Pe'ah should not be left in one field for another field.
What is implied? If [a person] owned two fields, he should not harvest one entirely and leave the amount of pe'ah appropriate for both in the second field. [This is derived from Leviticus 23:22:] "Do not completely remove [the grain in] the corners of your field." [Implied is] that one should leave in each field the pe'ah that is appropriate for it. If one left [pe'ah] from one field for another, it is not pe'ah.

Although one's entire field was sowed with one crop, if there was a stream - even if did not flow1 - or an irrigation ditch - provided water flowed through it and it was established2 - in the midst of the field that would prevent one from harvesting both sides at the same time,3 it is considered as two fields and one should give pe'ah on each side for the portion there.

Similarly, a path belonging to a private individual which is four cubits wide or a public thoroughfare which is sixteen cubits wide separates [between one field and another]. [Different rules apply regarding] a private path that is less than four cubits wide or a public path that is less than sixteen cubits wide.4 If it is permanent, i.e., it is maintained in the summer and in the rainy season, it is considered as a separation. If it is not permanent in the rainy season, it is not considered as a separation and [the entire area] is considered as one field.

There are other factors which constitute a separation into two fields:
a) land that was uncultivated, that was neither sown, nor plowed;
b) land left fallow, that was plowed, but not sown;
c) crops were interrupted with another crop, e.g., there was wheat on either side and barley in the middle;5
d) one harvested in the middle of his field before the grain reached a third of its maturity and plowed the portion which he harvested.6
[The above applies] provided the width of each of the above is three rows of plowing. [This is] less7 than the area necessary to sow a quarter [of a kav].8
When does the above apply? With regard to a small field that is 50 cubits by two cubits or less. If it is larger than this uncultivated or fallow land does not cause it to be divided in two unless it was as wide as the area necessary to sow a quarter of a kav.9 [In this instance,] even the smallest amount of another crop creates a separation.10

If locusts consumed [a field] in its midst or ants destroyed it, should one plow the portion that was consumed,11 it is considered to be a separation.

Mishneh Torah (Moznaim)
Featuring a modern English translation and a commentary that presents a digest of the centuries of Torah scholarship which have been devoted to the study of the Mishneh Torah by Maimonides.
[The following law applies when one] sows [crops] on a mountain [slope] that is not level, but instead has knolls and hollows. Even though he cannot plow it all at once and sow it all at once, but instead must plow the knolls by themselves and the hollows by themselves, it is considered as a single field. He should leave one portion of pe'ah at the end of the mountain for the entire mountain.12

[The following laws apply when one sows crops on] terraced land. [When each terrace] is ten handbreadths higher than the other, one should leave pe'ah [separately] for each terrace. If the heads of the rows are joined together, he should leave one portion of pe'ah for the entire area. If they were less than ten handbreadths higher, he should leave one portion of pe'ah even if the heads of the rows are not joined together.
[The following rules apply] if there was a rock covering the surface of the entire field. If he must lift up the plow from one side and place it on the other side, it is considered an interruption.13 If not, it is not considered an interruption.

When a person sows a field that has trees - even though he sows it in squares14 between the trees and thus the entire crop does not come together as one - he should give one portion of pe'ah for the entire field. For it is known that it is one field; it is only the place of the trees that causes the crop to be divided.15

When does the above apply? When all ten trees were located in an area in which a se'ah [of grain can be sowed].16 If, however, all ten trees were located in an area larger than that in which a se'ah [of grain can be sowed], he should leave pe'ah from every square separately. For the trees are far apart and they did not cause him to sow the field in squares.17

Similarly, if squares of onions [grow] between vegetables,18 one should leave a single portion of pe'ah for all the onions even though the vegetables grow between them and cause them to appear as separate squares.19
יוְכֵן מַלְבְּנוֹת הַבְּצָלִים שֶׁבֵּין הַיָּרָק נוֹתֵן פֵּאָה אַחַת לְכָל הַבְּצָלִים. וְאַף עַל פִּי שֶׁהַיָּרָק מַבְדִּיל בֵּינֵיהֶן וּמְשִׂימָם מַלְבְּנוֹת מַלְבְּנוֹת:
[The following laws apply when a person] sowed an entire field with one crop, but when certain places in the field began to dry out, he uprooted or pulled out the crops that had dried out on either side until the fresh crops appeared as separate blocks. If it was customary for people to sow that crop in individual rows, e.g., dill or mustard seed,20 he should leave pe'ah for each individual square, for an observer would say: "It was planted in separate rows."21 If it was a species that was usually sown throughout an entire field, e.g., grain or legumes, he should leave one portion of pe'ah for the entire [field].22

