Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND The almond industry requires new strategies to improve almond kernel quality. The use of biostimulants such as potassium silicate (KSi) is an eco‐friendly and non‐polluting alternative. The aim of this work was to investigate the preharvest application of KSi solutions at 2 and 20 mmol L−1 to ‘Peraleja’ almond trees during two ...
