Abstract: 

This research was carried out in the nursery of the agricultural faculty at Tishreen University during the spring period of the agricultural season 2021, and aimed to study the effect of foliar spraying with a group of B vitamins on some growth and productivity indicators on potato plants (Spunta cultivar). The study included eight treatments: spraying the plants with vitamins (B1, B2, B3, B6, B9, B12) individually and a mixture of vitamins (Bmix) at a concentration of 100ppm in addition to the control treatment. The experiment was designed according to complete random distribution with three replications. The results of the study showed the positive effect of treating the plants with all the previous different vitamins compared to the control in all the studied indicators (area and leaf surface index, number of tubers, average weight of the tuber, total production and marketing) with a significant superiority of treatment of plants with a mixture of vitamins (bmix).On all treatments: the leaf area (16575cm2/plant) and its index (7.36), plant height (96.5cm), total production (1816g/plant) and the number of tubers.

Keywords: potatoes, vitamins B, Growth, Production.
