Exploration de stratégies d’amélioration de la conduite de l’irrigation de la luzerne (Medicago sativa L.), du bersim (Trifolium Alexandrinum L.) et du maïs ensilage (Zea mays L.) au Tadla – Maroc
The CropSyst model, an operative crop model, is used to explore irrigation scenarios for the main folder crops in Tadla irrigated area in Morocco. The calibration and validation of CropSyst model have been realized previously for alfalfa, silage maize and berseem. The model was run for a 40 year sim...
