RESULTS OF THE EXPERIMENTS FOR THE IMPROVEMENT OF THE FERTILISATION OF THE FUNCTIONAL FEMALE FLOWERED GRAPEVINE CULTIVAR ‘KÉKNYELÜ’

The name of the grapevine cultivar ’Kéknyelű’ has become inseparable from the name of the Badacsony vine region, its fame is well known beyond our borders.
During the history of the vine region it was known as a cultivar, which provided a poor yield, but top quality.
Considering the professional experiences, we set up experiments for the exploration of the cultivation value and fertilisation relations of the cultivar ’Kéknyelű’. In the experimental plots we examined the effect of the following treatments:

• training-systems

• pollinator cultivars,

• plantation combinations,

• bunch isolation.

Summarising our results it can be established, that the fertilisation, and through that the crop of the ‘Kéknyelű’ is significantly effected by the training-system, the pollinator cultivar, and the presence of the strange pollen. Besides it can be established, that the ‘Badacsony 36’ candidate cultivar often effected the crop more favourably than the ‘Budai’. At the same time, the investigated treatments did not effect significantly the must degree and the titratable acidity of the must.
Summarising our results it can be established, that the applied treatments can considerably improve the fertilisation of the ’Kéknyelű’, thereby they positively effect the quantity of the crop, so the cultivar ’Kéknyelű’ can provide a competitive accomplishment in today’s changed marketplace.
