In the Mediterranean region, careful management of water and nitrogen utilization is required to achieve high crop yields in a sustainable and economic way. Prediction models are useful tools for deriving site/region–specific optimum management strategies for irrigation and nitrogen use. Yield-SAFE, a simple and robust model for growth and resource use in agroforestry systems, simulates crop yi...

Sustainable water use is one of the greatest challenges of irrigated agricultural systems. This study presents the results related to the agronomic and physiological response to the deficit irrigation of almond trees (Prunus dulcis DA Webb Mill cv. Guara) under semiarid Mediterranean conditions in the Guadalquivir river basin (SW Spain). Two deficitirrigation strategies were tested: i) regulate...

Mango (Mangifera indica L.) is broadly grown in tropical regions and can also be cultivated irrigated subtropical semi-arid areas; however, water shortages are a serious problem the latter region. Among biotic abiotic factors, supply one of most crucial elements that determine productivity. The allocation will an ever-increasing source pressure because vast agricultural demands under changing c...

Improving water efficiency in irrigated agriculture is a priority for better environmental and economic performance. It can be achieved by reducing the amount of water used and optimizing the timing of application. Among numerous methods, hybrid biophysical/decisional simulation models are effective tools for evaluating and comparing irrigation strategies under different weather conditions. How...

A dynamic simulation model of salt accumulation on irrigated lands is presented. The original version of the model is part of a large-scale socio-economic model of irrigation-based regional development. The model introduced in this paper is a systemic one in the sense that it integrates four major sub-processes of rootzone salinization: irrigation, drainage, groundwater discharge and groundwate...

Salmonella enterica is one of the major food-borne pathogens associated with ready-to-eat fresh foods. Although polluted water might be a significant source of contamination in the field, factors that influence the transfer of Salmonella from water to the crops are not well understood, especially under conditions of low pathogen levels in water. The aim of this study was to investigate the shor...
