My 2 cents.
I wouldn’t be that confident on effect of reduce nitrogen on lowering size 
In our trials, with very good soil conditions, and good climate (well... 
usually), leading to nitrogen release from the soil, and nitrogen storage in 
wooden tissues :
- We get a very slow impact of reducing nitrogen levels let’s say about 5 years 
to notice a measurable effect.
- In the 6-7 years range, we see a reduced fruit set, a better effect of 
thinning agent which means less fruit and as you imagine, better fruit size.

Of course in skeletics soils with low levels of organic matter it could be

Root pruning: YES
Withhold nitrogen: YES
Minimize dormant pruning, do some summer pruning (but don't remove fruit): YES
Use Apogee: YES
Over-crop: YES maybe, but use NAA and/or Ethrel to promote return bloom 
Use B.9 rootstock (as opposed to M.9): YES
Make sure you have enough variety to pollinate: YES

I found Morren's Jonagored Supra (Willow Drive) grown on B.9 rootstock to be a 
very nice Jonagold strain. Good crops without too many large fruit. Still have 
to watch biennial bearing. I would plant that strain in a heartbeat if I want 

Did you hear New England Apple Association is going to brand Jonagold apples 
grown in New England? Not sure, however, what they are calling it?

Any other ideas out there?

                I don’t know whence the observations or measurements have come, 
but I saw a rootstock comparison
        in which G202 was said to produce “smaller fruit size.”   For the 
reason you mention, I hope this is true, and of
        more than just statistical significance.  I suspect that if it were a 
practical difference, we would have heard more
        about it.
