Abstract

The present research is conducted during the years of 2013 and 2014 , sixty young date palm trees of three years old were selected for Barhee cv. which propagated by tissue culture and that cultivated in the orchard of tissue date palm station / Ministry of Agriculture that is located in the desert region of Alnajaf Alashraf Governorate . The aim was to study the effect of humic organic acids on leaves content of some Physiological and Nutrition compound . Ten treatment of different concentrations of humic and folvic acids by the addition as solutions to the soil around the trees or by spraying on the leaves at interval of sixteen consecutive months started 6 / 2 / 2013 with using two type of irrigation water ( well water or Euphrates river water ) . The measurement was done three times on 1/6/ 2013 , 1/11/2013 and 1/6/2014 . The results indicated that the humic organic acids treatments caused a significant increasing in the leaves content of total chlorophyll , carbohydrates and total protein also caused significantly decreased in the leaves content of proline amino acid that superior in the treatments ; humic acid 12 % (15ml./L.) , humic acid 80 % ( 6gm./ L.) as soil addition and humic acid 18 %+ fulvic acid 3 % ( 6 or 9 ml./ L.) as foliar application.
