- Efficient use of water resources by promoting proper irrigation methods in representative orchards.

- Knowledge of water and fertilizer distribution in soil depending on irrigation (fertigation) methods used.

- Determining crop evapotranspiration in the specific-for-Dobrogea fruit species in order to decrease water losses by applying irrigation.

- Increasing fruit yield & quality by applying irrigation (or fertigation).

- Use of localized irrigation methods (drip irrigation and microsprinkler irrigation) to alleviate droughts and reduce the desertification risk that increased lately.


Results obtained for Dobrogea

-   Crop evapotranspiration ranged between 220 mm (as non-irrigated) to about 470 mm (in drip irrigation plots) for apricot.

- Fruit yield was significantly correlated with crop evapotranspiration; this means a positive response of the trees to water application by irrigation;

- The highest fruit yields in apricot were obtained in microsprinkler irrigation treatments using about 150 mm of water during the growing season; however, drip irrigation treatment produced the best results from the economical viewpoint.
