In this paper are presented the results of two years study (2014-2015) of productivity elements and quality of grape of žižak variety in Podgorica wine region. Research was carried out in the vineyard of the Biotechnical Faculty in Podgorica, which is in full productivity phase. The results show that this variety continues to show good production characteristics, despite greater negative effect of climate changes. Environmental factors had no significant effect on the percentage of emerged and fruiting canes. A larger number of inflorescences per emerged and fruiting cane (1.20, and 1.44, respectively), grape yield and cluster weight were achieved in 2015 (1.4 kg/m2 and 156 g). In this year a higher sugar content (22.1%) was measured. Significantly higher acid content (6.8 g/l) was measured in 2014, as a result of the heavy rainfall during the growing season. These studies show that the elements of fertility and quality of grape žižak were in accordance with the weather conditions in the studied years.
