No PR does not effect our adsense earning cause its just effect our page rank in Google and will get good visitors from search engine soon ...
That line made my day. To the OP: No, PR does not affect AdSense in any way at all. Don't worry about it!
Just out of curiousity...you have the option of putting your ads (ie, your Publisher ID) on a PR5 site about shoes or a PR1 site about shoes...which would you choose and why?
Indirectly, possibly. If your PR is nonexistent (i.e. you have a new site with no backlinks), you'll usually be ranked pretty low in the SERPs and won't be receiving much traffic. No traffic = No adsense revenue. That's quite a stretch, though. It won't effect you directly at all.
Ah, but what is PR sometimes an indicator of but traffic...Recall that I also said both sites were the same niche so keyword doesn't matter. If it were sight-unseen (not that I would do that without looking at the sight but just for sake of discussion) I would choose the PR5 site because one of the reasons it is a PR5 site is probably because of traffic, ie from ranking and links. The clicks themselves probably won't earn anything more than if they were from the PR1 site, but with the higher traffic, you would likely get a LOT MORE CLICKS, thus your earnings would likely be greater.
