Abstract
This experiment was carried out at a private palm farm located in Great Musayib enacted / Babylon province on Barhi dates palm trees Phoenix dactylifera L. cultivar to determine the effect of spraying of chitosan and addition of both organic fertilizers and amino acids and seaweed extract in some vegetative traits (number of leaves, the circumference of the trunk and offshoots number) and leaves content (chlorophyll , dry weight and Proline) by spraying the chitosan at concentrations of 5 ml. l-1 and 10 ml.L -1 and the addition of both organic fertilizer and amino acids and seaweed extract at concentrations (1, 2) kg.tree -1 and (3 , 6) ml . L - 1 and (4, 8) ml l -1 respectively. Each treatment replicated five times with a factorial experiment using RCBD, one date palm for each experimental unit.The following are the main findings, The effect of chitosan spraying significantly increase the vegetative properties of the offshoots , the concentration 5 ml.l-1significant increases the number of weakness, trunk circumference and offshoots number, with 13.3 tinea, 31.9 cm, 3.09 offshoot sequentially. Spray 8ml.L-1(S2)of seaweed extract was significantly superior than control treatment and gave leaf chlorophyll content of 31.88 mg.g-1, leaf dry weight of 48.90 %. While the lowest results were in the control treatment, except the leaves proline content.
Highlights
Date palms (Phoenix dactylifera L.) are belonging to the family Arecaceae
Balaket and AlHimidawi [7] Mentioned that the humic organic acids treatments caused a significant increases in the leaves content of total chlorophyll, carbohydrates and total protein caused significantly decreases in the leaves content of proline amino acid compared with the control treatment in his study on Barhee date palm trees
MATERIALS AND METHODS This experiment was carried out at a private palm farm located in Great Musayyib enacted / Babylon province by use Barhi dates palm trees Phoenix dactylifera L. cultivar to determine the effect of spraying of chitosan and addition of both organic fertilizers and amino acids and seaweed extract in some vegetative traits
Summary
Date palms (Phoenix dactylifera L.) are belonging to the family Arecaceae. Date palm is one of the oldest trees known to humans, dating more than 4000 years BC and was cared for by the Babylonians and Assyrians [15, 25]. These findings were agreed with Ahmed et al [6] who found that when palm trees were sprayed with some amino acids, they improved the vegetative growth of olive trees [16]
