This investigation was carried out during the seasons 2013 and 2014 on 13 years old trees of Hindi Besinnara cv. Mango trees, to evaluate the effect of deblossoming date on the early panicles of Hindi Besinnara cv. on flowering and fruiting attributes at private orchard located at Cairo – Ismailia desert road. Five dates of panicle deblossoming were used: removing all panicles of tested trees at the first week of January, removing all panicles of tested trees at the third week of January, removing all panicles of tested trees at the first week of February, removing all panicles of tested trees at the first week of February and control trees (un deblossoming trees). Results indicated that removing the early panicles at the third week of January, at the first week of February and at the third week of February increased total number of axillary panicles per tree significantly than the control. On the other hand all dates of deblossoming early panicles decreased panicles length compared to control, both of removing early panicles at the first and third week of February increased the secondary branches of panicles per panicle compared to the other treatments. Number of emerged axillary panicles per removed panicle increased with significant difference with deblossoming at the first week of February compared to the other dates of deblossoming. Removing the apical panicles of Hindi Besinnara cv. Mango trees at the first and third week of February improved significantly the perfect flowers percentage, while removing early apical panicles at the first week of February was achieved the highest percentage of fruit retention, while both of control trees and removing the early panicles at the first week of joinery decreased this percentage sharply. Moreover, removing the early apical panicles at the first week of February enhanced the Hindi Besinnara cv. fruit trees with significant difference compared to the other dates of panicles removing.
