Abstract :This research was performed to determine the effects of potassium applied on the soil to different doses on the yield and yield components of sweet chestnut grown in conditions in the Bursa province in 2012 and 2013. In this context, 0, 500, 1000, 1500 and 2000 g K tree-1 doses were applied to the tree canopy soil at 0-30 cm depth in April. According to the results of the study, the highest fruit yield, total protein, and sugar were recorded averagely 26 kg tree-1, 10.7 and 13.7 g 100 g-1 respectively in 1500 g K tree-1 dose in application years. The highest starch content in fruit was determined as average 34.5 g 100 g-1 in 1000 g K tree-1 dose. As a result of this research, the amount of potassium fertilizer to be applied to the Sarıaşılama variety of chestnut trees at the age of 20 years were determined as 1500 g K tree-1Keywords : Chestnut (Castanea sativa Mill.), potassium, yield, quality
