Abstract


The lack of information about the cultivation of coriander plant in Syria prompted us to study the effect of four plant densities (33.33, 10, 13.33 and 20 plant/m2), and four levels of phosphate fertilization (0, 107.2, 160.8 and 214.4 k.g/ha of Superphosphate 46%) on some productive and quality traits of the coriander plant. This study was carried out in Tartous province during the growing season 2014, using Randomized Complete Block design with a Split Plot arrangement of treatments. The Results revealed that there were significant differences between the treatments for the whole traits, in addition to a significant interaction between density and phosphate fertilization. Although the densities (33.33, 20 and 13.33 plant/m2) varied in their effect, they had superiority upon the )10) plant/m2, and the density 33.33 plant/m2 had more important effect in terms of increasing each of: oil on leaf and fruits in plants. However, the level 214.4 k.g/ha P2O5 increased the oil in leafs plant and fruits.
