“…As well as, it is surrounded by many other farms, which makes it vulnerable to fungous pathogens that affect the leaves. These observations were confirmed by the owners' researchers of the farm themselves and the neighboring farmers as well as pervious research, which carried out in this zone farm (Ghazy et al, 2020).…”

Sugar beet (Beta vulgaris subsp. vulgaris) is root crop grown commercially for produce over 100 million tons per year of sugar (mainly sucrose) for worldwide consumption. Cercospora leaf spot is a foliar disease that caused by the fungus Cercospora beticola Sacc. can destroys the sugar beet yield. To identifying sugar beet cultivars with remarkable yield and disease resistance; six cultivars of sugar beet, namely Gergoria-KWS, BTS 2860, LP17B4011, MK 4199 (Emperator), Pintea, and Zeppelin were obtained. These six sugar beet cultivars were grown in experimental farm, Sakha Agriculture Research Station, Agriculture Research Center and examined under field growth conditions for two successive seasons, 2019/2020 and 2020/202. Disease severity percentage, root and foliage-associated traits, % of sugar and total soluble solids (% TSS) content were measured. Novel start codon targeted (SCoT) markers via PCR-based applications using ten SCoTspecific primers was used and genetic similarity among cultivars were estimated. The results divided the studied cultivars to three classes; the first contains; Gerogoria-KWS and BTS2860 cultivars appear to have the lowest % disease severity (1.00-2.67 % and 0.83-5 %, respectively) and they have longer roots, higher biomass for foliage and root (on fresh and dry weight basis), higher content of TSS % and sucrose in the both seasons. The second class contains; Pintea, MK 4199 (Emperator), and LP17B4011 cultivars exhibited the highest % of disease severity, the lowest biomass and shortest roots. The third class include, Zepplen cultivar had moderate of % disease severity and low TSS % content. In addition, the results of SCoT markers were showed that the average of

Leaf spot disease caused by Cercospora beticola Sacc. is the most damaging foliar disease threatening sugar beet production worldwide. The wide spread of disease incurs a reduction of yield and economic losses. The in-depth knowledge of disease epidemiology and virulence factor of pathogen is crucial and basic for preventing fungal disease. The integrated control strategies are needed for an efficient and sustainable disease management. The rotation of fungicides and crop could reduce the initial inoculum and delay the emergence of resistant pathogens. Spraying fungicides under the guide of forecasting models and molecular detecting techniques may hinder the onset of disease prevalence. The resistant varieties of sugar beet to cercospora leaf spot could be obtained by combining classical and molecular breeding methods. More effective approaches are supposed to develop for prevention and control for fungal disease of sugar beet.

“…Among others, cercospora leaf spot, a common leaf disease in plantations grown in the organic system, is responsible for a significant reduction in sucrose content in the roots [15]. In this system, the use of most chemical plant protection products is prohibited, but treatments with preparations containing copper and sulfur, which have good efficacy, are allowed [16]. In the case of high pressure of cercospora leaf spot, it is advisable to use varieties with increased resistance [17].…”

In the period of 2016–2018, two series of field studies on organic sugar beet growing (Beta vulgaris L.) were carried out in northern Poland on Luvisol loamy soil (medium–heavy) soil in Bałcyny and Płonne. The aim of this study was to decrease the yield gap between organic and conventional beets. Factors to increase the yield of organic beet were differentiated fertilization (cattle farmyard manure (FYM), compost, and Bioilsa) and choice of varieties (Eliska, Jampol, and Sobieski). The reference point was the conventional cultivation of the same sugar beet varieties, fertilized with manure and NPK mineral fertilizers, the prevailing standard of sugar beet cultivation in Poland. High sugar beet root yields exceeding the average yield in Poland by 25–30% were obtained in both studies, both in conventional and organic cultivation. Higher root and white sugar yields were obtained in the study conducted at Płonne (with similar soil conditions to those at Bałcyny), but they were characterized by higher temperatures during the growing season. The lowest root yields in both experiments were obtained by fertilizing the organic beet with compost (66.1 t per ha in Bałcyny and 78.13 t per ha in Płonne), which were 10.8% and 8.5% lower than the conventional crop, respectively. Higher root yields in organic cultivation were obtained by fertilizing the sugar beet with FYM, which reduced the differences from conventional beet to 7.7% in the study in Bałcyny and 2.1% in the study in Płonne. Thus, the results showed no need to convert cattle FYM to compost. The highest root yields in organic cultivation were obtained by fertilizing the sugar beet with Bioilsa N 12.5 supplemented with mineral fertilization of K, Mg, and S (Patentkali). This fertilization provided a yield of 78.1 t of roots per ha in Bałcyny, which is a reduction in the yield gap to 1.4%, a statistically insignificant value. Moreover, in the study at Płonne, organic sugar beet fertilized with Bioilsa and Patentkali yielded 86.7 t of roots per ha, compared to 85.6 t per ha of conventional beet, so a yield gap was not seen here. The choice of varieties was also of great importance for root and pure sugar yields in both farming systems. The lowest yields were obtained from the Eliska variety, and at Bałcyny, a change of beet cultivar to Jampol increased the organic root yield from 68.8 t per ha to 76.0 t per ha, while reducing the yield gap from 10.1% to 2.2%. At Płonne, replacing the Eliska variety with Jampol reduced the yield gap between organic and conventional roots from 6.6% to 0.3%.
