Implémentation et évaluation du modèle de culture de pois (Pisum sativum L.) AFISOL sous la plate-forme logicielle RECORD

subject

description

The pea crop is very beneficial since it fixes atmospheric nitrogen and protein source for animals as well as humans. To overcome the deficiency of performance which it suffers, research aims to develop new varieties tolerant to stress (biotic and abiotic). A numerical model of the functioning of the Pea "AFISOL" was designed in Excel. However, the model in EXCEL does not help the use of the model and its accessibility to a large number of people. The objective of this internship is: - To implement the model AFISOL in the platform modeling RECORD developed by INRA. This platform uses the VLE software based on C + + language. - To make a study of sensitivity analysis showing the effect of the parameters on the output variables of the model. The AFISOL model was designed in GVLE with several boxes. It is composed of an atomic model (climate) and three coupled models (soil, plant, and stress). They are interconnected by coupling variables which are represented by arrows and have input and output ports. The atomic model was exported from METEO model has been modified for use. The Sol coupled model was modified after being exported AZODYN-COLZA model. The coupled model “Plant” was designed entirely in GVLE. Although it has benefits including the layout and design of the model, some difficulties have been encountered in the implementation of the model AFISOL in RECORD and could be improved in the future. The simulation results of some output variables of the two atomic models implemented were consistent with those observed in EXCEL. The sensitivity analysis has begun, on the output variable date of emergence (DateLe).
