The study was conducted in a private orchard in Owainat region in Tikrit city of Salah al-Din Governorate - Iraq, during the growing season 2022. To study the effect of adding the organic nutrient Complex-Groop at three concentrations (0, 125, 250) g Tree −1 in two batches, the first on 2/15 and the second on 5/15 – 2022, and spraying with growth regulator of Kinetin at three concentrations (0, 75, 150) ml L −1 with three sprays during the growing season, where the first spray was on 3/15, the second on 4/15, and the third on 5/15 on some characteristics of vegetative growth and yield of Pomegranate trees Salimi cultivar. The experiment was carried out according to the randomized complete block design as a factorial experiment with three replications and two trees for each experimental unit. The results were summarized as follows: The addition of the organic nutrient Complex-Groop at two concentrations of 125 and 250 g Tree −1 resulted in a significant increase in leaf area and chlorophyll content. The interaction between the levels of the organic nutrient and the growth regulator Kinetin significantly affected all the studied traits.
