Linking crop agronomic, physiology and modelling studies are important for, assessing the potential and sustainability of different cropping systems in the, Australian Cotton Industry. To ensure that the information collected in these studies, is effectively used and understood by the industry it is important that resources are, dedicated to facilitating the interaction across these disciplines. This is primarily, achieved by ensuring that crop model development is strongly linked to crop, agronomic and physiology studies, as well as activities that apply the model for crop, management and research, and vice versa. Research and ultimate application of the, technology gained in all the fields of study mentioned is often greatly enhanced, when consideration is given to the other components. Sometimes, no component is, effective or directly applicable without some consideration of the other components
