כלאים ז׳Kilayim 7

Mishnah 1א׳

הַמַּבְרִיךְ אֶת הַגֶּפֶן בָּאָרֶץ, אִם אֵין עָפָר עַל גַּבָּהּ שְׁלֹשָׁה טְפָחִים, לֹא יָבִיא זֶרַע עָלֶיהָ, אֲפִלּוּ הִבְרִיכָהּ בִּדְלַעַת אוֹ בְסִילוֹן. הִבְרִיכָהּ בְּסֶלַע, אַף עַל פִּי שֶׁאֵין עָפָר עַל גַּבָּהּ אֶלָּא שָׁלֹשׁ אֶצְבָּעוֹת, מֻתָּר לְהָבִיא זֶרַע עָלֶיהָ. הָאַרְכֻּבָּה שֶׁבַּגֶּפֶן, אֵין מוֹדְדִין לָהּ אֶלָּא מִן הָעִקָּר הַשֵּׁנִי:

If one bends the branch of a vine into the soil to take root, is bent, if there is not a layer of three handbreadths of soil above it, he may not bring [sow] seeds on it. [This is the law] even if he bent it into a [dried out] gourd or an [earthenware] pipe. If he bent it into a rock, even if there is only three fingerbreadths of soil above it, he is permitted to bring [sow] seeds on it. If a vine has been bent in such a manner that the main stem is underground, we only measure [the six handbreadths] from the second root [the place where it rises from the ground and again becomes visible].

Mishnah 2ב׳

הַמַּבְרִיךְ שָׁלֹשׁ גְּפָנִים וְעִקָּרֵיהֶם נִרְאִים, רַבִּי אֱלִיעֶזֶר בַּר צָדוֹק אוֹמֵר, אִם יֵשׁ בֵּינֵיהֶם מֵאַרְבַּע אַמּוֹת וְעַד שְׁמֹנֶה, הֲרֵי אֵלּוּ מִצְטָרְפוֹת. וְאִם לָאו, אֵינָן מִצְטָרְפוֹת. גֶּפֶן שֶׁיָּבְשָׁה, אֲסוּרָה וְאֵינָהּ מְקַדֶּשֶׁת. רַבִּי מֵאִיר אוֹמֵר, אַף צֶמֶר גֶּפֶן אָסוּר וְאֵינוֹ מְקַדֵּשׁ. רַבִּי אֶלְעָזָר בַּר צָדוֹק אוֹמֵר מִשְּׁמוֹ, אַף עַל גַּבֵּי הַגֶּפֶן אָסוּר וְאֵינוֹ מְקַדֵּשׁ:

If one bent [into the ground] and their roots are visible three vines are bent, [and partly covered with mould], should their stems remain visible, Rabbi Eliezer ben Reb Zadok says, If there [is a space] between them of four to eight cubits, they combine [and is considered a vineyard]. If not, they do no combine. A vine that withered, it is forbidden [to sow seeds within six handreadths because of appearance] but is does not render it forbidden . Rabbi Meir says, Cotton is also prohibited [to be planted because it resembles a vine] but does not render [the vineyard] forbidden [as kilayim]. Rabbi Eliezer ben Rabbi Tsadok said in his [Rabbi Meir's] name, Also above the vine [if one bent a vine branch and did not cover it with at least three handbreadths of soil] it is forbidden to sow seeds] but does not render it forbidden [as kilayim].
