Mandatory skills in plant biology, plant physiology and genetics acquired during the Bachelor of bioengineer or equivalent
General principles of ecophysiology of major crops
Biomass production and resources capture
Passage from the isolated plant to the plant population
Plant growth and development, yield components
Morphology, phenology, physiological factors, biotic and abiotic stresses
Application to several temperate, tropical and ubiquitous crops
a. Contribution of the activity with regards to the referential of leaning outcomes
Control a pool of scientific knowledge in the field of plant production (M1.1, M1.2, M2.2)
Control a pool of knowledge in the fied of bioengineering through a quantitative approach, facing a complex problem of agronomy at the scales of the plant and the field (M2.4)
Apply a rigorous, innovative and systematic scientific approach in order to deepen a research problem in the field of crop production (M3.3, M3.4)
b . Specific formulation for this activity AA program (maximum 10)
At the end of this activity, the student will be able to :
· explain the life cycle of a crop and identify the activity periods of each process operating in biomass formation ;
· express the principles of yield formation ;
· connect processes between themselves ;
· identify the key phenological stages studied during the lectures ;
· compare the adequacy of different crops to defined pedo-climatic scenarii ;
· predict the biomass evolution in the field during the vegetative phase ;
· examine the production differences under a range of physiological and pedo-climatic constraints ;
· formulate a given situation encountered in the field (e.g. a given season) in a quantitative way with the help of concepts studied during the lectures, interpret it and propose an analytical strategy in order to vallidate this interpretation.
