Simulation of pineapple growth, development, and yieldJ. Zhang,D.P. BartholomewActa Horticulturae, 1993 View paper
The ALOHA (Assessment of Local Options for Hawaii Agriculture) pineapple model was developed based on the CERES-maize model structure but has diverged considerably over time. The model is a physiologically-based, process-oriented crop model that is incremented on a daily time step. It simulates crop response to environmental factors and management practices. Three growth phases are modeled, the vegetative phase from transplant to forcing (application of a growth regulator), from forcing to opening of the first flower, and from time of flowering to harvest. User-specified applications of growth regulators are used to force flowering, a management practice used by all commercial growers of pineapple. The ALOHA model was added to DSSAT v4.7 in 2017.
Some case studies
The model was calibrated and tested using data sets from several important producing countries with different environments (southeastern Queensland, Australia, Cote d’Ivoire, Hawaii, USA, and Thailand).
