Journal Article 2019 12 13 To investigate the effects of water deficit stress and bio and non-bio fertilizers on <em>Thymus Vulgaris</em>, a split plot experiment was conducted based on randomized complete block design with three replications in 2017 in Asgarya agricultural field in Yazd. The treatments included water tension: W<sub>1</sub>=7 (Control), W<sub>2</sub>=12 and W<sub>3</sub>=17 days irrigation intervals as the main factor and bio and non - bio fertilizers at five levels including B<sub>1</sub>= control (without fertilizer), B<sub>2</sub>= endo mycorrhiza (Glomus), B<sub>3</sub>= Azospirillum bacteria, B<sub>4</sub>= Pseudomonas bacteria and B<sub>5</sub>= chemical fertilizer (NPK) a sub – factors. Results showed that the highest flowering branches yield, a, b, and total chlorophylls and nitrogen and phosphorus elements were observed in 17 days of irrigation (W<sub>3</sub>). 12 days of irrigation treatment (W<sub>2</sub>) showed the highest potassium element rate. The highest a, b and chlorophylls and nitrogen were observed in Azospirillum treatment (B<sub>3</sub>). The highest total chlorophyll, phosphorus element, carotenoids and flavonoids were observed in Pseudomonas treatment (B<sub>4</sub>); the highest potassium element rate were obtained in mycorrhiza treatment (B<sub>2</sub>); the highest flowering branches yield were observed in NPK treatment (B<sub>5</sub>) and control (B<sub>1</sub>) treatment resulted in the highest anthocyanin To investigate the effects of water deficit stress and bio and non-bio fertilizers on <em>Thymus Vulgaris</em>, a split plot experiment was conducted based on randomized complete block design with three replications in 2017 in Asgarya agricultural field in Yazd.
