Oddly enough I came across a tiny field of rape a couple of years ago on a small island off the west coast of Ireland. The whole thing was surrounded by substantial walls, and measured about 60 yards by 30. It looked far too small for a commercial crop, yet had been carefully planted in one of only a very few patches of good land. Bit of a puzzle.


As Big Al points out, the yellow crop may be mustard. This is sometimes used as a "cover crop" to add nutrition to the soil before planting potatoes.
