Efficiency and Management of Nitrogen Fertilization in Sugar Beet as Spring Crop: A Review

Abstract

Sugar beet fertilization is a very complex agrotechnical measure for farmers. The main reason is that technological quality is equally important as sugar beet yield, but the increment of the root yield does not follow the root quality. Technological quality implies the concentration of sucrose in the root and the possibility of its extraction in the production of white table sugar. The great variability of agroecological factors that directly affect root yield and quality are possible good agrotechnics, primarily by minimizing fertilization. It should be considered that for sugar beet, the status of a single plant available nutrient in the soil is more important than the total amounts of nutrients in the soil. Soil analysis will show us the amount of free nutrients, the degree of soil acidity and the status of individual elements in the soil so that farmers can make a compensation plan. An estimate of the mineralizing ability of the soil, the N min, is very important in determining the amount of mineral nitrogen that the plant can absorb for high root yield and good technological quality. The amount of N needed by the sugar beet crop to be grown is an important factor, and it will always will be in the focus for the producers, especially from the aspect of trying to reduce the N input in agricultural production to preserve soils and their biodiversity but also to establish high yields and quality.

UAV‐based NDVI estimation of sugarbeet yield and quality under varied nitrogen and water rates

“…As reported by Varga et al (2022), the application of N fertilizer can increase the sugarbeet root yield; they note, however, that a linear model had a negative trendline for the sugar concentration. This was not the case in our trial.…”

“…Sugar yield (ERS) is typically linearly related to biomass production and N uptake (Varga et al, 2022). However, Last et al (1983) has shown that N rates above 200 kg N ha −1 did not increase sugar yield; in fact, sugar yield was maximized with 125 kg N ha −1 rate.…”

“…However, Last et al (1983) has shown that N rates above 200 kg N ha −1 did not increase sugar yield; in fact, sugar yield was maximized with 125 kg N ha −1 rate. Furthermore, Varga et al (2022) reported that increasing N rate to 240 kg N ha −1 resulted in decreased sugar concentration to 15.7%, compared to 17.1% in the control treatment, although the ERS was virtually the same, averaging 5.7 t sucrose ha −1 . Although N fertilization tends to increase the root yield, the linear model has a negative trendline for the sucrose content.…”

Acclimation of sugar beet in morphological, physiological and BvAMT1.2 expression under low and high nitrogen supply

“…Sugar beet ( Beta vulgaris L.) is a biennial heterogeneous pollinated crop, which is important in sugar production and non- food energy supply [ 28 , 29 ]. Nitrogen is the most important nutrient limiting factor to sugar beet, which growth and taproot development directly related to N level in surrounding environment [ 30 ]. It was found that N deficiency led to low yields, but too much N reduced root quality in sugar beet [ 31 , 32 ].…”

UAV‐Based Prediction of Sugarbeet Yield and Quality

“…Based on research conducted by the Amalgamated Sugar Company and the University of Idaho, it is typically recommended that growers apply all N preplant to ensure N is available to the crop by the six‐leaf growth stage. On the other hand, literature review has shown that sugarbeet crop need for N is at peak during the time of most intensive leaf growth during June–July (Varga et al., 2022). Some researchers found that N deficiency in sugarbeets could be corrected by topdressing N in June (Gilbert et al., 1981) without yield losses.…”
