This study was carried out to determine effect of the potassium fertilizer rate on yield and fruit quality of day-neutral strawberry cultivar 'Albion' during 2013-2015 years. Frigo seedlings of Albion cultivar were planted in June 2013. In the experiment, 0-5-10-15 kg/da K2O fertilizer was applied and identified as K-0, K-5, K-10 and K-15. Fruit weight, fruit length, fruit width, yield per plant, total soluble solid (TSS), titratable acidity (TA), pH, total phenolic and anthocyanin were determined. Applications exhibited a range of 10.95-27.94g for fruit weight, 24.95-37.91mm for fruit width, 34.44-52.18mm fruit length, 3.87-4.26 for pH, 7.00-8.10% for total soluble solids and 0.97-1.20% for titratable acid. Total phenolic content was observed in 650.28-900.02mg (Gallic acid equivalents (GAE)/100g) and anthocyanin content was observed 155.06-204.18mg/100g. We can recommend the K-10 and K-15 applications according to obtained data in our research for producers.
