Nedarim 59 - December 23, 29 Kislev - a podcast by Michelle Cohen Farber

Rami bar Hama raises a question from our Mishna against those who hold that the growths nullify the original part that was planted. However, our Mishna is explained as a unique case as a neder can be undone, and therefore it is considered an item that will be permitted and rules of nullification do not apply. However, truma also can be undone and it is subject to laws of nullification. After two unsuccessful attempts to reexplain a Mishna in Trumot to be a case where the truma can’t be undone, in the end, the Gemara distinguishes between truma and vows as vows should be undone and that is not true by truma. Raba quotes Rabbi Yochanan also stating that the growths nullify the original. Rav Chisda questioned this but Raba proves Rabbi Yochanan’s opinion from a Mishna. However, Rav Chisda explained the Mishna differently in a way that would prove his point. But Raba was still able to support his claim by distinguishing between the cases.
