Popis:	This work addresses itself to the problem of deriving feasible computational methods for the determination of temporal and spatial agricultural distribution of productivity for potential application in international food production-allocation modeling. A solution has been sought through the creation of a crop-specific, crop-growth-stage-specific yield model (YIELD). The computer program is a compromise between area-specific regression models and expensive, complex energy and mass transfer models. The intra-seasonal soil moisture and evapotranspiration section of the model has been validated partially in previous publications, whereas the end-of season yield validation portion is briefly discussed in this summary paper of the model.
