This experiment was carried out in a private vineyard located at Wazha village in Shar-Bazher district, Sulaimani governorate, Kurdistan region, Iraq, the elevation of the orchard is 974 m above sea level, during season 2017, to study the effect of foliar application of three concentrations of Iron (FeSO4, 20.5 % Fe) (0, 75, 150 ml.L-1) and three concentrations of Microgreen fertilizer (Microgreen) (0, 0.5, 1 g.L-1) on grapevine cv. Khoshnaw, 20 years old. The results shows that spraying of Iron or Microgreen had a positive effect on leaf area, leaf fresh and dry weight, total chlorophyll percentage, number of cluster, cluster weight, yield as well as berry length and diameter and weight and size of 100 berries, as such TSS and total sugar as compared to check treatment, whereas the same traits lead to decrease in total acidity percentage. The treatment combination had no effect on number of clusters per vine, juice percentage and juice density. The interaction between Iron and Microgreen at 150 m.L-1 Iron and 1 g.L-1 of Microgreen gave the highest values of all growth parameter and yield and grape characteristics except total acidity that obtained in the control.
