The field experiment was carried out on the Scientific-Experimental and Introductory Facility of the Department of Plant Growing at the AU – Plovdiv in the 2008-2011 period. The experiment was performed by means of a block method with four replications; experimental field area - 15 m2. The effect of four nitrogen - 0, 80, 120 и 160 kg/ha and five sowing - 150, 200, 250, 300 and 350 g.s./m2 rates on the coriander yield and yield components of the Marokan variety were determined. The analysis of the results showed that the experimental factors - nitrogen fertilization and sowing rate in combination with the meteorological conditions during the years of the study had a significant influence on the coriander yield and yield components of the Marokan variety. During the study period - 2008-2011 the maximum values of the coriander yield components - number of umbels per plant, seed-weight per plant 1,000-seed weight and the highest seed yield - 2,492 kg/ha was recorded for the incorporation of 120 kg N /ha and sowing rate of 250 g.s./m2, while the lowest ones were for the variant without nitrogen fertilization and sowing rate of 150 g.s./m2. The most suitable nitrogen rate for the Marokan variety of coriander – 120 kg/ha and the most effective sowing rate of 250 g.s./m2 is recommended for the Plovdiv region.
