Soil Silicon Application Alleviates Drought Stress in Sugar Beet (Beta vulgaris L.)

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background: The increasing frequency and intensity of drought events have led to yield and quality losses in sugar beet production in temperate regions in Central Europe. Under arid conditions, silicon (Si) application reduced beet yield losses under drought. Similar data for temperate climates are missing.
