Type: article
Abstract: To investigate the impact of adding organic acid (humic acid) and spraying, the experiment was carried out in the palm grove at the Agricultural Research and Experiment Station at the Sayada site of the College of Agriculture/University of Kirkuk/Republic of Iraq from 6/15/2022 to 4/15/2023. Three different types of date palms received the NPK compound fertilizer treatment. Al-Khastawi, Al-Khaddrawy, and the yellow Shwathi. Three replications of the factorial experiment were conducted using the RCBD and split plot designs, respectively. Duncan's multiple limit test was used to assess the data at the probability level (0.05). The interaction treatment between the treatment and the treated variety T5V2 (NPK nanocomposite fertilizer and the Khestawi variety) was superior in the percentage of the wicker content of carbohydrates, nitrogen, and chlorophyll, reaching (8.19%), 2.02% 30.33 mg gm -1 fresh weight) respectively. The concentration of (1.5 g liter-1) of NPK nanocomposite fertilizer (T5) affected all the studied chemical properties. The yellow Shuwathi cultivar outperformed the Khastawi and Khadrawi cultivars in the treatment of T5V1 (nano compound fertilizer NPK). The percentage of phosphorus and potassium in the vine reached (0.97, 0.91%), respectively. Wicker's potassium content as a percentage reached 0.74%.
