A nuke would typically detonate in the air or on the surface of a planet. Powerful enough and in sufficient numbers, they would only glass the surface of a planet rendering it inhospitable. In order to (conceivably) destroy a planet with nukes, not only would they have to be much more powerful than anything we could build today, but you'd have to drill several thousand kilometers into the mantle and detonate said nukes in the planet's core. And even then you'd need a frickin LOT of nukes. Granted, it probably wouldn't be beyond the Dominion's ability to build such weapons, seeing as how they already blow up entire planets during terraforming accidents, but just think about how much time and resources such a project would require. And that's assuming you were even able to clear the zerg airspace sufficiently to be able to carry out such a bombardment.
Oh and FWI, there was a bit of a retcon RE: the nukes that glassed Korhal. They weren't launched from Tarsonis, they were launched from orbiting battlecruisers.
