Victor Sadras is a crop ecophysiologist with interest in the adaptation of crops to environmental stresses, including water deficit, extreme temperatures, nutrient deficit, soil physical and chemical constraints, pathogens and insects. He has measured and modelled aspects of the water, carbon and nitrogen economies of annual (wheat, field pea, chickpea, sunflower, maize, soybean, cotton) and perennial crops (grapevine, olive) in rain-fed and irrigated systems.
