چکیده

Chrysanthemum is one of the five main cut flowers in Iran. Knowledge about the optimal range of macro-nutrientsespecially nitrogen (N), for the best quantitative and qualitative characteristics of chrysanthemum is of great importance. Randomized complete blocks design in three replications was implemented in this research. Five levels of N included 0, 75, 150, 225 and 300 kg/ha(ammonium nitrate) has been applied to chrysanthemum Bornacultivar in Mahalat city of Iran. The results showed that maximum crown diameter, flower longevity, chlorophyll index, fresh and dry weight of the plant were obtained at the level of 150 kg/ha, compared to the control. Also, the highest total absorption of macro-nutrients (nitrogen, phosphorus and potassium (NPK)), and micro-nutrients (iron, manganese, zinc and copper) was observed at the level of 150 kg/ha fertilization.According to the results, N application in the level 150 kg/hacan be recommendedto have best growth condition for the Borna cultivar of chrysanthemumin Mahalat city.
