Water stress has a significant effect on leaf area expansion rate. To implenment the effects, one needs to modify the model or use manager script to update the model states.

Modify the plant model itself

  1. The process of the effect. Water stress hit the leaf and reduce the rate of expansion. This could be quantified by calculating the ratio of water demand and supply.

  2. Which stage of the crop gets the effect most and first?

  3. Is it a minimum or a multiplication function?

A multiplication function:
