A person owns two adjacent fields sown with the same crop. He harvests one entirely and wishes to leave the pe'ah for both fields in the second field. Is this permitted?
Halachah 1 rules that pe'ah from one field cannot fulfill the obligation for another field, derived from 'Do not completely remove the corners of your field' — each field requires its own pe'ah.
Question 2
What minimum width must a public thoroughfare be in order to divide a field into two separate units for pe'ah purposes?
Halachah 3 states that a public thoroughfare must be sixteen cubits wide to constitute a separation, while a private path requires only four cubits — because the public has many paths and won't follow a narrow one consistently.
Question 3
A person sows two varieties of wheat — thick-kerneled and thin-kerneled — and stores them together in a single grain heap. How many portions of pe'ah must he leave?
Halachah 15 rules that two types of the same species stored in one grain heap require only one portion of pe'ah — this is a halachah communicated by Moses from Sinai (oral tradition with no direct Torah source).
Question 4
Brothers who divided an inherited field subsequently decide to re-enter partnership before the harvest. How should they leave pe'ah?
Halachah 16 states that when brothers who divided an estate later join together in partnership before the harvest, they leave only one portion of pe'ah — the same rule as any other partners.
Question 5
A vineyard owner harvests clusters from his vines specifically to thin them out and improve the remaining clusters, and he sells the removed clusters in the marketplace. Is he obligated to leave pe'ah for the thinned clusters?
Halachah 23 exempts vineyard thinning (reducing) from pe'ah when the owner's primary purpose is to benefit the remaining vines — the marketplace sale is incidental. However, if he takes the produce home (demonstrating intent to harvest), he must leave pe'ah for the entire field.
