No types of zeraim may be planted in a patch, but all types of greens may be planted in a patch. Mustard and smooth beans are types of zeraim. Large beans are types of greens. A border which was a handbreadth high and was reduced is acceptable, since it was acceptable at the start. If a furrow or water channel is one handbreadth deep, one may plant inside it three species, one over here and one over here and one in the middle.

[If] a rosh tor of greens entered into a field of a different [type of] greens, this is permitted since it appears like the end of his field. If his field was planted with greens, and he wants to plant inside it a row of a different [type of] greens — R’ Yishmael says: [Not] until the furrow reaches from one end of the field to the other. R’ Akiva says: A length of six handbreadths and a width equal to its fullness. R’ Yehudah says: A width the full width of a foot.

[If] someone plants two rows of melons, two rows of gourds, [and] two rows of Egyptian bean — [this is] permitted. A row of melons, a row of gourds, [and] a row of Egyptian bean — [this is] forbidden. A row of melons, a row of gourds, a row of Egyptian bean, and a row of melons — R’ Eliezer permits, but the Sages forbid.

A person may plant a melon and a gourd in the same hole, provided that this one leans to this side and this one leans to this side [and the hair of this leans to here and the hair of this leans to here, for all that the Rabbis prohibited was decreed only because of suspicious appearance].

[If] his field was planted with onions, and he desired to plant inside it rows of gourds — Rabbi Yishmael says: He uproots two rows and plants one row and leaves standing onions in place of two rows and uproots two rows and plants one row. Rabbi Akiva says: He uproots two rows and plants two rows and leaves standing onions in place of two rows and uproots two rows and plants two rows. But the Sages say: If there are not twelve cubits between one row [of gourds] and the next, he may not retain the plants in the middle.

Gourd in greens is like greens. But in grain, we give it a beis rova. [If] his field was planted with grain, and he wished to plant inside it a row of gourds, we give it for its work six handbreadths. If it grew large, he must uproot in front of it. R’ Yose says: We give it for its work four cubits. They said to him: Do you treat this more stringently than the grapevine? He said to them: We find that this is stricter than the grapevine, because for a single grapevine we give for its work six handbreadths, while for a single gourd [plant] we give a beis rova. R’ Meir says in the name of R’ Yishmael: If there are three gourd plants per beis se’ah, he may not bring [other] seed into the beis se’ah. R’ Yose ben HaChotef Efrosi said in the name of R’ Yishmael: [If] there are three gourd plants per beis kor, he may not bring [other] seed into the beis kor.

The clearing of a vineyard — Beis Shammai say: twenty-four cubits. But Beis Hillel say: sixteen cubits. The perimeter of a vineyard — Beis Shammai say: sixteen cubits. But Beis Hillel say: twelve cubits. And what is the clearing of a vineyard? A vineyard which has been destroyed in its middle. If there are not sixteen cubits there, he may not bring [other] seed there. [If] there were sixteen cubits there, we give it its work area, and he may plant the rest.

What is the perimeter of the vineyard? [The area] between the vineyard and the wall. If there are not twelve cubits there, he may not bring seed there. [If] there were twelve cubits there, we give it its work area, and he may plant the remainder.

R’ Yehudah says: This is none other than the wall of a vineyard. But what is the perimeter of a vineyard? Between two vineyards. What is a wall? [That] which is ten handbreadths high. And a ditch [is that] which is ten deep and four wide.

A partition of sticks — if there are not three handbreadths between one stick and the next, enough room for a goat to enter, then this is a partition. A wall that has been broken — up to ten cubits, this is like an opening; more than this, it is forbidden [to plant] opposite the breach. [If] many breaches have been made in it — if the standing [part] is greater than the breached, it is permitted. But if the breached [part] is greater than the standing [part], opposite the breach it is forbidden.

[If] someone plants a row of five grapevines — Beis Shammai say: [It is] a vineyard. But Beis Hillel say: It is not a vineyard until there are two rows there. Therefore, [if] someone plants [within] the four cubits of a vineyard — Beis Shammai say: He has condemned one row. But Beis Hillel say: He has condemned two rows.

[If] someone plants two opposite two, and one protruding like a tail, this is a vineyard. Two opposite two and one in between, or two opposite two and one in the middle, is not a vineyard until there are two opposite two and one protruding like a tail.

[If] someone plants one row within his own property, and there is one row within his neighbor’s property, and there is a private road or a public road in the middle, or a wall which is lower than ten handbreadths, then these [rows] combine. [If the wall is] higher than ten handbreadths, [the rows] do not combine. R’ Yehudah says: If he intertwined them above, then they combine.

[If] someone plants two rows [of vines] — if there are not eight cubits between them, he may not bring [foreign] seed there. [If] there were three [rows] — if there are not sixteen cubits between one row and the next, he may not bring [foreign] seed there. R’ Eliezer ben Yaakov says in the name of Chanina ben Chachinai: Even if the middle [row] is destroyed, and there are not sixteen cubits between one row and the next, he may not bring seed there, even though had they been planted [thus] to begin with, it would have been permitted with eight cubits.
