The present investigation was undertaken during the selected two successive seasons of 2012 and 2013 on 12 years old Anna apple trees (Malus domestica, Borkh) budded on Shobra khan apple rootstocks. The selected trees were planted in a private orchard in Tanta, Gharbia Governorate, in clay soil and spaced at 3 x 4 meters apart. The trees were trained as open-vase form, irrigated by Nile water using surface irrigation (basing irrigation) system. The selected trees received the same horticultural practices and fertilization regime. The experiment was conducted on 60 apple trees Anna cv . in both seasons, ten  treatments were carried out, each treatment replicated three times considering each two trees as a replicate using a split plot design , Humic  and fulvic acids were added  at 4 liter/fed. and  mix  with   calcium nitrate ( 0.4 %) , zinc sulphate ( 250 ppm)  and borax  ( 20 ppm)  as foliar spray  at  five  development stages  (at bud burst , fruit set, at the beginning  of false  coloring , at the  end  of false  coloring   and at the  beginning  of true  coloring. Sprayed trees with fulvic acid at 4 liter/fad.  and mixture of  calcium nitrate (0.4 %) , zinc sulphate ( 250 ppm)  and borax  ( 20 ppm) at  bud burst ( T6) significantly increased  both leaf  surface area and  shoot length in both seasons. While T7  sprayed trees with fulvic  acid at 4 liter/fed. and mix., calcium , zinc and boron after fruit set recorded the highest values of fruit number/tree, fruit weight and fruit volume, soluble solid content, soluble  solid content /acid ratio and total sugars and decreased  specific gravity in fruits  in both seasons . fruit height and diameter were increased with  sprayed trees  with …
