Simple model for crop photosynthesis in terms of weather variables and crop character

  • de Jager JM


A theoretical mathematical model for describing crop photosynthetic rate in terms of the weather variables and crop characteristics is proposed. The model utilizes a series of efficiency parameters, each of which reflect the fraction of possible photosynthetic rate permitted by the different weather elements or crop architecture. It is based upon the postulate that at particular growth stages, the average distribution pattern of solar energy through the canopy is a predictable function of crop character. The significance and use of parameters is discussed.
