الملخص EN

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
