THE EFFECTS OF SUB-IRRIGATION ON SOIL SALINITY BUILD-UP IN SEMI-ARID CLIMATIC CONDITIONS OF IRAN

摘要

This experiment was conducted to evaluate the effect of water tablemanagement (WTM) on soil salinity distribution pattern in rhizospere andsoil profile. The irrigation treatments comprised three sub-irrigation systemsof 30 (WT30), 50 (WT50), and 70 cm (WT70) water table from soil surface.A free drainage (FD) conventional irrigation system was also applied ascontrol. All treatments were arranged in a complete randomized block design
