No, you can't omit "of". The set phrase is "a/the concept of" followed by the description of the concept.
If you omit it, you are left with "It includes the concept daily planning ..." which I'm sure you know is not correct. It is used three times in the original sentence because it includes three concepts. The writer could have written "the concept of" three times but it's not necessary.
It also includes the concept of A, of B and of C = It also includes the concept of A, the concept of B and the concept of C.
