A field study was conducted to evaluate the agronomic response of cumin (Cuminum cyminum L.) on the Harran Plain (Southeastern Anatolia, Turkey) to four seed rate (5, 10, 15, 20 kg ha-1) and two row spacing (15 cm and 30 cm), in the years of 2000-2003. The experiment was set up according to randomized complete block design with split plot. Seed yield, essential oil yield, essential oil ratio, 1000-seed weight, number of seed per umbel, number of branch per plant, number of umbel per plant and essential oil components ratio were significantly affected seed amount and inter row spacing. The treatment of 15 cm x 10 kg ha-1 in which the highest seed yield and essential oil yield were obtained, was found to be the most appropriate. Cuminaldehydewas determined the main component under all treatments and it was determined the highest values from the 15 cm row spacing and 10-15 kg ha-1 seed amounts.

Key words: Cumin (Cuminum cyminum L.), sowing rate, plant populations, seed yield, essential oil components
