| Title : | THE INFLUENCE OF CLIMATIC FACTORS ON THE LEVEL AND QUALITY OF YIELD OF VRANAC VARIETY IN PODGORICA VINEYARDS |
| Abstract : | Due to the favourable climatic and soil conditions, the vineyards of Podgorica have always been known as a very favourable area for successful cultivation of grape vine. The influence of climatic factors on the grape yield, weight of vine cluster and quality of grape vine of Vranac variety were studied during 2003, 2004 and 2005. The estimation of grape quality is done on the basis of sugar content and total acid content in the must. The highest yield of grape, as well as the mass of the cluster is achieved in 2005 (1.52 kg/m2, i.e. 239 g), while the lowest yield (1.13 kg/m2) and cluster mass (173 g) were measured in 2003. The highest sugar content and the level of acid in must were measured during 2003 and the lowest content was found in 2005. In 2003 with the highest average temperature during growing season, deficit of rain falls was measured in comparison with that period and with climatic normal, but also in the relation to the actual needs of the vine grapes for water. Such yield and the quality of grapes in that year were in direct concordance with the weather conditions. The average grape yield in the three year period was 13.5 t/ha, the sugar content about 24%, the acid level 6.10 g/l, which means Vranac variety from this vineyard had the optimal production conditions. Although these three years were warmer with greater amount of rainfall in comparison to long term average, a more detailed analysis of differences between monthly values of climatic parameters during that period, especially during growing period, can explain differences in yield and grape quality. |
