Chabad.org — English translation + Rashi
Torah Temimah cites Yerushalmi Maasros 5:2.
English: “And you shall gather its produce.” It was taught: Rabbi Yonasan son of Rabbi Yosei says: From where do we know that produce which reached one-third of its growth before Rosh Hashanah of the Shemittah year may be gathered in during the Shemittah year? The verse says “and you shall gather its produce” — in the seventh year.
Classical derasha (Yerushalmi) — from the wording of the gathering clause.
Produce that reached one-third of its growth before Rosh Hashanah of the Shemittah year may be gathered during the Shemittah year itself.
