| Abstract | ||
| To study the effect of silica sources on some saline soil properties and sugar beet productivity and quality grown under saline soil conditions, a field experiment was conducted in Village El-Rowad in Sahl El-Hussinia, El-Sharkia Governorate, Egypt. Sugar beet (Beta vulgaris L var. Loil) was cultivated in the winter of two successive seasons (2022/23 and 2023/24). The results showed that a slight decrease in soil pH was observed with the higher silicate application rate (6 ml L-1), in the form of calcium silicate. The least value of soil EC (3.78 dS m-1) was reached under the interaction of the highest silicon rate (6 ml L-1) and calcium silicate form, with superior efficacy in mitigating soil salinity. Data showed that calcium silicate had significantly enhanced soil macronutrient and micronutrient contents compared to other silica sources used. The application rate (6 ml L-1) resulted in the highest increases, from 9.90 to 26.09% for macronutrients N, P and from 11.18 to 20.58% for Fe, Mn, respectively, and 15.79% for Zn, compared to the control. Data also revealed that root nutrient contents, as macro and micro-nutrient concentrations, with calcium silicate source at a rate of 6 mlL-1, were maximized from 21.03 to 42.96%, while reduced Na⁺ was valued by 4.14%. Calcium silicate at 6 ml L-1 gave more root length, dry matter, and sugar beet yield with a 2.36% increase compared to the control. Potassium silicate enhanced root weight by 17.65%. Finally, calcium silicate at the highest rate (0.6 ml L-1) gave the best overall sugar beet quality parameters, the maximum sucrose yield (4.02 Mg fed⁻¹), which was a 75.5% relative increase compared with control (2.29 Mg fed-1); total chlorophyll relative increase 63.92% and stress mitigation as the lowest proline contents compared with control. | ||
