ABSTRACT
Amounts of precipitations and their irregular time in south-eastern of Romania have as results many years with high soil water deficits affecting fruit yield quantity. In order to quantify the effects of drip irrigation on the behavior of 17 apple cultivars, investigations were performed in the experimental field of USAVM Bucharest. The research presents the results of determinations and observations carried out regarding the phonological stages of three apple cultivars and the yields per tree and unit surface under the application of drip irrigation associated with fertilization (irrigation). Also, the determinations and observations regarded the fruit weight for apple cultivars, as well as the proportion of fruit production able to be stored from the total production of fruits harvested. The implementation of drip irrigation aimed at increasing the amount of higher quality categories (extra quality and quality I) of fruits delivered for fresh fruit market. By sorting the fruits in categories of quality after harvesting and storing, that ensures a steady supply of fruits in network distribution, depending on fresh fruit market needs. The implementation of drip irrigation in experimental plots organized in experimental apple orchards for analyzed varieties, has contributed to achieving an increase in production and fruit quality, an earlier fruits ripening period as well as an increase of the percentage of apple and peach fruits able to be stored from the total production of fruits harvested.
