Abstract: The aim of this study was to determine the effect of growing tomato on different root stocks on its growth and yield. In this study, tube grafting method was adopted since it has been widely used with high percentage of success. Tomato (Lycopersicon esculentum Mill.) cultivar Cecilia F1 was grafted using tube grafting method on three rootstocks, Beaufort, He-man and local Syrian tomato which were grown under glasshouse and fertilized according to the routine fertilization program with macro and micronutrients in ASTRA farms, Tabuk, north-west of Saudi Arabia. Plants produced from grafting Cecilia F1 scion on Beaufort rootstock were the tallest (37.56 cm) and had the greatest number of leaves (7.22) and stem diameter (4.92 cm). Six weeks after of grafting seedling leaves contents of Ca, Na, Mg, Fe and K increased and while the roots contents were not affected. Chlorophyll a and carotenoids significantly increased. The productivity of grafted tomato planted in glasshouse increased significantly and had reached up to 21%. Grafting also increased Total Dissolved Solids (TDS) and decreased the amount of lycopene in all grafts but β-carotene increased in Cecilia on Beaufort (5.46 mg kg-1) and decreased in both Cecilia on He-man and Cecilia on local Syrian tomato fruits. It is concluded from this study that grafting significantly affected tomato growth and yield depending on the different rootstocks utilized.
