The study was conducted at the Agricultural Research Station of the College of Agriculture, University of Basrah, in Karma Ali area during the agricultural season 2022-2023 to study the effect of foliar spraying with different concentrations of ascorbic acid (0,50,100) mg L-1 and with different concentrations of nano silicon (0,37.5,75) mg L-1 and the interaction between them on the quantitative and qualitative yield of the Burren potato cultivar. The results showed that spraying with ascorbic acid at a concentration of 100 mg L-1 was significantly excelled in increasing the total yield and marketable yield, reducing the non-marketable yield, increasing the percentage of dry matter, starch, and specific gravity of tubers, and both concentrations were significantly excelled in increasing the tubers' vitamin C content. Also, plants sprayed with nano-silicon were significantly excelled at a concentration of 75 mg L-1 in increasing the total yield and marketable yield, the percentage of dry matter, starch, and specific gravity, and the tubers' vitamin C content, and both concentrations were significantly excelled in the percentage of total soluble solids. The interaction between the two study factors showed a significant effect on all quantitative and qualitative yield traits studied.
