Answer:

A scientific experiment is designed in a way that it includes all the variables to be tested as well as the control group.

In the given question, the student performed the experiment to test if liquid fertilizer is better than dry fertilizer or not?

So, to test this student performed the experiment on a small sample size that is only one plant and lacked a control group which could act as a reference to the experiment. Therefore the additional trial should include a large sample size to remove the error and the control group which provide data to compare.
