Design of an Object-oriented Framework for Modelling the Partitioning of Captured Solar Radiation and Evapotranspiration in Intercropping Systems

X-library is a c++ object-oriented framework for modelling the partitioning of captured solar radiation and evapotranspiration in intercropping systems. the design and analysis of the x-library are done to ensure that the soil-plant-atmosphere system is categorised into classes, such as weather, microclimate, intercrop, crop, canopy, leaf, roots, soil, heat, and radiation. meanwhile, x-library implements two kinds of solar radiation models; namely, one-dimensional (1-d), and two-dimensional (2-d) model, where irradiance varies in one dimension (vertical) and in two dimensions (vertical and horizontal), respectively. radiation partitioning is based on weighting criteria so that a crop having the larger leaf area index and extinction coefficient would have greater share of captured radiation. evapotranspiration partitioning is calculated using the shuttleworth-wallace equation. model comparisons with a field experiment showed an overall good agreement between the simulated and measured solar radiation and transpiration values. a graphical user interface front-end for the x-library known as the x-model was also developed, primarily for non-modellers and non-programmers
