چکیده
Salinization of soil is primarily caused by capillary rise from saline shallow groundwater or
application of saline irrigation water. In this investigation, the transient state analytical model
was modified to predict water uptake from saline shallow groundwater, actual crop
evapotranspiration, soil water content, dry matter, seed yield and soil salinity under different
saline groundwater depths, irrigation water salinities and deficit irrigation for quinoa.
Considering the effect of salinity on soil saturated hydraulic conductivity and maximum root
depth in presence of shallow saline groundwater, the model resulted in good agreement between
the measured and predicted saline groundwater uptake, soil salinity increase at different
groundwater depths (300-800 mm) and water salinity (10-40 dS m-1). Therefore, the modified
model is applicable for quinoa yield and soil salinity prediction and it could be a valuable tool
for soil salinity management in presence of shallow saline groundwater. Furthermore, prediction
of quinoa yield by the modified model can be used for better irrigation water salinity
management under different saline groundwater depths, irrigation water salinities and deficit
irrigation.
