Changes in Qualitative and Quantitative Traits of Anatolian Chestnuts (Castanea sativa Mill.) Fruit Due to Balanced Macro Fertilization

The aim of this study was to determined effect different doses N: P: K applications on fruit yield and some quality traits in Anatolian chestnut Bursa (Turkey) ecological condition during 2013 2014. In the research, triple experimental zones were a 20-year-old orchard. Each these consisted 30 trees. As treatments, 1.1, 2.2, 3.3, 4.4 lb N tree-1 (N application zone; NAZ), 0.55, 1.65, 2.2 P (P PAZ), (K KAZ) applied except for control dose. fertilizer by mixing cm depth tree canopy soil April. According analyses collected, nitrogen, phosphorus, potassium affected 30, 31, 27%, respectively. Total protein increased fastest at nitrogen application's zone (NAZ) an average 14% rate. highest increasing carbohydrate, starch, invert sugar recorded as 20, 24, 18%, respectively zone.
