The FAO wheat site offers one page per country, so I've taken the transpose to produce the table below.

One ton per hectare is 9.5 bushels per acre, these are figures from 2000.

It has been pointed out that they're in intercalated alphabetical order, which is in almost no case the right order to use. You can pick them up more usefully at Google Spreadsheet.

...without yield/ha figures, mind.

The blue lines should be equal kilotons, but I haven't troubled to work out what units they're in.

That's an excellent graph, thanks! What tool did you use to make it?

[the lines are 100kT, 1MT, 10MT, 100MT]

It's an Excel spreadsheet. The labels are made with the AppsPro Chart Labeler, a very useful add-in utility from Rob Bovey.

That's an interestingly random set of figures. If we assume that wheat is easy to trade and pretty fungible, then it would make sense to grow it in places where the yields were highest, if costs were strongly dependent on yeild. There should be a scatter of dots (depending upon fertility) along some horizontal line somewhere near the middle of the graph.

Presumably high costs per yield push countries up the graph, and (incidentally) to the left [eg high labour costs] (so that fields with potential for lower-end yields are not profitable in those countries), whereas subsidies on production push the country down the graph and (incidentally) to the right.

It would be interesting to see [livejournal.com profile] del_c's graph with this line drawn on it: total square kilometerage (x) times yield (y) equals total world demand.

I'm not sure what total world demand for wheat means, given that it's fungible against cereals-in-general, especially if what you want to do is feed it to a pig or ferment it down to bioethanol.

http://www.indiancommodity.com/Gen/wheat.htm says 550MT/year wheat production, of which 60% eaten by humans, so 300MT total world demand (fifty kilos per human per year; wheat produces about its own weight in wholemeal bread, so that's a loaf per human per week). That's a blue line half as far to the right of the rightmost one as the rightmost is from its left neighbour.

Total current consumption, then. You're right about the fungibility, I wasn't sure of the extent to which it was replaceable with other cereals. I'd not thought of the animal feed consumption (shows me what good I'd have been as cantral planner!). We need some formally indifferent pigs, clearly!

Even if it's fungible, though, I think the yield levelling should still take place, because wheat is easily transportable across markets, so each of the countries should be little more than a terroir and legislative regime in a single production market.
