Any day field farming is a better choice for experiments, particularly if you want to go to scale.

Thank you

Field experiments are better.

That depends. If you want to study a pure biological responses of crops to treatments, it is good to start with the pot experiment. When you will find an interesting response, then expand it into the field operations.

The pot culture is suitable for initial trial. But field culture is must require for final trial.

Thank you

first do experiment in pod then expand into field
