Abstract: 

The research was carried out at Al-Hanadi Research Station – Agricultural Scientific Research Center in Lattakia during 2022-2023 season to study the effect of silicon (potassium silicate) addition as a fertilizer for cabbage plants at two levels (25 kg/dunum and 50 kg/dunum) in treatments (T5 and T6), silicate fertilization with mineral fertilization in treatments (3 and 4), mineral fertilization (T2) and treatment without fertilization control treatment (T1). The Randomized Complete Block system was used in the experimental design. The results showed that the combined silicate and mineral fertilization had a clear positive effect on the growth of local cabbage plants. Cabbage leaves outperformed in the silicate and mineral fertilization treatment with the highest content of potassium (2.77%), phosphorus (0.325%), and total soluble sugars. This treatment also gave the highest yield of fresh cabbage 6.54 tons/dunum. While  the potassium silicate treatment increased the dry matter content of cabbage leaves to (13.07 and 13.04%) at the levels of 25 and 50 kg/acre, respectively.

Key words: Cabbage,potassium silicate, total soluble sugars, yield.
