Gul, Volkan; Gidik, Betul; Sefaoglu, Firat
Sunflower, an oil plant grown in many parts of the world, is capable of growing in many different climatic conditions. It is of great importance to carry out studies on the adaptation of new varieties and to determine the varieties suitable to the ecology of the region in areas where sunflower cultivation is intense. This study was carried out to determine yield and quality characteristics of some sunflower cultivars (SANBROMR, BOSFORA, SYBARBATI, ROSETTA, LG5485, P64LL62, SYGIBRALTAR, P64LC108 P64LE119, P64LP130, P63LE113, 11TR077, ESNIEGARA, ADELYA, and DERAY) under Bayburt providence conditions of Turkey in 2020-2021. It has been determined that there are significant differences between the cultivars for the traits examined. The highest average seed yield (4194.2 kg ha-1) and average linoleic acid content (65.09%) were found for BOSFORA. The highest average oil content ESNIEGARA (48.78%) and average oil yield respectively were obtained from ESNIEGARA (186.02 kg ha-1) and BOSFORA (182.93 kg ha-1) varieties and the highest average oleic acid content was obtained from 11TR077 variety (41.78%). The results of this study emphasized the importance of varieties in sunflower growing. BOSFORA and ESNIEGARA varieties had high yield and quality characteristics in the ecologies of a semi-arid climate.

Vermicompost, which is not harmfull to the environment, and is increasing in agricultural production in terms of both gaining to the soil and benefiting the waste. This research was carried out in 2019 in Bayburt ecological conditions in order to determine the impacts of different doses of solid (250, 500 and 750 kg da(-1)) and liquid (0, 250, 500 and 750 ml da(-1)) vermicompost fertilizers on the flowering and maturation period (days), stem diameter (cm), table diameter (cm), plant height (cm), thousand weight (g) seed yield (kg da(-1)), seed internal rate (%) oil ratio (%) and oil yield (kg da(-1)) of sunflower (Helianthus annuus). In the experiment, it was determined that all parameters were statistically significant compared to p<0.01. The highest seed (218.7 kg da(-1)) and oil yield (75.9 kg da(-1)), which are the most important parameters in oil sunflower, were obtained in 750 kg da(-1) solid and 750 ml da(-1) Liquid vermicompost application (K3S3). As a result, the use of solid and liquid vermicompost application in oil sunflower together will be beneficial in obtaining the highest healthy, high quality seed and oil yield.

Gul, Volkan; Gidik, Betul; Girgel, Umit
This study was carried out in 2018 on an experimental field of Bayburt University in order to demonstrate the effect of different doses of vermicompost on the yield and oil quality in oilseed sunflower varieties. The experiments were carried out in randomized full-block design with three replicates. In the experiments, it was found that administering 100 kg da(-1) of vermicompost to the sunflowers yielded the best results in terms of grain yield (130.81 kg da(-1)), fat ratio (48.21%). and fatty acids parameters (saturated fatty acid ratio 15.30%. unsaturated fatty acid ratio 84.71%). In conclusion, we are of the opinion that, although there is an insufficient number of studies on oil crops. with the help of similar future studies in which vermicompost and other organic fertilizers are compounded, a humanand environment-friendly organic production can be realized by increasing the yield as well as the quality.

Gul, Volkan
Because of sunflower is well adapted to the conditions of all region types, it ranks the first in terms of vegetable oil production in our country. The content of fatty acids that determine the quality of sunflower oil is affected by factors such as genotype and environment, especially climate and soil struc-ture. This research examines the oil and fatty acid ratios of sunflower grains grown on a producer basis and presented to the market in 2015 in Samsun (Bafra, Vezirkopru and Havza), Amasya (Merzifon), Corum (Center) and Tokat (Turhal) in the Middle Black Sea Region selected according to the density of oil sunflower to determine the quality of oil. According to the results of the research, average fat ratio was found to be between 41.57% and 45.67%, palmitic and stearic acids, which are basic saturated fatty acids, between 5.65% and 6.44% and from 3.84% and 4.81% linoleic acid (omega 6), linolenic acid (omega 3) and oleic acids (omega 9), which are unsaturated fatty acids, were found between 50.33 and 63.42%, 0.24 and 0.29% and 25.32 and 37.50%, respectively. These results indicate that the sun-flower seeds cultivated in the Amasya-Merzifon re-gion are at the forefront due to their oil quality char- A cteristics.
