The present study was conducted during ( 2017-2018 and 2018-2019) seasons, at the Hort. Dept., Fac., of . Agric., Benha Univ., Egypt  to study the effect of chemical fertilizers (NPK) as a full dose and  biofertilization (Bio.) consisting of a mixture of (Nitrobein + Phosphorein) in the presence of Salicylic acid  ( SA) foliar spray at 150 ppm in a single or  combinations inbetween them on vegetative   growth ,grain yield ,chemical constituents parameters and oil productivity of coriander plants comparison with control plants  in both seasons. The results indicated that different treatments of  NPK mineral fertilizer, biofertilization and salicylic acid treatments , either alone or mixed among them, resulted in a significant increase in the growth ,chemical constituents parameters and oil productivity in both seasons. The use of  100% NPK   achieved the highest results in the characteristics of growth, yield and chemical composition, followed by the use of the treatment of  75%NPK  +Bio.+SA, where it achieved a significant maximize in this concern,whereas the treatment of  75% NPK + Bio. ranked the third in this context  as compared with untreated plants in both seasons. Also, the combined treatment of  75% NPK + Bio. + SA gave the highest values of oil productivity. Consequently, in order to achieve  the highest values of growth and chemical constituents ,it is preferable to treate coriander with NPK  at 100% or   75%NPK + Bio. + SA. Also, it is possible to treat coriander plant with 75% dose NPK +Bio. + SA to improve oil productivity.
