 Optimization model for on-farm irrigation management of Mediterranean greenhouse crops using desalinated and saline water from different sourcesJ. Reca, C. Trillo, J.A. Sánchez, J. Martínez and D. Valera Agricultural Systems, 2018, vol. 166, issue C, 173-183 Abstract: Desalination is becoming a competitive alternative for supplying quality water to irrigation districts in dry areas. However, its acceptance level among farmers is often low due to its higher price, the need for additional fertilization, and the misconception that it would negatively affect yield and crop quality. This work presents a decision support system that would help them to make irrigation management decisions regarding the optimal combination of saline and desalinated seawater (DSW), which would provide maximum economic profit. The model has been specially designed for Mediterranean greenhouse cropping systems. The proposed model was validated by applying it to a real watermelon crop which was experimentally monitored. A sensitivity analysis was then conducted in order to analyze the effect of different limiting factors on the optimal combination of water and the optimal profit for farmers.
