VARIABILITY OF FRUIT PRODUCTION AND PRODUCTIVITY FEATURES UNDER THE INFLUENCE OF SOILS MAINTENANCE SYSTEMS IN THE ORCHARD
Journal Title: Natural Resources and Sustainable Development - Year 2013, Vol 3, Issue 1
Abstract
Naturally, new apple plantations established in the last 10 years include other varieties than those that are traditionally grown. These varieties are most of Western European origin and already know a considerable expansion in horticulture developed EU countries. All five new varieties of apple (Rajka, Rubinola, Topaz, Otava and Goldstar), tested in the research, find in the respective basin, favourable pedoclimatic growing conditions All new varieties prefer bare fallow (classic or with herbicide on the row), systems in which the fruit production and its quality are high. For the varieties discussed, planted in super intensive orchards (2000 trees / ha), fruit load regulation is absolutely necessary when seeking large and quality productions which can be sold profitably as dessert fruit. Five varieties of apples, less widespread in Romania, but widely spread in the European Community countries, were studied in terms of many particularities of trees development, of productivity and fruit quality. These varieties are: Rajka, Rubinola, Topaz, Otava and Goldstar, and we can find them on SC. Delifood S.R.L. plantation from Urvind, Bihor county. The plantation was founded in 1999, with tress grafted on M9 rootstock. For the planting distances used 4 x 1.20 m, we got a density of 2083 trees/ha.
