This experiment included three factors: First, three plant spacing. Second, three levels of Nitrogen fertilizer. Third, three levels of Phosphorus fertilizer. The results showed that high levels of nitrogen and phosphors added to plant spacing 20*20 cm had caused increased in length stem flower, number of leaves, diameter of stem flower and vase life (50.86 cm, 9.18 leaves, 9.10mm, 7,92 day) respectively. While the middle level of nitrogen and high level of phosphors added to plant spacing 10*10cm caused a increase in weight of flower, weight of petals and diameter of flower (2.85 gm, 1.94 gm, 54.21 cm) respectively. While the middle level of nitrogen and high level of phosphors added to plant spacing 30*30cm caused a high number of flower (25.27) that significant increase for most treatment. The results showed that high levels of nitrogen and phosphors added to plant spacing 30*30 cm had caused high essential oil content (332.01) mg/100 gm because of a significant increase in contents salicylate, camphene, methyl benzoate and limonene (1684.20, 1162.80, 2886.85, 1701.05) μg/ 5 gm respectively.

This study was carried out at the lath house, belong to Hortieculture Department, College of Agriculture, University of Basrah, during the period from (November-April) 2007-2008 to investigate the effect of foliar fertization with N:P:K (20:20:20) on production of cut flowers and volitial oil yield of Carnation plant (Dianthus caryophyllus L.) Plant were spraued with NPK fertilizer at three levels (0-300-600) mg/L at monthly intervals for three subsequent months . Results showed that plants spraying with NPK at 600 mg/L gave a significant increase in flowering cut yield and caused a significant increase in the volitil oil yield and percentage.
