Simulated Responses

The folowing variables are simulated daily:

Crop responses:

  • Canopy temperature (°C)
  • Rooting depth (m)
  • Evapotranspiration (mm)
  • Transpiration (mm)
  • Zadoks growth stage
  • Emerged leaf number (leaf mainstem)
  • Shoot number (shoot m-2)
  • Green area index (m2 m-2)
  • Leaf area index (m2 m-2)
  • Stem length (m)
  • Crop dry matter and nitrogen (kg ha-1)
  • Grain dry matter and nitrogen (kg ha-1)
  • Leaf dry matter and nitrogen (kg ha-1)
  • Laminae dry matter and nitrogen (kg ha-1)
  • Stem dry matter and nitrogen (kg ha-1)
  • Light exposed sheath dry matter and nitrogen (kg ha-1)
  • Specific leaf dry mass and nitrogen (g m-2)
  • Single grain dry matter, nitrogen, and starch (kg ha-1)
  • Quantity of albumin-globulin, amphiphil, gliadin, and glutenin proteins per grain (mg N grain-1)
  • Post-anthesis crop nitrogen uptake (g N ha-1)

Leaf laminae, light exposed sheath and true stem surface area, dry matter and nitrogen mass per unit ground area and per unit of leaf area (specific mass) are modeled at the phytometers level and are exported in standard output files for each phytomer and for the whole canopy.

Grain number per unit ground area, final leaf number, anthesis leaf area index and green area index, anthesis and ripeness maturity crop and grain dry matter and nitrogen mass per unit ground area, post-anthesis crop nitrogen uptake, ripeness maturity single grain dry matter, nirogen, and starch mass per unit ground area, grain protein and starch concentration, proportion of albumin-globulin, amphiphil, gliadin, and glutenins, gliadin-to-glutein ratio, and dry matter and nitrogen harvest index are also calculated in standard output files.

Soil responses:

  • Top soil temperature (°C)
  • Soil water drainage (mm)
  • Available water in soil profil (mm)
  • Water deficit in soil profil (mm)
  • Available water in root zone (mm)
  • Water deficit in root zone (mm)
  • Fraction of transpirable soil water (dimensionless)
  • Soil nitrogen leaching (kg N ha-1)
  • Soil nitrogen mineralisation (kg N ha-1)
  • Denitrification (kg N ha-1)
  • Available mineral nitrogen in soil profil (kg N ha-1)
  • Total mineral nitrogen in soil profil (kg N ha-1)
  • Available mineral nitrogen in root zone (kg N ha-1)
  • Total mineral nitrogen in root zone (kg N ha-1)

soil water and nitrogen content are simulated daily through the soil profil for 5-mm thick layers.

Ripeness maturity total available soil nitrogen, nitrogen leaching, water drainage, cumulative nitrogen mineralisation and denitrification in soil profil, plant available water content in soil profil are also calculated in standard output files.

Crop stress factors:

  • Dry mass drought factor (dimensionless)
  • Ear growth drought factor (dimensionless)
  • Leaf expansion drought factor (dimensionless)
  • Senescence drought factor (dimensionless)
  • Transpiration drought factor (dimensionless)
  • Nitrogen nutrition index (dimensionless)
