751-3700-00LPlant Ecophysiology Information 2 credits2VM. Gharun, M. Lehmann, A. Walter
AbstractThe general theme of this course is the effect of environmental factors (such as light, temperature, relative humidity, CO2 concentrations, etc.) on plant physiology: water uptake and transport, transpiration, CO2 gas exchange of plants (photosynthesis, respiration), growth and C allocation, yield and production, stress physiology. Lab and field measurements are is included.
ObjectiveThe students will understand the impact of environmental factors on plant physiology and will learn the theoretical basis and terminology of plant ecophysiology that is necessary to analyze yield potentials in agriculture. The students will learn about classical and latest studies in plant ecophysiology and will have hands-on experiences with equipment used in plant ecophysiology.
ContentDas Ziel vieler landwirtschaftlicher Managemententscheidungen, d. h., das Erhöhen der Produktivität und des Ertrages, basiert häufig auf Reaktionen der Pflanzen auf Umweltfaktoren, z. B. Nährstoff- und Wasserangebot, Licht, etc. Daher werden in diesem Kurs der Einfluss von Umweltfaktoren auf die pflanzliche Physiologie behandelt, z. B. auf den Gaswechsel von Pflanzen (Photosynthese, Atmung, Transpiration), auf die Nährstoff- und Wasseraufnahme und den -Transport in Pflanzen, auf das Wachstum, den Ertrag und die C-Allokation, auf die Produktion und Qualität der produzierten Biomasse. Anhand der wichtigsten Pflanzenarten in Schweizer Graslandökosystemen werden diese theoretischen Kenntnisse vertieft und Aspekte der Bewirtschaftung (Schnitt, Düngung, etc.) angesprochen.
Lecture notesHandouts stehen online.

Prerequisites / NoticeDieser Kurs basiert auf Grundlagen der Pflanzenbestimmung und der Pflanzenphysiologie. Er ist Basis für die Veranstaltungen „Pflanzenbau, Teil Futterbau“ und „Graslandsysteme“.
751-4104-00LAlternative Crops2 credits2VA. Walter, K. Berger Büter
AbstractFew crops dominate the crop rotations worldwide. Following the goal of an increased agricultural biodiversity, species such as buckwheat but also medicinal plants might become more important in future. The biology, physiology, stress tolerance and central aspects of the value-added chain of the above-mentioned and of other alternative crops will be depicted.
ObjectiveDuring this course, students learn to assess the potential of different minor or alternative crops compared to the dominant major crops based on their biological and agronomical features. Each student will assess and present a specific alternative crop of his or her choice based on information from scientific articles and Wikipedia. Wikipedia-entries will be generated.

AbstractAgriculture needs to become more sustainable via innovative approaches. This course allows students to explore in group work, how this could be realized. There are short impulse talks on 'Smart Farming' given by experts on technology and entrepreneurship. Most importantly, students elaborate the first steps to create a startup company in this field.
ObjectiveDuring the course, the students generate their own ideas on 'Smart Farming'. They explore, which technologies provide possibilities for a more sustainable agriculture. They realize trade-offs between economic and technological possibilities.
