Deficit Irrigation Using Saline Water of Fruit Trees under Water Scarcity Conditions of Southern Tunisia

Application of the SWAP model to simulate water-salt transport under deficit irrigation with saline water

The agro-hydrological Soil–Water–Atmosphere–Plant (SWAP) model was calibrated and validated to simulate water–salt transport based on field experiments in an arid region of China. The simulation results show lower soil water content but higher salt concentration under deficit irrigation. Soil water and salinity below 95 cm at 80% evapotranspiration (ETc ) treatments and 65 cm at 60% ETc treatme...

Modification of transient state analytical model under different saline groundwater depths, irrigation water salinities and deficit irrigation for quinoa

Salinization of soil is primarily caused by capillary rise from saline shallow groundwater orapplication of saline irrigation water. In this investigation, the transient state analytical modelwas modified to predict water uptake from saline shallow groundwater, actual cropevapotranspiration, soil water content, dry matter, seed yield and soil salinity under differentsaline groundwater depths, i...

Soil genetics as affected by topography and depth of saline and alkali ground water under semiarid conditions in southern iran

growth and flowering of two tuberose (polianthes tuberosa l.) cultivars under deficit irrigation by saline water

tuberose (polianthes tuberosa l.) is one of the most important bulbous ornamental crops of tropical and subtropical areas. the objective of the present study was to determine the interaction effects of salinity and irrigation intervals on growth and flowering of two important commercial cultivars (‘mahallati’ and ‘dezfuli’) of tuberose (polianthes tuberosa l.). irrigation treatments consisted o...

estimation soil water content under deficit irrigation by using dssat

crop models need more evaluation and study for use in deficit irrigation. the main objective of this paper was to study the efficiency and accuracy of dssat model, in estimating of moisture in the soil profile under two levels of water application¬¬¬ in silage maize field. two irrigation treatments including deficit irrigation (0.7 smd), and a full irrigation (smd) were considered for two years...
