crete events in the simulation. A small main program calls subroutine GASP, which controls input then initiates the simulation by calling other GASP IV or user-written subroutines_

The vegetative branches start growth at node VB and 10 days after the first vegetative branch starts growth, all have been initiated. VB is calculated by

Plant growth is calculated after STATE calls PLANT, wherein carbohydrate and N balances are performed. A soil-water balance is performed in SOIL Wand soil-nitrogen balance is accomplished in NITRO. Processes necessary for performing the material balances are calculated in various subroutines described below.