When does the above apply? When there were dried out portions on either side and the fresh portion in the center.23 If, however, the fresh portions are on either side and the dried out portion is in the center, he should leave pe'ah separately for the dried out portion and the fresh portions.24
יבבַּמֶּה דְּבָרִים אֲמוּרִים כְּשֶׁהָיָה יָבֵשׁ מִכָּאן וְיָבֵשׁ מִכָּאן וְלַח בָּאֶמְצַע. אֲבָל לַח מִכָּאן וּמִכָּאן וְיָבֵשׁ בָּאֶמְצַע מַנִּיחַ מִן הַיָּבֵשׁ בִּפְנֵי עַצְמוֹ וּמִן הַלַּח בִּפְנֵי עַצְמוֹ:
[The following law applies when a person] sowed a field with onions, beans, peas,25 or the like. If he had the intent to sell some of the fresh produce in the marketplace and leave part of the field to dry out and to be put aside in storage, he is obligated to leave pe'ah separately for both the portion he sells and the portion he harvests for storage.26 For [produce sold in] the market and produce set aside in storage are considered as two separate types.

When a person sows his field with one species, he should leave one portion of pe'ah even though he collects the crops in two grain heaps.27 If he sows two species, even though he makes only one grain heap, he should leave pe'ah for each species separately.

[The following law applies when a person] sows two types of the same species, e.g., he sows two types of wheat28 or two types of barley. If he stores them in one grain heap, he should leave one portion of pe'ah. If he stores them in two grain heaps, he should leave separate portions of pe'ah. This is a halachah communicated by Moses from Sinai.29

When brothers have divided [the estate they inherited], they should leave pe'ah separately. If later30 they joined together in partnership, they should leave only one portion of pe'ah.31 When partners who have harvested half of a field break up the partnership, [one taking the grain that was harvested already and one taking the standing grain,] the one who took the grain that was harvested does not separate anything32 and the one who took the standing grain is required to separate only for the half which he took.33 If, afterwards, they reestablished their partnership34 and harvested the second half as partners, either one may separate [pe'ah] for his colleague's portion of the standing grain from his own portion of the standing grain,35 but not for the portion that was already harvested.36

[There are situations in which pe'ah may be given from different parts of a field for other parts of the same field that were harvested afterwards. For example, the grain of] half of a field ripened to a third of its maturity and half did not ripen to that extent. [The owner] harvested half of the portion that reached maturity.37 Afterwards, the remainder of the field ripened to one third and then he completed the harvest of the first half that reached [a third of its maturity] previously. He may separate [pe'ah] from [the crops] harvested first for the middle portion38 and from the middle portion on the first portion39 and on the last portion.40

[The following laws apply when a person] sells separate portions in his field to different people. If he sold his entire field, each one of the purchasers should leave pe'ah for the portion that he purchased.41 If the owner of the field had begun to harvest his field and sold a portion and retained a portion, the owner of the field should leave [the amount of] pe'ah appropriate for the entire field. [The rationale is that] since he began harvesting [the field] he became obligated to [separate pe'ah for] the entire [field].42 If he sold [the portions of the field] before [he began harvesting], the purchaser should separate [pe'ah] for the portion he purchased and the owner for the remainder.

Only a high fence that separates between [the branches of] the trees divides an orchard with regard [to the laws of pe'ah]. If, however, the fence separates on a lower level, but the branches and the trellises are intermingled above and touch the top of the fence, the orchard is considered a single entity and [only] one portion of pe'ah should be given.43

[Different rules apply] if, however, those on the extremes can see those in the center, but those on the extremes cannot see each other, he may separate from those on the extremes for those on the center and from those in the center for those on the extremes.46 He may not, however, separate from those on one extreme for those on the other extreme.47

[The following laws apply to] olive trees: All the trees on one of the sides of a city, e.g., all of the olive trees on the entire western side or the entire eastern side of a city are considered as being from one field and one portion of pe'ah should be left for all of them.

A person who harvests a portion of his vineyard from either side in order to lessen [the demand] on the vines so that the other clusters will have more room and increase in size is called one who reduces.48 We already explained49 that a person who harvests from one side is not considered as one who reduces. Therefore he must leave the amount of pe'ah appropriate for the entire field even though he harvested [with the intent of selling the grapes in] the marketplace. If, however, he reduces [the produce on the vines with the intent of] selling [the produce] in the marketplace, he should not leave pe'ah for the produce that he took off.50 [Nevertheless,] if he reduces [the produce on the vines with the intent of] taking it home,51 he should leave the amount of pe'ah appropriate for the entire field from [the grapes] he left to be trodden for the vat.
