This study was carried out in the Syrian coastal in Tartous governorate, during the growing season 2014, to study the effect of four plant densities (10.00, 13.33, 20.00, and 33.33) plant/m 2, and three levels of phosphate fertilizations (107.2, 160.8, 214.4 kg/ha of super phosphate P2O5 46%), besides the control, on quality traits (nitrogen, crude protein, phosphorus and potassium) of the coriander plant. The experiment was designed in a Randomized Complete Block design (RCBD) with a split plot arrangement of treatments with three replications for each treatment. The results revealed significant differences between treatments for most of studied traits, in addition to an interaction effect between plant density and fertilization. Although, the densities (10, 13.33 .20 plant /m 2) varied in their effect, but it significantly outperformed the highest density (33.33 plant/m2). The treatment 10 plants/m2 was more importance in terms of increasing the plant content of N, P, K. On the other hand, most of the measured characters were increased as a result of the increasing rates of phosphate fertilization. The treatment (160.8 kg/ha of P2O5) had a significant superiority upon on the rest of the treatments in terms of its effect on phosphor, nitrogen and crude protein, whereas the treatment )214.4 kg/ha (increased each of the content of the seeds of both of nitrogen and phosphor. The interaction effect between the highest plant density (33.33/m2) and the highest level of phosphor fertilization (214.4 kg/ha) had the superiority upon the other treatments in term of increasing each of seed content of P, N, protein, and K content of vegetative growth.

Key words: Coriander, Plant density, Phosphate fertilization, Vegetative growth, Seeds.
