This research was carried out to see the effects of organic farming and determine the yield and some pomological characteristics of apricots in Isparta, Turkey. Isparta province which is located in the west Mediterranean part of Turkey has also gained importance in terms of especially organic apricot production. Two apricot varieties (Hasanbey, Alyanak) were grown with organic farming practices in this study. These two varieties are table types apricot varieties commonly grown in Turkey’s one of the world's major producers. In this research, pomological characteristics 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 activity were also determined. Hasanbey cultivar had higher yield value (66.21 kg/tree) than Alyanak (45.71 kg/tree) cultivar. At the same time the total phenolic content of Hasanbey (307.12 mg GAE/100g) variety was determined higher than Alyanak (175.91 mg GAE/100g). Antioxidant activity of Alyanak and Hasanbey were determined as 32.86 mg/ml IC₅₀ and 17.37 mg/ml IC₅₀ respectively. In terms of observed characteristics, Hasanbey cultivar was found to be prominent in Isparta. It can also been recommended for other places similar to Isparta ecological conditions (highland climate).
