The aim of this study was to study the impact of crop load on the yield and grape quality of ‘Merlot’ and ‘Vranac’ (Vitis vinifera L.) in Trebinje vineyard. The crop load levels studied in this trial were 9 buds (V1) and 12 buds (V2) per vine at each variety trained on Lenz-Moser bilateral cordon system. The impact was determined by measurements of yield per vine and grape quality characterized by the contents of total soluble solids, titratable acidity, total phenolics, total flavonoids and by total antioxidant capacity. The measured parameters of grape quality of ‘Merlot’ and ‘Vranac’ were not influenced significantly by crop load levels. V2, compared to the V1, showed the potential for increasing grape yield only for Merlot variety under experimental conditions. The results of this study also showed a positive correlation between total phenolics/flavonoids and total antioxidant capacity of grape berries in both varieties, regardless of crop loads applied.

Effects of Municipal Sewage Sludge Application on Soil Salinity, P and Heavy Metal Concentrations in Four Different of Foliar and Soil Nitrogen and Zinc Treatments on Zinc and Iron of Effects of Foliar Nitrogen and Zinc Treatments at Grain-Filling Period on Nutrient Transport to Wheat Grains Abstract The two-year experiment (2008 and 2009) on new introduced table grape variety Victoria was carried out in the commercial vineyard in the conditions of Nerezi vine district, Capljina Municipality. This study the influence of different bud load levels was investigate on grape quality of cv. Victoria under given environmental conditions. The experiment was conducted by random selection method in four variants with different bud load levels per grapevine (19, 24, 28 and 33 buds per grapevine), each variant being repeated four times with 6 vines repeating. Variant II(24 buds per grapevine) had, in two-year experiment, the average value of the largest cluster weight (599.78 g), the cluster berry weight (573.25 g), and the mass of the cluster stems (12.5 g). The average content of sugar in the grape must was slightly higher in variants I and II (14 %) compared to other variants, while the highest average content of total acids had variant III (4,06 g/l).
