Simulated Crop-water production functions for several crops when irrigated with saline waters

Author: 

Information on crop-water production functions when irrigating with saline waters is required to develop optimum irrigation strategies for various crop. A model was developed to compute these production functions by combining three relationships: yield and evapotranspiration, yield and average root-zone salinity and leaching fraction. The model allows plant-growth adjustement and, therefore evapotranpiration adjustement to root-zone salitinity. Using the model, product functions were computed for several crops. Calculated relative yields ere compared with relative measured relative yields from experiements that had water quantity and quality as variables.
