This study was carried out in order to determine the effects of dill, clove and hyssop essential oils and fungicides applied on sugar beet roots on beet storage quality during the storage period. The roots of Esperanza (KWS) variety, which was produced in the experimental areas in 2019, were used in the study. Roots were treated with 100, 500 and 1000 ppm doses of dill (Anethum graveolens L.), clove (Szygium aromaticum) and hyssop (Echinophora tenuifolia) essential oils, synthetic fungicide (80% Thiram) and Tween-80 right after harvest and the roots were placed in the storage. Weight loss of roots determined at 15-day intervals from the beginning of the storage period, dry matter ratio, brix, polar sugar, reducing sugar and alpha amino nitrogen contents, phytotoxicity and fungal infection development at the end of the 3-month storage period. The applications made in the research significantly affected the post-harvest weight and quality losses in beet. Depending on the applications, the weight losses at the end of the 3-month storage period varied between 9.43-19.90%, and the weight losses in essential oil applications were lower than the control. The highest dry matter content and brix values were obtained from clove essential oil and fungicide and Tween-80 applications. While Tween-80 and fungicide applications increased the polar sugar content compared to the control, 1000 ppm clove essential oil caused a significant decrease in the polar sugar content. In the study, reducing sugar and alpha amino nitrogen contents of roots applied 1000 ppm essential oil E. tenuifolia essential oil were lower. E. tenuifolia essential oil showed the highest antifungal activity against white mold and green mold infections. It was concluded that with the application of essential oil to the roots after the harvest, both weight and quality losses and the development of fungal diseases can be reduced, however, some active substances may cause phytotoxicity in the roots.

In this study, the effect of different phosphorus doses application on the yield and nutrient uptake of sugar beet plant was investigated under field condition. The study was carried out in Sivas province in 3 replications according to the randomized plot design and Valentina was used as the sugar beet variety. Phosphorus doses were; 0 kg P da-1, 15 kg P da-1, 30 kg P da-1 and applied as triple super phosphate (TSP). Leaf samples were taken approximately 80 days after the planting of sugar beet plant, nitrogen (N), phosphorus (P), potassium (K), calcium (Ca), magnesium (Mg), iron (Fe), zinc (Zn), manganese (Mn), copper (Cu) concentrations and yield were determined at harvest. Research results indicated that the yield increased depending on the increasing phosphorus doses and the highest yield was obtained at 30 kg P da-1 dose with 8151.0 kg da-1. In addition, the highest nitrogen, phosphorus and potassium concentrations were found at 30 kg P da-1 dose (4.77% N, 0.74% P and 2.39% K, respectively). However, the research found that calcium and magnesium concentrations decreased with increasing phosphorus doses. While only iron concentration among microelements increased with phosphorus applications, zinc, manganese and copper concentrations decreased due to increasing phosphorus doses.

Sugar beet is an important agricultural and industrial crop that contributes to Turkey’s economy. It is not only the source of sugar production in our country but also become an important sector with seed production. The seeds are one of the most important issues directly affecting the root yield and quality of sugar beet. There are a lot of registered sugar beet varieties and sufficient seed production in Turkey. According to the data in 2020 year, the seeds of sugar beet varieties were produced with a sowing area of 11.891 decare, seed production was 2.317 tons and 198 kg/da in seed yield. The seed amount is completely belonging to the seed companies operating in the private sector. Besides, 413 tons of sugar beet seeds were imported and 11.312 million dollars was paid, while 143 tons of seeds were exported and 1.584 million dollars income was obtained in 2020. The sugar beet plant produces leaves above the ground and root in the first year, and grows the stem, branch, flower and seeds in the second year. Therefore, seed production needs a long time and intensive labor requirement. In order to shorten this two-year period in seed production of sugar beet, firstly seedlings belonging to male and female lines of a hybrid variety are grown and then, the seed production is performed by transplanting these seedlings. In this review, commercial hybrid seed production of sugar beet is explanied in detail.

In this study, the effect of agribor fertilizer (18% pure B) on yield features of sugar beet were investigated. The study was conducted on ustifluvent subgroup soils according to soil taxonomy of agricultural faculty of Gaziosmanpaşa university. Randomized block experiment design with three replications were used and three treatments of agribor fertilizer 0.18 kg da-1 B (1 kg da -1 agribor); 0.27 kg da-1 B (1.5 kg da -1 agribor); 0.36 kg da-1 B (2 kg da -1 agribor) and control (no fertilizer) were applied. The effects of applied doses on yield properties were studied. From yield properties for sugar beet tuber weight, green leaf weight, and proportion of polar sugar in tuber were investigated. Results showed that green leaf and proportion of polar sugar in tuber not statistically important but the first application (0.18 kg da-1 agribor fertilizer) gave an statistically important yield increase in sugar beet. Boron contents of soils and boron uptake of plant species should be considered at boron application.

In this study, it is aimed to determine sugar beet production in Konya province, operation of factories in the region, the situation of farmers, privatization, production structure of sugar beet and the problems based on it. For this purpose, data were collected by questionnaires from 175 producers, who were selected according to Probability-Based Sampling method, from the producers operating in the cooperatives registered in the Association of Beet Cultivators Cooperatives (Pankobirlik) in Ilgın district of Konya. According to the findings, the difficulties encountered in production were listed as high irrigation cost of sugar beet (87.4%), difficulty in combating diseases and pests (77.7%), excess labor demand compared to other products (74.3%), and insufficiency of water in the region (72.0%) in sugar beet production. In addition, about 77% of producer’s state that product prices are low. Approximately 60% of the producers in the region have stated that they are against the privatization of sugar producing factories. When the results are evaluated, it is necessary to take into consideration the costs in determining sugar beet purchase prices and to include sugar beet production within the scope of support to reduce production costs. In addition, it is considered necessary to take essential steps by considering producer opinions on privatization and to review sugar policies.
