World record yield? Not certain. Do know that the yield benchmarks are moving up in the Northwest. Some growers now manage Gala for an average yield of 100 MT/Ha, and have a target benchmark of 130 MT/Ha. In the 2012 crop many blocks of all different varieties approached the 100 MT/Ha expected yield. At the WSU fruit school in 2008, the standard yield in the economic presentations were 50 MT/Ha with a target of 70 MT/ Ha.
The highest sustained yield discussed in the Northwest has been Granny Smith on Mark rootstock at 140 MT/Ha or ~140 bins with 900 pounds of fruit per bin. The rootstock influences the spur density down the limbs, so Mark has been the standard for productivity. The replant tolerant Geneva rootstocks such as G.41, G.935, G.214, G.210, G.30 have the crop density equal to or better than Mark. The discussion of yield is evolving from total yield to yield of fruit with high and consistent consumer acceptance. Highly productive varieties such as Fuji and HoneyCrisp may need to implement rigorous crop load management by counting spurs at pruning, flowers at bloom and fruit in June to cap yields at 80 bins or less, in consistent, full canopy blocks. The goal is to have crisp, juicy, great flavor fruit every bite.

The last record I have ever heard quoted was a7 year old block of Granny smith apples from New Zealand around 130 metric tonne per hectare in the early 1990's.does anyone know where a person might source such info or r what the current record might be ?

I''ll plant 5x12 and give you a report as the next few seasons go by.

The trees have done very well, however, they are larger than B.9 and M.9. Planting 3-4 feet apart is running into some crowding issues. They have been precocious, but I would plant them 5-6 ft. apart using a vertical axis type training. Trees I believe have come from Cameron Nursery.
