Hi,

Could someone assist with how to go about tinkering with genetic
coefficients when calibrating the CERES models (in particular barley and
wheat)? We tried to follow the changes suggested in DSSAT v4.2 but we
are getting extremely low yield values. We have  a very good dataset on
phenology and grain yield from experimental plots over a period of about
3 years. The yield values that we are getting don't make sense at all!!

Thank you,
