Sweetcorn

Has anyone tried gowing corn the way the native Americans do? Dig holes eight inches deep and put 8 - 10 seeds per hole, then thin to four or five when they come up. Probably too deep for our generally wetter soils, the depth is for protection in desert conditions I believe, but growing them in a clump seems a grassy thing to do, and it is a grass, albeit a big 'un.
