Abstract
This research was conducted at the orchard of the tissue culture date palm station / Ministry of Agriculture that is located in the desert region of Al-Najaf Al-Ashraf Governorate/ Iraq during the years of 2013 and 2014 on sixty young trees of three years old of date palm for Barhee cv. The aim was to study the effect of humus organic acids on improving the vegetative growth of date palm witch grown in the desert regions and its role to give the changes in some physical and anatomical properties of the leaves . Ten treatments of different concentrations of humic and folvic acids by adding them as solution to the soil around the palm or sprayed them on leaves monthly for sixteen months from 6 / 2 / 2013 with using two type of irrigation water ( well water or Euphrates river water ) . The results were measured in three dates at 1/6/ 2013 , 1/11/2013 and 1/6/2014 . The results indicated that the humus organic acids treatments caused a significant increased in the averages of number of new leaves, length of leaf and pinnate , and significantly reduction the cuticle layer thickness in the leaves parameters at the second and third calculated dates that superior in the treatments ; Humic acid 12 % ( 15ml. ) , humic acid 80 % ( 6 gm. ) soil application or humic acid 18 %+ fulvic acid 3 % ( 6 or 9 ml. ) foliar sprays. The results also induced that irrigated with the well water caused significantly decreased on the averages of number of new leaves, length of leaf and pinnate also caused significantly increased in cuticle layer thickness . On the other hand, irrigated with the river water gave opposite of this results in all characteristics. The interaction between the treatments of humus organic acids with the well or river water caused significantly influenced on the parameters that most obtained at the second and third calculated dates which surpassed by the treatments ; Humic acid 12 % ( 15ml. ) , humic acid 80 % ( 6gm. ) soil application or humic acid 18 %+ fulvic acid 3 % ( 6 or 9 ml. ) foliar sprays as caused significantly increased in the averages of number of new leaves , length of leaf and pinnate , while significantly decreased in layer thickness of cuticle.
