Determination of Sensitivity of the Winter Wheat Crop to Meteorological Factors by DAISY Model Nilcan Altınbaş1*, Mahir Aydın1, İrem Özmen1, Barış Çaldağ1, Levent Şaylan1 1 Istanbul Technical University, Faculty of Aeronautics and Astronautics, Department of Meteorological Engineering, Istanbul, TURKEY [*]akatas@itu.edu.tr [*] Corresponding author: akatas@itu.edu.tr [*] ABSTRACT Climate change or climate variability has always pose a risk for sustainable agricultural production. Changes in meteorological factors may have different effects on different phenological stages of plants. For this reason, not only the quantitative change of meteorological factors but also the temporal variation of these factors’ effects of plant growth and yield should be investigated. In this study, DAISY crop growth simulation model was used to analyze the sensitivity of winter wheat plant to meteorological factors during flowering period. In this context, the effect of changes in temperature, rainfall and total solar radiation during the flowering period has been examined. Key words:Climate change, Crop growth, Crop yield [*] Corresponding author: akatas@itu.edu.tr
