Louis,
Thanks again!
Hope that I could still solicit suggestions from you whenever other concerns about simulation arise.
Regards
Arnold

Sorry Arnold, had finger trouble. I would not like to hazard a guess, but if
you have a date where you knew the soil profile was wet, start there.

Louis,
Its Arnold not Arnolg, anyway, tahks for the information and idea. If you
would not mind what if I was just running 1 season simulation or forecast,
what do you recommend the start of simlulation date with reference to
planting date?
Thanks and regards,
Arnold

Arnolg,
Of course your starting date will have a lot to do with your yield because
this has everything to do with the amount of water in the soil when
planting. I have found that only if I start two years before planting date
can I have confidence in the modeled staring water content. So, whenever I
make a 30-year run, I run 32 years of simulation and throw away the first
two years. If you have a good handle on moisture content when starting
simulation, this would help.

Dear Colleagues,
Greetings!
Recently I run a simulation in CERES-Maize and I found out that whenever I
change the starting date for simulation,there were variation in the yield
output data. Can anybody explain why is this so? and I just want to ask if
there's any standard date to start simulation in relation to the planting
date?
Thank you and best regards,
Arnold R. Salvacion
