Özet

This research aimed to examine the effects of organic farming on apricot cultivation and to determine the yield and certain pomological characteristics of apricots produced in Isparta, Turkey. The city of Isparta, which is located in the Western Mediterranean part of Turkey, has also gained importance in terms of organic apricot production. Two apricot varieties (Hasanbey, Alyanak) were grown by means of organic farming practices in this study. These two varieties are table types of apricot varieties commonly grown in Turkey, one of the world's major producers. In this research, pomological characteristics such as fruit size (fruit height, fruit width, fruit weight, fruit length), fruit firmness, pH, total soluble solid (TSS) content, titrable acidity (TA) and yield values were determined. Total phenolic and antioxidant activities were also identified. The apricot cultivar Hasanbey had higher yield value (66.21 kg/tree) than the cultivar Alyanak (45.71 kg/tree). Besides, the total phenolic content of Hasanbey (307.12 mg GAE/100g) variety was determined to be higher than that of Alyanak (175.91 mg GAE/100g). Antioxidant activities of the Alyanak and Hasanbey varieties were determined as 32.86 mg/ml IC50 and 17.37 mg/ml IC50, respectively. Based on the characteristics examined, the Hasanbey variety is considered more efficient for the Isparta region and is therefore recommended for other places with similar ecological conditions (highland climate).
