The effects of nitrogen doses on the seed yield and some agronomic characteristics of coriander cultivars

This research was conducted to determine the effect of different nitrogen doses (0, 3, 6, 9, 12 kg N da-1) on the seed yield and some agronomic characteristics of Arslan and Gürbüz coriander cultivars. The experiment was designed in randomized split blocks design with four replications during 2011-2012 growing season in experimental field of Namık Kemal University. Result indicated that Arslan cultivar have higher values for number of umbels per plant, seed yield per plant, harvest index and 1000 seed weight, than Gürbüz cultivar. There were no statistically significant differences between cultivars for plant height, number of seed per umbels and seed yield per decare. When nitrogen doses increased, plant height and seed yield also increased. However, number of umbels per plant, number of seed per umbel, seed yield per plant and 1000 seed weight were not affected by increasing nitrogen doses.
