We call that peck work.How many names are there for the runs up and down a field when the headland is encountered at an angle, so a triangle shaped piece is left? Scoots, Running work, Short work, etc I'm sure there are load more.
Same goes for headlands: end rigs, turn rows, outside breeds. In the US most seemed to call them the end rows, but that was mainly on corn/maize where they literally were rows
