The study was conducted during the two growing seasons (2019 and 2020) on grape vines in the Lubnanian Halawani and Kamali varieties in the orchard of grapes cultivated in 2016 inthe Department of Horticulture and Landscape Design - College of Agriculture- University of Tikrit,. An experiment was including three factors, the first was considering the varieties (Halawani and Kamali), and the second factor was the addition of Agricultural Sulfur (S )to the soil, at three levels, S0 (no sulfur added), S1 (250 g. Grapevine-1), S2 (500 gm. Grapevine-1). The third factor was spraying the leaves withSuper Docson nutrient at three different concentrations: P0 (spraying with distilled water), P1 (spraying with the Super Docson nutrient with three concentrations: P0 (spraying with distilled water), P1 (at a concentration of 1.2 ml. L-1 water), and P2 (at a concentration of 2.4 ml. L-1 water), and the Super Docson nutrient sprays which contains the diffuser (Tween 20) was applied in early morning and until complete wetness A factorial experiment was carried out with the split plot system according to the Randomized Complete Block Design (RCBD), where the varieties took the main plates, while the sulfur and nutrient treatments and their interactions were randomly distributed on the sub plot by three replications and the results showed: The Halawani variety superiority in most of the studied traits at the level (250 g. Vine-1) and the concentration (1.2 ml. L-1), except for the concentration of the element phosphorus in the leaves, where the Kamali variety was superior in this characteristic as perfection at the same level and concentration. The double interaction between sulfur and nutrient exceeded the level (250 g. Vine-1) and the concentration (1.2 ml. L-1) in most of the studied traits and for both seasons. As for the triple interaction between the variety, sulfur and nutrient, the Halawani variety was superior at the level (250 g. Vine-1) and concentration (1.2 ml. L-1) in most of the studied traits for both seasons.

The study was conducted during the two growing seasons (2019 and 2020) on grape vines (Halawani and Kamali varieties) in the vine yard of the Department of Horticulture and Landscape Design- College of Agriculture- Tikrit University. The vines cultivated in 2016. The experiment was conducted with three factors, the first, is the varieties (Halawani and Kamali), the second is agricultural Sulfur (S) with three levels, (S0:, S1: 250 g. vine-1,and S2: 500 gm. vine-1) and the third factor is the spraying of “Super Docson” nutrient solution with three concentrations (P0 : spraying with distilled water, P1 : 1.2 ml. L-1 , P2 : 2.4 ml. L-1). The spraying was done in Early morning to until complete wetness. The experiment was carried out with the split plot system in Randomized Complete Block Design (RCBD). The varieties took the main plots, while the sulfur and nutrient treatments were randomly distributed on the sub plots, by three replications and the results showed That, the Halawani variety was excellence on Kamali in most studied traits, and which included (leaf area of vine(m2.vine -1) , main branch length(cm), leaf chlorophyll content, vine yield(kg) and total yield(tons.ha-1). And the results showed excellence at concentrate 2.4 ml. L-1 for nutrient and at level 500 g for sulfur in most studied traits.
