Abstract

The experiment was carried out during 2009 - 2011 period under the Yalova location. The aim of this experiment to determine with different nitrogen doses (0, 30, 60, 90 g tree-1) and application times (Application 1: It starts in early spring before the buds burst and finish 4045 days ago from harvest, Application 2: It starts in early spring before the buds burst and finish 40-45 days ago from harvest and postharvest foliar nitrogen application, Application 3: It starts after blooming and finish 40-45 days ago from harvest, Application 4: It starts after blooming and finish 40-45 days ago from harvest and postharvest foliar nitrogen application) effects on fruit mineral composition on Golden Sel-B apple cultivar. The experiment was designed according to randomized block design with three replication. According to results increasing doses of nitrogen increased the nitrogen and copper content and decreased calcium content but did not influence the phosphorus, potassium, magnesium, iron, manganese, zinc and boron content of fruits. Nitrogen application times were non-significant for mineral content of fruits
