Özet
Most of the irrigated areas are faced with waterlogging and salinity problem, whose irrigation schedules differ from a normal irrigation program. Capillary rise and subsequent salinity should be considered in these problematic areas. In this research, scheduling a new sustainable irrigation program was simulated for Konya-Cumra Irrigation District with shallow and saline water table conditions. The order of capillary losses from soils in magnitude from larger to smaller was loamy, sandy and clayey soils. Critical water table depths in terms of salinisation risks due to capillary rise were 1.0, 2.5 and 3.0, respectively for the sandy, loamy and clayey textures. For the chosen crop pattern, cereal-cereal, a considerable amount of salt accumulation was simulated during a three-month fallow period. With new irrigation scheduling, taking the capillary rise into account, not only a sustainable scheduling program is suggested but also a 10 % irrigation water is saved. The suggested program assumes the existence of a drainage system.
