A systematic approach for re-assembly of crop models: An example to simulate pea growth from wheat growth

► The process of model building using modular frameworks asks for interdisciplinary work. ► Use of the systematic approach for model re-assembling promotes transparent and reproducible models. ► Crop modelling framework facilitates models' changes at three levels: parameters, equations, and structure. ► Use of the approach helps to control model complexity while simulating emergent properties at crop level.
