Making a modern fruit growing cannot be conceived without providing a corresponding hydric regime that fruit species need. Even in areas with abundant precipitation should be taken into account that they are unevenly distributed throughout the growing season and that there are critical moments in which trees need to consume water. Low humidity and lack of water can harm large harvest this year or next year to the fruit formation. Taking into account this aspect, in the present study, we wanted to put out the effects of application of modern methods of water located on the behaviour of apple fruit valuable in terms of the south-eastern Romania, where are encountered optimal culture conditions and find the best recommendations for production. The content of this paper is based on research, observations, experiments, extensive research of issues prioritized and data processing including the whole range of issues, starting from the foundation of the application irrigation necessity. As a result, the entire work is based almost exclusively on research findings on the effect of irrigation and fertilization level on apple at Moara Domneasca farm conditions.Factor A-variety: Generos and Florina. Factor B-irrigation norms: non irrigated witness; drop 2 litres / hour; drop 4 litres / hour. FactorC-fertilization levels: 2,5 kilo Megasol or 5 kilo Megasol. The irrigation level resulted in production increases and bonuses obtained as very significant statistically for the two levels of irrigation applied. The highest yields were recorded in variants where rules were applied 4 l / h, with production increases of 40.1%, and increases the harvest of 5.52 t / ha.
