As a part of the VITCLIC project on wine growing and winemaking experimental field at the Faculty of Agriculture in Jazbina, research on ampelotechnical procedures of grapevine is being carried out with the aim of adapting them to the observed climate change.
The attempt to remove some of the leaves from the grape zone in four different terms (prior to flowering, just after flowering and planting, at the beginning of the shrubbery) at Merlot varieties is monitored as part of the partial defoliation by changing the meteorological conditions within the vine's microclimates, affects the dynamics of ripening the grapes and consequently its quality. The effect of defoliation on yield varies depending on the time and intensity of the implementation, and the defoliation should have a positive effect on the differentiation of buds and yield in the following year.
