oil percentage of ( T.vulgaris) plant . the statical analysis results showed out  that there was a significant variants between the studied factors that affect the essential oil percentage of ( T.vulgaris)  and the region (Barsheen station ) was the best significantly on average (3.18%) then Almokhtarya (3.02%) with out significant variants while Zahid station was the least at (2.22%) . also the full maturity stage was the best significantly with average (3.8%) then fruit formation stage (3.37%) and the green grow stage was the least (1.37%) .While the treatment (Barsheen- Full maturity) was the best significantly with average (6.5%) then (Almokhtarya- Fruit formation) and (Barsheen – green grow ) was the least (1.2%).  That certificate the eco flexibility of thymus vulgaris and the variants of oil yield within the different environmental factors of planting region beside the stage of collecting the economical part of plant.

Keywords : Thymus.Vulgaris, Environmental region, collecting stage, essential oil percentage.
