| 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 yield and berries quality of Superior grapevines grown in sandy soil. Berry setting, yield and both physical and chemical parameters of quality were remarkably improved due to using potassium silicate at 0.125 to 0.5% and/or selenium at 50 to 200 ppm compared to the control treatment. No considerable effect was observed on the investigated characteristics due to increasing potassium silicate concentrations from 0.25 to 0.5% and selenium from 100 to 200 ppm. The best results with regard to yield and berries quality of Superior grapevines grown under sandy soil conditions were observed due to treating the vines three times with a mixture of potassium silicate at 0.25% and selenium at 100 ppm. | ||
