Maaseros 4:5-6

Maasros 4:5

If one removes barley hulls, he may do so one at a time and eat them. If he removed the hulls and collected the barley in his hand, it must be tithed. If a person rubs parched wheat to remove the chaff, he may sift the chaff in his hand and eat the grain. If he sifted the chaff and put the grain in his lap, it must be tithed. If a person planted coriander to get seed, the plant need not be tithed; if he planted it for the plant, then both the plant and its seed must be tithed. Rabbi Eliezer says that in the case of dill, the plant, its seed, and also the thin stalks must be tithed. The Sages say that field pepper and arugula are the only plants where both the plant and its seed must be tithed.

Maasros 4:6

Rabbi Shimon Ben Gamliel says that the buds of fenugreek, mustard and white beans must be tithed. Rabbi Eliezer says that caper stalks, berries and flowers all must be tithed; Rabbi Akiva says that only the berries must be tithed because that's the fruit.
