Effects of shading and of seasonal differences in weather on the growth, sugar content and sugar yield of sugar-beet crops

SummarySeven field experiments were made on the effect of two harvesting dates on the nitrogen requirements of sugar beet. All were on Rauceby series soils overlying oolitic limestone in Lincolnshire.Nitrogen fertilizer increased sugar yield in all experiments, and yield was considerably higher at the mid-December harvest than in early October. On average, the sugar-yield response to nitrogen was greater at the late harvest, and the requirement for nitrogen was about 45 kg/ha higher then than at the early harvest. Sugar content was depressed less at the late harvest than at the early by increasing nitrogen rate.These results suggest that farmers should apply more nitrogen to fields that they plan to harvest late than to early-harvested fields; they also have implications for the conduct and interpretation of nitrogen response experiments on sugar beet.

Seed Inoculation

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%.

Yield Responses

SUMMARYRoot and sugar yield responses of the Polyrave variety were more favourable to the lower of two population levels (70,000 and 92,000 beets/ha.) and to the wider of two between-row distances (60 and 50 cm.). When the triploid Trirave variety was space planted and, for comparison, conventionally planted and thinned to 3 population levels at 60 cm. between-row distance, the intermediate (87,000 beets/ha.) level gave the highest sugar yield. The thinned treatments consistently outyielded the corresponding space-planted treatments. Space planting at 40 cm. between-row distance resulted in high beet populations (130,000 beets/ha.) which evoked unfavourable responses in root and sugar yield and even in sugar content.

The paper highlights the assessment of Verhnyatska selection new combination valuable multigerm of lines – pollinators (МP) efficiency, МS of lines of a different origin and heterozis of hybrids created on their basis. Verhnyatska МP are productive, combination-valuable and plasticity, proved by the hybrid combinations with МS by materials of all skilled-selection stations of a network of Institute of biocrops and sugar beet. At the grade test of 2018 more successful were combinations with МS by lines Ivanivska and Bila Tserkva research selection station. Sugar yield in hybrids made 111.4–108.9 % on the average. A number of experimental hybrids line created with Verhnyatcka selection lines-pollinators in 2019 is listed among the best in sugar yield per hectare. The submitted hybrids STs191125 and STs191134 were characterized by a high parameter of productivity (117.6 and 113.8 % to the standard accordingly). A number of the best hybrids for study in variety ecological testing is selected. Heterosis effect was observed in some cross combinations. The best parameter on productivity (110.0 %) was in the hybrid STs191135 – МS originator of a line of Yaltushkivska RSS. Sugar yield and output were higher than the standard by 8.4 and 14.2 %. The satisfactory parameters of efficiency were observed in the STs190309 hybrid. Its productivity made 104.0 %, sugar yield – 104.1 %, sugar output – 111.8 % to the standard. Significantly high sugar output was in the hybrid STs190815 (119.6 %), where both components of crossing were of Verhnyatska selection. The parameters of productivity, sugar content and yield were 107.7, 100.9 and 109.2 %. Due to a genetic variety of initial materials and successful selection of parental components, their combinational ability and plasticity made it possible to receive new hybrids. Multigerm line-pollinators have high selection value of efficiency parameters. Key words: sugar beet, multigerm, pollinator, fertility, selection, hybrid, productivity.

A field experiment was performed to determine the effects of using humic acid with irrigation on quantitative and qualitative yield traits of sugar beet grown on calcareous soils in Esfaraen, located in the North-East of Iran. Treatments consisted of three levels of humic acid concentration (zero or control, 2.5 and 5 L ha-1) and the number of applications (once 45 days after planting; twice, 45 and 75 days after planting; three times, respectively 45, 75 and 105 days after planting). The effect of the two experimental factors on sugar beet yield traits such as the content of sucrose, refined sugar, molasses forming substances, root yield and refined sugar yield were evaluated. The results proved the existence of a significant interaction between humic acid concentration and the number of applications on all parameters under study. The application of humic acid caused a significant increase of sucrose, refined sugar, root yield and refined sugar yield and a reduction in molasses forming substances content, compared to the control. The increased amount of sucrose and refined sugar content in all applications in concentration of 2.5 L ha-1 humic acid was more than with 5 L ha-1. Similarly, the content of molasses forming substances showed more reduction in 2.5 L ha-1 than in 5 L ha-1 treatment. However, the results revealed that the highest root yield and refined sugar yield, as the main qualitative and quantitative parameters of sugar beet yield, were achieved by three times application of 5 L ha-1 that had 24 and 37% increase compared to control.

