We studied several scenarios depending on the parameters: soil and fertilization, irrigation regime and cultivar. We identified the most resistant cultivar to irrigation deficiency as CAR15, which is also the cultivar producing rice with the best WUE. We also modeled these scenarios in AquaCrop to calibrate and validate a model, and especially with the objective to determine the accuracy of the model in stress scenarios. We had some struggles with the modeling as the irrigation records were flawed and we lacked information on some stresses that could impact the rice. Thus, we recommend a better and more rigorous data collection to be able to fit and validate the model properly in the future. ER -
