תלמוד על בבא בתרא 9:7

They brought before him two radishes from between New Year’s Day and the Great Fast⁸⁰Yom Kippur, the Tenth of Tishre. The radishes probably were offered for sale on Yom Kippur Eve.. It was the year after a Sabbatical, and they were a full camel’s load. He said to them, are they not forbidden as aftergrowth⁸¹One may not use any plant grown in the Sabbatical year for commercial purposes (and one may not use any produce if nothing of the same kind is left on the fields for wildlife.) Hence, the free growth of the Sabbatical is forbidden in commercial transactions even after the end of the Sabbatical year.? He said to him, they were sown at the end of New Year’s Day. At that moment did Rebbi permit to buy vegetables immediately after the end of the Sabbatical year.
