New modelling solutions to simulate hazelnut

The importance of hazelnut (Corylus avellana L.) for the food industry is rising. The sensitivity of this species to water stress and high temperatures (especially during fruit ripening) is well documented, which poses the need of using process-based models to support the analysis of the impact of environmental and management conditions on growth and production. For that purpose, Bregaglio et al. (2016) developed two approaches (Farquhar-based and radiation-use efficiency based) to model hazelnut development and growth, and evaluated them in Northern Italy conditions (including extreme conditions of aridity). The satisfactory agreement obtained with both solutions to reproduce inter-annual fluctuations of yield is encouraging for their application for research purposes and management support. This study also opens up to the implementation of dedicated modelling solutions within operational yield forecasting systems.
