Abstract

Crop models are derived from quantitative models that comprise empirical models and mechanistic models. Four situations of crop production were used in crop modeling. 1) potential crop production, 2)water-limited crop production, 3) nitrogen-limited crop production and 4) other plant nutrient-limited crop production. Crop modeling can be used to predict the limiting factors of rubber trees. It was found that the estimated rubber yield is highly correlated with the actual yield. Moreover, this method may be used to assist in the rubber decision-making systems and rubber simulation model. Therefore, the crop model can be applied to predict the actual yield and enhance rubber production potential.
