The wolf and dog, village dog and fox, goats and gazelles, ibex and ewes, horse and mule, mule and donkey, donkey and wild ass — even though they are similar to one another, they are kilayim with one another.

One may not bring [together] a tree with a tree, nor greens with greens, nor a tree with greens, nor greens with a tree. R’ Yehudah permits greens with a tree.

One may not plant greens inside the stump of a sycamore, nor may one graft rue to cassia, as this is ‘‘greens with a tree.’’

[If] someone stores turnips or radishes under a grapevine — if some of their leaves are exposed, he need not be concerned about kilayim, nor about sheviis, nor about tithes, and they may be taken on the Sabbath. [If] someone sows a wheat grain and a barley grain together, this is kilayim. R’ Yehudah says: It is not kilayim until there are two wheat grains and one barley grain, or a wheat grain and two barley grains, or a wheat grain, a barley grain and a spelt grain.
