Abstract: This research was conducted to determine suitable sowing dates and the potential productivity of coriander (Coriandrum sativumL.), grown in the Mardin, Denizli and Erzurum districts, at Tokat ecological conditions in 1997 and 1998 vegetation periods. Three local populations from Mardin, Denizli and Erzurum were sown on four different dates (1 November, 1 March, 15 March and 1 April). The highest seed yield was obtained from the Erzurum population as 908 kg/ha. The greatest essential oil ratio was recorded from the Denizli population with 0.39%. Linalool which is main component of coriander essential oil varied from 50.52- 92.52. Plant height (48.6-73.2 cm), number of branches per plant (4.5-6.2), number of umbels per plant (4.7-7.8), biological yield (2.282- 3.473 t/ha) and seed yield (0.678-0.911 t/ha) were decreased by later sowing dates . The effect of sowing dates was insignificant on 1000 seed weight (7.46-7.66 g), essential oil (0.28-0.33 %), protein ratio (14.1-14.8 %) and ash ratio (6.28-6.78 %).
Keywords: Coriander, Coriandrum sativum L., sowing dates, seed yield, essential oil, linalool.
