One who makes a neder prohibiting dagan is forbidden dry Egyptian beans; [these are] the words of R' Meir. The Sages, however, say: He is forbidden only the five varieties. R' Meir says: One who makes a neder prohibiting tevuah is forbidden only the five grains. However, one who makes a neder from dagan is forbidden all, but he is permitted fruit of the tree, and greens.
