Actually that would make sense. That would mean that Turkey would me more or less over Nurn, which would allow wheat to grow there (it's Mordor'as breadbasket, after all)

And just to be a bit silly, A funny thought ocurred to me. I wonder if all of the peoples of middle earth selected thier grain strains to fit thier own views of beauty. The children of Durin presumably preferred trading for grains with long beards, while others would seek ones with short stiff ones, and of course, Gondorians would demand thier wheat and barley be beardless*. The men of Numernor would want Poulard wheat; tall and great grains for tall and great men. Hobbits on the other hand would probably most favor in club wheat; small and compact. Sauron's fields would presumably be filled with black wheats. Giant whippy Tibetan barleys for the men of Rohan, to ride thier horses through majesticly (and they are good for beer brewing). And of course Saruman, with his love of all things mechanical, must favor rivet wheat.

*The awns (those long hairy things) on the top of an ear of wheat are collectively called the beard. Some wheats/barleys have long beards, some have short beards and some have no beards.
