Research on the influence of pruning on wood maturation, photosynthetic yield, quantitative and qualitative production, and profit in grapevine growing
Keywords:
grapevine, mechanization, physiological balance, quality, winter pruningAbstract
The research focused on winter pruning in grapevine, a very important and costly technological phase, that decisively influences both the physiological and biological balance of the vine, as well as grape yield, grape quality, and last but not least, the economic indicators for vineyard management. The experimental plots organized in the experimental trial were: V1 (Control): standard manual pruning; V2: light pruning; V3: mechanized hedge-type pruning. The research was carried out on four table grape varieties and two wine grape varieties in a vineyard at full maturity located in the Buzias-Silagiu area. Winter pruning is the most expensive technological phase due to the difficulty in finding qualified labour and the challenge of mechanizing winter pruning and establishing crop loading, without affecting the longevity of the vines, the quantity and especially the quality of the grape production. During research, conventional pruning (V1) provided the best results for all the indicators analyzed. Mechanized pruning remains an option that should only be applied under conditions of strict necessity, even though it offers the lowest costs.
