The study was conducted at the Agricultural Research and Experiment Station of the
College of Agriculture / University of Kirkuk on (1-9-2021 until 1-5-2022), the study included
two factors, the first three varieties of date palms (Al-Shuwathi Al-Asfar, Al-Khadrawi and Al-
Khastawi) and the second factor five concentrations of Salicylic acid and the organic nutrient
(dipr chlorophyll) and the concentrations were as follows: (0 mg.l-1 and 150 mg.l-1- salicylic
acid and 300 mg.l-1- salicylic and 300 mg.l-1- dspr chlorophyll and 600 mg.l-1-dspr
chlorophyll). . The experiment was designed according to a randomized complete block design
RCBD as a factorial experiment with two factors according to a split system and with three
replications, and the data were analyzed according to Duncan's polynomial test at a probability
level (0.05). It gave a rate of (2.37% and 14.84%) respectively, while the Khadrawi cultivar
excelled in the percentage of potassium in wicker and the wicker content of carbohydrates,
which amounted to (1.29 and 3.72)%, respectively, while the Khastawi cultivar had the highest
rate. The ratio of carbohydrates/nitrogen reached (218.80). Also, the results showed that the
concentration of (600 mg.L-1 of dspr chlorophyll) exceeded in all the studied chemical
characteristics.
Whereas, the interaction treatment between (Yellow Shuwethi cultivar and a
concentration of 600 mg.L-1 of dspr chlorophyll) showed a significant superiority in nitrogen,
phosphorous and protein ratios in wicker, which amounted to (3.61, 0.13, 22.59)%, respectively,
while it gave an interaction treatment between (Al-Khadrawi cultivar and the concentration of
600 mg.l-1 of despar chlorophyll) significantly outperformed the potassium content of wicker
as it reached (1.99)%, while
