Dear Hiroshi,

Yes, DSSAT uses its maximum grain filling rate during what it calls the
effective grain filling period. But I am not sure how  G3 is normally
computed; perhaps persons with more Ceres-Maize experience can tell. If
processing of experimental data ignores small weight increments before and
after the linear grain filling phase, and if those increments are allocated
to the linear phase, maximum grain filling rate will be slightly
over-estimated. This is not noticed if this maximum grain filling rate is
used accordingly, as of course Ceres-Maize itself does.

Regards,

Anne Elings
