On the basis of the results the seeds were sown on 21 of May the seeds were germinated and developed faster. The highest plant (150.8 cm) and the largest number of branches per plant (10.1) was obtained from the plants were sown on 4 of April. There was no significant effect among 1000 seeds weight and essential oil content of different sowing dates. The largest seed yield (1864.3 Kg/ha) and essential oil yield (91.3 Kg/ha) was obtained from the seeds were sown on 4 of April. Anethole content were decreased from the plants were sown from 6 of March to 21 of June, the lowest amount (58.2%) was extracted from the plants were sown on 21 of June.
