Modelling sustainable salt water management under deficit irrigation conditions for melon in Spain and Brazil

摘要

BACKGROUNDIn water scarcity areas the use of saline water for irrigation is a common practice. In this study, experimental data from two two-year melon tests were collected for the calibration (2004 Yellow Melon' (YeMe) type) and validation (2002 YeMe, 2005 and 2006 Piel de Sapo' (PiSa) type) processes in melon crop simulation under deficit irrigation conditions using salt water. The simulations were carried out for Castilla-La Mancha (Spain) and Ceara (Brazil) using the MOPECO model, which includes optimized regulated deficit irrigation (ORDI) methodology. The objective was to determine the most suitable irrigation strategy for both areas.
