3,137. Planting on a Mountain

Hilchos Matnos Aniyim 3:5

If locusts ate a field in its middle, or if ants destroyed the crop there, if one plows the part that was ruined, it serves as a separation between the parts of the field.

Hilchos Matnos Aniyim 3:6

If someone one plants crops on a mountain that’s not level ground, but rather it has bumps and hollows, even though he can’t plow it or plant it all at once, needing to plow the bumps and the hollows separately, it’s still considered a single field. The owner leaves one peah at the end of the mountain for the whole mountain.
