520 _aThis investigation was carried out during two successive seasons (2012-2103 and 2013-2014) in a private orchard at Cairo Alexandria Desert Road, 62 km, Egypt on 9 years old 2Keitt3 and 2Tommy Atkins3 mango trees (Mangifera indica .L) budded on white Sukary seedling rootstocks to determine the most appropriate level of pruning and the most suitable rates and dates for the addition of nitrogen fertilizers and their effect on vegetative growth aspects, yield and fruit quality attributes as well as leaf content of nitrogen, phosphorus and potassium of Keitt and Tommy Atkins mango cultivars.The treatments were divided to three factors as follows: The first is type of cultivar: 2Keitt3 and 2Tommy Atkins3 mango trees; the second is levels of pruning after harvest in September by removing 10% or 20% or 30% of the total vegetative shoots in addition to control (without pruning); and the third is different rates of nitrogen fertilizers application which divided to the different stages of growth of the plant as follows (50+20+30), (50+30+20), (0+50+50), (50+0+50) in addition to control (fertilization program recommended in the farm).The results indicated that Tommy Atkins mango cultivar with removing 30% of vegetative growth under N fertilization rate (50+0+50) enhanced number of growth cycles and the most studied characters of vegetative parameters. On the other hand, Keitt mango cultivar with removing 20% of vegetative growth under N fertilization rate (50+0+50) improved fruit quality attributes such as physical and chemical fruits characteristics and leaves nutrient content in the two seasons of this study
