Abstract
This study was carried out during 2014 and 2015 seasons to
examine the effect of spraying potassium silicate at 0.125 to 0.5% and/or
selenium at 50 to 200 ppm on growth and vine nutritional status of
Superior grapevines grown under sandy soil.
Treating the vines three times with potassium silicate at 0.125 to
0.5% and/or selenium at 50 to 200 ppm was very effective in stimulating
main shoot length, number of leaves/shoot, leaf area, wood ripening
coefficient, pruning wood weight/vine and cane thickness, chlorophylls a
& b, total chlorophylls, total carotenoids, leaf total carbohydrates %, N, P,
K, Mg (as %), Zn, Mn and Fe (as ppm) of Superior grapevines over the
control treatment.
Carrying out three sprays of a mixture of potassium silicate at
0.25% and selenium at 100 ppm gave the best results with regard to
growth and vine nutritional status of Superior grapevines grown under
sandy soil.
