Irrigation with a drip system uses less water than sprinkler irrigation. The foliar fertilization is an important unconventional and unpolluting measure, meant to increase fruit crops through an ecological process suitable for sustenable development. Technological variants were studied using localized irrigation (b2) and irrigation associated with foliar fertilization (b2c2) on the behavior of three varieties of apple 'Romus 3'(a1), 'Generos'(a2) and 'Ionathan' (a3) (Malus domestica Borkh.), grafted on M9, with different periods of maturation, in terms of the South-East of Romania, where optimal conditions are encountered. From this paper, studies found that a version of localized irrigation technology is associated with foliar fertilization (b2c2) and had influence on the characteristics of existing trees, i.e. tree height and trunk section area (TSA) on the production of fruit but also on the quality of the fruit items (average weight of the fruit, soluble dry matter, acidity and firmness).
