Effect of foliar application of a fertilizer containing silicon and calcium on the yield and technological quality of sugar beet roots

Abstract

In the experiment carried out in Sahryń village (50°40′42″N, 23°47′35″E) in 2019–2020, the impact of threefold foliar application of Si and Ca-containing fertilizer, fourfold application of fungicides and the combination of both of these combinations on the yield and technological quality of sugar beet roots in conditions of strong infection pressure of Cercospora beticola Sacc. The effects were compared to the control. Triple foliar application of the fertilizer had a beneficial effect on the root, biological and pure yield of sugar. The biological and pure yield of sugar increased in the following sequence: control; 3x foliar application of the product with Si + Ca; 4x fungicide treatments; 3x foliar application of the product with Si + Ca + 4x fungicide treatments. A foliar application of silicon and calcium products can help implement a “field to fork” strategy.
