Abstract: 

 The research was studied of Al- Hennadi, – Lattakia, in the spring season of 2020, where The effect of foliar spray with cycocel, Salicylic acid, and Silicon on Potato morpholigicall characteristics, grown and prodactivity under conditions of irrigation water salinity (6 ds). /m). The research concluded 14 treatments : 1-control , 2- Salicylic Acid 25 ppm, 3- Salicylic Acid 50 ppm , 4- Cycocyl 400 ppm ,  5- Cycocyl 600 ppm,  6- Silicon 100 ppm , 7- Silicon 200 ppm, 8-Salt water, 9 –Salt water+ Salicylic Acid 25 ppm , 10- Salt water+ Salicylic Acid 50 ppm, 11-Salt water+ Cycocyl 400 ppm  , 12- Salt water+ Cycocyl 600 ppm, 13- Salt water+ Silicon 100 ppm, 14- Salt water+ Silicon 200 ppm. The results showed that foliar spray with Si and SA, improved growth in, plant height, shoot number , leaf number, leaf area/ plant (cm2)and leaf area index, and fruit growth in terms of number and weight of tubers and productivity, when plants were irrigated with normal or saline water. The results showed as well that CCC treatment reduced plant height, and increased shoot number when plant were  irrigated with normal water, but, when the plants were irrigated with saline water, CCC treatment increased leaf number, leaf area/ plant (cm2), leaf area index, shoot number, and fruitful growth in terms of number and weight of tubers and prodactivity. The results indicated that SA, CCC, and Si could alleviate the harmful effect of salinity, with preference of Si200 which was more effective.

Key words: Salinity, Silicon, Salicylic acid,  Cycocel, Potato.
