Research interests: Irrigation of agricultural and horticultural crops: yield and quality responses under field conditions. Development of irrigation DSS “Vandregnskab” @ www.planteinfo for Danish agriculture. Plant water relations: water content/potential/capacity, uptake and transport. Plant responses to stress at the physiological, biochemical and genomic level. Stomatal regulation and its influence on evapotranspiration.
Involvement in research projects: SAFIR (Safe and High Quality Food Production using Low Quality Waters and Improved Irrigation Systems and Management) is a large EU-STREP with 17 partner from EU and China that we coordinate at DIAS. “Irrigation in a Holistic Resource Perspective” is a Danish Ministry of Agriculture project aiming to improve decision support to farmers and optimize the water use efficiency of traditional farming and irrigation systems. “The physiological basis for improving water use efficiency in crop plants under partial root zone drying (PRD) irrigation strategy” is a postdoc project granted by the Agricultural and Veterinary Research Council, where we (KVL and DIAS) investigate hydraulic and chemical signals in potato plants as a response to (spatially confined) soil drying. Effects on stomatal conductance, water use efficiency and yield and quality parameters are measured.
Advisor for PhD students: Seyed Hamid Ahmadi: Study of soil water dynamics under partial root drying (PRD) irrigation for developing water saving irrigation strategies. Ali Shahnazari: Irrigation strategies and water use efficiency under arid conditions.
