Proper irrigation is one of the≥key factors ofmaintaining a healthy and≥economical productive cherry orchard. Over irrigation can slow the growth of the roots and can induce excessive vegetative vigor, but applying the deficit irrigation method can result into drough stress. The reproductive response of a ten years≥old cherry trees orchard under the temperate continental climate to deficit irrigation was studied in a private and commercial orchard≥located in the East of Romania for 1 season. Three irrigation treatments were establish: 1) irrigation by control, 1 lateral, 2.3l/h dripper, 0.50 cm spacing, irrigation rate = 1.02; 2) irrigation by low flow, 2 laterals, 0.7 l/h dripper, 1.0 m spacing, irrigation rate = 0.62; 3) irrigation with 2 laterals per row, 2.3l/h dripper, 1.0 m spacing, irrigation rate = 1.02. The phenological phases of sweet cherry trees like flowering, fruit≥and vegetative growth is influenced by the different irrigation methods and after the evaluation these different irrigation strategies resulted reproductive response as fruit size, fruit yield, leaf. Observation indicate that exceedingly low flow irrigation throughout daylight hours may contribute to irrigation efficiency. In the market we can choose to use drippers with low flows that have not yet been introduced into orchards in significant scale wordwide. The purpose of the observation is to evaluate the effect of continuous irrigation method on cherry trees and the applicability of low flow dripper in orchards.
