Methods are needed to minimise the volume of water requiring disposal. Shallow groundwater may represent a substantial resource by capillary rise in flat, low-lying areas, but may also represent a threat to sustainability where salinity is high. Experiments in a laboratory conditions aimed to elucidate irrigation management practice under saline condition and to develop a root uptake model under both osmotic and matric stress. The extraction of soil water and groundwater by spinach crop was measured in two lysimeters. The water table depths 1 were 0.6 and 0.9 m below the soil surface and two salinity levels, 0.4 and 8 dS m(-1), were used for each depth. The overall experiments showed that the ground water contribution was within the range of 26-72% of the total water use. There is a reasonable agreement between measured and estimated values.en10.17660/ActaHortic.2002.573.24info:eu-repo/semantics/closedAccessSalinityWaterloggingSpinachModellingIrrigation ManagementConference Object573211217N/AWOS:0001767323000242-s2.0-84879429674Q4
