Learning outcomes
The aim of this teaching is to provide the knowledge on: 1) different productive management system (integrated, organic, etc.) 2) orchard ecosystem biodiversity and strategies to improve it, 3) fruit tree vegetative and reproductive cycles, and techniques for a sustainable management, 4) fruit biochemical composition, development and physiology, 5) economic and environmental sustainable fruit tree management. This knowledge will allow the student to select and employ the most appropriate techniques to obtain a high quality product with the lowest environmental impact

Slide of the classes are available on the teacher website of the University of Bologna. However the class presentations are not sufficient to have an adequate preparation. On the other hand the teacher is available to provide International students with appropriate materialsTeaching methods
Teaching is divided in 2 parts: lessons in classroom (60%) and practical activities (40%) in field and laboratories. Classes include digital presentations with figures and photos to complete book information. Students are asked to participate to the class actively by explaining their point of view on some topics on environment and economic sustainability, management etc., and commenting professor issues. Regularly the level of understanding will be evaluated by going over the previous topics. Particular attention will be made on the practical activities, taking advantage from the experimenatl farm of Cadriano (near Bologna). Students will be encouraged to participate practically to the field and lab demonstrations.
From this point of view student class attendance is encouraged as the principal part of the educational pathway
Laboratory activities are also scheduled to show the students the most important index to evaluate fruit ripening (refractometer, penetrometer, starch test, colorimeter, DAmeter, NIRs , ecc.).
Assessment methods
The exam consists of a 40 minuts final exam, which aims to quantify the skillness and expected expertise through an oral examintion with no possibility to use books, notes, or any other supports. The oral examination includes an interview on, at least, 3 topics discussed in class, with the aim to evaluate the student learning level, ability of critical analysis, capability to link the different topics taught in class, and apply the knowledge to the different environmental conditions.
To pass the exam with the minimum grade (18/30) student should show a sufficient knowledge of the 3 topics, or a good knowledge of 2 out of 3 questions. The maximum grade (30/30) will be obtained by showing an excellent knowledge of all the topic discussed.
Teaching tools
The class will be run with the help of digital slides (power point or similar). The slides will be made of few words with large size of the letter using a clear font (i.e. 'arial'), to allow dyslexic student to follow the class. Upon agreement, during the reception time, the teacher is available to give exrtra explanation to student with learning difficulties.
