The results assessed from sugar beet microtrials at Kljajicevo (Serbia) in 2010 harvested at three harvest periods demonstrated that the average root yield tended to increase from the first to the third harvest period. The average increase in root yield between the first and the second harvest period was 29.06 t ha-1 or 32.76%, between the second and the third period 14.77 t ha-1 or 12.54% and between the first and the third period 43.83 t ha-1 or 49.40%. In average, the content of sugar in root showed a similar tendency. The highest increase in this parameter was registered between the second and the third harvest period and it amounted to 1.00% abs. Other indicators of sugar beet processing quality showed a slow increase or slight decrease depending on the harvest date, probably due to plentiful rainfall in September. Mean granulated sugar yield had an increasing tendency: 3.413 t ha-1 or 32.82% between the first and the second harvest period, 2.820 t ha-1 or 20.42% between the second and the third and 6.233 t ha-1 or 59.94% between the first and the third period.

The Green Deal adopted by the European Commission assumes a significant reduction in the use of pesticides and synthetic fertilizers. It is necessary to search for environmentally safe technologies that will prevent a reduction in crop yield. One of such methods, which was examined in the study, is the foliar application of silicon, which can have a positive effect on root yield and its quality. In the period 2017–2019, a field experiment was carried out in which the effectiveness of the application of various forms of silicon (orthosilicic acid, a mixture of orthosilicic and polysilicic acid and calcium silicate) in sugar beet cultivation was assessed. The applied treatments of foliar application increased the root yield by 10.7–11.7%, the biological sugar yield by 8.4–12% and the pure sugar yield by 7.2–11.8% as compared to the control treatment. The differences between the individual treatments in terms of these characteristics were insignificant. Their impacts on the technological quality of roots (content of sugar, α-amino nitrogen, potassium and sodium) were different.

Field trials for two seasons (2018/2019 and 2019/2020) were conducted to investigate the influence of the addition of three levels of potassium (K) (K1 = 60, K2 = 120, and K3 = 180 kg K2O ha−1) and/or sulfur (S) (S1 = 175, S2 = 350, and S3 = 525 kg CaSO4 ha−1) to the soil, as well as the sowing date (the 1st of September, D1; or the 1st of October, D2) on the potential improvement of physiology, growth, and yield, as well as the quality characteristics of sugar beet yield under soil salinity conditions. With three replicates specified for each treatment, each trial was planned according to a split-split plot in a randomized complete block design. The results revealed that early sowing (D1) led to significant improvements in all traits of plant physiology and growth, in addition to root, top, and biological yields and their quality, gross and pure sugar, and K- and S-use efficiencies based on root yield (R-KUE and R-SUE). The K3 level (180 kg K2O ha−1) positively affected the traits of plant physiology, growth, yield and quality, and R-SUE, and reduced the attributes of impurities, impurity index, and R-KUE. Additionally, the S3 level (525 kg CaSO4 ha−1) affirmatively affected plant physiology, growth, yield and quality traits, and R-KUE, and decreased impurity traits, impurity index, and R-SUE. The interaction of D1 × K3 × S3 maximized the yield of roots (104–105 ton ha−1) and pure sugar (21–22 ton ha−1). Path coefficient analysis showed that root yield and pure sugar content had positive direct effects with 0.62 and 0.65, and 0.38 and 0.38 in both studied seasons, respectively, on pure sugar yield. Significant (p ≤ 0.01) positive correlations were found between pure sugar yield and root yield (r = 0.966 ** and 0.958 **). The study results recommend the use of the integrative D1 × K3 × S3 treatment for sugar beet to obtain maximum yields and qualities under salt stress (e.g., 8.96 dS m−1) in dry environments.

Researches, which have lasted for two years, were carried out on long-term trial field at Rimski Sancevi, Novi Sad, Serbia. In this trial, the eight fertilization variants of N, P2O5 and K2O increased amounts were studied. Sugar beet root and tops yields were determined, as well as the elements of technological sugar beet root quality. Based on these results, percentage of sugar utilization and refined sugar yield was defined. In the spring, before applying of N fertilizer, amount of nitrate nitrogen in the soil and its influence on yield and quality was determined. The highest root yield in 2002 was produced at the variant N100 P150 K150, and in 2003 at the variant N150 P150 K150. However, in both years, referring to the variant N100 P100 K100, the differences were not statistically significant. Increasing of nitrogen amounts had negative effects on refined sugar yield. Amounts of NO3-N in the soil in spring, before sugar beet sowing, in 2002 had significant influence on root yield and refined sugar yield. In the year 2003, which was highly dry, high correlation ratio were gained between amounts of NO3-N in the soil and root quality parameters, but it wasn't significant between nitrogen amounts and root and refined sugar yield.

In 2005–2008, in several locations of southern Poland, the yield and technological root quality of two sugar beet cultivars (Esperanza and Henrike) cultivated in mustard mulch, straw mulch and in conventional tillage (with pre-winter plough) were investigated. Mustard mulch let to achieve the highest plant density during harvest. Replacing conventional ploughing with mustard mulch caused 9.4% root yield increase and with straw mulch 11.2%. Cultivation system had no effect on the content of sucrose and melassigenic components in the roots, except for potassium. Technological sugar yields obtained from mustard mulch were by 8.0% and in straw mulch by 11.3% higher than in the conventional tillage. Cv. Esperanza allowed getting the higher root yield, average fresh mass of single root and technological sugar yield, than cv. Henrike. In addition, lower content of alpha-amino-nitrogen was obtained from roots of the cv. Esperenza. In contrast, higher sucrose content and lower sodium content were found in the roots of cv. Henrike. The lowest variability in the sugar beet root yield features and technological quality was achieved from straw mulch.

