Hi,
 
I am working on amplifying DSSAT with a few new crop options, such as
the tropical grass Brachiaria decumbens and a some green-manure legumes
(mucuna, cowpea, canavalia). For this, I have to make modifications to
the species file (*.spe), the cultivar file (*.cul) and the ecotype file
(*.eco). Only the *.cul parameters are explained in the DSSAT manual
(vol. 2, p.197). The *.spe and *.eco parameters seem not to be explained
anywhere, which does not make it easy to figure out what the parameters
mean and how to modify them.
 
Does anyone have a parameter listing -- complete or incomplete -- with
explanation of what each of them means or suggestions on how to estimate
them?
 
Thanks,
