This Study was conducted at private apple orchard located at AL-Rashidia region in Mosul , Iraq , during the season of 2008 . To study the effect of different levels of Nitrogen fertilization (0,60,120 and 180KgN.h-1 and foliar application of Boron (0,50,100 and 150mgB.l-1) as boric acid H3BO3 (17%B) on fruit set , vegetative growth and some quality and quantity of yield characteristics of Anna apple cultivar.The results showed response of apple trees to nutrient treatments especially with using 120KgN.h-1 which caused increased on fruit set, leaf area, total chlorophyll in the leaves, TSS in fruit, fruit weight and tree yield, while this treatment caused a significant decrease in total acidity in fruit. In the same direction of results when foliar application with 100mgB.l-1 for these characteristics. The best results of growth and quntity Anna, apple yield and quality were obtained by interaction between application containing 120KgN.h-1 + 100mg B.L-1.
