Fertility and Productivity Indices at Some Grape Varieties for White Quality Wines in Climatic Conditions of Vineyard Tarnave, During the Year 2010
Abstract
In order to estimate the quantity of crop in a vineyard, the farmers can use the fertility and productivity elements. The four grape varieties: ‘Muscat Ottonel’, ‘Neuburger’, ‘Traminer roz’ and ‘Sauvignon blanc’, registered value between 0.55 and 1.26 for relative fertility coefficient, 1.71 and 2.08 for absolute fertility coefficient. The highest value of relative productivity index was calculated at ‘Traminer roz’ variety (86.94), and the lowest at ‘Neuburger’ variety (58.85).
