Characterization of the main climatic stress encountered by spring peas grown on deep soils (maximum water availability = 150 mm) without irrigation, in Eure-et-Loir (one department with the highest areas in the 90s) from 1992 until 2015: drought stress (cumulated difference between Maximal Evapotranspiration (MET) and Real Evapotranspiration (ETR) between beginning of flowering (BF) and final stage in seed abortion (FSSA)), and thermal stress (cumulated maximal temperatures exceeding 25 °C between BF and FSSA).
