Hi Steve,

Which version of DSSAT are you using? In DSSAT4.0, you can find the
parameters P1, P2, .... Adjust them, you can extend the growth period.


In the .ECO file,
! P1      Duration of phase end juvenile to double ridges (PVTU)
! P2      Duration of phase double ridges to end leaf growth (Leaf units or
TU)
! P3      Duration of phase end leaf growth to end spike growth (LU or TU)
! P4      Duration of phase end spike growth to end grain fill lag (TU)

Good Luck.

Luo Yi
