At one time people were grafting cuttings from tomato plants onto the top of
potatoes to get two crops from the same planting.

I believe this was only experimental in a laboratory.

I have no idea what this did to the yield of the potatoes - I would have
thought there would be a major conflict between storing up food in the roots
and getting as much food as possible into the fruits.

It wasn't satisfactory.
