Abstract

The study of the impact of different vine loads on the agrobiological, economical, and technological characteristics of the Ribier variety was carried out in 2020 and 2021 with the aim of determining the optimal load for this variety. The tests were carried out in the experimental vineyard of the Biotechnical Faculty in Podgorica. Four different vine loads with fertile buds were applied, namely 8, 12, 16, and 18 buds. The results of this study have shown that the applied loads had a significant impact on the examined parameters of the Ribier variety. The results obtained on the average yield of grapes have shown that the lowest value of this parameter was found in the variant with a load of 8 buds - 4.2 kg/vine, while the highest grape yield was recorded for the variant with a load of 18 buds (7.0 kg/vine). V1 had the highest average cluster weight (396 g), while V4 had the lowest cluster weight (325 g). The content of sugar in grape juice also varied significantly under the influence of the load on the vines. The highest sugar content was recorded in the variant with a load of 8 buds - 16.1%, and the lowest in the variant with 18 buds - 14.7%. The acid content did not differ significantly between the tested varieties.
