Hello In our conditions 'France South West' If we speak about an experimental apple plot with tremendous pollination, space and light, an easy variety, perfect row and tree spacing, a full vegetative hedgerow on M9 stock, on one specific easy year with plenty of work to thin at the best time, we can reach heavy crops 120MT and more per ha. If we speak about a 5 year average in a commercial harvested orchard the 100MT are achieved only on easy varieties (Granny, Fuji...) in our best conditions If you integrate nonproductive years, climate hazards, then an average of 70 MT on the life of orchard is a good target. If you include all varieties, all ages, all years à 60MT is not that easy to reach... as you all know...
About crop and quality: we integrate a sensory evaluation lab in our research Center and the specialist panel is able to evaluate the impact of yield (acceptable range) on quality and the depressive effect of high yields on soluble solids. But the impact on taste may be less compared to some storage technics effects. If we speak about acceptance evaluation checked with consumers, they are very pleased with apple quality. In our areas 80% of apple sales are through supermarkets. Over decades (we make a survey every 4-5 years called 'apple barometer') more than 80% of consumer are saying that they are pleased with product quality with stable trend. This is not at all the situation for all fruit species. Peach quality (e.g) is criticized a lot by consumers. The more impressive orchard yields I saw on apple trees in my technical life were in New Zealand.

Around here our record yields are about half of what you are reporting. However, we too can go further I think. Quality is important for returns also though. I remember seeing research from Holland quite a few years ago, for Holland, which showed little quality change (as measured by soluble solids) when yields of Jonagold went to about 65 metric tons per hectare. From there to 85 metric tons, as yield increased, soluble solids dropped. It would indicate that for that particular system, climate, variety etc., some sort of plateau was being reached.

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 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.
