Abstract: 

 The research was conducted during 2019 in Tartous governorate, Beit Sheikh Yunus village.. to study the effect of nitrogen fertilization and Salicylic acid on some of the productive traits (number of flower/plant, fruit weight /plant, weight of 1000 fruit gr, fruit yield Kg/h, harvest index%) of Coriander plant Coriandrum sativum L(.with split plot with three replications. four nitrogen fertilization rates) N1=0 ،N2=60 ،N3=100، N4=140) kg/h   and three Salicylic acid  concentrations (S1=0، S2=20، S3=4) mlg/L were used .  The results showed yhat: the nitrogen fertilization rate (N3)achieved a significant superiority over the two rates(N1, N2) and non- significant superiority over the rate(N4)in all productive characteristics, also spraying with Salicylic acid (S3) gave a significant increase comparable with the other concentrations (S1,S2)in all the studied traits. The interaction between nitrogen fertilization rate (N3)and spraying with Salicylic acid (S3) gave the best values in all studied productive traits as the number of flower/plant reached (27.21) flower, fruit weight /plant (9.08) gr, weight of 1000 fruit (13.32) gr, fruit yield(900.36) Kg/h and harvest index(63.18)%.

Keywords: Nitrogen Fertilization, Salicylic acid, productive characteristics, Coriander.
