The aim of this study is to observe the effect of irrigation water of different salinity level on root development of tomato plant and carried out Atatürk Soil, Water and Agricultural Meteorology Research Institute`s Greenhouses. Irrigation water (T1: 0.38 dS m-1 - T2: 5,0.dS m-1) with two different amounts of salt was used in the study and the root development of the tomato plant was examined at four different depths (0-25, 25-40, 40-55, 55-70, 70-90 cm) were monitored with the aid of a minirhizotron camera. The obtained root images are analyzed with the help of the RootSnap program to calculate the root quantities in 5 different depths as a percentage.

As a result of the research, the root growth of tomato plant with T2 irrigation water was adversely affected by salt accumulation in the soil with high salt content (0-25, 25-40 cm) and accordingly root percentage was low. In the low-salt lower layers (40-55, 55-70, 70-90 cm), the percentage of root was increased because the salt accumulated in the soil was low . In T1 irrigation water, the percentages of roots were obtained in close proximity in each layers, since that would not affect root development and water uptake negatively.
