In plantings

The prohibition of sowing together diverse seedlings is derived from the biblical verse, "You shall not sow your field with two kinds of seed" (), and which prohibition has been explained to mean planting or sowing two or more diverse vegetable crops within a radius of three- handbreadths, ca. , from one another, where they draw nutrients from each other. As a first resort, however, one is to distance two or more diverse vegetable crops from each other at a remove of six-handbreadths, ca. , even if their foliage were to grow and intermix. Two or more diverse seed-crops must be distanced enough so as to be distinguished from each other as two separate plantings. The prohibition not only applies to sowing together diverse kinds, but also hoeing the ground wherein diverse kinds were sown together, as well as covering them over in top soil, whether by one's foot, or by hand, or by any implement. The same prohibition applies to when they were sown together in a flower pot that was perforated at the bottom. If an entire field was planted with one kind of seedling, but next to that field was another field planted with a diverse kind (whether seedlings or a vegetable crop), the separation distance between the two fields must be 10.2

, the reason for its prohibition being that when seedlings draw nutrients from other seedlings, their properties and natural forms are changed thereby and the sower cancels thereby the fixed design and purpose of the universe. Diverse seed-plantings or vegetables that grew together in violation of the biblical command are permitted to be eaten, although the crop itself must be uprooted. If two diverse grain seeds (e.g. wheat and barley) were inadvertently mixed together, they must be separated before they can be sown. If, however, there were 24 parts more of one grain than the other (ratio of 24 to 1), the lesser grain is considered cancelled by the other, and may still be sown together. If there were not 24 parts more than the mixed grain, the whole must be sorted.


Specific permitted and forbidden species

The first chapter of Mishnah Kil'ayim permits the growing together of certain plants, although the members of each pair belong to two different kinds. An example is certain species of

and Lolium, respectively), but resemble each other in both their seeds and their leaves. Tares are often found growing in wheat fields. Its seeds may germinate several years after being planted so that its growth could not always be prevented. This argument has been used to explain why it was not prohibited to have wheat and tares growing together in the same field. The rabbinic treatise develops the principle that a planter should not only be concerned with the mixing together of different classes of items but also with the appearance of such intermixing, such that if the two kinds are similar in appearance but different genera, this can, at times, be tolerated.

Grafting of trees

The prohibition of grafting of trees is treated on in the

(''Kil'ayim'' 1:4). The prohibition applies to trees growing in the Land of Israel, as well as to trees growing outside the Land of Israel. Among trees, while it is permissible to grow two different kinds of trees in close proximity to each other, it is forbidden for an Israelite (or a gentile working on behalf of an Israelite) to graft the branch (scion) of one tree onto the stump of another tree to produce thereby a hybrid fruit if the trees are not one and the same kind.

Vineyards

A vineyard ( ''kérem'', plural ''karmim'') is defined as at least five vines growing together, two of which are planted alongside an opposite row containing two vines, with the fifth vine tailing the others.Mishnah Kil'ayim 6:1 (Maimonides commentary) A trellis () is where five vines are planted together in a single row. The Chazal described the prohibition of growing diverse kinds in a

However, in places where thorn bushes are used as fodder for camels, and the owner of the vineyard is content to have the thorn bushes grow in his vineyard to that end, the thorn bushes, if maintained, would render the entire vineyard forbidden.

s (''Vigna unguiculata''). By a rabbinic decree, other seed-crops are forbidden to be planted in a vineyard. Had a person transgressed and grew a seed-crop within his vineyard, not only is the produce forbidden to be eaten, but also had he sold the produce, the proceeds accruing from the sale of such produce are also forbidden, and must be burnt, together with the vineyard. The practical bearing of this rabbinic edict is in respect of someone who came along and maliciously sowed Diverse seedlings in his neighbor's vineyard where there is beginning to grow nascent fruit. In such a case, the rabbinic authority has prohibited the seed crop (requiring its burning), but the vineyard and its fruit are still permitted., s.v. ''responsum'' no. 388:2 (Hil.

In animals

The prohibition vis-à-vis animals pertains to their cross-breeding and the prohibition of plowing a field with two different species of animals coupled together, such as with an ox and donkey that are hitched together by a yoke. This prohibition applies also to hitching two kinds of animals together to pull a cart or wagon, and even if it were merely to tie them together behind a wagon. (reprinted from 1922 and 1938 editions of the Hebrew Publishing Co., New York) The prohibition of coupling together diverse kinds of animals applies also to tying together two species of birds. A man and his beast are permitted to plough together. In the classification of animals, the genus ''
