UKMaize::UKMaize ( TTypesOfVegetation  a_tov, TTypesOfCrops  a_toc, Landscape *  a_L  )

inline

When we start it off, the first possible date for a farm operation is 1st September This information is used by other crops when they decide how much post processing of the management is allowed after harvest before the next crop starts.

                                                                           : Crop(a_tov, a_toc, a_L)

Do()

bool UKMaize::Do ( Farm *  a_farm, LE *  a_field, FarmEvent *  a_ev  )

virtual

The one and only method for a crop management plan. All farm actions go through here.

Called every time something is done to the crop by the farmer in the first instance it is always called with m_ev->todo set to start, but susequently will be called whenever the farmer wants to carry out a new operation.
This method details all the management and relationships between operations necessary to grow and ALMaSS crop - in this case conventional maize.

Reimplemented from Crop.
