Dear DSSAT users,
I am conducting a tomato experiment and i have the following issue:

Keeping everything else constant (i.e. irrigation dates, fertilizer applications etc.) and only changing the cultivars between the 3 available options the Harvested yield is the same among different cultivars (i.e. 1991 yield for BHN is equal to 1991 harvested yield for Sunny S-D and to 1991 yield for Fit S-D, this happens for all the years and planting dates of my model). My expectation was to have different yields for the different cultivars.

I was wondering if anyone has a possible explanation why this happens.
Thank you very much,
Have a great weekend

P.S. i am conducting a seasonal experiment
