Abstract

This study is conducted in a closed ‘Amasya’ apple orchard located in Sivaslı, Uşak, in order to analyze the changes that occurred due to the usage of chemical and organic fertilizers on some pomological and biochemical features relevant to fruit quality. In the control group, measurements are performed over 30 randomly selected apples with foliar fertilizer (20.20.20) and organic fertilizers (seaweed). Measurements based on the pomological features are as follows: fruit mass is between 157.53 g and 162.37 g; fruit length is between 68.04 mm and 69.68 mm, fruit width is between 71.4 mm and 72.88 mm, while measurements based on biochemical features show that phenolic substance is between 181.82 ppm and 258.18 ppm; flavonoid substance is between 678.00 ppm and 793.33 ppm, and soluble solids content (SSC) is between 14% and 15.83%. As the organic acid content, oxalic acid is measured between 34.67 ppm and 48.33 ppm; malic acid 9625.33 ppm and 10,393.66 ppm; ascorbic acid 88.00 ppm and 117.67 ppm; tartaric acid 1388.33 ppm and 2140.67 ppm; citric acid 787.33 ppm and 1008.33 ppm; acetic acid 719.00 ppm and 995.00 ppm.
