I don't really think this is what it was, but I came across a field planted with a crop, the flowers of which were clearly cruciferous (the same shape as oil seed rape flowers) but pale lilac to white in colour. Not as tall and branchy as OSR. Such seed pods as there were, were long and thin (but still immature). No photographs, as I was accompanied by a better botanist, who took away a specimen but has yet to nail it.

Any suggestions?

I suppose it could be bird cover.

From the description it sounds more like sweet rocket, Hesperis matronalis, or a relative.

I would have thought linseed from the flower, but wouldn't expect it to be in flower now and the seeds are not long and thin. Linseed, or flax, can be in varying shades of blue, possibly even purple or pinky, or white.

Linseed isn't cruciferous and the seed pods are round. What were the leaves like?

Lady's Smock or Bittercress? Very early to be in flower, but the mild wet weather might have favoured them. I can't think why anyone would grow either as a crop though. Unless it's a green manure that has been left too long perhaps.

There a some cover crop possibilities here- fodder radish, texel greens? Though again this seems an odd time for themto be in flower.

Is a legume, not a brassica

No, nothing at all like linseed. (Which has blue flowers (round here), not lilac/white)

Much like OSR.
