In 1982—1990, the Sugar Beet Research Centre conducted a total of 68 fertilizer placement trials. The present paper deals with 23 trials from five field experiment series. In the evaluation of the results, other experiments conducted at the Sugar Beet Research Centre have also been referred to. The field trials were conducted on experimental farms of the Sugar Beet Research Centre and of sugar factories. The soil type of the experimental fields varied from compact clay to finesand. The soil pH was high (6.7 —7.4) and the nutrient status good. The fertilizer used was an Na-containing compound fertilizer (N 13 %, P 6 %, K 9 %, Na 6 % in 1982—1987; N 15 %, P 6 %, K 8 %, Na 5 % as from 1988). The fertilizer was applied with a fertilizer drill. A disk bill was used in 1982—1983; thereafter a thin spring tine bill was used. Placement of fertilizer 3—6 cm to the side and 3 cm below the seed increased the root yield of sugar beet by 5—6 %, on an average, as compared to broadcasting. The yield increase ranged from 0 to 24 %. The yield increase from fertilizer placement correlated negatively with the sugar beet yield level. The nutritional status and humus content of soil, and soil type did not affect the yield increase from fertilizer placement. The seed bed preparation one-pass power harrow or conventional method had no significant effect on the yield increase from fertilizer placement. Increasing the level of fertilizer reduced the yield increase from fertilizer placement in some of the trials. This was not always the case, however. Placement usually gave a slightly higher sugar content than did broadcasting. Placement reduced the potassium content of the beet slightly and increased the extractability of sugar. As compared to broadcasting, placement increased the recoverable sugar yield relatively slightly more than the root yield. Placement of the fertilizer 3 cm to the side (3 or 6 cm below the seed) yielded a better result than placement 9 cm to the side of the seed. The depth of placement did not affect the yield. In most trials, placement of the fertilizer reduced the plant population only slightly as compared to broadcasting. The harmful effect in these trials was not significant even with the smallest distance from the seed, i.e. 3 cm. In practice, placement too close was shown to inhibit or to retard germination of the beet. It is therefore recommended that the fertilizer be placed 5—6 cm to the side and 3—4 cm below the seed.

Sugar beet yielding and, thus, the profitability of its cultivation depends on various conditions. These are mainly a&nbsp;dose of nitrogen fertilizing and anti-fungal plant protection. Based on the research carried out in a private-owned farm in Biała commune, Opole province, Poland, it was observed that the most important factors influencing plant development and root yield of sugar beets (var. Kassandra and Cortina) were genetic features of the investigated varieties and fungal control. They increased considerably root yield and sugar content. The doubled nitrogen dose from 90 to 180 kg N/ha enhanced a slight, statistically insignificant, root yield increase and a lower sugar content in beet roots. The three-year research showed that weather conditions during the vegetation period had a decisive effect on sugar beet plants development and fungal infestation. The variety Cortina was characterized with a significantly higher yield and a higher content of treacle forming compounds in the roots. The increase of N rate from 90 to 180 kg N/ha caused a significant increase of average root mass, leaves and dry matter yield and potassium and N-NH<sub>2</sub> in roots, but it also lowered sugar content. In the years with favorable conditions for fungal infestation, the use of fungicides helped to obtain a higher leaf/root ratio, higher root mass, higher root and leaf yield and higher dry matter and sugar yields. However, it did not have an effect on the content of chemical compounds producing treacle in sugar beet roots.

This study was conducted to evaluate the surface and subsurface drip irrigation (SDI) application effects on sugar beet crop performance, under two levels (100% and 80%) of water application depth. The experimental design was a split plot with four replications. Laterals were set every second crop row (1 m apart), with emitters spaced 1 m apart. In the case of SDI, laterals were buried 0.45 m under the ground. Soil moisture measurements were taken up to 75 cm depth, using the TDR method. The soil water content and the yield characteristics of each treatment were recorded. Irrigation method showed to affect crop performance significantly while water application level was less critical. The experimental results indicated that the subsurface drip irrigation leaded to a greater yield and higher sugar content making significant water saving compared to surface drip irrigation.

