EFFECT OF MAGNETIC WATER AND FOLIAR APPLICATION OF (Zolfast) AND SILICON ON SOME CHEMICAL PARAMETERS

The experiment was carried out in a field belonging to the tomato development project Al- Zubair / Directorate for Agriculture of Basrah for two growing seasons (2018-2019 and 2019-2020). The experiment included 18 factorial treatments involving the interaction of 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 sulphur (Zolfast) (0, 1 and 1.5) ml.L-1 on some chemical traits of the cauliflower plant. It was carried out using the Split Split Plot Design using Randomized Complete Block Design (R.C.B.D) with three replicates, and the averages were compared using the least significant difference test (L.S.D) at a probability level of 0.05.

In both growing seasons, the magnetic water gave a significant increase in silicon, sodium, and proline, while the increase in chlorophyll content and sulphur percentage were exceeded in the first season, but plants gave a significant increase in nitrogen, phosphorous, and potassium percentage in the second season.

In both growth seasons, the silicon content increased in chlorophyll, nitrogen, phosphorus, potassium, sulphur, and silicon, but the percentage of sodium and proline content declined. The outcome for the Zolfast factor was comparable to that of the silicon factor, with the exception that potassium increased only in the second season. In the study, the interaction of the three factors resulted in a significant rise in most attributes.
