Biophysical models were developed for biomass accumulation, transpiration and carbon dioxide (CO₂) assimilation of Agave pacifica as functions of air CO₂ concentration, photosynthetic photon flux (PPF) and irrigation interval. Parameter estimation and validation were performed for the Gompertz's equation for biomass accumulation and for the Penman-Monteith equation for transpiration. A new biophysical model for CO₂ assimilation is proposed consisting of four components: stomatal opening and CO₂ fixation; malic acid accumulation; malic acid depletion; and photosynthetic carbon assimilation. The main and interactive effects of air CO₂ concentration, PPF and irrigation interval on biomass accumulation, transpiration and CO₂ assimilation of Agave pacifica were also determined.