In 2013 and 2014, in Sahry (south-eastern Poland, 50°41’ N and 23°46’ E) 6 different variants of sugar beet foliar fertilization were investigated. Beet yield for variants with foliar fertilization was on average 14.2tha–1 (15.6%) higher than the control and the biological sugar yield was higher by 2.4tha–1 (14.2%). The technological sugar yield increased about 2.1tha–1 (13.9%) on average for variants with foliar fertilization in comparison with the control. Foliar fertilization had no significant effect on sugar content but the effect on melassigenic components content (-amino-nitrogen, K and Na) was ambiguous. The results obtained show that the cultivation of sugar beet as a following crop after winter rape is possible and can provide good results.

SummaryThe evaluation of sugar beet genotypes under different climate conditions is a principal goal of breeding programs. In most studies, environment has a high influence on the qualitative and quantitative traits of sugar beet. Therefore, data collected from different environments may contribute to more accurate genotype selection. In this study, the effect of different environments on sugar beet genotypes’ performance was evaluated using a meta-analysis method based on Hedges’ technique. Data were collected from 149 trials conducted in twelve regions in Iran over 15 years (2003–18). For all trials, the value of the traits was weighted, and subsequently the effect size, reaction ratio and confidence interval were estimated. Among the studied environments, Khoy had a positive effect on root yield, sugar content, sugar yield and white sugar yield. As could be expected, the effect of environment on final yield formation was high, so that the Shiraz environment had a negative effect on root yield and sugar yield. Overall, the ranking of environments based on the meta-analysis results was quite different from that obtained by comparison of mean results.

Industrial Storage

When storing sugar beets in natural conditions, transformations of the chemical composition occur in it, leading to the accumulation of non-sugars, which reduces the processing efficiency and sugar yield. The use of the technology of forced ventilation of the air environment of the kagats is aimed at reducing the negative impact of the ongoing processes. This study presents the results of changes in the technological properties of sugar beets during industrial storage of two types: in a ventilated rack, in a rack without ventilation. It was shown that forced ventilation of the air in the stagger led to slower development of diseases of root crops with stag rot, the processes proceeded 2 times slower. Changes in the chemical composition of sugar beets after 45 and 60 days of storage are shown. When sugar beets were stored in a ventilated stagger for 60 days, the daily decrease in sugar content was 1.6 times lower than when stored in a staggered rack without ventilation; the increase in the content of reducing substances is 3.5 times lower, α-amino nitrogen, potassium, sodium - on average 1.2 times lower. The calculated sugar yield for the storage conditions of sugar beets in a ventilated trough was 1.1 times higher than when stored in a trough without ventilation. It has been established that the creation of more favorable conditions for the air environment of the sugar beet pile through forced ventilation reduces the intensity of natural biochemical and microbiological processes in root crops, extends the shelf life of their technological properties, and ensures the economic efficiency of sugar production.

The impact of non-treated and primed seeds on molasses components, sugar content and technological white sugar yield of the same cultivar of sugar beet root was investigated. The study was conducted in 2012–2014 at the Experiment Field Station of Warsaw University of Life Sciences – SGGW in Skierniewice (51°97'N, 20°19'E) in the central region of Poland. The use of primed seeds resulted in a higher technological white sugar yield with higher sugar content and lower content of α-amino nitrogen in the roots. Also, seed priming increased the technological value of the roots by a lower share in the root yield fractions of the root weight less than 300 g, characterized by lower sugar content and a higher content of α-amino nitrogen.
