To recreate the surface air pressure of Mars, this experiment should be taking place at an altitude roughly five times the height of Everest or a similarly evacuated chamber. Mars is harsh. (Edit: i.e. yes, all agriculture will likely need to take place under the sort of structures you see on the cover of sci-fi novels from 60s and 70s).

Earth atmosphere normal pressure is 1 atm. Essentially, being on the surface of Mars is being in space. And what about the radiation? Mars has no magnetic field like Earth has. So the Solar Wind has free play on the surface.
