Interpretive Summary: Crop management and simulation models require understanding and predicting the phenological development of crops. However, the complete developmental sequence of the shoot apex for essentially all crops has not been summarized, which presents many difficulties when researchers and practitioners work with unfamiliar crops. This paper presents work on a prototype computer program that synthesizes and quantifies the entire developmental sequence of many crops, making this information readily available to users with limited knowledge of phenology or the crop of interest. The Java interface allows for easy interaction with the underlying Fortran program that calculates the growth stages and the information system explaining specific details of crop phenology. To date, the prototype simulates winter and spring wheat and barley, corn, proso millet, hay millet, and sorghum, and the developmental sequences and preliminary validation results are presented.