This paper analyzes the impact of genes and proportional contribution of parental genotypes on the inheritance of root yield and sugar content in diploid hybrids of sugar beet. The survey included two diploid male-sterile monogerm lines and three single (SC) male-sterile hybrids as maternal components, while three multigerm diploids were used as pollinators. The partitioning of genotypic variance into additive and dominant components was performed by half sibling (HS) and full sibling (FS) covariance. The proportional contribution of individual components of crossbreeding (lines, testers, and interactions) was exhibited in the expression of certain characteristics of F1generation. Genotypic variance components showed a significant effect of nonadditive gene action (dominance) in the inheritance of root yield and sugar content, while the additive effect of genes was less significant. Maternal components had a greater proportional contribution to root yield, while lines, pollinators, and their interactions had an equal contribution to sugar content.

Sugar Beet Root

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 = &ndash;0.485**, L-2: r = &ndash;0.096, L-3: r = &ndash;0.687**, L-4: r = &ndash;0.337**) whereas at all four localities it was in negative correlation with extractable sugar (L-1: r = &ndash;0.634**, L-2: r = &ndash;0.407**, L-3: r = &ndash;0.930**, L-4: r = &ndash;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**).

The research was conducted on 11 sugar beet varieties, grown at the Rumokai Experimental Station of the Lithuanian Research Center for Agriculture and Forestry, in 2016 and 2017. The experiments were carried out on two backgrounds: the crops were not sprayed and sprayed with fungicide epoxiconazole 125 g l–1. During the study years, rust (causative agent Uromyces beticola), powdery mildew (causative agent Erysiphe betae Vaňha Weltzien) and leaf spot disease (causative agent Cercospora beticola Sacc.) were the most prevalent in sugar beet. Rust, the intensity of which was 9.66–61.79%, caused most damage to sugar beet. The intensity of powdery mildew was 12.71–55.98% and that of leaf spot disease was 7.47–54.23%. Of the investigated varieties of sugar beet, the most sensitive to leaf spot disease were ‘Merens’, ‘Balear’, ‘Davinci’, ‘Kashmir’ and ‘Pottok’, the most resistant were ‘Berton’, ‘Selma KWS’ and ‘Wellington’. ‘Merens’ and ‘Texel’ were the most sensitive to rust. This disease was least damaging to the ‘Minta’, ‘Berton’ and ‘Strauss’ varieties. Powdery mildew was most harmful to leaves of the ‘Merens’, ‘Balear’ and ‘Minta’ varieties of sugar beet. The most resistant to powdery mildew was ‘Texel’. According to the average two-year data, the most productive was the ‘Pottok’ variety, whose root yield was 90.46– 93.85 t ha–1. The ‘Straus’ variety had the highest sugar content. Epoxiconazole increased the sugar beet yield from 0.44 to 6.53 t ha–1 in 2016 and from 0.07 to 11.63 t ha–1 in 2017.

In Germany, the guidelines for variety trials with sugar beet require plots with 80–100 beets for a representative estimation of root yield. If possible, one or two head rows shall be planted perpendicular to the plots to avoid border effects at open alleys. The optimum sample size was determined in the 1970s and the effect of head rows has not yet been systematically studied. The aim of the present study was to quantify the effects of sample size and head rows on the precision of yield and quality data of sugar beet. Two series of field trials were carried out in Germany in 2016–2017. In the series “sample size”, conducted at 9 environments, samples of 30, 60, 90 and 120 beets were compared. With increasing number of beets, coefficients of variation and least significant differences for yield and quality parameters decreased, especially when the sample size was increased from 30 to 60 beets. Compared to the current standard of 90 beets, the precision of samples with 60 beets was similar for sugar content but lower for root yield. It is concluded that the current sample size should not be reduced. In the series “head rows”, ten variety trials were conducted without and with head rows. The precision of trials with and without head rows did not differ in general. The effect of head rows on least significant differences for root yield and sugar content was not consistent among environments. With head rows, absolute root yield (tonnes per ha) was lower and sugar content was higher than without, but the rank of varieties in relative white sugar yield remained unchanged. Sugar beet varieties can thus be tested in trials with and without head rows without losing precision, even within the same trial series.

