Effect of the Application Date of Fertilizer Containing Silicon and Potassium on the Yield and Technological Quality of Sugar Beet Roots

Abstract

Water shortage and drought are a growing problem in Europe. Therefore, effective methods for limiting its effects are necessary. At the same time, the "field to fork" strategy adopted by the European Commission aims to achieve a significant reduction in the use of plant protection products and fertilizers in the European Union. In an experiment conducted in 2018–2020, the effect of the method of foliar fertilization containing silicon and potassium on the yield and technological quality of sugar beet roots was assessed. The fertilizer was used in seven combinations, differing in the number and time of application. The best results were obtained by treating plants during drought stress. The better soil moisture for the plants, the smaller the pure sugar yield increase was observed. It is difficult to clearly state which combination of silicon and potassium foliar application is optimal, as their effects do not differ greatly.

The Effect of Acaricide Control of the Two-Spotted Spider Mite Tetranychus urticae Koch on the Cultivation of Sugar Beet (Beta vulgaris L.) and on the Size and Quality of the Yield

“…Smaller increases were observed in 2019, when the value of the soil moisture was high and there was no drought stress. This confirms the results of previous studies, which prove the effect of field experiments of other authors [44]. Pure sugar yield is determined by the biological yield of sugar, which depends on the yield of roots, sugar content and the content of molasses-forming components.…”

“…Pure sugar yield is determined by the biological yield of sugar, which depends on the yield of roots, sugar content and the content of molasses-forming components. Root yield has the greatest influence on pure sugar yield [44,45].…”

Effectiveness of Bamboo Leaf Silica Applied with Nanosprayer and Growing Media on Yield of Red Beetroot (Beta vurgaris L.)

“…The diameter and length of beetroots correlate with the wet weight of beetroots. Beetroots weight can be increased by spraying 75 -150 g of silica per ha (Artyszak et al, 2021). Growing media containing goat manure increased root diameter by 27.14% and root length by 25.29%, while planting media containing goat manure and husk charcoal increased root diameter by 32.37% and root length by 31.34 % compared to control only Vertisol soil.…”

“…The dose of bamboo leaf silica fertilizer at 0.60 ppm still needs to be increased in order to increase the wet weight of red beetroots. Artyszak et al, (2021) reported that spraying 75-150 g of silica per ha was able to increase the wet weight of red beetroots.…”

“…The sugar content in beet tubers can be influenced by plants experiencing stress due to weather during the growing season. Silica spraying increases the sugar content of beet tubers when they are under stress due to drought stress (Artyszak et al, 2021).…”