Aiming at determination differences in leaf and root potassium concentration of diverse sugar beet genotypes as well as its effect on sugar beet root quality and yield. Investigations comprising 15 sugar beet genotypes (five multigerm lines, five hybrids and five monogerm lines) were carried out on two soil types (Calcic luvisol: L-1 and L-3 and Calcic gleysol: L-2 and L-4) during two growing seasons. Root yield of the investigated genotypes on Calcic luvisol (50 t/ha) was higher, than on Calcic gleysol (34 t/ha). In general, multigerm lines were known for the highest leaf potassium concentration (2.75%), lowest root one (3.78 mmol/100 g root), highest sugar content (13.8%) and best root extractable sugar (1.5%). Monogerm lines had the lowest leaf potassium concentration (2.51%), highest root one (4.24 mmol/100 g root), lowest sugar content (12.9%), and the poorest extractable sugar (10.7%). Root yield of the investigated hybrids (48 t/ha) was higher by 16% compared to multigerm lines yield (42 t/ha) and as much as 35% higher compared to monogerm lines (36 t/ha). Sugar beet root potassium was in significantly negative correlation with sugar content at three localities (L-1: r = –0.485**, L-2: r = –0.096, L-3: r = –0.687**, L-4: r = –0.337**) whereas at all four localities it was in negative correlation with extractable sugar (L-1: r = –0.634**, L-2: r = –0.407**, L-3: r = –0.930**, L-4: r = –0.749**). Potassium concentration in sugar beet leaf was in significant positive correlation with sugar content at three localities (L-1: r = 0.382**, L-2: r = 0.231, L-3: r = 0.717**, L-4: r = 0.516**).

Sweetpotato (Ipomoea batatas) cultivars, Carver, Potojam, Jewel and Centennial were evaluated for slip production, using topsoil, sawdust, sand and a general-purpose peat-based commercial growing media as bed covers. Temperature measured 2 inches (5.1 cm) below the surface of the hot bed varied with covers and date measured. Sand maintained the highest bed temperature, 77 °F (25.0 °C) at 0800 hr and 79 °F (26.1 °C) at 1400 hr, throughout the growing season. Peat-covered roots produced the maximum number of slips/plot (111), while roots covered with topsoil and sawdust produced comparable yields, 55 and 45 slips/plot, respectively. Slip production varied according to harvest date, with the third harvest producing the most slips/plot (83 and 153, in year 1 and year 2, respectively), which, was likely related to increased temperatures. Cultivar significantly influenced number of slips, length of slips, and number of roots per slip. `Potojam' was the most prolific slip producer for both early and mid season production under all bed covers.

Effect of sugar beet seed inoculation with a bacterium Pseudomonas fluorescens and treatment by fungicides Thiram 42-S and Dithane S-60 with and without seed inoculation aiming to control Aphanomyces cochlioides – root decay agent was studied. The trial lasted for three years on two soil types (Mollic Gleysols and Eutric Cambisols). The following parameters of sugar beet yield and quality were investigated: root yield, sugar content, sugar in molasses, sugar yield as well as percentage of the infected and decayed plants as a consequence of parasite fungus infestation. The highest average sugar beet root yield was obtained in the variant of the seed treated with fungicide Thiram 42-S and inoculated with bacterium P. fluorescens (85.15 t/ha). However, there were no statistically significant differences (P < 0.05) between the above-mentioned variant and the one with seed inoculated only with bacterium P. fluorescens (84.63 t/ha). The highest mean sugar content of 16.39% was also accomplished during the three-year investigation in the variant of the inoculated seed treated by fungicide Thiram 42-S. All other variants accomplished statistically very significantly lower values of this parameter. The same variant was characterized by the highest mean sugar yield value (12.79 t/ha) on both soil types. Namely, an average sugar yield of the variants inoculated with bacteria was 11.22 t/ha and by 44.22% higher compared to an average yield of non-inoculated variants. The highest percent of the infected and decayed plants (average value on both soil types in the three year investigation) was reported in the control variant (28.92% infected and 25.00% decayed plants) whereas the lowest one was detected in the variant of the seed inoculated with bacterium P. fluorescens in combination with low dose of fungicide Thiram 42-S (4.70% infected plants and 2.88% decayed plants). An average percent of the infected plants inoculated with bacterium P. fluorescens was 9.13% whereas the aforesaid value of the plants infected with parasitic fungus A. cochlioides in non-inoculated variants was by 146.00% higher being 22.42%.

The strategy “from farm to fork” assumes a reduction in the usage of fertilizers and plant protection products in EU agriculture. The aim of this study, conducted over the years 2017–2019 in several locations in Poland, is to evaluate the application of growth activators with and without plant growth-promoting rhizobacteria to reduce mineral nitrogen fertilization without negative effects on the root yield. We studied the effect of these activators on selected soil properties. The experimental treatments included the application of the growth activators Penergetic (K + P) and Azoter, which contains the bacteria Azotobacter chroococcum, Azospirillum brasilense, and Bacillus megaterium, before sowing or during vegetation. The nitrogen rates were reduced by 30% in comparison to full nitrogen mineral fertilization (control treatment). In selected experiments, the application of Penergetic and Penergetic with Azoter caused a higher content of nitrate nitrogen (N-NO3) and ammonium nitrogen (N-NH4) after the sugar beet harvest as well as higher contents of mineral nitrogen (Nmin), P, K, and Mg in the soil in comparison to the treatment with the full dose of mineral nitrogen fertilization. The obtained results proved that it was possible to reduce the mineral application of nitrogen by 30% without a decrease in the biological and pure sugar yield, and even with an increase in the sugar yield caused by the application of the growth activators Penergetic (K + P) and Azoter.