Small-plot trials conducted in 2013–2015 studied the impact of longer vegetation periods (by means of earlier drilling and/or later harvest) on production results of two sugar beet cultivars – one nematode-tolerant cultivar and one cultivar without such tolerance. The trials took place at two sites with different Heterodera schachtii infestation levels. In all trial seasons, root yield was significantly higher in the earlier drilled plots. On average, prolongation of the vegetation period in spring by 13 days increased root yield by 10.9%. Therefore, each day by which drilling is postponed represents a 0.7–0.8% loss of yield. As to sugar content, no statistically significant benefit of vegetation period prolongation by early drilling was found. The spring gain was slightly higher for the non-tolerant cultivar than for the tolerant one on average over all trial seasons. This result confirms the theory that nematodes impact the crop mainly in later stages of vegetation, and early drilling can thus help eliminating, to a certain degree, the risk of nematode damage. In the autumn, root yield increased by 14.3% on average over 39 days. The autumn daily gain was about half of the rate found in the spring. The increase in sugar content was between 0.6% and 1% (abs.) on average. Autumn growth achieved at the non-infested site was much higher than at the infested site.

Seed Inoculation

Effect of sugar beet seed inoculation with a bacterium Pseudomonas fluorescens and treatment by fungicides Thiram&nbsp;42-S and Dithane S-60 with and without seed inoculation aiming to control Aphanomyces cochlioides &ndash; 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 &lt; 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.&nbsp;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%.

Sugar beet and sugarcane are two major crops for sugar extraction throughout the world. However, the sugar beet importance is not just about sugar production but it also plays an important role in crop rotation and increased productivity in various industries as well as livestock feed. In this study the long-term (2009-16) field trial effect of alfalfa (4 years)-winter wheat (1 year)–fallow (1year)-sugar beet rotation on yield and quality parameters of sugar beet were evaluated for two consecutive rotations. The field trials were carried out at single location in Karaj, Iran, using randomized complete block design with four replications. Analysis of variance showed that the seasonal factors influenced different traits. In the first and second rotations, the root yield ranged from about 56.5 to 83.2 and 61.4 to 77.8 t ha-1, respectively with significant difference among cultivars in the first rotation. However, no significant difference was observed among both rotations in terms of root yield. Same results were obtained for sugar yield in both rotations which illustrates the stability of the above-mentioned traits. Except for sugar content, significant difference was observed among other traits in both rotations. We show for the first time the effect of completing two rotation sequences on sugar beet performance and quality for decision making into a continual expansion/development of crop cultivation.

Background. While working with such cross-pollinated crops as sugar beet, the greatest problem is the fixation of valuable genotypes. Using apomixis to produce breeding material helps to accelerate the breeding process and save the desired combination of genes.Materials and methods. The research objects were 110 accessions of sugar beet from the VIR collection. Field experiments and assessments of the resistance to Cercospora leaf spot, monogermity, and non-bolting were performed according to VIR’s guidelines in 2016–2018 at Pushkin and Pavlovsk Laboratories of VIR and Maikop Experiment Station of VIR. The sugar level in roots was measured using an optical refractometer.Results. A comprehensive study of sugar beet accessions resulted in the development of apomictic lines with cytoplasmic male sterility, followed by an evaluation of their economically important characters. An extremely rare occurrence of biotypes with the 0-type sterility (less than 0.5%) was observed in the population. The seeds obtained from apomixis-prone lines demonstrated a significant difference during inbreeding from the seeds of fertile inbred genotypes: no inbreeding depression was observed in apomictic lines. Lines combining sterility and monogermity in their genotype were produced. Testing parent accessions and apomictic forms did not reveal significant differences in the sugar content and root yield, so the resulting forms can be efficiently used in future breeding programs.Conclusion. Using apomixis to develop sugar beet lines helped to fixate the sugar content level, biennial plant development cycle, and Cercospora leaf spot resistance. Thus, apomixis is promising for ensuring maternal inheritance and preserving the desired combination of genes in sugar beet, thereby accelerating the breeding process.
