Root system development is very importance for highest soybean (Glycine max L.) grain yield, especially under arid and semiarid conditions. In order to tillage system management (TSM) for achieved to the optimum yield of soybean in dry-farming conditions, this experiment was carried out using by a factorial design with four replications. The factors were till-systems including no-tillage (NT), minimum tillage (MT), full tillage (FT) and conventional tillage (CT) and were studied the effects of tillage system on root growth and grain yield in soybean. The root development features were root length and root diameter at 5 soybean growth stages. The root length was increased under no-tillage than under conventional tillage and the root diameter wasn’t significantly affected by the tillage systems. The best of root system development in soybean was achieved during the stem elongation stage under no-tillage system. Therefore, monitoring soybean root development showed that tillage system management is very important in dry-farming, because in arid and semi arid weather the water resources are limited, so no-tillage system is a good system for farming in these conditions.
