The current study was done in 2022 seasons to study the influence of foliar application by moringa leaf extract at (2, 4, and 6 ml.l-1), garlic cloves extract (5, 10, and 15 ml.l-1), and turmeric extract at (5, 10, and 15 ml.l-1) plus the control treatment on some minerals content in the “Salakhani” pomegranate leaves grown in a private orchard situated in Halabja Governorate, Iraq. Thirty healthy trees, uniform in their vigor and with no visual insufficiency symptoms, were selected, each tree as an experimental unit by utilizing a simple randomized complete block design. The results revealed that the spraying with the most doses of moringa leaf extract, garlic cloves, and turmeric significantly increased the N, K, Mg, Ca, Zn, Fe, and B in the leaves content of pomegranate compared to the control. The effect of the studied plant extracts regarding the P content in pomegranate leaves compared to the control expressed insignificant differences. Generally, the leaf content of N, K, Mg, Ca, Zn, Fe, and B increased with increasing concentrations of moringa leaf extract, garlic cloves, and turmeric. The highest concentration of them gave the highest value of studied minerals content. Thus, it can be recommended to use these plant extracts as an alternative to chemical fertilizers.
