The experiment was conducted during two growing seasons (2018-2019 and 2019-2020) in a field belonging to tomato development project Al- Zubair / Directorate for Agriculture of Basrah. The experiment included 18 factorial treatments that are the interaction between two levels of magnetically treated water (Magnetic and without), spraying with three concentrations of silicon K2SiO3 (0, 2.5, and 3.5) ml.L-1 and liquid sulfur (Zolfast) (0 , 1 and 1.5) ml.L-1 on some chemical traits of cauliflower plant. It was conducted according to Split Split Plot Design by Randomized Complete Block Design (R.C.B.D) with three replicates, the least significant difference test (L.S.D) was used to compare the averages at a probability level of 0.05.

The magnetic water was given a significant increase in the silicon, sodium, and proline in both growing seasons, while the increase in chlorophyll content and sulfur percentage were excelled in the first season, but in the second season plants gave a significant increase in the percentage of nitrogen, phosphorous and potassium.

The silicon showed an increase in both growing seasons in the chlorophyll, nitrogen, phosphorous, potassium, sulfur, silicon but decreased in the percentage of sodium and proline content. As for the factor Zolfast, the result was similar to the silicon factor, except for potassium the increase was in the second season only. The interaction between the three factors had a significant increase in most traits in the study.
