QB-Maize (Quick Basic) is a simulation model similar to other crop growth
models that model plant growth processes. With QB-Maize, an attempt
has been made to simplify plant growth and development processes.
The model was developed by Tom Sinclair at the ARS/University of Florida.
The model has several components:
- input subroutines,
- leaf growth,
- carbon budget,
- seed growth, and
- water budget subroutines.
The model requires meteorological inputs consisting of daily maximum
and minimum temperatures, precipitation and solar radiation.
Agronomic input includes planting date and population data.
Model output includes leaf area index (LAI), evapotranspiration, dry
matter and grain mass. The model uses a daily time step. It
models plants at the plot scale. It is written in QB-Basic and
can be run on any IBM compatible PC.
This model can be used for comparing its output against other crop growth models
(such as CERES). It can also be linked to GCMs or any weather generator
(e.g. WGEN) to examine the relationship between crop production

Global change implications:This model can be used for global changeresearch by comparing its output against other crop growth models(such as CERES). It can also be linked to GCMs or any weather generator(e.g. WGEN) to examine the relationship between crop productionand climate.
