Soil Type Influence on Yield Quantity and Quality at Grape Varieties for White Wines Obtained in the Viticultural Centre Blaj

The study was conducted in 2011-2012 at Reasearch Station for Viticulture and Enology (SCDVV)Blaj and aimed the pretability of varieties for quality white wines (Fetească regală 21 Bl, Sauvignon 9 Bl,Traminer roz 60 Bl, Muscat Ottonel 12 Bl and Neuburger 10 Bl) in pedogenesis conditions of entiantrosoland eutricambosol soil from Târnave vineyard. In terms of varieties were conducted observations andmeasurements on bud viability, fertility and productivity elements, production obtained per vine andcrop quality in terms of climatic conditions of the two years analyzed. Fertility and productivity arecorrelated with each other and directly affects the production of grapes. Thus, agro biological value wasdetermined in conditions of the varieties studied in Blaj wine center (2011 and 2012) on the two soiltypes. In terms of lithology, Târnave vineyard is characterized by the predominance of clays, marls andPanonian and Sarmatian gravels (ridges and hillsides) and the loess (Pleistocene and Holocene terraces)of the sediments formed soil formation.We determined the main agrochemical soil fertility parameters(pH, total nitrogen, phosphorus and potassium). Blaj vineyard has a long tradition, especially in thedirection of the cultivation of grapes for the production of quality white wines, while those studied inthis paper, rich assortment of varieties for white wine vineyard Târnave
