The article justified the necessity of developing a strategy for the improvement of the sugar beet subcomplex of the region on the base of the determination of the close relationship between beet-growing farms, enterprises engaged in the delivery, processing and sale of manufactured products. According to the authors, the optimization of the raw material zone should include the principle of maximum loading of sugar mills, taking into account the raw materials produced in the region, optimizing transport costs for its delivery. The analysis of the sown area, productivity and gross yield of sugar beets gives us the idea that the region takes the tenth place among the largest producers of sugar beets. The yield and gross yield in 2019 in agricultural enterprises amounted to 459.6 centner / ha, 2231.9 thousand centner (an increase of 13.6% and 9.4% compared to the level of 2018).For P(F)E, the average increase is 40%, which corresponds to 481 centner / ha, 18.3 thousand tons. The average sugar content of beets during acceptance and processing ranges from 17.96 to 18.3%, the sugar yield is 15.63%, the sugar content in molasses is 1.68%, and the average daily productivity is 16.11 thousand ton / day, loss in production is 1.27%. The authors found that the production efficiency of the sugar beet industry is directly connected with the growth of labor productivity, the introduction of modern technologies, cost reduction, and thus, each farm has the opportunity to get additional profit. One of the main problems in the agricultural sector of the economy is the use of available resources to obtain the largest number of products. In our opinion, the production efficiency of sugar mills is closely interconnected with the constructed logistics routes for the transportation of raw materials with the exception of repeated shipments, the proportion of sugar beets in the sown area, and the reliability of suppliers. In our opinion, the efficiency of sugar mills production is in close connection with the built of the logistic routes for transportation of raw materials with the exception of repeated transportation, the specific weight of sugar beet in the structure of the sown area and the reliability ensuring of suppliers. The problem of the effective development of the sugar industry is relevant and priority in solving regional policies, the implementation of which will not only eliminate the emerging imbalances and reduce imports, but also support the domestic producer.

Sugar Beet Root

This study analyzes the dynamics of sugar beet root, crown, and leaves fresh and dry matter (FM and DM, respectively) accumulation per plant and their mass ratio at different plant densities and nitrogen fertilization. The biennial field trials were set as four different planting densities (60,000, 80,000, 100,000 and 140,000 plants ha-1) and three methods of nitrogen application in spring: control – without nitrogen fertilization (N0), presowing only (N1), and presowing with topdressing (N2). Close to the maturation, the mean DM of the whole root, crown, and leaves on September 20, 2014 amounted to 28.8, 7.3 and 4.0 t ha-1, respectively, whereas it amounted to 20.7, 4.1 and 2.3 t ha-1 in 2015, respectively. Moreover, with regard to the plant densities, the highest root DM was at 140,000 and 100,000 (31.6 t ha-1 in 2014 and 22.4 t ha-1 in 2015), compared to the wider plant densities of 80,000 and 60,000 plants ha-1 (22.4 t ha-1 in 2014 and 18.1 t ha-1 in 2015). Nitrogen fertilization positively influenced on dry matter accumulation, but it was different within the years. On September 20, 2014, a presowing fertilization (N1) increased the root DM by 17%, compared to the control, whereas in 2015 the presowing with topdressing (N2) increased the root DM by 30%. The root-to-leaves FM ratio amounted to 1:3.9 on May 30, 2014, whereas it amounted to 1:0.1 on September 20, 2014. The leaves FM was at its largest on June 20, 2015, when the root-to-leaves ratio amounted to 1:1.1, and gradually decreased to 1:0.1 on September 20, 2015.

Main Effects

SummaryThree experiments (1970–2) on calcareous sandy loan tested all combinations of four plant densities (18500–124000 plants/ha), two amounts of potassium (0, 156 kg/K/ha) and sodium (0, 247 kg/Na/ha) fertilizer and two watering treatments on yield and chemical composition of sugar beet. The main effects of the treatments in all three experiments confirmed that at least 75000 plants/ha were needed for maximum sugar yield, that sodium fertilizer increased sugar yield more than potassium (+0.76 and +0.29 t/ha respectively) and that the crop responded to irrigation in some years (+1.35 t sugar/ha in 1970 and +1.67 t/ha in 1972).Analysis of the growth of the crop showed that increasing the plant density increased leaf growth per unit area from singling onwards and giving irrigation increased it from July; the effects persisted until harvest and were reflected in increased sugar yields. Fertilizer increased leaf growth early in the season but the effect disappeared later, although sugar yield was still increased. Interactions between plant density, fertilizer treatment and irrigation were small every year but there were some consistent effects on sugar yield. The results suggest that in commercial practice the optimum density is 75000 plants/ha; where irrigation is not practised, 247 kg/ha of sodium and 70 kg/ha of potassium fertilizer should be given. Where irrigation is applied, only 247 kg/ha of sodium needs to be given as the extra water increases the uptake of soil potassium.

This experiment was conducted in Homs Agricultural Research Station, Homs, Syria during 2007/2008 and 2008/2009 seasons to study the effect of sowing date and plant density on bolting for four sugar beet varieties, tow are monogerm varieties i.e. Parade and Etna, while the other are multigerm varieties i.e. Nadir and Mammoth. Three sowing dates were applied, began from 15/9 to 15/10, the interval between the sowing dates was 15 days. Three plant densities were executed (133 000, 100 000 and 80 000 plantha-1). Split plot design was used with three replicates. The combined analysis exhibited the significant effect of varieties (V), sowing dates (S), and plant densities (D) on all types of bolting (Early, medium, late and total). Least significant test (L.S.D 0.05) clarified that early autumn sowing (15/9 and 1/10) increased total bolting percent 74.86 and 44.88 % respectively, as compared with date (15/10) 15.57% (control). The plant density (133 000 plant ha-1) decreased total bolting percent 43.56% as compared with the other plant densities (80 000 and 100 000 plant ha-1) 46.35 and 45.40% respectively. The results showed that the monogerm varieties were superior and more resistant to bolting as compared with the multigerm ones.

A full liberalisation of the sugar market is hardly acceptable for Slovakia, because it would significantly affect not only the economic performance and employment across different sectors, but also their production structures, particularly in the farming-intensive regions. We nonetheless believe that the reform is necessary as the sugar sector remains the last unreformed CAP sector in the EU, which puts it in a better position vis-ŕ-vis other producers and farms. On the other hand, the justified claims of producers for the compensation of losses, similarly as the claims laid during the 1992 CAP reform, would disrupt the EAGGF budgetary framework through 2013, because only the claims of Slovak sugar beet producers would amount to some € 200 million during 2010–2015. We believe that the solution and consensus lies in the combination of reforms based on the scenarios of fixed quotas and falling prices, and/or the application of the “Midway situation” after 2011. The alternative setting of quotas, based the administratively assessed production efficiency levels for the individual EU countries, would also be unacceptable for Slovakia. In the recent past, the volume of investments in the Slovak sugar industry has been considerable and the most viable sugar refineries have already emerged from the selection process. The situation in the sugar beet sector is similar and the results of the “Fall in Prices” scenario until 2011 are largely similar to the situation before the accession to the EU.
