Abstract

This study was carried out during 2015 and 2016 seasons to examine the
effect of spraying potassium silicate at 0.025 to 0.1% with or without the
application of selenium at 50 ppm on fruit splitting %, fruit coloration %, yield
and fruit quality of Manfalouty pomegranate trees grown in sandy soil. The trees
received three sprays of silicon and selenium at the first of March and at two
month intervals.
Using potassium silicate at 0.025 to 0.1% with or without selenium at 50
ppm was very effective in improving the leaf area, N, P, K, total chlorophylls in
the leaves, fruit retention%, gross and marketable yields and both physical and
chemical characteristics of the fruits. Fruit splitting, fruit peel weight%, fruit peel
thickness, total acidity% and total soluble tannins were remarkably reduced with
using silicon alone in combination with selenium.
The effect was depended on increasing concentrations of potassium
silicate. Increasing concentrations of potassium silicate from 0.05 to 0.1% had
negligible effect on the investigated parameters.
For controlling fruit splitting and improving fruit coloration %, yield and fruit
quality of Manfalouty pomegranate trees grown under sandy soil, it is suggested
to use a mixture of potassium silicate at 0.05% plus selenium at 50 ppm three
times at the first week of March and at two month intervals.
