Minimum and Maximum
The mishna in Mesechta Peah quoted in the last perek of our mesechta lists the mitzvot which do not have a Torah designated minimum requirement. The mitzvah of tithing terumah does not appear in this list despite the fact that as regards Torah law one can fulfill his obligation by giving the kohen one kernel of grain and it is only by Rabbinic law that he is required to give more.
Rashi explains this omission by pointing out that the amount of tithing established by the Sages is hinted at in certain passages and therefore does not fit in with the other mitzvot for which there are no such scriptural hints.
Tosefot cites the Talmud Yerushalmi's approach to the problem which is to point out that all the mitzvot mentioned in the mishna (peah, bikurim, raion) have neither minimum requirements nor maximum limits. Terumah, on the other hand, has a maximum limit, for if one wishes to give away his entire harvest as terumah, it will not become terumah. This is so because tithing means giving away a portion of your crops but not the entirety.
