From what I know and understand, it depends on what is you main point of interest. As far as APSIM is considered, it is a relatively easy and comprehensive modeling for yield simulation mainly for the crop and soil management parameters, such as NPK, Fertilizers, Sowing dates etc. However, APSIM doesn't account for the pest and disease infestation. So, perhaps, you can decide on what your research priority or objective is.

hi,

APSIM has many parameters country wise but in case india there is not any ,can you please suggest from (infocrop model ceres-wheat,rice,DSSAT?

Jaya is right.CERES is quite known to all.

sir tell me about ceres model ?is it free ?which parameters used in this model to get agriculture productivity?can we do forecast from it too??

Thank you

As per Indian condition INFOCROP is good

APSIM could be an option
