Integrated management of vineyard plantation - comparative study of olivia variety and feteasca neagra 4vi clone

Knowledge of the biological, ecological, technological and managerial peculiarities applied in vineyard, as well as their integration in the context of sustainable development and the economic and resource crisis, is a permanent concern of the specialists working in this field of activity. This paper presents some of the results obtained from the research carried out within the ICDVV Valea Calugareasca during three agricultural years (2017-2019) regarding the management of the vineyard. The behaviour and adaptation to climate change of the Olivia variety and the Feteasca neagra 4VI clone were observed. These were chosen due to the fact that both were obtained at ICDVV Valea Calugareasca, they are intended for winemaking, they have the same ripening period (IV-V, depending on the characteristics of the agricultural year), and their production potential is similar (9.3 t/ha in the variety and 10.0 t/ha in the clone). The results indicate that, under identical eco-pedological and technological conditions, the Feteasca neagra 4VI clone adapted better to the climatic conditions of the research years, managing to obtain 9-16% higher yields compared to the Olivia variety.
