Effect of magnatic water and sprying with silicon, zolfast on some growth and yeildes on cauliflower (Brassica oleracea L. var. botrytis)‎

الملخص EN

The experiment was conducted during tow growing season (2018-2019 and 2019-2020) in sandy clay soil in a field belonging to tomato development project Al-Zubair/ Directorate for Agriculture of Basra province.

The study aim effect of Magnetic water and foliar spraying with Silicon and Zolfast on growth and yield of cauliflower plant.

Its included 18 treatments, which consisted of the interaction between two levels of magnetization of irrigation water (Magnetic and without), spraying with three concentrations of silicon K2SiO3 (0, 1 and 1.5) ml.

L-1 and Zolfast (0, 2.5 and 3.5) ml.

L-1 by three sprays after 20 days of transplanting.

It was conducted as 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 results may be summarized as follows: The Magnetic water was gave a significant increase in the both season in the maturity time curd, but in the first season was significant at the curd diameter, weight of curd (500.2)g in addition the total yield (14.67) tons ha-1, but in the second season Magnetic water was significant in the plant height, number of leaves, leaf area, and the curd diameter.

Results showed that the spraying with Silicon gave a significant increase in all vegetative and yield traits under the experiment, the time of ripening curd, diameter of the curd, weight of curd (502.2, 567.1) g in addition the total yield (14.73, 16.64) tons.

ha-1 in the both season respectively.

Zolfast gave a significant increase in all vegetative and yield traits under the experiment the maturity time of curd, curd diameter, weight of curd (575.1, 602.2) g in addition total yield (16.87, 17.66) tons ha-1, in both season respectively.
