Sorry. Legume style nodules are wishful thinking when it comes to tomatoes.

Those tomatoes have a serious case of root knot nematodes. And that's true in spite of any good harvests you may have had.

More clues that they're not legume nodules.
-- Legume nodules are all about same size; then when cut, are pink inside.
-- Nematode lumps are irregular and much larger.

Sorry.

jean001 is dead right. The nitrogen nodules you see on legumes don't look anything like that. They look like grains of salt, kinda.
