Ñ  ABSTRACT   Ñ

    The effect of foliar spray with cycocel, Salicylic acid, and Silicon on Potato growth and yield, grown under salinity stress, was studied, at research center of Al- Hennadi, – Lattakia- Syria . The research concluded 14 treatments : 1-C , 2- SA 25, 3- SA50 , 4- CCC400 ,  5-CCC600,  6-Si 100 , 7- Si 200, 8-S, 9 –S+SA25 , 10- S+SA50, 11-S+ CCC400 , 12- S+ CCC600, 13- S+ Si 100, 14- S+ Si 200.

     The results showed that foliar spray with Si, CCC and SA, reduced the negative effect of salinity, and enhanced inter, leaf area/ plant (cm²)and leaf area index, and fruitful growth in terms of number and weight of tubers and yield when plants were irrigated with normal or saline water.

The results also showed that foliar spray with Si200 was significantly superior in all fruit growth indicators and gave the highest amount of total production.

     The results indicated that SA, CCC, and Si could alleviate the harmful effect of salinity, with preference of Si which was more effective.
