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 (0107.2،160.8، and 214.4 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 (10، 13.33 and 20 plant/m2) varied in their effect، they had superiority upon the control(33،33)plant/m2، and the density 10 plant/m2 had more important effect in terms of increasing each of: branches number/plant، seed weight/plant، seeds number/inflorescence، protein content in plants and seeds and beta carotene and chlorophyll. However، the level 160.8k.g/h of P2O5 increased the number of inflorescences/plant، number of fruits/plant and seed weight/ inflorescence.

نفذ البحث خلال الموسم الزراعي (2014) م في الساحل السوري في محافظة طرطوس لدراسة تأثير أربع كثافات نباتية وثلاث مستويات من الأسمدة
The research was conducted during the agricultural seasons 2016,2017 m in the Syrian coast in Tartous governorate, the village of Beit Sheikh Yunus. To study the effect of organic and chemical fertilization on some productive traits (number of flow er/plant, fruit weight /plant, weight of 1000 fruit gr, fruit yield Kg/h, harvest index%) of Coriander plant.
The experimental was carried out to estimation the influence of competitive irrigation, organic, and chemical fertilization treatments as well as the interaction of them on coriander plant (Coriandrum sativum L.) by FRCBD in three replications.
The experimental was carried out to estimation the influence of competitive irrigation organic , and chemical fertilization treatments as well as the interaction of them on coriander plant ( coriandrum sativum L. ) during season ( 2011-2012) in Faculty of Agriculture Fields, Damascus University by FRCBD in three replications
The study was carried out at Abo Jarash farm, Faculty of Agriculture, Damascus University, during the growing season of 2012, where the maize cultivar "Gouta 1" was grown in three agricultural spacings (20, 30 and 40 cm between plants in the same row), with a fixed space (70 cm) between rows, according to the randomized complete block design and three replicates per treatment, in order to study the effect of the studied agricultural spacing on the following characters: plant height, length and weight of ear, number of kernel rows per ear, number and weight of kernels per ear, net percentage, hundred kernels weight, the kernel yield, the dry yield and the oil and protein contents in the kernels. Results showed a significant decrease in plant height from 155.31 to 130.10 cm, while a significant increase was observed in number of kernels per ear (from 310.05 to 373.82 kernels), in weight of kernels per ear (from 41.20 to 65.17 g) and in net percentage (from 61.61 to 91.51 %), respectively with the increase of agricultural spacing from 20 to 40 cm. However, the increase in these characters didn’t substitute the small number of plants in the vast spacing compared with the narrow spacing, which is reflected in kernel yield per unit of area that amounted to 3.19 and 2.04 tons/ha, respectively.
