Derek:

CERES and the other models write LAI to a file called GROWTH.OUT.  Your
last question gives the impression that you have not tried to run any of
the example data sets that are distributed with DSSAT.  The equation that
describes LAI for the CERES models can be found in a chapter written by
Ritchie, Singh, Godwin and Bowen entitlted "Cereal growth, development and
yield."  This chapter is published in the book Understanding Options for
Agricultural Production.
