In this article:
Earlier reports had described a method harvesting and drying Sultana grapes, involving the severing from the vine at harvest time the one year old canes.
Yield and vegetative growth were not affected measurably when vines had been harvest pruned once.
This article reports on experiments conducted to examine the effects of harvest pruning for several consecutive seasons. It also includes results from trellis treatments designed to facilitate the pruning of vines in full leaf.
The experiments have shown that harvest-pruning will not lead to a breakdown in the productivity of the vine, even if it is practised for as long as seven consecutive seasons.
