It IS early, but something to consider as pruning season approaches...
Take a look at this video/interview (link below) with Dr. Patty Skinkis of Oregon State University as she explains/discusses the results of her experiment comparing spur pruning and cane pruning. One of the grower objections to spur pruning, despite its fitness and suitability to mechanization, is lower yields with spur pruning compared to cane pruning. The supposed yield loss was based on lower bud fruitfulness of buds located on the base of the cane that make up the "spur". Check it out for yourself and assess the empirical results that Dr. Skinkis and her team determined.Dr. Patty Skinkis in American Vineyard Magazine spur pruning with no yield loss
