ABSTRACT
An experiment was conducted to study effects of nitrogen fertilizer and plant density on quantitative relationships between yield and yield components and essential oil in cumin (Cuminum cyminum L.) under three different climate testing sites (cold, tropical and moderate climate locations) in western of Iran. Plant density (80, 120, 160 plant m-2) and Nitrogen fertilizer (0, 25, 50, 100 kg ha-1) were main and subsidiary factors respectively. Maximum yield (1275 kg ha-1) and essence (2.78%) were obtained at 100 kg nitrogen ha-1 and 160 plant m-2 in moderate location. Analysis of variance for testing contrasts of plant density and nitrogen fertilizer showed significant linear relationship between nitrogen fertilizer and yield components. A quadratic relation was found to be significant between nitrogen fertilizer and yield, yield components as well as between nitrogen fertilizer and essence percent. Significantly positive correlations were also observed between yield and number of seed per plant, number of umbel per plant, number of seed per umbel, thousand seed weight and biologic yield at tropical location. To gain maximum seed and essence of cumin, moderate location is recommended.
