This study was conducted in a private grape vineyard during the year 2019, was located in Tapalw village, Lailan district, Kirkuk province, Iraq. The was to study the effect of spraying four levels of the moringa leaf extract (0, 15, 30 and 45) g.L-1 and licorice root extract (0, 2.5, 5 and 7.5) g.L-1 on some growth characteristics and yield of grape (Vitis vinifera) cv. Halawany. Spraying of the extracts were applied in three times: the first spraying was before flowering on 24/4/2019, the second, a week after berries set on 5/5/2019, and the third, two weeks after the second spray on 22/5/2019. The results showed that 15 g.L-1 of the moringa leaf extract significantly superior on the control treatment in the leaf area, chlorophyll content of leaf, total yield, number of clusters per vine, an average of cluster weight, berries weight without a structure, structure weight without berries, and length and width of the cluster. However, spraying with the extracted moringa leaves at level 45 g.L-1 superior significantly on the control treatment in the total soluble solids, total sugars and the anthocyanins content in berries peel. Spraying with the extracted of licorice root extract at level 2.5 g.L-1 resulted in a significant increase in leaf area, chlorophyll content of leaf and total soluble solids. In addition, spraying at level 7.5 g.L-1 of licorice root extract had a significant influence on increasing the total yield, number of clusters per vine, average of cluster weight, berries weight without structure, structure weight without berries, and cluster length and width, and anthocyanin content of berries peel.
