Dear RG scholars, GREETINGS!!!
- I'm relatively new to CROP MODELING and Simulation
- As you all know, modeling is so interesting but as wide as an ocean.
- Modeling includes many challenging topics such as model calibration, parameter estimation, reliability assessment, data collection design, and a lot more.
I'm doing my research on "Model simulation of maize growth and yield using DSSAT-CERES-maize model v.4.7.".
No model was done before for my location.
I'd two-year experiments using 3 maize varieties and 5 nitrogen rates for a new
(same location but different years).
- 1st year for model calibration
- 2nd year for model validation
N.B.
- My maize is rain-fed maize
- I've 30 years of climate data (RF, Tmax & Tmin)
- I've soil and plant lab analysis results
What parameters, mandatory data, and what max and min values should I have?
What vital steps should I never forget?
What yield components of maize should I focus on?
Your experience, please? And any relevant reference you think is good for me!!!
STAY BLESSED!!!

High Alem,
Interesting to start discussions on DSAT!
I recommend you first to read the manual. What type of soil sample ( profile or surface)? It is the profile data you need. Crop data is highly important and there are variety specific parameters. You have to know that! I knew for the varieties BH540 and BH660 for example in Ethiopia. I hope you know Dr Kinde from CIMMYT Ethiopia, he will help you a lot about DSAT as he is an expert on it.
Dear Tadele Amare Kassie, big greetings!!!
Thank you so much for your valuable insights and nice information.
Please share with me if you have any helpful sources on BH-546, BH-661, and M-2 maize varieties.
STAY BLESSED!!!

Dear Dr. Shanmugam Vijayakumar, thank you so much for your helpful hint.
You cleared my foggy mirror!!
STAY BLESSED!!!
